采卤对接井钻井技术的研究

Study on Directional Drilling Technique for subsurface Intersected Brine Development Wells

摘要:

为了改变岩盐矿单井水溶采卤和其它采卤方法的缺点，采用螺杆钻受控定向钻探技术，使两口中曲率半径大斜度定向井在盐层中交叉对接，实现对接井水溶采卤。本文，着重介绍对接井施工新技术及对接井试验研究结果。

Abstract:

In order to overcome the disadvantages of brine development by aqui-soluble through a single well in the rock salt,the controlled directional drilling down -hole motor is employed to make a pair of me-dium-radius of curvature ,highly inclined directional wells intersected with each other in the subsurface salt forma-tion,realizing brine developed by the intersected wells .Therefore ,description :Emphasized on the new drilling tech-nique,testing and study results of the intersected wells.
