油基钻井液应用中存在的问题分析及对策

Problem analysis and countermeasure of the application of oil-base drilling fluid

胜利油田罗家区块和乔庄地区沙三段油、泥页岩裂缝发育,在该区块钻井具有一定的风险性,使用油基钻井液可以很好地解决此问题。目前,油基钻井液已在多口井进行了应用。在对油基钻井液性能进行介绍的同时,对在渤页平1井、渤页平2井及梁页1井的现场应用中存在的一些问题进行了归纳分析和探讨,并提出了相应的对策。

Drilling in Luojia block and Qiaozhuang area of Shengli Oilfiled has certain risk because of the crack development of oil and mud shale. Using oil-base drilling fluid could solve the problem well. At present, oil-base drilling fluid has been applied in several wells in these regions. In this pa- per, the applications of oil-base drilling fluid are summarized. Some problems existing in field applica- tion are concluded and analyzed, and some countermeasures are proposed.
