High-low Pressure Gas Mixed Transporting Technology for Pressurization Period of Gas Gathering Station in Daniudi Gas Field
As the pressure of gas wells in Daniudi Gas Field decreases,the gas field has implemen-ted the first station centralized pressurization and single station pressurization step by step,and the gas field has entered the low-pressure production stage as a whole.During the new production capac-ity of the gas field,the pressure of new and old wells cannot be effectively matched,and some gas gathering stations have no remaining interfaces.In view of the above problems,the adaptability of the gathering and transmission system need to be further improved.Based on original single well high-pressure gas gathering process in Daniudi Gas Field,this paper has optimized the mixed gas gathering mode with the feature of"high-pressure gas gathering"+"downhole throttling,nearby series connection,low-pressure gas gathering,and mixed transmission pressurization".The mixed gas gathering mode can meet gas gathering demand of Daniudi Gas Gathering Station during the pres-surization period,which significantly reduces the investment in single well pipeline and improves the production efficiency of gas field.
