室内支撑剂导流能力测试能定性认识支撑剂导流能力，对现场压裂支撑剂优选具有重要的指导意义。目前，支撑剂导流能力评价多依据单相（水相或油相）导流能力测试结果，评价结果对现场指导性有着一定的局限。运用FCES-1裂缝导流仪对三种疏水支撑剂的水相、油相及两相导流能力进行了实验研究。首先通过对比疏水支撑剂与普通陶粒的单相导流实验结果，对各疏水支撑剂的疏水性能进行分析评价。随后，配置具有现场类比性的模拟乳化液对不同铺砂浓度条件（5 kg／m2、10 kg／m2）的疏水支撑剂两相导流能力进行测试分析。实验结果表明，随着闭合压力的增加，各支撑剂导流能力均逐步降低；随铺砂浓度的增加而略有增加。同时，疏水支撑剂的油相导流能力大于水相导流能力，并且由于乳化液的堵塞作用，单相导流能力均大于两相导流能力。

Laboratory tests were conducted to evaluate the proppant pack conductivity qualitatively, which is in-structive in field optimization of fracturing proppants.At present, the evaluation of proppant conductivity is usually based on the experiment results for single-phase flow, which has a certain limitations for on-site guidance.Conduc-tivity about three kinds of hydrophobic proppants were tested by FCES—1 ( fracture conductivity evaluation system) for both water、oil and two-phase flow.At first, experiment result of the hydrophobic proppants conductivity for sin-gle-phase flow were compared with ceramicite to evaluate the hydrophobic properties.Then, the field compared simulation emulsion was applied in two phase flow conductivity experiment for the hydrophobic proppants and the results were analyzed,while the paved-sand content was varied as 5 kg/m2 and 10 kg/m2.The experimental results indicated that conductivity of proppants would decrease along with the increasing of pressure and increase when the paved-sand content was raised.Meanwhile, the hydrophobic proppant conductivity for oil phase was greater than conductivity for water.In addition, conductivity for two-phase flow is also much greater than conductivity for single-phase flow because of the blocking caused by sticky simulation emulsion.
