| Description | Journal: Iop Conference Series: Materials Science and Engineering Hydraulic fracturing is an important measure and main method for increasing production of coal reservoir. As one of the key materials of hydraulic fracturing, fracturing fluid directly determines the production of wells and greatly affects economic benefits. According to the requirement of fracturing fluid for large inclined coal seam, the low viscosity active water fracturing fluid was used in the early stage of fracturing, and the high viscosity clean fracturing fluid was used in fracturing and sand adding, thus forming a complex fracturing fluid system. After field construction application, the entering fluid and the operating pressure of the complex fracturing fluid system are lower than those of the active water fracturing fluid well, that shows that the compound fracturing fluid has many advantages, such as high fracture efficiency, strong sand carrying performance, small friction coefficient and high success rate. The desorption pressure, average gas production, bottom hole flow pressure and the highest gas yield of wells operated with compound fracturing fluid are all higher than those of wells operated with active water fracturing fluid, which shows good potential for high yield. |
