再探地下水对气藏形成的影响

A FURTHER DISCUSSION OF THE RELATIONSHIP BETWEEN THE FORMATION OF NATURAL GAS RESERVOIR AND UNDERGROUND WATER

本文再次从理论上分析了地下水与油气作为统一的流体系统,在地下所经历的油气生成、运移、聚集到被破坏、再分布、再聚集的全过程,进一步论证了地下水与气藏形成和分市的关系,并结合国内外的实例,指明了利于大中型气田形成的条件。

Underground water,oil and gas,which as an unified system,are respon- sible for the whole process of hydrocarbon generation,migration and accu- mulation reserve distorition,redistribution and reaccumulation.This paper gives a further discussion on the relation between the gas pool formation and underground water.Combining the theory with some case studies,this paper also demonstrates the genetic characteristics of large and medium- sized gas field.
