Software Compilation Of Parameter Optimization For Temporary Plugging Fracturing

Low-permeability fractured sandstone reservoirs in my country are generally developed with natural fractures,but the fractures are unevenly distributed and severely heterogeneous in the vertical direction,which results in the limited utilization of conventional general transformation techniques and poor transformation effects.In the current design method of temporary plugging fracturing construction,each link is independent of each other,relying on different commercial software,and the calculation process is cumbersome.This subject is based on the predecessors,in the development and application of construction technology of fractured reservoirs,taking into account the interaction of artificial hydraulic fractures and natural fractures,comb ined with the law of temporary blocking and turning of hydraulic fractures,The technical parameter design of the process is optimized to better control and guide the application of construction technology on site.Calculate the rupture pressure by theoretical formula,give the calculation method of the rupture pressure profile along the wellbore,and compile the corresponding module;based on the criterion of the interaction of hydraulic fractures and natural fractures,give the calculation method of the b locking strength required for temporary plugging in the fracture,And compile the corresponding module;calculate the three-dimensional parameters of the crack based on the quasi-three-dimensional model and finite difference method,and compile the corresponding module;based on a large number of temporary plugging experiments and analyze the experimental data,give a temporary plugging agent formula optimization guide and determine according to the plugging depth Temporary blocking agent dosage,and compile corresponding modules.Eventually,all modules will be integrated to form an integrated proprietary software for temporary plugging steering fracturing design,simplifying on-site construction design.
