    摘要:

    摘要:为了研究伊通地区易坍塌地层的坍塌机理和防塌对策,根据目前国内外井壁稳定研究状况,本文着重进行了进行岩芯的特征观察,岩石矿物成分分析,泥页岩理化性能测试。在泥页岩理化性能的测定中,主要选择了阳离子交换容量,比吸水量,泥页岩回收率和泥页岩膨胀率的测定。根据测定结果,进行坍塌机理的分析,进而针对坍塌机理提出防塌对策。

    Abstract: In order to study sloughing mechanism and anti-sloughing measures of collapsible strata in Yitong area, according to research status of the current domestic and international sidewall stability, this paper focusing on the appearance characteristics of the core, rock mineral composition analysis, test of the shale physics and chemistry properties. When testing shale physics and chemistry properties, we mainly chose to test CEC, specific water absorption, shale recoveries and shale inflation rate. According to the test results, we analysed sloughing mechanism, and then proposed anti-sloughing measures.
