Bridge Plug

Overview Products Description The Composite Bridge Plug is made from composite material and easy to drill out. It is mainly composed of mandrel, rubber, slips, cones, protection bowls, release/start pins, lower sub and so on. The composite bridge plug is mainly used for provisional plugging in oil and gas well, and fracturing construction Working principle The opposite power produced by setting tool (wire line or transmitting hydraulic pressure in oil tube) acts on the lower sub, shears the starting dowels and exerts compressive force on rubber through cone. Inside the tension range slips dehisce and inlay the in wall of the casing, rubber expand to the in wall of the casing and seal up it, finish setting. When the tension rises to the shear rating, the starting dowels be sheared and the setting tool separates from the bridge plug, finish releasing. After taking out the setting tool, the frac ball that be put into the well will work hermetically with the head face of the mandrel. The plug can be quickly drilled out under the necessity of the after steps Drilling out Recommend the use of special milling tools. Recommend rotation rate: 60~150rpm, bit weight: 5~15kN, viscosity of drilling plug fluid:15~30mPas and minimum cyclic velocity: 36.6m/min, to make sure the debris circulates out. After the preparation is done, start the screw drill and drill slowly into the bridge plug. Ensure continuous drilling speed by applying drilling pressure. The torque added to the drilling tool should not be greater than the recommended value. Excessive drilling pressure increases the friction resistance of the pipe string and results in large pieces of debris which must be salvaged separately.

Overview Product Information: 1. Application It is a important well completion tool. It's mainly used in complex oil, gas or water well completion engineering to realize downhole packing or plugging, improve well cementation and well completion. It is used for staged packing of open holes for further operation. The pressure opens the packer's rubber for setting. It mainly consists of central pipe, rubber, open/close valve. The open valve is activated by enough pressure to demanding value, and then set the packer. More pressure shall activate the close valve to close the packer. 2. Structure and work principle It adopts expanding steel frame rubber as sealing element, it is a permanent external casing packer that setting controlled by Combination valves. It is mainly composed of valve joint, rubber assembly,central tube, pup joint, coupling and so on. During construction, when rubber plug go through valve joint, rod in the sealing inlet hole break off to open the inlet hole. When the rubber plug run to spoiler, start built pressure in casing. Liquid run into open valve from valve joint, when the pressure reached to the design, pin on open valve was cut to realize open the open valve. Liquid go through check valve and pressure limiting valve, run into the cavity between central tube and rubber. Then packer expansion and close to well wall to from seal. When expansion cavity pressure reached to the design of pressure limiting valve pin, pin break off, pressure limiting valve take movement to close the inlet hole in order to realize sealing safety. Wellhead release pressure to 0, open valve self-locking to realize permanently closed. Downhole pressure operation has no influence of packer. In the special pipe string precess, it can run inner pipe tools to set packer in order to realize special well completion(eg: well completion by packer or packer sieve tube). 3. Characteristics 1) Simple operation, no need to change the original operating craft. 2) Better adaptability, being applicable to oil/water well under various different condition. 3) Valve system can effectively protect and exactly control the tools to take setting safely. 4) Big expansion coefficient, small diameter rubber barrel can seal the big diameter well. When70mm packer is used in 7''casing, breakdown pressure can reach 28Mpa. 5) Small residual deformation. 6) It has high temperature resistant level, and can bear big differential pressure, with small residual deformation. 7) Long sealing section, reliable setting.

Brief description: The Gas Separator separates free gas from fluid prior to entering pumps and helps avoid costly pump damage. The Gas Separator was designed to provide a method of allowing gas to separate out of the solution and migrate up the annulus, preventing gas locking of the down-hole pump. They use centrifugal forces to separate the gas from the produced liquids, before they enter the pump. Liquids will be carried through into the pump suction while the separated gases are forced to migrate up the annulus. Using the tool allows gas-free production fluids to be carried into the pump station while the separated gases are forced to migrate up the annulus. The Beam Gas Down-Hole Separator pump increases efficiency and production. Features: 1,Gas separation 2,Production increase 3,Prevents gas locking 4,Increases pump rate/ Pump efficiency and pump rate will be increased
