对待钻地层的岩石力学特性研究是石油工程中一个十分重要的部分,它不仅增加石油工作者对储层岩性的认识,还能为钻头选型、预测钻速、选择合理的压裂施工方案等提供依据,而海拉尔盆地贝尔凹陷布达特群储层为古潜山油藏,岩性较复杂,属双孔隙介质储层,本文通过岩心描述、岩石薄片和裂缝测井分析等技术,对该区的储层岩石力学特征、储层裂缝特征、油藏地应力特征、矿物学特征等进行了研究,对布达特群储层的开发具有一定的指导意义。
The study of rock mechanics characteristics of the drilled formation is a very important part of petroleum engineering. It not only increases the understanding of reservoir lithology for oil workers, but also can be used to select the bit, predict the drilling rate, and select a reasonable fracturing construction scheme Etc. The Budate reservoir in Beier Sag of Hailaer Basin is an ancient buried hill reservoir with relatively complex lithology. It belongs to a dual-porosity reservoir. Through the techniques of core description, rock slice and fracture logging analysis, The reservoir rock mechanics characteristics, reservoir fracture characteristics, reservoir stress characteristics and mineralogical characteristics are studied in this area, which is of guiding significance to the development of the Budat reservoir.
