为了深入了解地层产生异常高压的原因, 该文研究了抬升作用使地层产生异常高压的可能性。研究认为, 由于水的热压变形比较高, 地层抬升使其产生异常高压的可能性非常小。油气藏产生异常高压需要较大的抬升幅度, 一般情况下难以出现。因此, 大多数地层的异常高压依然是外来流体的侵入造成的。

In order to make clear the cause of abnormal high pressure in formation, a study is carried out on the probability that uplift of formation can result in abnormal high pressure. The result shows that due to the high ratio of thermal expansion coefficient to compressibility of water, uplift can not cause abnormal high pressure in formation.The abnormal high pressure in oil and gas reservoirs requires a large height of uplift, which is unpractical generally.So the main cause of abnormal high pressures is still the invasion of external liquid into closed formations.
