Study On Capacity Evaluation And Rational Distribution Of Shantou Area Of Jingbian Gas Field

Shaanxi 330 well area is the key area of Jingbian gas field expansion.At present,the production characteristics and reasonable distribution of gas wells in this area are not clear,which leads to the rapid decline of gas production in the process of mining and the low degree of recovery,The development of the whole and long-term development,in order to improve the production status of gas and new and old well production forecast and distribution to provide reliable recommendations,the need for capacity evaluation and production research.Based on the analysis and summarization of reservoir characteristics,fluid properties and seepage characteristics in the study area,this paper first studies the practicality of calculating the dynamic reserves method,and based on the advantages and disadvantages of each method,The existing data and production conditions,selected the method suitable for this area,through the calculation and then get the study area of gas wells dynamic reserves;then the use of conventional methods for gas well productivity evaluation,for the particularity of low permeability gas reservoir,the use of dynamic capacity evaluation method The gas well production capacity calculation,and analysis of key factors affecting gas production capacity,aimed at improving the accuracy of gas well production capacity evaluation.On the basis of the production principle,based on the analysis of capacity and the analysis of dynamic reserves,the production of gas wells is optimized on the basis of taking full advantage of the formation energy and taking into account the stable production period of the gas well control dynamic reserves.Combining with the optimization results,Gas wells are classified to determine the reasonable distribution of each grade gas wells,which provides theoretical and practical suggestions for optimizing the distribution of new and old wells in the later stage.
