气藏动储量评价方法研究

气藏中可流动天然气的总量就是气藏动储量,它可以将气藏的动态特征充分的展现出来,从而更好地为地质储量起到贡献作用。从现阶段的研究情况来看,主要的气藏动储量的研究方式主要有压降法、弹性二相法、压力恢复法、产量递减法和数值模拟法等等。就根据目前国内外储量的评价方法进行了深入的研究,并在此技术上根据气藏特征变化参数建立了新的储量计算方式,希望可以为气藏的高效开发提供一定的理论依据。

Study on evaluation method of gas reservoir dynamic reserves

the total amount of flowable natural gas in the gas reservoir is the dynamic reserve of the gas reservoir, which can fully show the dynamic characteristics of the gas reservoir, so as to better contribute to the geological reserve. From the current research situation, the main research methods of gas reservoir dynamic reserves mainly include pressure drop method, elastic two-phase method, pressure recovery method, production decline method and numerical simulation method. In this paper, according to the evaluation methods of reserves at home and abroad, a new reserve calculation method is established based on the change parameters of gas reservoir characteristics, hoping to provide a theoretical basis for the efficient development of gas reservoir.
