钟市潜二段开发后期储层地质建模研究

Geologic Modeling Study of Zhongshi 2nd Member of Qianjiang Formation in Jianghan Oilfield

江汉油田钟市潜二段油层多,油水井出力状况差异大,已经进入开发后期,开发矛盾.日益明显。针对该区块油井多、储层非均质强等特点,应用Petrel软件,综合应用地质、测井、地震等数据建立沉积相概念模型。采用相控建模技术建立孔隙度模型;采用协同模拟方法建立渗透率模型;采用确定性与随机性结合的方法建立含油饱和度模型。该方法对完善注采井系统,提高采收率具有良好的指导意义,为进一步的油藏开发提供了依据。

In the Zhongshi 2nd Member of Qianjiang Formation in Jianghan Oilfield,reservoir condition is poor.The contribute of oil and water well is disparities.The Oilfield is at the late stage of development,condition is increasingly obvious.For wells in the block and reservoir heterogeneity,and other characteristics,by using Petrel software and integrated application of geologic,logging and seismic data,conceptual model of sedimentary facies is setablished. Facies-controlled technologies are used to create porosity models;collaboration simulation methods are used to established a permeability model,and deterministic and random combination methods are used to establish a saturation model.This method can improve the system of injection wells,enhance oil recovery,it provides the basis for further development.
