四川定向井水平井工艺技术的现状及发展方向

EXISTING STATE OF DRILLING TECHNIQUE AND TECHNOLOGY OF DIRECTIONAL AND HORIZONTAL WELLS IN SICHUAN AND THEIR DEVELOPMENT DIRECTION

文章回顾了“七五”以来四川石油管理局在定向井、水平井方面取得的技术进步及“八五”以来在几个方面应用和试验研究取得的成果。根据四川石油管理局该项技术的现状提出了在四川进一步发展定向井、水平井技术应解决的问题和进一步应用的范围。文章对四川石油管理局进一步利用定向井、水平井钻井技术实现挖潜增产具有一定的指导意义。

In this paper,the technical progress in drilling directional and horizontal wells since “the Seventh Five-Year Plan” and the achievements in applying,testing and researching this drilling technique since “the Eighth Five-Year Plan” obtained by Sichuan Petroleum Administration are reviewed.According to the present situation of this technique SPA masters,the problem which must be solved for further developing the drilling technique of directional and horizontal wells in Sichuan and the application scope of this technique are presented,which is of a certain guiding significance for attaining the goal of “tapping latent potentialities for increasing production” by further utilizing the drilling technique of directional and horizontal wells in Sichuan.
