Its position in the drill string assembly is relatively free, and it can be placed in various positions such as tension, neutral point, and compression. It can meet the needs of drilling operations under various operating conditions such as land and sea.
Downhole Motor
Downhole motor (PDM drill) is a volumetric downhole power drilling tool that uses drilling fluid as power and converts liquid pressure energy into mechanical energy.
When the mud pumped by the mud pump flows into the motor through the bypass valve, a certain pressure difference is formed between the inlet and the outlet of the motor, pushing the rotor to rotate about the axis of the stator, and transmitting the speed and torque to the drill through the universal shaft and the transmission shaft To achieve drilling operations.
A progressive cavity volumetric hole bottom power machine, referred to as auger drill.The auger drill, which uses mud and clean water as the power medium and is conveyed to the bottom of the hole through the center hole of the drill rod, is essentially an energy conversion device that converts liquid pressure energy into mechanical energy. During drilling, the auger directly drives the core tube and drill bit connected to the transmission shaft at the bottom of the hole to rotate. The entire drill string is only used as a channel for conveying high-pressure working medium and a rod supporting the counter torque of the drill bit.
Compared with conventional drilling, screw drilling has many advantages, such as greatly reduced drill pipe wear and high drilling speed.It is the main tool for directional drilling and has played a role in the field of drilling.
The auger drill was first used to punch vertical holes, mainly used to drill a variety of directional holes and special engineering holes (such as mine frozen holes). The maximum drilling depth is 9023 meters. At present, the minimum diameter of auger drills in the world is 44.5 mm and the maximum diameter is 304.8 mm. When auger drilling is used for core drilling, a core tube should be added between the drive shaft and the drill bit to take the core
Blow-out preventer(BOP)
When drilling for oil, it is installed on the wellhead casing head to control high-pressure oil, gas and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (closed). When the heavy mud is pressed from the drill pipe, there are four links under the ram, which can replace the gas invaded mud and increase the pressure of the liquid column in the well to suppress the high-pressure oil and gas.
Its type is divided into ordinary BOP, universal BOP and rotary BOP. The universal blowout preventer can be started in an emergency, and can deal with any size of drilling tools and empty wells; the rotary blowout preventer can perform spraying and drilling. In deep well drilling, in addition to two ordinary blowout preventers, plus universal blowout preventers and rotary blowout preventers, three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Large sluice gates usually equipped with ram-type blowout preventers will form a sealed annular space between the pipe string and the wellbore during operation. It can also be used alone in the case of a pipe string Completed well closure, but it will not work a few times, and it is not allowed to use the well for a long time.

Pump Unit
A beam and crank assembly creates reciprocating motion in a sucker-rod string that connects to the downhole pump assembly. The pump contains a plunger and valve assembly to convert the reciprocating motion to vertical fluid movement.
As the beam pumping system rocks back and forth, this operates the rod string, sucker rod and sucker rod pump, which works similarly to pistons inside a cylinder. The sucker rod pump lifts the oil from the reservoir through the well to the surface.
A beam pump is an artificial-lift pumping system which uses a type of reciprocating pump to extract oil from an inland well. Nodding donkeys or beam pumps are a common artificial lift system used in land-based operations.
A pumpjack is the overground drive for a reciprocating piston pump in an oil well. It is used to mechanically lift liquid out of the well if not enough bottom hole pressure exists for the liquid to flow all the way to the surface. The arrangement is commonly used for onshore wells producing little oil.
Because of their characteristic shape and motion, pumpjacks, also called beam pumps, are often given fanciful names such as "lonely birds" and "nodding donkeys." Whatever name you call them, such pumps are critical to crude oil production.

Saigao Gate valves.
Gate valves are primarily designed to start or stop flow, and when a straight-line flow of fluid and minimum flow restriction are needed. ... The disk of a Gate valve is completely removed when the valve is fully open; the disk is fully drawn up into the valve Bonnet.
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance.The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow.
Gate valves are mostly used with larger pipe diameters (from 2" to the largest pipelines) since they are less complex to construct than other types of valves in large sizes.
At high pressures, friction can become a problem. As the gate is pushed against its guiding rail by the pressure of the medium, it becomes harder to operate the valve. Large gate valves are sometimes fitted with a bypass controlled by a smaller valve to be able to reduce the pressure before operating the gate valve itself.
Gate valves without an extra sealing ring on the gate or the seat are used in applications where minor leaking of the valve is not an issue, such as heating circuits or sewer pipes.

Saigao Steel casing pipe
Saigao Steel casing pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity.
Saigao Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors such as the interference-fit Permalok interlocking push-on joint. The Saigao Steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers
Saigao Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc. The utility lines that are run through the Saigao Steel casing pipe are most commonly mounted and spaced within the Saigao Steel casing pipe by using "casing spacers" that are made of various materials, including stainless steel or carbon steel and the more economical plastic versions. The ends of a Saigao Steel casing pipe "run" are normally sealed with "casing end seals", which can be of the "pull-on" or "wrap-around" rubber varieties. Saigao Steel casing pipe is also used in the construction of deep foundations.
Specification
Saigao Steel casing pipe generally has no specific specifications, other than the need for the material to be extremely straight and round. In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strength of the steel pipe being used for casing, and tolerances of straightness and concentricity.
Saigao Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often reclaimed in very good condition and can offer a significant cost savings when compared to new steel pipe. Used pipe is most likely to not have any testing data associated with it and is generally used when the only required specification is a given diameter and wall thickness of Saigao Steel casing pipe.
Fishing tools and crafts
During drilling and completion and workover operations, drill rods, drill collars, casings, tubing strings are stuck or broken, drill bit cones are dropped, logging tools or cables are stuck, cable wire ropes are broken, packers are broken Interruption of normal drilling, workover, and completion operations due to stuck, sand, serious leaks, well collapse, blowout, etc., need to use fishing tools or take special measures to remove leaks, collapse, stuck, spray to resume normal operations. The operation and process of removing leaks, collapses, jams, and sprays is called "fishing."
Slot-Screen-Perforated Pipe
Bridge slot screen have bridge opening arranged in rows and are staggered to reduce the negative effect on the screen's strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded. The sand and gravel can't easily block the slot because of the special bridge style design. This kind of slot screen has great mechanical strength and water entering capacity. Meanwhile, bridge slot screens are light, cheap and easily operating. Regarded as the best choice of well tube filter, they are widely applied in a variety of fields in the developed countries.
