我国1/20万到1/100万小比例的重力工作基本上是在五十年代——六十年代为进行石油普查而做的。当时对获得的布格重力异常图配合航磁、电测深和地质资料进行了定性——半定量的综合地质解释,在圈定沉积盆地轮廓,划分盆地内的次一级构造单元,指明含油远景区等方面起了重要的作用,取得了较好的地质效果。二十多年过去了,在此期间石油重力工作几乎处于全面停顿状态,似乎重力作为一
China’s gravity work of 1/20 million to 1/100 million is basically done during the oil census in the 1950s and 1960s. At that time, the obtained Bouguer gravity anomaly maps were combined with aeromagnetic, electrical sounding and geological data to carry out qualitative-semi-quantitative comprehensive geologic interpretation. After delineating sedimentary basin contours, sub-level tectonic units in the basin were designated, District and other aspects played an important role, and achieved good geological results. Twenty years have passed, during which time the petroleum gravity work was almost in a state of complete standstill,
