摘要
50年代至60年代期间,是松辽盆地广泛开展石油普查最兴盛的时期,亦即所谓“一轮”石油普查时期。在此期间,综合地球物理勘探在石油普查中起到了先行作用。由地球物理资料提供的局部构造上首次获得工业油气流,打开了开发大庆油田的新局面。与此同时,松辽盆地南部(第二松花江以南),在扶余三号构造上亦获得了工业油流,为开发江南地区扶余油田创造了条件。 本文着重介绍松辽盆地南部石油普查勘探的工作程度、成果和对松辽盆地南部含油远景的评价与展望。
Abstract
During fifties and sixties, it was the most flourishing period of conducting oil reconnaissance survey widely in Songliao Basin, which is taken as the "1st Round" of the survey. In this period, the integrated geophysical prospecting technique was playing a vanguard role. As a result, the crude oil of commercial value was, for the 1st time, discovered on the local structures based on the geophysical information available. It opened up a new prospect for developing the Daqing Oilfield. Meanwhile, petroleum of commercial value was successfully detected slso on thestructure named Fuyu No. 3 located in the south (the 2nd Songhua River southwards) of Songliao Basin so that it has created favourable conditions for developing the Fuyu Oilfield in S.-Yangtze River.The paper focuses its presentation on the progress being made in oil reconnaissance survey conducted in southern Songliao Basin. Also, the posisive results achieved, assessment and long-range oil bearing prospe-ctives of Songliao Basin are made and recounted as well.
