Based on the grey system study of oil and gas information, the grey positioning method for forecasting geophysical anomaly of oil and gas trap is put forward.

基于油气信息灰色系统研究，提出了油气物探异常灰色定位预测法。

Due to far away from the hydrocarbon source rock, oil-gas migration and building-up conditions became the main controlling factor of the formation trap reservoir forming.

由于距离烃源岩较远，油气运移聚集条件成为地层圈闭成藏的主要控制因素。

Finally, we can predict the reservoir and evaluate the oil-gas trap in the light of the sandstone distribution and geological structure.

再根据砂层分布规律和构造特征进行储集层的预测和油气圈闭评价。

Moffett has often called attention to the fact that the Mississippi River has been flowing down the center of our country for 60 million years and dumping sediment into the Gulf all the while, ultimately creating mounds and valleys that could trap debris that was eventually turned into oil and gas.
