Analysis And Research Of Northeast Sichuan Gas Reservoir Fluid

Data PVT Test Analysis is the evaluation of gas reservoir(field),gas reservoir fluid properties calculation of reserves,development plan design and gas production t echnology research important basic data.Through the study of Northeast Sichuan Laojunmiao Structural,Guangyuan structure,Heba structure of 6 wells were analyzed in 9 wellsof gas PVT experiment,obtained the gas component data,different temperature,pressure gas deviation factor,volume coefficient,compression coefficient,coefficient of thermal expansion,density data.According to the composition and properties of Northeast Sichuan basinfluid chemistry,the types of natural gas reservoirs are classified,summarized the outlet change rule of reservoir on plane and space.According to the characteristics of natural gas well in Northeast Sichuan area high sour gas,gas phase state characteristic,the natural gas reservoir sampling method and water saturation are studied.This paperstudied the variation regularity of natural gas in Northeast Sichuan high pressure physical,deviation coefficient,volume coefficient,compressioncoefficient,heat transfer coefficient,density data change rule andforecast deviation coefficient equation of expansion,improve accuracy ofequation to predict suitable area.
