The Research On Evaluation Of Gas Well Production

Gas well production capacity is a parameter to reflect the current production capacity ofoil and gas wells, mainly changed by the reservoir geological conditions. In the gas fielddevelopment process, the accurate prediction of gas capacity and gas dynamics, andunderstanding the characteristics of gas and the shaft is the scientific basis for development ofgas fields. In the theory of the development of gas field and production practice, gasproductivity analysis is not only the main and the most common means to predict theproductivity of gas wells, analyze wells dynamic and understand the characteristics of gasreservoir, but also the most important and complex issue.Especially in new undeveloped gasfields and gas fields in the less developed, gas productivity analysis has the specialimportance.This paper described the research status about gas well production and the law ofdiminishing at home and abroad, discussed the common methods of analysis of gas wellproduction and the law of diminishing, and summarized how the analysis of gas wellproduction and the law of diminishing is important to the development of gas reservoirs. Forthe above, based on the Sichuan Basin gas wells producing energy test results of statistics, forthe development of an early rapid evaluation of gas well production can provide empiricalmethods, to meet the needs of the development plan preparation and production managementï¼›at the same time, study the low penetration of strata gas well stable capacity influencingfactors and law to provide reasonable production allocation method.
