针对目前华庆油田压裂水平井开发效果不理想的状况,以白豹地区为例建立实际地质模型,并在此基础上,评价工区压裂水平井开发的储层情况,优选水平井开发层位,研究储层渗透率、储层厚度、渗透率各向异性等储层参数对开发效果的影响,优化水平段长度、裂缝间距、裂缝半长、裂缝导流能力等施工参数.结果表明:华庆油田长63储层满足压裂水平井开发的适应性评价指标.考虑华庆油田储层实际情况,压裂水平井水平段长度最佳范围800-1 200 m,裂缝间距77 m,裂缝半长150 m,裂缝导流能力在15μm2·cm到20 μm2·cm之间.模拟结果对于华庆油田压裂水平井开发具有一定的指导意义.%For changing the unsatisfying development effect of fractured-horizontal well in Huaqing oil field, evaluation of reservoir parameters for fractured-horizontal well development and optimization of stratum for horizontal well development are based on the practical geological model of Baibao block in Huaqing oil field. In addition, the numerical simulation is used for the study of the effects-reservoir permeability, thickness and aeolotropism on the development and the optimization of horizontal length, fracture spacing, fracture half length and fracture conductivity. The conclusion shows that Chang 63 stratum is qualified for fractured-horizontal well development. And fitted the actual geological model, the optimizations of horizontal length range, fracture spacing, fracture half length and conductivity are 800 m to 1 200 m, 77 m, 150 m, and 15 μm2 · cm to 20 μm2 · cm, respectively. The results can be conducted for fractured-horizontal well development in Huaqing oil field.
