齐108块莲花油藏属于典型的中薄互层状普通稠油藏,1990年投入热采开发,通过注汽参数优选,以及吞吐中期以后采取调层补孔、侧钻、分注、调剖等措施,提高了储量动用程度,吞吐阶段开发指标接近于方案指标。目前进入高周期吞吐,地层压力低及层间矛盾突出为该块主要矛盾。为了寻求吞吐后期有效开发手段,对该块齐210断块莲Ⅲ下蒸汽吞吐开采效果进行评价,初步分析了该块转换开采方式的可行性思路。
Qi 108 lotus reservoirs belong to the typical medium and thin interbedded common heavy oil reservoirs. In 1990, they were put into thermal exploitation and development. Through the optimization of steam injection parameters, And other measures to improve the utilization of reserves, throughput stage development indicators close to the program targets. Currently entering the high cycle throughput, low formation pressure and prominent contradictions between the layers of the main contradiction. In order to seek effective means of post-throughput development, we evaluated the effect of steam huff and puff on the Block 210 with block lotion Ⅲ, and analyzed the feasibility of this block conversion mining method.
