本文综合应用了多学科的有关理论,对辽河断陷200多口井的资料进行对比分析,结合现代实验手段,研究坍塌层粘土矿物的成分、结构和理化性质。提出引起深部易塌层泥、页岩的粘上矿物是无序混杂的伊利石-蒙脱石和伊利石。并介绍了用扫描电镜观察泥浆处理剂对粘土矿物形态、结构的影响程度。
In this paper, the multidisciplinary theory has been applied in comprehensive analysis of the data of more than 200 wells in the Liaohe Fault Depression, combined with modern experimental methods to study the composition, structure and physical and chemical properties of clay minerals in collapsed layers. It is proposed that the adherent minerals that cause deep collapsing mud and shale are ill-defined mixed illite-smectite and illite. The effects of mud treatment agents on the morphology and structure of clay minerals were also observed by scanning electron microscopy.
