The Pattern Of Formation Water And Restoring-production-measure Optimization Of Water-producing Gas Wells In Jingbian Gas Field

In the accumulation processes of Jingbian Gas Field, because the differentiation of gas and water is not completely finished, the water in gas field is distributed intricately. And with the large-scale development of Jingbian Gas Field,formation pressure continues to reduce, water production wells and water production gradually increase and some of the water-production gas wells, which have poor Liquid carrying capacity, cause serious Wellbore liquid and stop production, so the balanced development of the gas reservoir is effected seriously.Based on the research on the existing water layer recognitional method, combined with the dynamic production data, gas testing data and so on, water production layer is identified of south No.2and north No.2in main water production areas. At the same time, combined with reservoir fracture, high permeability zone and also other physical property characteristics, relative water-abudanct areas of south No.2and north No.2in the gas field are classifyed. Finally, unloading restoring production measures of the shutdown well are cariied out pertinently whic recover the production of the shutdown well timely and maintain the productivity and efficient development of gas wells.
