Abstract

The invention belongs to the technical field of fracturing fluid addition, and discloses a fracturing construction real-time water quality automatic online viscosity adjusting system and method, and the system comprises a central control unit, and a water quality monitoring unit, a viscosity monitoring unit and a fluid addition control unit which are respectively connected with the central control unit; the water quality monitoring unit is used for monitoring the water quality condition of liquid in a stirring tank of a fracturing blender truck and sending detected water quality detection data to the central control unit in real time; the viscosity monitoring unit is used for monitoring the viscosity condition of liquid in the stirring tank of the fracturing blender truck and sending detected viscosity data to the central control unit in real time; the liquid adding control unit comprises a conveying mechanism which communicates between an agent box and the stirring tank of the fracturing blender truck; and according to the received water quality detection data and viscosity data, the central control unit adjusts the filling condition of the filling pipe for filling chemicals into the stirring tank of the fracturing blender truck through the liquid adding control unit. The viscosity of the construction liquid can be accurately adjusted in real time.

Description

technical field [0001] The invention relates to the technical field of fracturing fluid addition, in particular to a system and method for automatically adjusting viscosity on-line in real time during fracturing construction. Background technique [0002] In the field of oil and gas reservoir stimulation, fracturing refers to a method of using hydraulic action to form fractures in oil and gas layers during the process of oil or gas recovery. Fracturing artificially creates fractures in the formation, improves the flow environment of oil underground, increases the production of oil wells, and plays an important role in improving the flow conditions at the bottom of the oil well, slowing down interlayers and improving the production status of oil layers. [0003] Fracturing fluid is the working fluid in the fracturing process, which mainly plays the role of reducing friction, transmitting pressure and carrying proppant during the fracturing process. Therefore, the performance...
