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。计算了地下不同埋深的储集体产生的重力异常值以及注水驱动前后引起的重力异常差值。详细分析了地面超导重力观测和井中超导重力观测的分辨率，地面超导重力观测能够分辨出深１０００ｍ，厚５ｍ以上的储集体；井中超导重力观测可以不受埋深的影响，能分辨出井距为７５ｍ，厚２ｍ和半径５ｍ以上的储集体。地面超导重力仪和井中超导重力仪结合起来使用是油田进一步寻找剩余油气的可行的方法之一。
Based on the principle of gravity exploration and the observation accuracy of superconducting gravimeter, the migration and accumulation of remaining hydrocarbons were studied. The gravity anomalies produced by reservoirs with different burial depths are calculated and the gravity anomalies caused by water flooding are calculated. The resolution of ground superconducting gravity observation and well superconductivity gravity observation are analyzed in detail. Ground superconducting gravity observation can identify reservoirs with a depth of 1000m and a thickness of more than 5m. The superconducting gravity observation in a well can be independent of the depth of burial. Identify the reservoir spacing of 75m, thickness 2m and radius 5m above. The combination of terrestrial superconducting gravimeter and well superconducting gravimeter is one of the feasible methods for oilfields to further search for remaining oil and gas.
