Design and Application of Gas Lift Measures in Xihu Gas Field,East China Sea
In view of problems of serious effusion or water flooding after water breakthrough and stable production in the wells of Xihu water drive gas reservoir in the East China Sea,combined with the characteristics of water production in gas wells,the gas lift is studied.Through the establishment of typical well pipe flow model,the parameters such as gas injection,gas lift valve are optimized,and the scientific and rapid selection of gas lift parameters is realized.On the basis of gas lift design,the proces-ses of conventional gas lift,perforated gas lift and nitrogen gas lift are optimized and applied,and the matching process of gas lift measures suitable for gas wells in the West Lake of the East China Sea is formed,which provides a certain reference for the drainage and gas recovery measures of subsequent oil and gas reservoir mining.
