辽河坳陷N区块潜山裂缝性油藏地质建模
|
摘要
受测井、地震、地质等资料种类及品质的限制,辽河坳陷N区块潜山裂缝油藏自开发以来缺乏有效、准确的地质模型。本课题以测井资料为基础,使用三维有限元反演法较准确地计算裂缝性储层参数,借助地质建模软件分层段建立岩性相控三维地质模型。裂缝性储层参数计算结果及三维地质模型与勘探及开发结果相吻合,研究结果表明,使用该方法建立潜山裂缝性油藏地质模型有效可行,为该类油气藏岩性、储层分布规律研究、开发方案设计及油藏数值模拟提供了准确的数据及基础模型。
Restricted by the type and quality of logging,seismic,and geological data,an effective and accurate geological model is not available for the fracture reservoirs of Block N in Liaohe depression since development.In this research,based on the logging data,3Dfinite element inversion method is used to calculate the parameters of fracture reservoirs accurately.The geological modelling software is utilized to establish a lithology phase controlled 3Dgeological model divisionally.The calculated parameters of fracture reservoirs and 3Dgeological model are coincident with the exploration and development result.The study shows that this method is both effective and feasible for modelling the buried fracture reservoirs,which provides an accurate and fundamental data model for the research of reservoir lithology and distribution regularity,design of the development program plan and numerical simulation of reservoirs.
