摘要: 针对目前渤海地下原油黏度大于350 mPa·s的非常规稠油水驱采收率较低,且考虑到吞吐轮次及平台寿命的问题,开展吞吐后续转驱开发方式研究。以海上M稠油油田为例,利用油藏数值模拟方法对蒸汽吞吐转蒸汽驱、热水驱及多元热流体吞吐转多元热流体驱、热水驱等4种转驱方式的转驱时机及注采参数进行优化设计及对比分析。结果表明,蒸汽吞吐转蒸汽驱开发效果最好,多元热流体吞吐转多元热流体驱略差。蒸汽驱最优注入参数为:转驱压力5 MPa左右,采注比1.3,井底蒸汽干度0.4,注入温度340℃,注汽速度240 m3/d。

Abstract: This research focused on low recovery efficiency of water flooding of unconventional underground heavy oil at Bohai, which had a crude viscosity greater than 350 mPa·s. Additionally, the research was based on the cycle of huff and puff and platform life. Offshore M heavy Oilfield was taken as an example. A numerical reservoir simulation was performed to optimize the design. This was used to compare and analyze the flooding time, as well as the injection and production parameters of four flooding patterns, namely, steam huff and puff turning into steam flooding, hot water flooding turning into multiple thermal fluid flooding, multiple thermal fluid huff and puff turning into multiple thermal fluid flooding, and hot water flooding. The results indicate that steam huff and puff turning into steam flooding has the best effect, and multiple thermal fluid huff and puff turning into multiple thermal fluid flooding has a relatively unfavorable effect. Optimal parameters of steam flooding are as follows:the flooding turning pressure is approximately 5 MPa, production-injection ratio is 1.3, steam quality at the bottom of the oil well is 0.4, injection temperature is 340℃, and steam injection speed is 240 m3/d.
