The choke valve, a main component of Christmas tree, is design to control production rate of the oil well, with working pressure up to 15000psi. Choke valves can be classified as follows: adjustable choke valves and positive choke valves. By rotating hand wheel to move the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans. Features: The coupling nut used for connecting the bonnet and body allows fast make-up and break-out. Stem tip and bean adaptor are fabricated from special carbide alloys for corrosion and abrasion resistance. Indicator lens with scale marks allows the operator to know stemâ??s position and actual orifice area. Turn hand wheel counter-clockwise and the valve will open; turn hand wheel clockwise and the valve will close. Main technical datum Working Pressure: 2,000-20,000psi Nominal Dimension: 2-1/16 ~ 7-1/16 Working Temperature: P U Product Specification Levels: PSL1 ~ 4 Performance Requirement: PR1 ~ 2 material Class: AA ~ FF Working Medium: crude oil; natural gas Adjustable choke valve Valve needle and spool are made of tungsten carbide, with sufficient corrosion resistant, antieroding and wearable capability. The two kinds of adjustable choke, pintle type and the sleeve type could apply to wellheads& X-mas tree and choke manifold. Positive choke valve Material of choke bean is fabricated from ceramic and tungsten carbide, with sufficient corrosion resistant, anti-eroding and wearable capability. It adopts union bonnet so as to change choke quickly It has application in wellhead& X-mas tree and choke line. -
YG SERIES OF HOOK BLOCK Hook block complies with API 8C standard. Joining traveling block and hook together reduces overall length and can help satisfying the requirements of top drive operation. The hook block is equipped with the reliable safety devices on the main hook. The main parts are made of high strength alloy steels and are subjecte d to nondestructive testing. The sheave grooves have been intermediate frequency quenched, which can improve the hardness of the surface, the wearness, and the service life.
The drill collar is used between the drill pipe and the bit in the drill stem. It is used to put weight on the bit so that the bit can drill. Materials: Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available. Trepanning and Heat Treatment: Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface. Traceability: Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies. Rigid Inspection Procedures: We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar. Rolling: Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation. Phosphate-coated or Copper Plating: All connections are phosphate-coated or copper plated to improve resistance to corrosion. Slip Groove, Elevator Groove and Size: Huanjie offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines. Thread Protectors: Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.

Shale shaker is primary solid control equipment in the drilling fluid purification system.which is used to separate the large particle cuttings contained in the drilling fluid, and the treated smaller particle drilling fluid can be passed to the next stage of solid control equipment for further processing. Shale shaker is the prerequisite for ensuring the normal operation of the latter stages of solid control equipment. If the shale shaker can not work normally, the latter stages of solid control equipment will be overloaded with work,seriously affect the work effect, caused the performance of the drilling fluid to deteriorate, aggravate the wear of drilling pump cylinder liners, pistons, drill bits, water passage, etc and thereby increasing the pump repair time,it is easy to cause complicated underground conditions. Therefore, shale shaker are important for improving drilling fluid performance and reducing drilling costs.
Desander is an important part of the drilling fluid solid control equipment, mainly used to remove finer solid particles in the drilling fluid screened by the shale shaker. It using the principle of centrifugal sedimentation,the suspended particles can be separated and removed from the liquid after being accelerated by the centrifugal acceleration, so that the solid phase content in the drilling fluid can be effectively controlled, and obtain high-quality drilling fluid with excellent Technological properties with reasonable particle distribution, to meet drilling operations requirements.
Desilter is the third-stage solids control equipment in drilling operations and is mainly used to remove solid particles with a particle size of 12-47μm in the drilling fluid. The desilter has reliable technical performance, good treatment effect and the hydrocyclone has long service life and stable performance. It is suitable for use in all types of drilling rigs in the oil field. The inlet and outlet of the hydrocyclone are quick-connecting and very easy to replace and maintain.
Traveling Blocks Hooks is an indispensable lifting equipment for drilling rigs,it can be used to lift swivel or top drive equipment. this product can be usd with a variety of different rigs to adapt to the needs of oilfield drilling.
Mud tank is the necessary equipment and slurry processing equipment supporting the mud circulation system for storing the drilling mud.
Ignition Apparatus is an environmentally-friendly discharge torch that is exclusively produced by our company. It is suitable for ignition of long distances and air and toxic gas burning placesthat cannot be reached by humans.It is especially suitable for oil production(gas) overflow of gas or oil, naturral gas, and drilling operation in stationo gathering pipelines, and long-distance ignition of natural gas separated by liquid-gas separators during killing operations eliminate the unsafe factors of manual ignition. Avoid explosions that may occur when natural gas is mixed with air and H2S-containing gases that can harm humans and equipment.
1.Description: The Mechanical-hydraulic Drilling Jar is a jarring and stuck releasing tool. It integrates the up jar and down jar and can release the stuck accident occurring during drilling operation. The Drilling Jar is an ideal tool for directional well and deep well drilling. Operating Principle 1.Operating Principle Of Up Jar Lifting drilling tool,slip assembly which bear the acting of dish reed elastic force and slip locking force compels latch mechanism of slip clasp slip mandrel. While slip mandrel up run with mandrel to overcome slip locking force and damping action between hydraulic valve assembly and spindle extension, jar make drill stem accumulate energy, delay time. when mandrel up run to the state of release constraint,elastic potential energy accumulated in drill stem will convert to upward kinetic energy, generate up jar. If need sequence up jar, you need fed off drilling tool till relock latch mechanism, reduplication above process, generate sequence up jar. 2.Operating Principle Of Down Jar The loosen load of down jar lock can be transfer as per in demand .There are a certain ratio between up locking force and down locking force , and the ratio is adjustable. If down jar,fed off drilling tool until pressure reach to down locking force,jar should generate down jar force. If need to repeat jar,lifting drilling tool to anew securing position repeat above process.
