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.
Plug Valves are used to control flow opena and close. valve bodies are die-forged from premium alloy steel and heat treated to ensure the strength. plugs and seal segments are machined from heat treated alloy steel with special surface treatment to ensure reliable sealing capacity. Compact structure, easy operation and maintenance. Union connections on both ends. Available with manual, handwheel and hydraulic actuators with limiter switches. Valves can be serviced without removing from the line. Plug valves for standard service range are available in 1 " to 4 " bore sizes and 6,000psi to 20,000psi rated pressure. We has also developed plug valves for H2S service in accordance with NACE MR0175 criteria with 1 " to 4 " bore sizes and 10,000psi to 15,000psi rated pressure. JASON provides a customized design to meet each customers unique requirements. Recommended service: Fracturing, cementing,acidizing and testing lines;

Float shoes contain a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing. Float collars are placed one to three joints above the guide shoe or float shoe. They provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement. The space between the float shoe and the float collar provides a containment area to entrap the likely-contaminated fluids from the wiping action of the top cementing plug, securing the contaminated fluid away from the shoe where a strong cement bond is of primary importance. Float collars include a backpressure valve and serve basically the same function as the float shoe. Features: The Aluminum Alloys used in this product are PDC Drillable. Available in 5 1/2â?? to 20â?? sizes. Customized sizes are also available. Applications :In all applications ranging from close tolerance liners to full casing strings. Standard float shoe is provided with round cement nose to deflect offledges or obstructions. Customizable options including nose types, ports/jets, and ball deflector. Can be supplied either in Single Valve or in Double valve.

Detailed Images The Hammer Union can be used for cementing trucks, all kinds of manifolds and other high pressure equipment, and pipes. It is an important part for transporting oil. Water, fracturing fluid and mixed fluid. These products are all made of high quality steel by forging and finishing cut. They have good. Mechanical performance and sealing property. Especially they can operate under the bad weather condition. They can be assembled fixed easily and conveniently. Main technical parameter model number collecting norm working pressure, structural length drift diameter. The product adopts some end connections of pipeline thread, tubing thread, butt-weld.
Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard. Sucker rod has various types including the common sucker rod, hollow sucker rod and FRP sucker rod. Commonly we use the sucker rod coupling to connect the sucker rod. The sucker rod also has various specs to fit different environments and applications
The torque anchor is a special anchor for PC pump. With good centering performance, the anchor is seated in the well without lifting and down. It has easy operation and good stability. The anchorâ??s blocks are anchored in the inner wall of the casing at same time with same pressure pressing on the casing from three points to avoid damage the casing. To avoid the tubing thread being tripping, the anchor has anchor force as greater as reverse torque. The Torque â?¥ 5000N â?¢m. Alloy material of the anchor is suit for corrosion oil and gas well. The anchor has very good anchoring performance, easy operation, good centering performance. The torque anchors are mainly exported to Peru, Venezuela, Kazakhstan, Russia, Sudan, Chad, and Algeria.
