近十年来国外的减速涡轮钻具钻井技术发展迅猛,井下钻具的发展已得到广泛的重视,被视为本世纪最有发展前途的钻井技术。而最先采用减速涡轮钻井技术的是苏联。下面介绍各国的井下动力钻具的发展和使用情况。叙述国内外减速涡轮钻具的发展以及为了降低钻井成本,增加钻井公司参与国内外竞争的能力,根据国内外最新钻井技术信息,缩短涡轮钻具长度,发展新型低转速、低压降、高扭矩减速涡轮钻具,配合牙轮钻头和PDC钻头钻进,降低综合钻井成本,增加钻井公司的技术储备和对外投资能力。
In recent ten years, the technology of slowdown turbine drilling has been developed rapidly in foreign countries. The development of underground drilling has received extensive attention. It is regarded as the most promising drilling technology in this century. The first to use slowdown turbine drilling technology is the Soviet Union. The following describes the development and use of downhole power tools in various countries. Describe the development of gear reducer at home and abroad, and in order to reduce drilling costs and increase the drilling company’s ability to compete at home and abroad, according to the latest drilling technology information at home and abroad, shorten the length of the turbine drill, the development of new low speed, low pressure drop, high torque deceleration Turbine drills, with roller cone bits and PDC bits, reduce integrated drilling costs and increase drilling company technical reserves and foreign investment.
