STUDY AND APPLICATION OF PSEUDO-THREE-DIMENSIONAL ACID-FRACTURING DESIGN SOFTWARE

The pseudo-three-dimensional mathematical models for dynamic fracture propagation,acid-rock reaction,temperature field of wellbore and fracture are established and the relevant software is developed,which can be used to calculate the parameters such as variation on dynamic fracture propagation,acid corrosion fracture length and conductivity,production stimulation multiple etc.,and to output data and curves of the calculated parameters with the variation of fluid injection time.This software is suitable for operation design,simulation computation and sensitivity analysis of parameters.It has a guiding significance for the theoretical study on the fracture propagation and acid-rock reaction mechanism.This software wins the award of production engineering excellent software by Development Bureau of CNPC and the second award of science and technology by RIPED of CNPC.
