Abstract

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.

Key words: offshore unconventional heavy oil, thermal flooding, steam, multiple thermal fluid, hot water, gas channeling
