摘　　要：大庆油田外围陆续发现了汪家屯、三站等多因素控制的特低渗透复合型气藏 ,储量占已探明气田地质储量的 5 0 %。然而 ,随着这些气田的相继开发 ,其井控储量、可采储量、产能等与勘探时期相差较大 ,暴露出了评价勘探阶段对气藏认识程度和储量计算精度方面存在一些问题。文章从解剖有代表性的汪家屯、三站气田入手 ,通过对气田的地质精细研究 ,总结出一套适合这类气田开发和储量计算的方法 ,对大庆油田已探明的中浅层气田的资源潜力进行了研究 ,为今后评价和计算这类气田的储量提供了借鉴经验。Some complex gas reservoirs with extra-low permeability, such as Wangjiatun and Sanzhan, etc. controlled by many factors have been continuously found in the skirts of Daqing oil field. Their reserves have accounted for 50% of the total proved reserves of all gas fields. As the gas fields are put into production one by one, it is found that the well-controlled reserves, the recoverable reserves and the productivities are quite different from those calculated during exploration, which shows the defects on the understanding level for the gas reservoirs and the calculating accuracy for the reserves during the stage of appraisal exploration. Taking the representative gas fields of Wngjiatun and Sanzhan as example, with fine geological study for the gas fields, the article proposes a set of methods suitable to the development and reserve calculation for this kind of gas fields. With the methods, the resource potential of the proved gas fields with medium and shallow depth is reviewed in Daqing oil field. It provides reference to evaluate and calculate the reserves of this kind of gas fields in future.
