胜利油田浅层气藏合理产量分析

Analysis of Reasonable Production of Shallow Gas Reservoirs in Shengli Oilfield

胜利油田浅层气藏具有高孔高渗、胶结疏松、边底水发育的特点,在开发过程中,气井易出水、出砂,稳产期短,产量递减快.选择合理的气井工作制度是气藏开发方式的重要内容,而确定气井的合理产量可以充分利用气藏天然能量,使气藏保持较长的无水采气期,有效提高气藏采收率.

The shallow gas reservoirs of Shengli Oilfield has such characteristics as high porosity and permeability,toss cementation and development of bottom water. As the shallow gas wells are subject to effluent water and sand while being exploited and have a short period of stable production and low output,it is the key to the development of a shallow gas reservoir to choose a reasonable working system of gas wells.Defining the reasonable production can make the most use of natural energy of a gas reservoir, which enables the gas reservoir to have a longer anhydrous gas recovery period and considerably improve the recovery rate.
