摘要

摘要: 在油气运移过程中,由于运移的层析效应、氧化变质、热变质作用及水动力条件的变化,使地层流体即油气水的物理化学性质产生一系列的变化,从而获知有关油气运移及保存方面的信息.研究结果表明,断裂是彩南油田深部油气向上运移、渗入水向下渗透的通道,上、下运移的流体均有水平顺层运移的特点.渗入水阻碍了油气继续向上散失,对浅层次生油气藏的形成起到了推动作用.侏罗系西山窑组在彩南北断裂以西与彩南断裂以东不是一个水动力系统;并且彩南北断裂以西地层水水动力较弱,有利于油气的保存.侏罗系八道湾组在彩南北断裂以西与彩南断裂以东应属于同一个水动力系统,且矿化度均较高,有利于油气的保存.

Abstract: In the migration process of oil and gas,the liquid's features may change because of oxidation-deterioration and thermal-deterioration and the change of the hydrodynamic force.So the information about the migration and preservation of oil and gas can be learned from the features of the liquids in formation.The results indicate that the fault can act as a passage for the liquid flowing,including oil and gas's migration and water's permeating.The flowing includes horizontal way along the formation.The permeating water obstructs the oil and gas migrating and disappearing.The Cainan North Fault and Cainan Fault in Jurassic Xishanyao Formation are not belong to one hydrodynamic force system,and the hydrodynamic force is weaker in the west of the Cainan North Fault than in other areas.The weaker hydrodynamic force is good for the hydrocarbon preservation.The Jurassic Badaowan Formation is one hydrodynamic force system in the west of the Cainan North Fault and the Cainan Fault,and the higher water salinity is good for the preservation of oil and gas.
