以胜利大芦湖油田樊 12 8块油藏为例 ,以整个油藏 (包括含在其中的水力裂缝 )为研究单元 ,以整个油藏未来的开发、调整和压裂效果评价为着眼点 ,以地质与生产动静态资料为参数覆盖依据 ,并用模糊多因素决策方法为优选最佳缝长的评价方法 ,最终提出了一套新的整体压裂优化设计的概念和方法。该研究模式能综合考虑储层有效渗透率、有效厚度、目前地层压力以及油井含水率等多种因素的影响 ,因而能精细提供油藏在不同开发生产阶段进行水力压裂时的最佳缝长设置 ,从而改变了过去整体压裂方案过于笼统、抽象的缺点 ,以及在指导单井压裂设计时的针对性和有效性不强的局限性。经其他可靠手段验证 ,此研究结果可靠 ,且简单易行 ,便于现场应用
Taking Fan 12 8 reservoirs in Daluhu Oilfield, Shengli, as an example, taking the entire reservoir (including the hydraulic fractures contained therein) as the research unit and focusing on the future development, adjustment and fracturing evaluation of the entire reservoir, The static and dynamic data of geology and production are used as the parameters to cover the data, and fuzzy multi-factor decision making method is the best method for evaluating the optimal seam length. Finally, a new set of concepts and methods of overall fracturing optimization design are proposed. The study mode can comprehensively consider the influence of many factors, such as effective reservoir permeability, effective thickness, current formation pressure and well water content, so as to provide the best seam length for hydraulic fracturing in different stages of development and production Setting has changed the overly general and abstract shortcomings of the overall fracturing scheme in the past and pointed out the limitations and limitations of the pertinence and effectiveness in guiding single well fracturing design. Verified by other reliable means, the results of this study are reliable, simple and easy to apply on site
