摘　　要：运用密闭取心分析、室内模拟等手段．量化了高升油田莲花稠油油藏热采过程中储层孔隙结构、物性变化的一般规律，并针对高轮次吞吐及老井侧钻效果较差的局面，提出了层系互换、补孔解堵、大位移侧钻等开发对策。从而改善了低压状态、高轮次吞吐井开发效果，并延长了有效开发期。Pore structure and physical propert les of Lianhua heavy oil reservoir ofGaosheng oil field during thermal recovery are quantized by analyzing sealing core and indoormodeling. In accordance with the situation of multicychec steam soak and unsatisfactory effectof side drilling in old wells, this paper puits forward some development measures, they are interchanging of series of strata, plug removal by reperforating, and long displacement sidedrilling- Development result of low pressure state, multicyclic steam soak well is improved,effective development period is prolonged.
