摘要
水力压裂至今一直是低孔渗储层改造的最有效措施。为了提高低孔渗油田压裂开发的整体效益和效果,为油层改造有针对性地提供施工层位和准确的储层参数,本文以胜利油气区渤南-孤北地区中生界、上古生界的低孔低渗储层为研究目标,探索、研究偶极横波测井资料在低孔低渗储层评价及改造中发挥的作用。本文充分利用偶极横波测井资料提供的纵、横波数据,结合其他常规测井资料及压裂、试油资料,建立适合本区低孔低渗油藏特性的岩石力学参数计算模型和压裂预测模型,对所改造层位进行压裂高度及施工压力参数预测,为优选压裂层位和方案设计提供依据。现场应用表明,本文提出的方法预测结果与现场压裂、试油验证结果一致性较好。
Hydraulic fracturing is the most effective measure to transform low porosity and permeability reservoirs.To improve the fracturing efficiency and effectiveness of low permeability oilfield and to provide target construction and accurate reservoir parameters for oil layer reform,the paper studies the low porosity and permeability reservoir in South Bohai Petroleum-Mesozoic Gubei area,upper Paleozoic sector and then explores the DSI logging data in the low porosity and low permeability reservoir evaluation and transformation.This paper also makes full use of longitudinal wave and shear wave data in combination with other conventional logging data,fracturing and testing data to establish the low porosity and low permeability reservoir rock properties and model parameters fracture prediction model for the area,which has provided a basis for the selection and design.The predicted result of this paper is consistent with the testing result.
