Research on the Technology of Supercharging in Low Permeability Gas Field

Abstract

Pressurized exploitation is one of the important measures to ensure the continuous and efficient exploitation of gas field by reducing wellhead pressure and increasing external transportation pressure in the later period of gas field exploitation. As a typical low permeability gas field, the south area of yulin gas field has entered a decline period. The surface gathering and transportation system has been unable to adapt to the development of middle and low pressure gas reservoirs. How to carry out pressurized mining economically and effectively has become an urgent problem to be solved. In view of difficulties in gas field development, key parameters such as the timing, mode, scale and minimum wellhead pressure of pressurized gas field exploitation were studied by taking production, gathering and transportation system and economic factors into consideration. The key technology of the pressurization of low permeability gas reservoir in southern yulin gas field is formed.
