应用物探技术方法,结合地质、物探、测井及录井等资料分析塔河油田四区断层对裂缝的控制作用,断层、裂缝与岩溶之间的关系,揭示碳酸盐岩裂缝与岩溶的发育规律,从而分析缝洞对油气分布的影响。研究表明:断裂系统对岩溶发育具有控制作用,促进岩溶的发育;裂缝与岩溶之间的关系始终是相辅相成、相互促进的关系。断裂带是裂缝与岩溶发育的有利带,是油气分布的有利区。
Based on the geophysical, geophysical, logging and well logging data, the relationship between faults in the four areas of the Tahe oilfield, the faults, fractures and karst, and the development of carbonate fractures and karsts are analyzed. Regularity, thus analyzing the influence of fracture cavern on oil and gas distribution. The results show that the fracture system can control the development of karst and promote the development of karst. The relationship between the fracture and karst is always complementary and mutually reinforcing. The fault zone is a favorable zone for the development of fractures and karstification and a favorable area for oil and gas distribution.
