Roller Centralizer

Product description:

▲ Centralizers rollers are fixed on centralizer vanes such that the axis of rollers. The roller outer diameter is slightly larger than centralizer body outer dia. Rollers are capable enough to reduce considerable drag force due to low friction coefficient between well and centralizer. The small contact area of the rollers with the casing or borehole wall functions exceptionally well in under pressured conditions, where risk of differential sticking is high. High quality material provides excellent high temperature high-pressure performance and corrosion resistance, reducing the cost of replacement.

▲ Roller centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre casings.Roller Centralizers can also remove wellbore cake and improve mud replacement efficiency etc.Roller Centralizers provide superior wear resistance and have been proven to remain functional throughout the life of the well and can aid in casing/tubing retrieval.

▲Excellent corrosion resistance.

▲It will not fall off after long-term use in the hot and humid underground.

▲150 degrees high temperature resistance.

The casing can be divided into: casing, surface casing, technical casing and oil layer casing according to the usage.Petroleum casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion.Petroleum special pipe is mainly used for oil and gas well drilling and oil and gas transportation. It includes oil drilling pipe, oil casing, and oil suction pipe. The oil drill pipe is mainly used to connect the drill collar and drill bit and transmit drilling power. Petroleum casing is mainly used to support the well wall during the drilling process and after completion, so as to ensure the progress of the drilling process and the normal operation of the entire oil well after completion. The oil pumping pipe mainly transports the oil and gas at the bottom of the oil well to the surface.The oil casing is the lifeline for maintaining the operation of the oil well. Due to the different geological conditions and the complex downhole stress state, the combined effects of tensile, compressive, bending, and torsional stresses act on the pipe body, which puts forward higher requirements on the quality of the casing itself.


Float equipment Product description：

▲Sizes ranging from 5-1/2" to 20"

▲Automatically running into the hole

▲Conventional float equipment

▲PDC Drillable

▲API and premium thread

Specializing in the production of all kinds of floating hoop and floating shoes, the products have high temperature resistance, good sealing and drillability, and easy connection, so they can replace lead shoes and casing shoes. Floating shoes or hoops can be used not only for general technical casing and oil layer casing, but also for deep wells.


Cementing plugs


▲When injecting cement, isolate the cement slurry and mud to prevent the penetration of mud into the cement slurry and affect the cementing quality.

▲The cementing plug series are divided into ordinary cementing plugs, upper and lower rubber plugs for double cementing cementing, and upper, middle and lower rubber plugs for dual-stage cementing.

▲The standard cement rubber plug is suitable for all kinds of floating hoops and floating shoes; the anti-rotation cement rubber plug is suitable for anti-transformation floating hoops and floating shoes.▲The top and bottom plugs are designed with two-stage seals and scraping wings.

▲The anti-rotation rubber plug is designed with anti-rotation mechanism,.

▲which can greatly increase the drilling speed.

▲PDC bit or roller bit can be drilled.


Diamond Wire Drawing Die


▲During the processing, the products produced by ultra-high temperature and ultra-high pressure are sintered together with a strong grain-to-grain bond in the presence of several metal catalysts (containing cobalt). These PCD products not only have high wear resistance, hardness and thermal conductivity, but also have high mechanical strength and toughness. They are suitable for copper, aluminum, nickel and other non-ferrous metal wires and high-speed tensile alloy wires of stainless steel and other metal materials.

▲Diamond drawing die blanks include two series: RS series and TRS series. RS series includes hexagonal self-supporting PCD mold blank shape (RSH) and round (RSR) various sizes. These blanks are suitable for all types of wire drawing applications, especially where cost reductions are required. The TRS series includes various sizes of round tungsten carbide supported PCD mold blanks. These products have a polycrystalline diamond core integrated with a tungsten carbide-supported ring, thereby increasing the strength of the mold blank. These features make the product have a stronger ability to withstand high-strength cable.

Stage cementing collars


▲Divided into hydraulic type and mechanical type.

▲The hydraulic type solves the challenge of cementing at any angle. It is specially used for primary cementing in the case of deep vertical or high-deflection horizontal wells. The total hydrostatic pressure in the weak formation is reduced to prevent lost circulation during cementing. Clear surface indication of opening and closing pressure provides safer and more efficient operation. The opening pressure of the stage ring can be adjusted at the rig site to meet the requirements of the well, thereby providing operational flexibility.

▲Mechanical grade collars allow cementing of casing strings in two stages. These collars set the standard for reliability, cost effectiveness and ease of use with outstanding built-in functionality and quality. The compact, simple design minimizes the number of moving parts and makes the tool easier to operate. The clear opening and closing instructions of the collar on the ground can be adapted to the hydraulic conditions of the oil well, thus achieving safer and more effective operation. The inner sleeve improves reliability and prevents premature restrictions due to the application of pressure. It can reduce the total pump pressure in long casing strings.


Drill bit


▲ Matrix body PDC bitThe deep blade and short parabolic design ensure the best bottom hole flow pattern and anti-balling.Optimize the cutting structure, place high-quality cutters in different positions, improve wear resistance and drill offense.Anti-rotation design improves ROP and enhances drilling stability.Made of high-quality tungsten carbide matrix powder to ensure the corrosion resistance of the drill bit.

▲ TricyclicSuitable for soft rock formations with low compressive strength and high drillability.Surface welding of tungsten carbide particles can be widely used along the dovetail shape and extends to the leading edge of the drill leg to provide additional protection in high-speed, directional or abrasive applications. The dovetail-shaped tungsten carbide compact can protect the legs and body In abrasive structures and in deviated or horizontal wells.More tungsten carbide blades were placed in the gauge to reduce wear in the abrasive layer. It can protect the instrument and increase the stability and life of the drill bit.The optimized flushing system, including three combined nozzles, can balance fluid flow, effectively clean the bottom hole area and prevent balling.
