智能井系统通过安装封隔器和流体控制阀,实现分层控制下的多层合采。各产层流体自ICV流入井筒,并在井筒中汇集后流出井口。想要实现多层合采井的优化生产,必须通过井筒压降模型准确计算出各层产量。在实际生产中,有效地利用智能井系统中的流量控制技术,可以快速有效地对各产层的流入流体进行控制,使得油藏的开采更加合理化。同时,还可以延迟水/气侵,延长井筒的开采寿命,最终达到提高采收率的目的。因此,结合智能井的结构特征本文对井筒压降影响因素及模型研究进行了研究分析。
Intelligent well systems enable multi-ply mining with layered control by installing packers and fluid control valves. Each production fluid flows from the ICV into the wellbore and out of the wellhead after it has been collected in the wellbore. To achieve the optimal production of multi-layer well, we must accurately calculate the production of each layer through the wellbore pressure drop model. In actual production, the effective use of intelligent well system flow control technology, can quickly and effectively control the inflow of fluids in each formation, making the reservoir more rationalized mining. At the same time, it is also possible to delay the water / gas invasion and prolong the life of the wellbore, ultimately achieving the goal of enhancing oil recovery. Therefore, combined with the structural characteristics of intelligent wells in this paper, the factors that affect wellbore pressure drop and model studies are analyzed.
