C区块钻井液体系优化研究

摘要

国内外石油勘探开发领域,井壁失稳一直都是制约油气勘探开发进度的一大难点.主要针对C区块所钻遇的井壁失稳问题,从钻井液方面展开了研究,通过与邻井所用钻井液体系的室内性能研究对比,优选出了适合该油田钻进的BH-KSM钻井液体系,对于该区块后续钻井具有很好的指导意义,值得进一步的推广到该区块其他井位的开采.%In the industry of petroleum exploration and development at home and abroad,sidewall instability problem is a big difficulty that restricts the oil and gas exploration and development progress.In this article,the sidewall instability problem in C block was mainly researched from the aspect of drilling fluid,and the drilling fluid system was compared with that used in adjacent wells by the indoor performance study,at last the BH-KSM drilling fluid system suitable to this oil field was chosen.
