摘要 我国油田开发的中后期,常用注水的方式来提高地层能量。由于油层的非均质性,会出现水"突进"以及"窜流"等问题。如果严重的话,还会极大影响油田的开发效果。渤海湾海上稠油砂岩油藏,长期实施注水开发,加剧了储层的非均质性,导致含水率上升过快,产量下降快等问题。为了改善注水效果和提高采收率,在油田开发的过程中应用堵水调剖技术。对渤海湾调堵技术的发展现状进行了相关的分析。 At present,in the development of the oil field in the late stage,a lot of oil field used injecting water to supply energy of formation.Because the reservoir is not very uniform,so it will lead to problems like”channeling”and“water break through”,if worse,may also have a significant impact on the development of oil fields.Especially in the Bohai Bay offshore heavy oil sandstone reservoir,serious reservoir heterogeneity,cementation,long-term water-flooding development,reservoir surface and vertical heterogeneity intensified,lead to water rise too fast,rapid decline in output and other issues.Therefore,in order to improve the water injection effect and the final oil recovery rate of the oil field,it is necessary to actively use the technical measures of water shutoff and profile control in the process of oilfield development.This paper mainly focuses on the development of Bohai Bay water shut-off and profile control technologies.
