塔里木盆地北缘碳酸盐岩野外构造裂缝发育规律研究
Research on the Carbonate Rocks Fractures in the Northern Margin of Tarim Basin
摘要
Abstract
More and more attentions have been paid to marine carbonate oil and gas exploration. Although carbonate rocks are normally dense, a variety of geological processes can make the carbonate rocks to become good oil and gas reservoirs. By analyzing fracture features of the carbonate rocks in the northern margin of Tarim Basin, we pointed out that lithology, stratum thickness, weathering crust, fluid transformation, and tectonics played an important role in fracture development. Coarse crystal dolomites are prone to developing more fractures than do fine crystal dolomite;More fractures are produced in thinner strata than thicker ones;More fractures are formed at the top of the weathering crust than at its bottom;The presence of fluid is conductive to fracture development while the effectiveness of the fracture development is reduced after the fracture is being filled;The greater curvature of the folds, the more fractures;Also, more fractures will occur near the fault and decrease exponentially with distance away from the fault.关键词
