摘要

基于中国32个不同类型已投入开发大型气田600余口井的生产动态数据,建立了以气田为单元的井均动态储量与井均初始无阻流量关系图版,并通过理论推导探讨了二者关联性的内涵与图版的应用范围。研究表明：中国大型气田井均动态储量与井均初始无阻流量在双对数坐标系中呈高度线性正相关,其相关性体现了中国大型气田在规模、效益和稳产开发模式下,通过优化设计建立的动态储量与初始无阻流量之间的匹配关系,亦即产能与稳产能力之间的匹配关系。图版具有普遍适用性,可用于估算气田开发初期达到生产规模、稳产年限要求所应具备的合理井均动态储量,为确定气田开发技术指标提供快速、有效的方法;同时,也可用于对比评价已开发气田的开发效果和加密潜力。图6表3参23

Abstract

Based on performance data of over 600 wells in 32 large gas fields of different types in China, the correlation is established between per-well average dynamic reserves ($\bar{G}$) and average initial absolute open flow potential (${{\bar{q}}_{\text{IAOF}}}$) of each field, and its connotation and applicability are further discussed through theoretical deduction. In log-log plot, $\bar{G}$vs. ${{\bar{q}}_{\text{IAOF}}}$exhibit highly dependent linear trend, which implicates the compatibility between $\bar{G}$ and ${{\bar{q}}_{\text{IAOF}}}$ attained through development optimization to reach the balance among annual flow capacity, maximum profits and certain production plateau, that is to match productivity with rate maintenance capacity. The correlation can be used as analogue in new gas field development planning to evaluate the minimum dynamic reserves which meet the requirement of stable and profitable production, and facilitate well pattern arrangement. It can also serve as criteria to appraise the effectiveness and infill drilling potential of well patterns for developed gas fields.

Key words： large gas fields in China; initial AOFP; dynamic reserves; type curve; infill drilling potential
