摘要
针对页岩储层进行了大量导流试验,通过分析得到了支撑剂种类、粒径、闭合压力和铺砂浓度对页岩支撑裂缝导流能力的影响规律。同时,还研究了时间对于页岩支撑裂缝导流能力的影响。在综合考虑多种影响因素基础上,结合大量试验数据进行拟合得到计算页岩导流能力的多元回归函数式,对压裂方案设计优化和现场施工具有一定理论指导意义。
A lot of conductivity experiments were carried out for shale reservoirs,the influencing law of the type of proppant,particle size,closure pressure and sand concentration on the conductivity of shale proppant were obtained by analysis.At the same time,the influence of time on the shale proppant was studied.On the basis of comprehensively considering a variety of influential factors and in combination with a large number of experimental data,the multiple regression functional of shale fractue conductivity is obtained by function fitting.It is of theoretical significance of design and optimization of fracturing program and field practice.
