STUDY ON PRESSURE DISTRIBUTION IN FRACTURE DURING PRODUCING PROCESS

    Graphical Abstract
    • Abstract
  • According to the mechanics of gas and oil flow in reservoir after fracturing, a pressure distribution model during producing process has been established, which consider the variation of closure pressure and fracture conductivity, and includes flow equations of formation system, flow equation of fracture system, closure pressure equation and conductivity equation. Meanwhile these equations have been iteratively solved by Alternating Direction Method and Prediction-Correction Method. Based on those work, a set of software simulating pressure distribution in fracture has been developed, which can be used to guide and emend the fracturing design, and selection of treatment material and parameters.
