摘要
借鉴四川局对二叠系阳新统断层裂缝型气藏的研究成果 ,结合贵州赤水地区勘探情况 ,分析了断层与地震异常的关系 ,讨论了旺隆构造东断块高点及高点之南断层。指出了赤水地区地震异常块基本沿断层走向且位于上盘分布 ,表明与断层裂缝有密切关系 ;认为旺隆构造北北西向断层对东断块高点之南的油气影响不大 ,之南的两条逆断层形成的断垒部分对勘探天然气较高点有利 。
Based on the study of gas pool of fault-fissure type in Yangxin series of Permian carried by Sichuan bureau, compared with the exploration situation in Chishui region of Guizhou, the authors analyze the relation between fault and seismic abnormality, and discuss the culmination of eastern fault blocks in Wanglong structure and the southern fault of the culmination. It has been shown that the seismic abnormality blocks are generally distributed in upper wall along the trend of fault, and the results appear the distributed relation is strong with fault fissure. It is thought the influence of NNW fault in Wanglong structure is less to the oil gas in the southern culmination of east block, the fault rampart formed by two reverse faults in the southern culmination is advantageous to explore the culmination of the natural gas. Three initially proven well places are presented.
