摘　　要：减阻水压裂液体系在北美地区致密页岩气开采中发挥着重要作用,在中国具有广阔的应用前景。建立了一套可行的室内实验方法,对减阻水压裂液体系中的主要添加剂进行了优选:通过对4种减阻剂的分散性能及减阻性能进行评价,优选出了最佳减阻剂FR-2;通过对3种表面活性剂的降低表面张力性能及对减阻剂的影响进行评价,优选出了最佳表面活性剂INTECHEM-02;通过对3种页岩抑制剂的抑制性能及对减阻剂的影响进行评价,优选出了最佳页岩抑制剂3C。此外,配伍性实验表明,优选出的3种添加剂之间以及添加剂与地层水之间均具有良好配伍性。Friction-reduced fracturing fluid system is playing an important role in compact shale gas exploitation in North America and it has a broad application prospect in China.In this paper,a set of feasible experiment method is established to optimize the main additives of friction-reduced fracturing fluid system.The optimal friction reducer FR-2 is gained through evaluation of dispersivity and friction-reducing performance of four friction reducers,the optimal surfactant INTECHEM-02 is gained through evaluation of surface-tension-reducing performance and influence on the friction reducer of three surfactants,and the optimal shale inhibitor 3C is gained through evaluation of inhibition performance and influence on the friction reducer? of three shale inhibitor.In addition,compatibility experiments show that all the three kinds of additives and formation water have good compatibility.
