摘要
在油气勘探中 ,地震是确定构造形态的有效方法 ,而高精度重力测量能观测到具有工业意义的油气藏及其伴生因素产生的重力负异常。通过对高精度重力异常和地震确定的地质界面相关分析得出的油气重力异常与构造形态之间的不相关性来预测油气藏 ,理论模型试验和应用实例均表明 ,方法正确 。
In oil and gas exploration,the seismic method proves to be effective in determining geological interfaces,and high precision gravity survey can observe negative gravity anomalies caused by commercial reservoirs.On the basis of correlation analysis of gravimetric and seismic data,the method for predicting oil and gas reservoirs using the incorrelate property between gravity anomalies caused by oil (gas) pools and geological interfaces is recounted.The model trial and applied examples show it to be effective and applicable.
