Abstract
Fracturing and acidification are widely used as stimulation methods in conventional and unconventional fields. After the fracturing fluid or acid enters the formation, the fracturing fluid or acid enters the flowback reservoir through the wellbore and flowback line. To prevent contamination, flowback fluids are usually treated for fracturing or acidizing in adjacent Wells or discharged after meeting discharge standards. In the process of flowback, the performance and parameters of flowback fluid can reflect the effect of fracturing or acidification and guide the recovery and reuse of flowback fluid. Sand content, breaking properties (viscosity), density, PH, flow rate, salinity, acidity, and other solids and residue content are the most important parameters for engineers to focus on. These parameters are usually obtained in the field by sampling from a flowback pool or other location. The data error obtained by this method is large, and the monitoring index is not comprehensive, systematic and continuous. Aiming at this phenomenon, the author developed a set of real-time monitoring system for fracturing and acidizing flowback fluid, which can calculate and analyze the parameters of flowback fluid in real time. The research results show that the device can obtain the parameters of fracturing or acidizing flowback fluid in real time and continuously, improve the accuracy of monitoring data of parameters of flowback fluid, reduce labor intensity, and promote the informatization and intelligent construction of fracturing and acidizing field.
