Stabilized Production Study of a Low Permeability Gas Reservoir in West

Stabilized production study of gas field is important for producing gas field scientifically.EOR in stable production period effects ultimate recovery.This article determines in quantify influence order and influence degree of gas production rate per day per well,gas production rate and reserves producing degree respectively to EOR in stable production period using principles and thoughts of orthogonal test taking a gas field west as an example according to intuitive analysis,variance analysis and contribution rate of factors analysis respectively,which provides a basis for development program of this gas field.At the same time,contribution rate of factors analysis in this paper can solve problem that many indicators of test are not subject to normal distribution in the development of oil and gas fields
