The Numerical Simulation of the Pressure Pulse Plugging Technology in Pressure Shocks Field

Abstract:

In the oil field development process, oil wells production capacity has been severely affected by clogged wells. There are many ways to relieve clogged wells, due to easy to operate, on the lifting of the blockage formation, the pressure pulse plugging technology has good prospects, but the current theory remains to be further studied, so the pressure pulse plugging process was simulated necessarily. The task to pressure pulses pulse tube plugging device as the research object, the establishment of its three-dimensional structure model to study the internal structure of the chamber, to analyze the impact of the flow field structure size rule. Establish its simplified model two-dimensional flow field, the compiler can achieve the state of motion of the sphere device UDF, application dynamic mesh of the pulse tube through Fluent unsteady flow was simulated. By convection field pressure, velocity and import-sectional physical monitoring equipment installation depth research and analysis, work flow, pressure relief device structure and the formation process of the pressure shocks field were investigated. Reveal the pulse tube working mechanism, and promote understanding of the pressure pulse plugging the nature of technology, optimize the structure of the pulse tube design basis and direction for the pressure pulse plugging technology and its theoretical foundation dynamics simulations.
