摘　　要：通过使用X射线衍射仪,铸体薄片,偏光显微镜来对油层岩石中粘土矿物,石英,长石,重矿物,碳酸盐进行定量分析,最后再利用接触角测定仪对接触角进行的测量.为了进一步分析描述各种岩石矿物组分对润湿性的影响,使用SPSS对岩石矿物进行分析,通过多元回归拟合出接触角的关系式,经验证拟合效果十分理想,可以作为今后现场对该油层的接触角预测的理论依据,更方便快捷地制订相应的提高采收率方案,从而节约了时间成本达到了节约开采成本的目的.By using X-ray diffraction,the casting thin sections,polarizing microscope to clay mineral in the reservoir rocks,quartz,feldspar,heavy minerals,carbonate in quantitative analysis,and finally using contact Angle measurement meter docking tentacles.In order to further analyze and describe the influence of various rock mineral components on wettability,meanwhile SPSS is used to analyze the rock mineral,and the relation formula of contact Angle is fitted through multiple regression,which proves that the fitting effect is very ideal and can be used as the theoretical basis for predicting the contact Angle of this oil layer in the future,so as to formulate the corresponding enhanced recovery plan more conveniently and quickly,thus saving time cost and achieving the purpose of saving mining cost.
