Oil Well Drill Bit
The role of drilling in oilfield development is very important. It is estimated that drilling investment accounts for 35% to 40% of investment in certain oilfields.
The role of drilling in oilfield development is very important. It is estimated that drilling investment accounts for 35% to 40% of investment in certain oilfields. At present, the oil resources of various countries in the world are depleting. This requires drilling companies to carry out oil development more economically and efficiently. As the most important tool in drilling operations, the bit performance directly affects the quality, cost and efficiency of drilling operations. In the 1980s, people developed a Oil drill diameter professional composite drill bit (PDC drill bit) using artificial polycrystalline diamond as a cutting tooth, which can significantly improve the drilling efficiency and have a long service life. Wide range of applications. The PDC bit, downhole motor, while drilling test, and computer application in drilling are also called the four major drilling technologies in the 1980s . The advent of PDC bit was an outstanding achievement of the petroleum industry in the 1980s. It used to be an oil drilling engineering belt. A new technological revolution has come.
China began to introduce PDC bits since the early 1980s. After the 1990s, major oil fields began to use PDC bits and achieved good results. However, the quality of the composite sheet is still low, and the research on water conservancy design of the drill bit is scarce in China, so it needs to be researched and developed vigorously.
