The reverse circulation hydraulic pump fracturing and flow integration technology is a relatively advanced technology in hydraulic fracturing operations. This technology combines the advantages of reverse circulation fracturing and flowback operations to improve efficiency and optimize the entire fracturing process. The following briefly introduces the research and application of the integrated technology: 1. Reverse circulation hydraulic pump fracturing: Reverse circulation hydraulic pump fracturing involves pumping fluid into the wellbore at high pressure to create fractures in the reservoir rock. This technology uses high-power hydraulic pumps to generate the pressure required for fracturing. The fracturing fluid is pumped into the wellbore through the casing and then flows back to the surface through the annulus outside the casing. 2. Flowback operation: After the fracturing operation is completed, flowback operation is carried out to recover the fracturing fluid and evaluate the productivity of a single well. During flowback, fluids and proppants are produced back to the surface, mobilizing the reservoir and establishing connectivity with the wellbore. 3. Integration of reverse circulation fracturing and flowback: the integrated technology seamlessly connects reverse circulation hydraulic pump fracturing and flowback operations. This approach involves optimizing the design and execution of fracturing treatments to enhance fluid recovery and well productivity during the flowback phase. 4. Research and Development: Researchers and industry experts focus on optimizing every aspect of this integrated technology.
