Composite Brige Plug For Oilfield

The non-rotating cementing plugs significantly reduce the drill out time, which leads to high efficient and cost saving. The cup design on top and bottom of both plugs provides a sure seal against the casing wall to prevent mixing of cement slurry and displacement fluid. The top plug seats into the bottom Plug and seals against it to lessen the possibility of additional cement slurry displacement, while also promoting good bonding at the bottom of the casing. No metal parts are used, so the plugs are competely PDC drillable.

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

1. API Casing float shoe and float collar Descriptions: Float collar and float shoe(guide shoe) are necessary conventional accessories for down-structure of casing string. float collat and float shoe is a heat-resisting, sealer and drillable tool. it's join easy and replace for guide shoe and casing shoe. it's used to protection casing and production casign, also used to deep well and ultra deep well. it classify ordinary type and self fill-up type according to way of drilling fluid get into. 2. API Casing float shoe and float collar Features: 1) All inner parts are made of easily drillable aluminum alloy 2) The device can be connected directly to same type casing 3) Reliable back-pressure leak proof structure, enable grout or slurry flow with less resistance 4) Valve seat and valve disk can effectively prevent grout from flowing back 5) Hardness of base material is equivalent to API Spec N-80 6) API spec.Q1 and ISO9000 certification

1.TheTubing Centralizer is designed to be run in the tubing string to keep the tubing centralized which may help in preventing premature wear of the casing and tubing. 2.The Tubing Centralizer can be directly above the pump for the vibration and harmonics dampening effects and other units can be installed further up the tubing string to provide the tubing and casing protection. 3.The Tubing Centralizer has full tubing ID specifications and is available for a large variety of casing sizes and tubing connections
