摘要
在碳酸盐岩储层中,裂缝不仅是油气藏运移的通道,还可以为油气藏提供储集空间,是影响碳酸盐岩储层含油气性的关键因素。羌塘盆地碳酸盐岩储层在形成过程中经历了多期构造活动和成岩作用,形成了多期天然裂缝,这些裂缝是影响羌塘盆地碳酸盐岩储层含油气差异性的重要因素。因此,对天然裂缝形成期次进行研究对于羌塘盆地碳酸盐岩储层油气藏高效开发具有重要意义。
In carbonate reservoirs,fractures are not only channels for oil and gas migration,but also provide storage space for oil and gas reservoirs,which is a key factor affecting the oil and gas bearing capacity of carbonate reservoirs.The carbonate reservoirs in the Qiangtang Basin have undergone multiple periods of tectonic activity and diagenesis during their formation,resulting in the formation of multiple natural fractures.These fractures are important factors affecting the oil and gas heterogeneity of the carbonate reservoirs in the Qiangtang Basin.Therefore,studying the formation stages of natural fractures is of great significance for the efficient development of carbonate reservoirs in the Qiangtang Basin.
