[Abstract]:The application and research of Sanshen gas field are mainly aimed at the production status of weak water drive gas reservoir in this gas field, its edge water is not active, and its production mainly depends on gas drive. In order to develop the gas field well and achieve the aim of taking measures according to the local conditions, a targeted development policy is adopted. Due to the difference of the gas wells' own conditions and production conditions, how to select and determine the foam drainage system, The application of optimal string technology is the main means of drainage and gas recovery in the early stage of gas field. In the middle and late stage of the gas field development at three stations, the drainage effect will become worse or invalid. It is imperative to select and apply new drainage gas production technology. The research on plunger drainage gas production technology and eddy current drainage gas production technology is carried out. It is used as the technical reserve of drainage gas production in gas field. In the middle and late stage of development of Sanshang gas field, with the decrease of the number of new wells put into production, how to improve and excavate the productivity of old wells and become an important means of increasing production rate. It provides a reference and basis for the follow-up measures of the old well in the gas field. For a horizontal well in Sanzhou-gas field, the design productivity is not reached after putting into production. Well skin coefficient data show reservoir pollution, acid plugging test is carried out to improve oil recovery. It is expected to adopt step by step skidding sleeve stage acidizing process string to carry on the test. After the test, the reservoir pollution can be reduced and the gas production rate will be increased. The purpose of improving oil recovery is achieved. At the same time, the application of acidified tubing string in horizontal gas wells is evaluated. This subject mainly aims at the actual situation of the three stations gas fields, selects the reasonable classification of some gas wells in the three stations gas fields, and implements the productivity of the gas wells in this area on the basis of the classification. The characteristics of water production in gas wells are analyzed and a reasonable bubble discharge system is established. In this paper, 10 new gas wells are selected from three stations gas field, and the optimum selection of tubing string is carried out, and the reasonable production system is determined. In addition, through the statistical study of gas well production, two representative test wells are selected to carry out plunger lift test. According to the principle of eddy current drainage, one test well is selected. The hole filling measures are carried out in an old well, and its effect is followed up and analyzed. The horizontal well acidizing measures are carried out to solve the pollution in the near well zone, and its effect is followed up and analyzed. I have been engaged in and participated in the research and application of gas well drainage gas recovery and measures, and accumulated rich experience from it, which lays a good technical foundation for the completion of the analysis and research on the high efficiency development of three stations gas fields.
