九龙山构造致密砾岩储层裂缝发育的控制因素
Control factors for fracture development in tight conglomerate reservoir of Jiulongshan structure
摘要
Abstract
Based on the data of outcrops, cores, image logs and thin sections, the distribution characteristics and controlling factors of fractures in tight conglomerate reservoirs were discussed. The results show that there are three types of fractures which include trans-gravel fractures, gravel-edge fractures and intra-gravel fractures in the tight conglomerate reservoirs. A-mong them, trans-gravel fractures are dominant. The development degree of these fractures is controlled by the gravel composition , gravel size, contact relationship between gravels, interstitial material composition and structural location. The fracture development degree in the quartz sandstone gravels is better than that of the chert gravels. The development degree becomes better with the increase of gravel size, contact area and interstitial material, while the content of clay matrix is adverse to the fracture development degree. The favorable areas for fracture development are the high part of structures and the fault areas, which are the favorable areas for natural gas accumulation.关键词
