海上稠油油藏多元热流体吞吐生产特征分析

Offshore Heavy Oil Reservoir Multi-component Thermal Fluid Huff & Puff Production Characteristics Analysis

渤海N油田稠油油藏原油粘度高,采用常规注水方式难以使储量得到有效动用,为此开展了多元热流体吞吐试验改善开发效果,现场试验表明增产效果明显,本文采用油藏工程方法开展了多元热流体吞吐试验井周期间生产特征分析,探讨了注入特征、油井产能、含水、温度和压力方面的生产特征,对多元热流体吞吐技术的推广具有积极指导意义。

Due to the high heavy-oil viscosity, it is difficult to effectively produce reserves by conventional waterflooding in oil.field N of Bohai. In view of this, the multi-component thermal fluid huff ＆ puff testing has been conducted to improve the development effect with field testing results showing obvious stimulation effect. By using reservoir engineering methods, this paper conducted periodic and interperiodic production characteristics analysis in multi-component thermal fluid huff ＆ puff testing wells, discussing production characteristics of injection, oil-well productivity, water cut, temperature and pressure, providing guiding significance for the multicomponent thermal fluid huff ＆ puff technology promotion.
