吐哈低孔低渗油田精细油藏描述

Fine Reservoir Description of Low Porosity and Low Permeability Reservoir in Tuha Oilfield

吐哈油田以陆相非均质性严重的低渗透砂岩油藏为主,加之储层的低孔隙特征和复杂的断裂系统特征,常规的精细油藏描述方法远远不能满足油田综合研究,经过几年的实践,综合应用地震、测井和大量的油田动静态资料,采用多学科协同研究,精细油藏描述和开发调整一体化技术攻关运行模式,高效地将综合地质研究、潜力评价和开发调整有机的结合起来,形成了一套适用于低孔低渗油田的精细油藏描述技术方法,实现了资料、信息、人力、技术和研究成果的充分共享和有效的匹配,研究成果在油田的开发调整中取得了良好效果。

Tuha oilfield is dominated by low -permeability sandstone reservoirs with terrestrial facies and serious heterogeneity, the reservoir is characteristics of low porosity and complex fault system characteristics. The conventional method of fine reservoir description cannot meet the need of comprehensive study of the oilfield. After several years of research and practice, overall applying seismic, logging and static and dynamic data, based on multi -disciplinary collaborative study and integration technology of fine reservoir description and development adjustment, miscellaneous geologic investigations, potential evaluation and development adjustment are combined efficiently, and a set of fine reservoir description techniques that are fit for low porosity and low permeability oilfield have been formed, which achieve full -sharing and effective matching of the data, information, manpower, technique and research results. The finding has taken a good effect in the development adjustment of the oilfield.
