China Scoton Oilfield Equipment Co., Ltd. products

Fixed diameter hole opener is used for expanding drill areal large hole in terrestrial oil field and oceanic oil field. It is used to reaming the well bore what has been drilled by the big cone’s bit or used to connecting it to the drill bit and finish well drilling and reaming of hole.

This high-performance dissolvable frac plug is rated to 10,000 psi for zonal isolation during wellbore stimulation and combines industry-leading frac plug designs with the most advanced dissolvable metal and degradable rubber materials. The large bore ID allows operators to produce through the plug while it remains in the wellbore and begins the dissolution process immediately following fracturing. The fully dissolvable frac plug not only helps reduce the cost and time of plug mill-out operations, but it also helps eliminate the risk associated with coiled tubing. Fewer operational steps are required to get a well onto production, reducing rig time as well as personnel and equipment on the rig site, and decreasing the potential for safety and wellbore issues. Since no intervention is required to clean the wellbore after the frac, production may be brought on sooner to improve the net present value of the asset.

Drill collar is made of rolled or forged AISI 4145H chrome molybdenum alloy steel for effective control of chemical composition and trace element content. Drill collar is at the lowest part of the drill string and is the main component of the lower drill assembly. Its main feature is the wall thickness (usually 38 ~ 53mm, equivalent to the drill pipe wall thickness of 4 to 6 times), with greater gravity and stiffness.
