吐哈第一口水平井红南210井固井技术实践

THE FIELD PRACTICE OF CEMENTING TECHNIQUE USED IN THE FIRST HORIZONTAL WELL HONG NAN No.210

红南210井是吐哈油田在西部红南构造上钻成的第一口水平井,固井施工中成功地应用了固井实施监测技术软件和套管柱设计软件,并使用了压差式分级箍、管外封隔器、割缝筛管等固井附件及內管注水泥工具,自行设计了水泥浆配方。本文介绍了该井的设计思路及施工情况,并总结了吐哈油田水平井的固井经验。

Hongnan No. 210 well is the first horizontal well drilled at the Hongnan structure in the westpart of Tuha Oil Field. The realtime monitoring software and casing string disign software had been used successfully in the cementing practice and pressure differential grading coupling, outside casing packer and slotted liner etc. cementing accessaries and inside casing cement - injection tools had been used and the prescription of cement slurry had been designed. This paper describes the well's design philosophy and performance of the cementing practice and makes a conclusion of the cementing practice for the horizontal well.
