摘要

构造演化分析认为,温江构造为古今叠合型构造,紧邻上三叠统生气中心。西侧发育作为油气运移通道的彭县断层,有利于天然气运聚成藏。化探和钻井揭示,深层的天然气已经运移到浅层,并聚集成藏。蓬莱镇组、遂宁组为三角洲平原亚相沉积,蓬莱镇组的“低频、强振幅”地震异常比较发育,反映储集砂体发育。用容积法计算,浅中层圈闭资源量达401×108m3,表明温江构造浅中层是近期勘探的有利目标。
Tectonic evolution analysis indicates that Wenjiang Structure is a palaeo-present-congruent structure and very close to Upper Triassic gas-generating center. As a petroleum migration channel, the Pengxian Fault, developed at west of the structure, is favorable for gas accumulation and forming a reservoir. Geochemical exploration and drilling show that deep gas has migrated into shallow formations to accumulate and form the reservoir. Penglaizhen and Suining formations deposit at deltaic-plain facies. For the former, abnormal seismic is almost characterized by low frequency and strong amplitude, reflecting a well-developed sandbody. The resource of shallow and middle traps reaches to 401×10~8m~3 by the volume method, which suggests the shallow- and middle-formations in Wenjiang Structure are favorable prospects for recent exploration.
