摘要
塔河油田缝洞型油藏以溶洞、裂缝为主要储运空间,缝洞非均质性很强,其流体流动机理和含水率变化特征与一般砂岩油藏区别较大。基于管流理论建立了一种新的流动模型,并分别模拟了弹性开发和注水开发时缝洞型定容油藏的开发特征和含水率变化特点。该研究对于认识缝洞型油藏流体流动机理具有一定的借鉴意义。
Solution cavity and fractures constitute major reservoir space in Tahe Oilfield.Fractures and cavities are highly heterogeneous,with fluid flow mechanism and water cut quite different from common sandstone reservoirs.A new flow model is set up based on conduit flow theory,and is used to simulate development performance and water cut of fracture-cavity constant volume reservoirs developed respectively by elastic drive and water flooding.This study is a reference in understanding fluid flow mechanism in fracture-cavity reservoirs.
