化学剂对磷酸酯类油基冻胶压裂液性能的影响

Influences of Crosslinking Agents on the Properties of Dieselbase Gel Fracturing Fluids

系统研究了 9种化学剂对柴油基冻胶压裂液性能的影响 ,结果发现 :在一定剪切速率(1 70s- 1)下 ,添加不同类型的化学剂对柴油基冻胶压裂液的性能影响很大 ,其中化学剂Z 1和Z 7可以显著提高柴油基冻胶压裂液的抗温和抗剪切性能 ,使得剪切后的压裂液粘度较不加化学剂提高了近 1 0 0mPa .s.

The influences of 9 crosslinking agents on the properties of a dieselbase gel fracturing fluid are studied by means of experiments. It is shown that at the shear rate of 17s -1 ,the influences of different crosslinking agents are different, the differences are great, the crosslinking agents of Z1 and Z7 can greatly increase the temperaturerisisting and shearresisting abilities of the fracturing fluid, the viscosity of the fracturing fluid after being sheared is increased by about 100 mPa.s.
