| 摘 要： | 蓬莱镇组气藏是川西北地区新场气田成组气藏中的主力气藏，加砂压裂改造储层取得重大进展。因该气藏呈现双重介质渗流特征，现有的增产效果解析数模不适宜评价其压裂增产效果。因此利用XP2井动态信息，依据达西定律、产能比和条件比，建立了新的解析数模，利用该解析数模能求取措施后理想绝对无阻流量恢复率、措施后改造净增绝对无阻流量占总净增绝对无阻流量的百分数，为增产效果评价提供了新的精细依据，且该数模评价增产效果简便，易于操作，具有推广应用价值。

| Abstract: | Gas reservoirs situated in Penglaizhen sector are major ones in northwest area, reservoir improvements make significant development by sand fracturing. Because the gas reservoir behaves double media seepage features, current analytical model are not suitable for evaluating its enhancing effects resulted from sand fracturing. Regarding such scenario, this paper establishes a novel analytical mathematical model, according to the Darcy's law, by analyzing the dynamic information from XP2 Well. The model can be used to get the ideal absolute recovery under no frictions, the ratio of absolute no-friction flux from enhancing measures to the total one. Thus, it provides novel precise information for evaluating enhancements, and is worth spreading with its simplicity. |
