在含油气盆地中,松散的碎屑沉积物在沉降埋藏演化过程中一般都经历从压实,胶结到破裂的过程,这个过程势必对油气藏形成与分布有着重要影响,通过对前人该方面的研究成果的分析,认为目前砂岩、泥岩压实,岩石力学性质,岩石破裂(裂缝)等单一方面的研究方法和内容较为详细。而砂、泥沉积物沉积时是塑性的,在盆地演化过程中沉积物固结成岩有向弹性转化的过程,成岩后还会发生破裂。因此,要进一步加强沉积岩在沉降埋藏过程中力学性质的变化特征及对不同类型、不同结构岩石沉降埋藏过程中的力学性质演化特征的研究。
In petroliferous basins, unconsolidated clastic sediments generally undergo a process of compaction, cementation and fracture during the process of subsidence and burial. This process is bound to have an important impact on the formation and distribution of oil and gas reservoirs. Analysis of the research results, that the current sandstone, mudstone compaction, rock mechanical properties, rock rupture (cracks) and other aspects of the research methods and content in more detail. The sand and mud sediments are plastic when they are deposited. During the evolution of the basin, the sediments undergo consolidation and diagenetic transformation, and the fractures will occur after diagenesis. Therefore, to further enhance the sedimentary rock during the burial process of mechanical properties of the changing characteristics of different types and different structures of rock during the burial process of the evolution of the mechanical properties of the study.
