| Abstract:Hydraulic fracturing is an important technology to improve production in low permeability reservoir, the performance of the fracturing fluid is also a key factor , which affect the increasing production of hydraulic fracturing. Fine quality ,high efficiency show the developing trend of blending technology. Based on the analysis of both the current technology problems of fracturing fluid blending and characteristics of thickening agent and solid additive,the key factor that limits the efficiency of fracturing fluid blending is pointed out ,and a new blending technology of fracturing fluid that promote dissolution rate and quality of fluid is put forward according to experimental research. By means of PLC, the fracturing fluid is blended automatically. The new blending technology and equipments have been applied in Daqing oilfield for more than two years. Practical application result demonstrates that the new technology possess characteristics, such as viscosity release quickly, accurate additive adding, all kinds of additive are mixed evenly, the dry power surround by water is eliminated in guar solution. The validity and reasonableness of the new technology is verified. |
