利用异常高地层压力(或者超过静水压力的地层压力)信息作为普查油气藏的标志,是个研究工作比较薄弱的问题,研究者们对此意见不一。根据多年研究结果。我们认为引起异常高地层压力的原因是多方面的,因此,不能说它是万能的方法,或者是可以广泛推荐,认为在任何一个地区都是有效的。我们认为利用异常高地层压力信息寻找油气聚集区,必须从两个基本方向入手。(1)在烃聚集与异常高地层压力形成过程的关系已查明的地区,利用异常高地层压力信息可以作为含油气远景的直接标志。(2)利用异常高地层压力信息作为油气生成和油气藏形成与保存的有利条件的间接标志。这一点还应该分为利用异常地层压力信息作为天然油气藏的封闭标志;利用各个层的异常高地层
Researchers have different views on using the information of abnormally high formation pressure (or formation pressure exceeding hydrostatic pressure) as a marker for the census reservoirs, which is a relatively weak research work. Based on years of research results. We believe that the causes of abnormally high formation pressure are manifold and therefore can not be said to be a panacea or can be widely recommended as valid in any one area. We believe that the use of abnormally high formation pressure information to search for hydrocarbon accumulation areas must start from two basic directions. (1) In regions where the relationship between hydrocarbon accumulation and abnormally high formation pressure has been identified, the use of abnormally high formation pressure information can serve as a direct indicator of hydrocarbon-bearing visions. (2) Use of abnormally high formation pressure information as an indirect indicator of hydrocarbon generation and favorable conditions for the formation and preservation of oil and gas reservoirs. This point should also be divided into the use of abnormal formation pressure information as a natural seal of the natural gas reservoir; the use of the various layers of the abnormal high formation
