Research On The Control System Of Oil Extraction Joint Station Based On PLC

With the discovery of Qingshen gas field, Daqing Oilfield to implement the gas fill oil strategy, and gradually increased efforts to develop natural gas, Found in the mining process,the physical characteristics of sediments from different years vary, most gas production wells are to take office under the jurisdiction of a single layer pre-development, post-fill hole fracturing is developed. However, some gas wells in the late fill hole fracturing did not achieve the desired results. So the study points multilayer gas reservoir, affecting co-development efficiency and different production methods for gas production has far-reaching significance.Based on preliminary geological research knowledge on the use of well- modeling and seismic establish Qingshen gas reservoir three-dimensional structural model; in the structural model framework, full use of vertical resolution controlled logging data to measure well information as the basis, the basis of geological knowledge, analysis of reservoir property characteristics, using multiple information modeling constraints, combined with the understanding of air-water interface, to carry out three-dimensional modeling gas reservoirs and reservoir properties of the fluid distribution; according to Xu data with the 1 block deep gas well deliverability analysis, calculate the unimpeded flow, the use of test mining, gas test data, test mining, gas test interpretation to give its reservoir model; combining dynamic reservoir models and production data for the production of dynamic forecasts and analysis of the feasibility of its mining division, according to the last feature extraction wells to obtain different principles reservoir mining division, and calculate an interlayer between the layers when commingled interference factor.
