摘要
为提高扶余油田稠油区块注水开发效果,针对稠油区块开发中存在的主要问题,结合区块储层特征,开辟了东17区块先导试验区,对试验区开发效果进行了系统的跟踪评价。结合试验区动态反映及地质特征采取调剖与降黏剂相结合的技术路线,改变油层的非均质和地下油品的流动性,提高宏观波及系数和微观驱油效率,增加可采储量。该先导试验取得了较好开发效果,该项技术的成功实施,为扶余油田类似区块的注水开发提供了技术支持。
Water flooding is adopted to develop the heavy oil in Fuyu Oilfield.A pilot test area,Block Dong17 was established to tackle the problems encountered during the development of heavy oil blocks considering the reservoir characteristics of the block,and the development results in the test area were systematically traced and evaluated.Taking the performance responses and geological features in the test area into consideration,the technology of combining profile control with viscosity-reduction was applied to changing formation heterogeneity and underground oil flow properties,improving macroscopic sweep efficiency and microscopic displacement efficiency and increasing recoverable reserves.Satisfactory results have been achieved in the pilot test area and the success of the technology has provided a technical support for water flooding in similar blocks of Fuyu Oilfield.
