摘要
造成井壁失稳的原因是多方面的,主要影响可归结为力学因素、化学因素和工程技术因素。通过对2010年施工的钻井数据进行分析,对中原油田老区井壁稳定技术进行了研究。根据施工中遇到的问题,采取的措施,提出了对油田老区井壁稳定技术的一些想法,利于提高油田老区钻井的速度和质量。
The causes of borehole instability are mainly mechanical,chemical and engineering factors.By the analysis on drilling construction data of 2010,study was made on borehole wall stability technology in old area of Zhongyuan oilfield.Based on the problems in construction and the measures adopted,some suggestions were put forward for borehole wall stability in old area of Zhongyuan oilfield.
