The migration force of oil is bigger than that of water and increases constantly during the source of compaction of water-wet sandy and argillaceous sediment.
在亲水砂质、泥质沉积物的压实过程中，油的运移阻力大于水，而且，在压实过程中油的运移阻力是不断增大的。
The petroleum migration mainly in an oil phase, as for natural gas migration, it can occur in water-solution, oil-solution, free gas and diffusion phase.
石油运移的相态主要是油相，天然气可以是水溶相、油溶相、气相和扩散相。
The method is coincident with the thought of fine geological research and provides the scientific basis for predicting oil and water distribution dynamic by time migration seismic technique.
该方法符合精细地质研究的思想，为用时移地震技术预测油、水分布的动态信息提供了科学依据。
