摘　　要：本文以东辛、永安镇油气田为例,对复杂断块油气田的油气水性质、分布规律及影响因素进行了初步研究。研究表明,断块油气田流体性质复杂多变,埋藏深度制约流体性质在纵、横向上的变化,深部地层油轻气重水咸,浅部地层油重气轻水淡。次生变化是决定原油性质变化的主要因素。The properties and distribution characteristics of fluids in complicated fault-block oil and gas fields have been studies on the basis of geological data from the Dongxin and Yonganzhen oil-gas fields. The study results show that the properties of fluid in fault-block oil-gas field are highly complicated and controlled by the burial depths of the reservoirs ;with increasing buried depth, oil become light,gas becomes heavy and the salinity of formation water increases. It is pointed that secondary change is the main factor determining the changes of oil properties.
