The residualgravity anomaly was mainly produced by rolling basement of the basin and the regional gravity anomaly by the Moho rolling.
推断引起剩余重力异常的主要原因是盆地基底的起伏，引起区域重力异常的主要原因是莫霍面起伏。

Based on the theory of gravity prospecting and measuring accuracy of superconductive gravimeter, the migrating and accumulating of residual oil and gas are studied.
以重力勘探原理和超导重力仪观测精度为依据，对剩余油气的运移和聚集进行了研究。

However, there occurs 5-70 milligals gravity anomaly in this region, the residual anomaly being 30-50 milligals after eliminating the effect of Mohorovicic discontinuity.
