确定合理的水力压裂参数是压裂设计的难点和重点,不同的地质条件对压裂设计有不同的要求,本文根据双河油田的压裂资料,重点分析了油层物性、压裂方式、排量、加砂强度和射开程度等对油井产能的影响,同时给出油层厚度与产量、压裂排量与裂缝高度的定量关系以及加砂强度与采油强度的定性关系。
Determine the reasonable parameters of hydraulic fracturing is the difficulty and focus of fracturing design, different geological conditions have different requirements for fracturing design. Based on the fracturing data of Shuanghe Oilfield, this paper focuses on the analysis of reservoir physical properties, fracturing methods, Volume, sand strength and the degree of shot on the well productivity, and gives the quantitative relationship between reservoir thickness and production, fracturing displacement and fracture height, as well as the qualitative relationship between sand strength and oil recovery strength.
