Starting with the most basic research, this new type of bearing has been completely redesigned to provide excellent performance and optimum reliability. The drills with RockForce bearings also incorporate several of the company's proprietary technologies, including Mud Pick hydraulic construction, Su-perTuff alloy teeth, Match Fit solid teeth technology and Ventrite pressure compensation systems.
Rock Force bearing technology is available for both steel and insert bits. The company's steel-toothed drills range in size from 33/4 to 63/4 inches, and the insert bit sizes range from 33/4 to 121/4 inches. This bearing technology was first put on the market in 2005, at the time to solve the problem of the urgent need to improve the performance of the drill bearing in directional and horizontal well motor drilling. Through a comprehensive study of the formation lithology, directional drilling requirements and previous drilling records of the drill block, the company produced several different structures that reflected this new bearing technology and conducted field tests. After the initial test was successful, it was trial-produced. More drill bits are used for large-scale field trials.
RockForce bearing technology includes the following features: high energy cone fastening, and low contact stress of the packaged ball track structure, which helps to improve bearing load capacity and reliability; tolerance and clearance control of this bearing More precise, this can reduce axial wheel sloshing, extend seal life, reduce thermal cracking and fatigue damage, and make bearing performance more stable. This bearing has a precision-machined silver-plated surface on the sliding surface. The use of high-quality solid lubricants reduces friction and extends bearing life; the Rock Force bearing's seal structure is optimized for bearing size, which helps to extend bearing life and ensure consistent performance; the bearing also features an advanced lubrication system. The specially formulated special-purpose grease that guarantees bearing performance and prolongs the life is also equipped with a Ventrite pressure compensation system that reduces seal stress and grease contamination, making the bearing more durable.
After extensive trials of 77/8 and 83/4 inch drill bits in five blocks, the company finally imported 365 drilling records using Rock Force bearing technology and 936 adjacent wells. In the Bit Trak database. By comparison, the reliability of the two sizes of Rock Force drill bearings is superior to that of all other adjacent wells. Subsequent tests in Canada, Oklahoma, and the Middle East have also confirmed that drills using Rock Force bearing technology have excellent drilling performance in both small borehole drilling and large 121/4 inch bit drilling.
New drill bearings meet complex drilling challenges
As the demand for drilling technology in vertical and directional wells has become more complex, the torque and energy output of power drills has almost reached 10 times that of the past, and the reliability of drill bearings has become more critical than ever. At present, the major drill manufacturers in the world pay great attention to the research and development of bit bearing technology. According to the US "World Petroleum" magazine, the Ryder Haikarloger's Rock Force roller bit bearing technology is to cope with today's complex drilling technology. Specially developed for challenges.
