摘要:
针对蒸汽吞吐开发后期出现的地层能量不足、油层动用半径有限、蒸汽波及系数低、油藏非均质性导致井间干扰等极大影响超稠油开采的问题,通过理论计算、数值模拟等方法进行非凝析气体CO2辅助蒸汽吞吐技术可行性研究。现场超稠油井组试验结果表明,此技术效果明显改善,增油3 191 t,创效益378万元,对超稠油蒸汽吞吐开发后期改善高轮井吞吐效果、提高油田采收率作用显著。
Abstract:
The production problems in the late stage of cyclic steam stimulation are insufficient formation energy,limited producing radius,low steam sweep efficiency,well interference caused by reservoir heterogeneity,and so on.These problems have a great effect on the production of super heavy oil.According to the theoretical calculation and numerical simulation etc.,it was carried out study on the technical feasibility of steam huff and puff assisted by non-condensable CO2 gas.The pilot results of well group indicated that the steam huff and puff effect was obviously improved by the technology,the cumulative incremental oil production was 3,191tons,and the increased income was 3.78 million RMB.The technology has a significant influence on improving the effect of cyclic steam stimulation and the oil recovery in the late stage of cyclic steam stimulation.
