摘要
水动力学是提高油藏采收率的一种经济实用且可达到节能降耗的调整方式,国内已提出实施水动力学方法可以改善油田高含水期的开发效果,但详细论述矿场实施水动力学的工艺方法较少。特别是周期注采、降压开采等水动力学方法中的采油开关井时间、降压界限等十分重要参数的确定一直是个难题。在通过深入研究目前已有相关理论的基础,以研究大庆油田葡北Ⅱ断块为例总结出了一套适合砂岩油藏高含水期实施水动力学调整的行之有效的工艺方法,并进行了葡北Ⅱ断块现场试验。研究表明水动力学调整技术对于改善油田后期开发效果、提高采收率和节能降耗具有重要意义。
Hydrodynamics is the adjustment method of improving the oil recovery, which can be economical and achieve energy saving. National has proposed the implementation of the water dynamics can improve the development of oil effects of high water, but the process method of discussing details in the implementation process of water dynamics method is little. Particular switch the time limits, pressure drop limit of the step - down exploitation and injection cycle in the water dynamics and other important parameter determination has been a problem. Through indepth research is currently the basis of the theory, studying the case of Daqing Oil_field Pubei II to summarize a set of effective adjustment process method of water dynamics in high-water sandstone reservoirs of water dynamics, and conducted field trials in Pubei Block II. Studies have shown that hydrodynamic adjustment technique for improving the post-oil development effects, enhanced oil recovery and energy saving is important.
