摘要/Abstract

摘要： 辽河西部箕状凹陷陡坡带砾岩稠油油藏的发现是我国东部近几年在油气勘探上的重要突破之一.本文应用沉积学、构造地质学、地震地层学、石油地质学理论在综合分析工区内地层、构造、沉积微相、储层、流体性质及油藏地质特征基础上,总结出砾岩稠油油藏的形成除具备一般成油条件外,有利储集相带与断块、断鼻的最佳迭置以及构造单元和断裂带对油气富集控制明显,进而阐明了重质稠油的地质成因.根据原油性质及成熟度,结合圈闭成因,本区油气藏分为低成熟正常原油断块-岩性油藏、低成熟重质稠油断块-岩性油藏、低成熟重质稠油断块油藏三类;综合考虑烃类成熟度和次生稠变,重质稠油藏可分为次生运移型和底水氧化型两种,并总结了各类油藏地质特征,在研究砾岩稠油油藏分布规律基础上,探讨了油藏分布序列,建立本区油藏分布模式.对今后高效勘探开发提出了合理化建议,指出了有利含油地区.

Abstract: Tbe discovery of conglomeratic heavy oil reservoir in the complex steep slope-zone inLengdong-Leijia area in west of Liaohe depression is one of the important break through inoil and gas exploration in the eastern part of China in recent years.Based on a comprehensive analysis of stratum,structure,sedimentary facies,reservoir,and fluid properties and geological features of oil pool in this region,by using the theories ofapplied sedimentary,structural geology,seismic stratigraphy and petroleum geology,it is concluded that besides the general conditions beneficial to the formation conglomeratic heavy oilreservoir,other conditions,such as a best association of reservoir formation and structural u-nits and faulted zones,have an obvious controlling effect on oilgas accumulation,And theprocess of conglomeratic heavy oil reservoir forrnation is described.According to the property and maturity of crude oil combined with the genesis of traps,oilgas reservoirs in this region are classified into three types:faulted-lithologic ones withnormal crude with low maturity,faulted-lithologic ones with low maturity and fauIted-blockones with heavy oil through synthetic consideration of maturity of hydrocarbon and secondary transformation to heavy oil,the heavy dense oil reservoir can be classified into twocategories:secondary migration type and the other of bottom-water oxidization type. Thecharacteristics of every type are summarized also.Based on a study of distribution of con-glomeratic heavy oil reservoir,a distribution sequence of reservoirs is explored and distribution models of reservoir in this region are constructed.Through a combination of distribution tnodels of conglomeratic heavy oil reservoir inthis region,a reasonable advice for highly effective exploration and developement has beenput forward and favorable oil-bearing areas have been pointed out.

Key words: west slope of Liaohe, hydrocarbon reservoir of conglomorate, heavy oil reservoir, form of hydrocarbon reservoir, type of hydroarbon reservoir, distribution of hydrocarbon reservoir
