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

Gas is a nonrenewable resource,thus how to exploit gas field constantly and efficiently while maintaining maximum economic benefit is particularly concerned.Reasonable work schedule is one of key policies related to gas field economic benefit.For exploiting low-permeability gas field preferably reasonable work schedule should be made according to respective characteristics of different gas field.Changling area of Jilin gas field as the main production section with its reservoir property better,single well production higher,steady production skill stronger.By using gas resevior engineering,geological modeling,resevor simulation,several methods validate gas reserve,proper exploring speed and production scale of the area.These achievements will make scientific and proper exploring of the area.In this paper,based on Changling area of Jilin gas field,Changling gas filed is considered as a typical lithologic trapped gas reservoir,and the main reservoir of which is Denglouku,then physical property,fluid properties and pressure system of this gas reservoir are researched.In dynamic study,deliverability analysis,decline rule of production wells,deliverability estimation and well interference aree carried out;controlled reserve of gas reservoir is calculated;gas wells are prorated preliminary according to dynamic analysis;moreover,Performance of reserves and production shows,The geological model is reliable,Design and indicators can be developed on the basis of this model.
