Gas Producing Method Selection And Optimization Of Production Parameters

Gas producing method selection and optimization of production parameters ensure a reasonable production of gas well. The research of the gas well productivity is the basis of determining producing method and optimizing production parameters. Based on the research of gas producing method selection and optimization of production parameters at home and abroad, forecasting model of gas well productivity is optimized using field documents. Through the calculation the early test data of gas well, the binomial equation is obtained. Combined with the binomial equation and the early field data, Take the Tai 7 well for example, the parameter of gusher well is optimized. And also the sensitivity of parameters is analyzed. Liquid loading increases in the late of gas well production and an effective way to resolve liquid loading is removing liquids from gas well. Using the analysis of examples, liquid loading prediction model is comparatively analyzed, and Li Min Model is optimized. By using fuzzy evaluation method and combining with field data of Tai 7 well, artificial producing method is optimized. Using small-diameter gas pump can better enhance the production pressure and increase gas production. The parameters of small-diameter gas pump are designed, including pump selection, pumps designs, type of electric motor selection, cables selection and protection, the determination of ground surface electric voltage and control screen and voltage transformer. The impact of the gas on the electric submersible pump is studied, such as the cavitation role of gas passing components, the corrosion of hydrogen sulfide and carbon dioxide, the effects of gas impacting submersible pump characteristic parameters. The findings are significant for the rational exploitation of gas well.
