摘要
水平井蒸汽吞吐开采超稠油是一项非常有潜力、有优势的技术,相比直井开发,不仅能大幅度提高开发效果,而且能够进一步提高采收率。研究稠油油藏水平井蒸汽吞吐开发效果,分析地质参数及注汽参数对该类油藏开发效果的影响程度,并进行灰色关联分析。研究表明对周期产油量影响最大的因素是采注比,其次是原油粘度。
Compared to vertical wells, horizontal well cyclic steam stimulation is a good method to exploit super heavy oil; it not only can greatly improve the development effectiveness, but also can enhance oil recovery. In this paper, effect of horizontal well cyclic steam stimulation of heavy oil was studied; impacts of geological parameters and steam injection parameters on reservoir development effect were analyzed, and the gray correlation analysis was carried out.The results show that the biggest factor affecting periodic oil production is injection-production ratio, followed by the oil viscosity.
