Abstract: Thin layer sandstone prediction is a major problem in reservoir lateral description.In this paper,the structure,physical parameters,lateral variation of a reservoir could be accurately predicted by the technology of comprehensive constrained seismic inversion.This method greatly improved the resolution of the impedance profile and the reservoir prediction.It was used in the thin layer sandstone reservoir description of the Eogene System in Boshizhuang and was proved to be effective.Furthermore,the petroleum system of the E_s2 and E_s3 petroliferous layers in the Eogene System were analyzed,the favourable prospects for oil exploration were delineated out,such as XL10 E_s2 fault structural nose oil reservoir,G103 E_s2 lithologic structural oil reservoir,and G43 E_s3 structural lithologic oil reservoir.

Key words: comprehensive constrained seismic inversion, reservoir description, evaluation, Eogene, Boshizhuang area

摘要： 薄层砂体横向预测是油藏描述的关键性技术环节.运用地质、测井约束条件下的地震综合反演技术,提高了波阻抗剖面的分辨率和储层物性参数的预测精度,对博士庄地区下第三系内陆河湖相薄层砂体进行了以构造解释和储层预测为主要内容的油藏描述.在此基础上,结合石油成藏系统的研究思路,预测了该区下第三系沙二、三段含油目的层系的石油运聚成藏条件、富集规律及其有利的圈闭类型和勘探方向.综合分析认为,博士庄地区沙二、三段含油层系在不同构造区分别属于3种圈闭类型及相应的5个油藏,其中尤以XL10井沙三段断鼻构造油藏、G103井沙二段岩性构造油藏和G43井沙三段构造岩性油藏最具勘探远景.
