Since the 1990s, the well-drilling technology has begun to develop rapidly abroad. At present, the number of well-drilling equipment equipped globally has exceeded 15,000, and will exceed 20,000 in 2011, and it is still increasing. In many developed countries, well drilling has become a routine drilling technique.

Since the 1990s, the well-drilling technology has begun to develop rapidly abroad. At present, the number of well-drilling equipment equipped globally has exceeded 15,000, and will exceed 20,000 in 2011, and it is still increasing. In many developed countries, well drilling has become a routine drilling technique. For example, drilling wells in the United States and Canada account for about one-fifth of the total wells in the country. Well drilling technology has many advantages. For example, it can effectively solve the problem of traditional well-draining oil and gas layers, and greatly reduce the damage caused by drilling wells to the formation. It fundamentally solves the problem of lost circulation and effectively discovers various hidden oil and gas layers, thereby exploiting oil and gas fields that cannot be found by traditional methods, equipment and processes. Well drilling technology can also greatly improve oil and gas production efficiency. For example, first, in terms of output, according to the statistics of some foreign companies, the well drilling technology can increase the horizontal well production by about 10 times compared with the conventional method of drilling horizontal wells; Second, in terms of speed, the speed of drilling wells has increased by more than 10 times compared with conventional wells, and some even exceeds about 20 times.

At present, the number of well-drilling equipment equipped globally has exceeded 15,000, and will exceed 20,000 in 2011, and it is still increasing. In many developed countries, well drilling has become a conventional well-drilling technique. For example, drilling wells in the United States and Canada have accounted for one-fifth of the total wells in the country. Currently, all oil and gas fields in China are using well-drilling technology. The number of well drilling machines is increasing rapidly, and it is expected to increase from 0.5% of the total number of wells drilled in the country to 3% to 5% within five years. With the large number of drilling teams in China going overseas and using new technologies extensively, the number of wells that our country has overseas will also increase rapidly. In China's petroleum industry, well drilling technology has become a mature and systematic technology. In this technical field, various oilfields in China have successfully tried or applied the main technical routes such as foam drilling, air drilling, nitrogen drilling, tail gas drilling, natural gas drilling, aeration drilling, and atomization drilling. What is particularly gratifying is that China has not only researched, developed and improved a large number of well drilling technology solutions, but also designed and manufactured a large number of well drilling equipment, gradually realized the localization of major equipment, and gradually began to export technology, technology and equipment overseas.

At present, the number of well-drilling equipment equipped globally has exceeded 15,000, and will exceed 20,000 in 2011, and it is still increasing. In many developed countries, drilling wells has become a routine drilling technology. For example, drilling wells in the United States and Canada have accounted for 1/5 of the total domestic drilling wells. The drilling machine technology has been used in various technical routes. Forming a systematic, complete, stable and effective equipment and process technology system, such as gas well drilling, atomizing well drilling, foam drilling, aeration drilling, fresh water or brine drilling fluid drilling, conventional drilling fluid drilling and Mud caps and other wells. From the patent literature, foreign well drilling technology is mainly concentrated in well control, drilling fluid, program design, special tools and so on. However, as the drilling technology continues to update, its patent deployment space continues to expand. In the special industry of oil and gas drilling and mining, the situation of monopolizing international technical standards by the so-called basic patents has not appeared, and it is difficult to appear in the future.
