Interpretation Study Of Well Testing Data In KLML Gas Field

The Kelameili gas field isthe first production of 100 billion cubic meters of gas field in The Junggar Basin. According to the theory of PercolationMechanics,Because of the complex geological reservoir conditions and the severity heterogeneity.geological conditions,choosing a suitable mathematical model of well test interpretation for The Kelameili gas field.Through the gas field testing data analysis and research,the main contents are as follows:(1) Established and solved the homogeneous gas reservoir well test interpretation mathematical model considering wellbore storage,skin factor,stress sensitivity and wellbore phase redistribution,and drawn the well test interpretation mathematical modeling of flow characteristic curve and analyzed its influential parameters;(2) Established and solved the dual media gas reservoir well test interpretation mathematical model considering wellborestorage,skin factor,stress sensitivity and wellbore phase redistribution,and drawn the well test interpretation Mathematical modeling of flow characteristic curve and analyzes the influencing factors,such as storativity coefficient and channeling coefficient;(3) The establishment of an infinite boundary homogeneous gas reservoir infinite conductivity vertical fracture well test interpretation mathematical models,taken the Stehfest numerical inversion method to obtain analytical solution of inverse Laplace space into real space bottom hole pressure solution,and drawn the well test interpretation mathematical modeling of flow characteristic curve and analyzed its influential parameters;(4) Establishde and solved an infinite boundary homogeneous gas reservoir finite conductivity vertical fracture well test interpretation mathematical model,drawn the well test interpretation Mathematical modeling of flow characteristic curve and analyzed its fracture flow characteristics and the impaction of fracture conductivity;(5) In theory the results of the model as a guide,chose the corresponding mathematical model of well test interpretationwere fit to explain the gas field pressure build-up test data to obtain reservoir parameters.According to the gas well test data interpretation, thewellbore phase redistribution characteristics,Stress sensitivity,the influence of the different gas boundaries,edge and bottom water intrusion situation were analyzedthe testdata and research work for the site to provide practical application and production technical support.
