在岩盐钻井中首先利用自然井斜规律,先后成功地钻成我国两组小井斜双筒定向井。这项岩盐钻井技术的革新不是采用传统的双筒定向井方法,而是应用了优选法和统筹法,克服了缺乏设备器材的困难条件,从而在长山矿区进行的工业性试验中获得成功。该项试验为国家节约了农地和大量资金,曾获得省、市和局的奖励。本文介绍去年底至今年初先后钻成的两组岩盐小井斜双筒定向井的设计与实践。
In the rock salt drilling, the natural inclination of the well is first used to successfully drill into two groups of small inclined double-directional wells in our country. This rock salt drilling technology innovation instead of the traditional binocular directional well method, but the use of optimization and co-ordination method to overcome the lack of equipment and equipment difficult conditions, which carried out in Changshan industrial test success. The experiment saved the country farmland and large amount of funds, and won provincial, municipal and bureau rewards. This paper introduces the design and practice of two sets of rock salt Slim Slant Binocular Directional Drilling completed from the end of last year to the beginning of this year.
