Research on Intelligent Production Technology of Intermittent Gas Wells in Sulige Gas Field

Abstract

\n An intermittent gas well intelligent production technology is presented that use intelligent methods to determine and optimize the intermittent system of intermittent gas wells and use newly developed remote pressure-controlled well opening equipment that can simulate manual operations and corresponding intelligent control systems. This new approach is based on the research and application of intelligent technology in the production of intermittent gas wells. By establishing the models of gas flow in different types of gas wells, combined with the historical data of typical gas wells, the optimal pen and shut-in well time chart is finally formed. A series of remote pressure-controlled well opening equipment have been developed to replace manual pressure-controlled open well operations at the well site. Through intelligent integration of well site equipment and remote control platforms, an ntermittent gas well intelligent production management system is established. The quantitative determination of the intermittent system of different types of gas wells is realized. The effectiveness of gas well intermittent measures has increased from 72% to 90%. Electromagnetic remote-controlled open well equipment with adaptive decompression and full-open cylinder structure is developed, and can meet the requirements for rapid opening of type Il intermittent gas wells. Needle-valve type remote-controlled open well equipment embedded with intelligent well drilling algorithm is developed, and the fine well opening of class I and Il intermittent gas wells is realized. Hands-free operation is realized, and the workload of operating staff on the well site is reduced by more than 15%. On-site diagnosis of gas well production status, intelligent generation of systems, intelligent analysis and optimization are realized, and intermittent gas wells are transformed from manual management to intelligent management. An intermittent gas well intelligent production management system is established to achieve intelligent management of intermittent gas wells. Complete intermittent gas well intelligent production technology for low ermeability gas fields is described in detail to permit global similar gas field reference. The novelty of the technology lies in the use of intelligent methods to solve the production problems of intermittent gas wells, including reducing the labor intensity ofemployees, improving production efficiency, improving the fine management level of tight gas field gas wells, and reducing the impact of human activities on the natural environment.
