Abstract: The determination of characteristic parameters of hydraulic fracturing in-situ stress measurement is very important to improve the accuracy of measurement results. In order to avoid personnel errors and repeating operations due to manual processing of recording data, one software was developed to define the stress measurement parameters of hydraulic fracturing recording curve automatically by computers. This interactive software includes three modules: data acquisition, data processing and database management. The core is the data processing module, which include all the methods for the determination of stress measurement parameters, Pr and Ps. This software was realized using VB development platform, with friendly interfaces and reliable functions. The application in the stress measurement campaigns in a borehole in Honghe town, Weifang City, Shandong Province proves the reliability and convenience of the software.
