摘要:
陈371区块稠油多轮次蒸汽吞吐后注汽效率下降、含水快速增加,试验冷热采交替吞吐工艺效果明显,但致效机理不明确。为此,利用油藏数值模拟方法,研究了油井在不同周期下的冷热采交替的生产效果,综合考虑周期产油量和经济效益,确定了高液高含水、中低含水和低产低液3种生产井况下的油井冷热采交替最佳时机,优化了冷热采交替吞吐方式及关键的注入参数。经21口井的应用,平均单井日产油4.9 t,周期产油量677.8 t,取得较好的效果。研究成果对提高稠油油藏冷热采交替吞吐开发效果具有重要的意义。
Abstract:
The steam injection effectiveness dropped and the water content rapidly increased after multiple rounds of steam huff and puff for heavy oil in the Chen 371 block. Although the effect of the cold alternating hot huff and puff process is obvious,the mechanism involves in it is unclear. Therefore,under comprehensive consideration of cycle oil production and economic benefits,the production effect of cold alternating hot production of oil wells in different cycles is investigated using the reservoir numerical simulation method. Under three different production well conditions—high-liquid and high water-cut,medium and low water-cut,and low production and low liquid,the optimal timing of cold alternating hot production of oil wells is recognized,and the mode and key injection parameters of cold alternating hot huff and puff production are optimized. After the application of 21 wells,the average daily oil production of a single well is 4.9 t,and the periodic oil production is 677.8 t,which has achieved good results. The research results are of great significance for improving the development effect of cold alternating hot huff and puff production in heavy oil reservoirs.
