摘要
裂缝作为油气运移的主要通道和良好的储集空间,在盆地沉降和抬升过程中具有不同的形成机制和特点.前人在这方面已做了大量工作.对盆地沉降抬升过程中与垂向载荷增加有关的裂缝、与垂向载荷减少有关的裂缝、与异常压力有关的裂缝、与褶皱有关的裂缝和与断裂有关的裂缝的形成特点进行了分析,并指出其存在的问题,认为在以下两方面的研究还需要加强:盆地内裂缝的产状及其空间组合特征的研究;盆地内裂缝的空间展布.
Previous study has suggested that cracks in reservoirs is good channels and space for oil preser- vation,various cracks can formed during the sedimentation and uplift stage of the oil basin.In this paper, the character of crack related with increased vertical load,decreased vertical load,abnormal pressure,fold, and fault in the process of basin uplift are discussed.As mentioned above,we proposed that the two problem are still need be reinfoeced study:form and assembled character of the cracks in sedimentati...
