在多年的石油开发实践中,人们一直在探秘高效开发油气藏的有效途径。于是,定向井、水平井、分支井等复杂结构井及旋转导向、地质导向等先进钻井技术相继得到开发应用,并在生产实践中发挥了巨大的作用,为进一步丰富油气藏开发手段、提高油气藏开发利用率和采收率创造了条件。 In many years of oil development practice, people have been exploring efficient ways to develop oil and gas reservoirs. As a result, advanced well drilling technologies such as directional wells, horizontal wells, branch wells and other complex structural wells as well as rotary steering and geosteering have been developed and applied one after another, and have played a huge role in production practice. In order to further enrich the means of reservoir development and increase oil and gas Tibetan development and utilization of oil recovery and create the conditions.
