影响稠油火驱开发因素分析及对策

摘要

曙光稠油火驱已经进入规模实施阶段,针对储层纵向上动用差异大和平面上油井见效不均等开发矛盾,在对储层物性、吸气状况、注空气参数进行再分析研究的基础上,对注入方式和注空气参数进行了优化.解决了火烧油层过程中气窜、受效不均及跟踪调控难度大等问题,火驱开发效果明显改善、产油量大幅提高.为曙光稠油火驱开发方式提供了有力的技术支持,也为同类油藏的开发提供借鉴.%Shuguang heavy oil fire flooding has entered the stage of scale implementation. With regard to the reservoir longitudinal utilization difference and uneven development of oil wells on the surface,based on the re-analysis of reservoir physical property, gas suction condition and gas injection parameters, the injection mode and gas injection parameters were optimized. The method solves the difficulties of gas channeling,uneven effect and difficult tracking and control in the process of in situ combustion,improving the development effect of fire flooding and oil production greatly. It also provides a powerful technical support for the development mode of Shuguang heavy oil fire flooding and a reference for the development of similar reservoirs as well.
