Zhang Dawei, director of Wuhan Drilling and Manufacturing Co., Ltd., told the reporter that the company used its own research and development technology to tailor the 8.5-inch KS1952SSN diamond drill bit for the TK941H well in Tarim Oilfield. The drilling speed is only 9 meters, reaching 18.6 meters per hour.
When the global financial crisis spread, the demand for oil drill bits declined overall, and the market competition further intensified, Jiang Diamond launched this product with independent intellectual property rights, which undoubtedly set the banner of national brands in the world high-end market. This is the result of Jianghan Oilfield's overall development of the scientific outlook on development, and actively promotes the development of stable oil and gas.
As of March 11, six diamond drill bits sold to Iran and Jianghan oilfields were drilled in complex formations such as Jinghe, Qianyi, Qianji, Qiansan, Qiansi, Jingsha and Xingou. Only the drill bit was created in 7 wells and 7 times, the total footage was 688.93 meters, and the average mechanical drilling rate was 17.89 meters per hour.
Oil drill bits are mainly cones and diamond bits. Compared with the roller cone drill bit, the diamond drill bit has a simple structure, high mechanical drilling speed, long pure drilling time and high safety. It can be used together with downhole power drills, featuring less downhole accidents and good well quality. With the acceleration of marine gas exploration and the increasing complexity of continental formations, complex drilling processes such as deep wells, directional drilling, and underbalanced drilling are widely used. The formation and drilling methods are complex and diverse, and the requirements for drill bits are getting higher and higher. Under such circumstances, each oil and gas field still pursues high mechanical drilling speed to improve the efficiency of exploration and development, which also provides a living environment and development space for the diamond drill bit to attack the high-end market.
At the same time that Jiang Diamond has captured high-end products with high-end products, the international oil drill industry giants Hughes and Smith have successively entered the field of marine and terrestrial oil and gas exploration in China, occupying the high-end market of diamond bits. However, the imported diamond drill bit is expensive, and the 12.25-inch drill bit reaches 88,000 US dollars/only. The market urgently needs a diamond drill bit with higher cost performance, which provides a good opportunity for Jiang Diamond.
Jiang Diamond Co., Ltd. continuously innovates on the basis of digesting imported technology. The diamond drill bit independently developed has better formation adaptability, better work stability, effectively prolongs the service life of the drill bit and improves the mechanical drilling speed of the drill bit. At present, Jiang Diamond Co., Ltd. has 18 distribution and service stations in various oilfields in China. The marketing personnel are stationed for a long time. The design and sales engineers carry out personalized technical services on the oilfield site, which can be tailored according to the target well section. The ground selection design provides users with the full life cycle of the product.
