| The Lower Paleozoic gas reservoir in jingbian gas field is a carbonate gas reservoir with low porosity,low permeability and low abundance.After 30 years of development,it has entered the final stage of natural stable production with low reservoir producing degree.As the main area of jingbian gas field,the change of production situation in Shan45 well area can reflect the production status of jingbian gas field.At present,the well patterns in some low permeability areas are not perfect,and the producing degree of secondary production layers are poor.Therefore,it’s necessary to evaluate the reservoir development potential,calculate the remaining recoverable reserves of each layer,and put forward effective reservoir development methods for the next step exploration of jingbian gas field.This paper firstly analyzed and summaried the structure,sedimentary,reservoir characteristics,fluid and temperature characteristics of the gas field,and established a three-dimensional geological model.Then,the results of gas well static dynamic data and gas production profile tests were used to study the production dynamics of gas reservoir and calculate the gas production of each layer.After that,this paper calculated the remaining recoverable reserves of each layer and analyzed the reservoir development potential.Finally,the paper carried out the research on reservoir development technology,put forward four effective methods to develop the gas field and forecasted their effect by the numerical simulation method. |
