Optimizal Method of Offshore Oil Artificial Lift Modes Based on Hierarchical Grade-Weighted Method

CNOOC Research Institute, Beijing, 100028, China

摘要

摘要: 目前海上油田总体开发方案中,机械采油方式优选方法单一,以定性指标为主,缺乏必要理论支撑与数据支持。为此,综合考虑技术指标、经济指标、工程指标的影响,以机械采油方式优选为目标,采用等级加权法对技术、经济和工程3个指标的影响因素进行赋值以及分配权重,建立了海上机械采油方式优选方法。利用该优选方法对海上X稠油油田的机械采油方式进行了优选,开发初期产液量为40~108 m3/d时,推荐采用螺杆泵开采;开发后期产液量达到200 m3/d时,考虑X油田为稠油油田,应采取降黏措施,推荐采用电潜泵+掺稀/化学降黏方式开采。优选结果与该油田总体开发方案中的机械采油方式一致,且该油田机械采油方式与优选结果一致的井,都正常生产。这表明基于等级加权法的机械采油方式优选方法可以指导海上油田选用合理、经济、对海洋工程影响较小的机械采油方式,从而提高海上油田的开发效益。

Abstract: Currently, the method used for optimizing mechanical artificial lift methods in offshore oil fields is developed during the overall development plan.Generally speaking, there is insufficient theoretical support or data available in these processes.For that reason, it is important to develop a new analytical approach that incorporates all relevant technical, economic, and engineering factors.To improves the process, a hierarchical, grade-weighted method can be deployed to assign these three indicators for establishing a model of optimal offshore artificial lift.The newly developed method has been deployed for identification of optimal artificial lifts in X Oilfield for heavy oil development.The result shows that in the early stages of development, liquid production was 40-108 m3/d, and accordingly, a screw pump was proposed for its development.In the late stages of development, with liquid production was above 200 m3/d, ESP and dilution or chemical viscosity-reducer should be deployed to reduce viscosity of heavy oil.Results obtained by using the proposed method coincided with those specified in an overall development plan.In addition, all optimal wells that adopt artificial lift techniques identical to selection results have normal production.It can seen that the hierarchical grade-weighted method can could be deployed to identify artificial lifts with outstanding economic performances that will enhance the recovery in offshore environments.Eventually, the development efficiency in offshore oil and gas fields can be dramatically enhanced.
