Products>>Project Development>>Research and Software Development of Long-Term Production Data Analysis Method for Fracture-Vuggy Reservoir

The base theory of production data analysis based on variable flow rate and pressure seepage mechanics theory, put forward the seepage mechanics equation satisfied the requirements of engineering precision, and introduce certain assumptions to simplify and solve the equation is the key. At present, both domestic and foreign havn’t mature analysis and research methods for fracture-vuggy reservoir production data. With the development of the fracture-vuggy reservoir, there is an urgent need for relevant professional software to explain and analyze the daily production data without affecting the production.

This project is based on the flow-fluctuate coupling model, based on which the variable flow and pressure production data analysis model and interpretation method are proposed.

Research on production data analysis model of fracture-vuggy reservoir: flow model of fracture-vuggy reservoir; characteristic model of flow-fluctuate coupling; production data analysis model of variable pressure and flow are built.

Research on analysis method for production data in fracture-vuggy reservoir: definition of dimensionless parameters and establishment of dimensionless equation for production data analysis in fracture-vuggy reservoir; Solution of mathematical equation for production data analysis in fracture-vuggy reservoir: Laplace transformation of dimensionless equation and solution in Laplace space, theoretical solution for dimensionless bottom-hole pressure is obtained; Research on fracture-vuggy reservoir typical curve plate and production data analysis method: according to the theoretical solution of dimensionless bottom-hole pressure, plot the typical curve plate in log-log coordinate system and suggest the analysis method of fracture-vuggy reservoir production data analysis.

R&D of production analysis software for fracture-vuggy reservoir production; programming data analysis software for fracture-vuggy reservoir production, integrating and testing data analysis software for fracture-vuggy reservoir production.

At present, there is no mature production data analysis method in domestic and foreign, and the existing production data analysis software also does not have a special production data analysis model of fracture-vuggy reservoir. Our company research the fracture-vuggy reservoir, put forward analysis method of production data analysis and the concept of accumulated time, the accumulated time can replace the material balance time and solve the problem that x axis does not coordinate. At the same time, according to existing problem of frequent shut in and open well in production process. the concept based on the virtual equivalent time is put forward, the simulation quality is greatly improved, and reasonable simulation results and future capacity prediction are given.
