摘要

东营凹陷油气环带状分布与古生物场、古地温场、古应力场及古水势场的性质、强度存在明显的内在联系

“场环对应理论”可很好地解释并进一步深入认识其内在规律。古生物场决定沉积有机质的性质与丰度;古地温场提供有机质向烃类转化的能量;古水势场及古应力场为烃类运移提供动力和储集空间。因此

“四场”的环状分布控制着油气的环状分布

围绕“四场高势区”的圈闭带寻找油气富集区可作为油气勘探的一条指导原则。

Abstract

The girdle distribution of hydrocarbon in Dongying Depression bears close inherent relation with the properties and strenghs of the fields of paleobiology

paleogeotherm

paleostressand paleofluid potential.The girdle distribution of oil and gas puts forward the "field-girdle corresponding theory".Paleobiology field determines the character and abundance of deposited organic matter; paleogeothermal field provides the energy with which organic matter could be transformed into hydrocarbon; paleofluid potential and paleostress fields offer power and space for hydrocarbon migration and preservation.Therefore

the ring-type distribution of the above mentioned four fields has controlled the girdle distribution of oil and gas.Seeking for oil and gas enriched zone around the high potential belts of the four fields is of guiding importance in hydrocarbon exploration.
