| 摘 要： | 研究以室内试验和数值模拟结论为基础,利用CO2的压缩性提高油层压力,提高油井的驱动能量,同时利用CO2的溶解降粘和萃取作用降低地下原油粘度,改善原油流动性,为稠油开发方式的转换提供理论和试验依据。2001年先后在辽河油田冷42块、高3624块和锦45块进行6井次先导试验,通过现场试验和经济分析认为,该技术是一种经济可行的稠油开采方法。

| Abstract: | This research is dedicated to the reservoir which is deeper partially with the results of inefficient steam huff and puff. The new enhanced oil recovery pilot technology is experienced in the deep pay-zone from which the viscous oil can not be withdraw by the conventional technology and the high frequency cyclic steam pilot reservoir could not be effectively recovered. This project can increase the driving energy for the oil well by the means of CO2 compressibility meanwhile the CO2 with solubility and extractive ability can reduce the crude oil viscosity as well as improve the flow property base upon the conclusion of laboratory experiments and numerical simulation, so that it can provide the theoretical basis and case history for the recovery mod transition. The case for this kind of CO2 stimulation has been applied in the blocks, such as Leng-42、Gao-3624 and Jin-45 blocks with in 6 wells. The CO2 cyclic stimulation should be economical feasibility and cost effective technology with low investment on the basis of field testing and economical evaluation. |
