摘要/Abstract

摘要： 针对川中磨溪气田开发中后期气井复产增产需求迫切、亟需采气工艺效果评价方法的问题,建立了川中磨溪气田采气工艺措施效果评价方法,实现了对采气工艺实施效果的综合定量评价。该方法选取措施实施前后的最大井口产能增幅、累计增产气量比例、累计增产水量比例及工艺有效期作为定量评价指标,并明确各指标权重;采用模糊层次分析法将多类评价指标融合为采气工艺综合评价指标,综合指标数值越高,表明对应采气工艺实施效果越优。将所建评价方法应用于川中磨溪气田60口生产井,完成了其采气工艺措施效果的实际评价。结果表明:磨溪气田中部气井采气工艺效果整体较好,东西两侧部分气井效果一般,低产井应用效果总体较差,高产井应用效果相对较好,采气工艺实施前后井口最大产能增长比例与采气工艺综合指标I成正相关,工艺有效期大于50 d的气井工艺效果更优。研究内容对完善国内外气井采气工艺效果评价体系、支撑气田高效开发与可持续稳产具有重要的理论参考与实践指导意义。

Abstract: In the middle and late stages of development of the Moxi Gas Field in central Sichuan,there is an urgent need for gas wells to restore and enhance production,and consequently an evaluation method for the effectiveness of gas production engineering measures is required.To solve this problem,an evaluation method for gas production engineering measures in the Moxi Gas Field was established,enabling comprehensive quantitative evaluation of the implementation effect of such measures.This method selects the increase in maximum wellhead deliverability,the proportion of cumulative incremental gas production,the proportion of cumulative incremental water production,and the effective period of the engineering measure before and after implementation as quantitative evaluation indices,and determines the weight of each index.The fuzzy analytic hierarchy process was used to integrate multiple categories of evaluation indices into a comprehensive evaluation index for gas production engineering measures.A higher value of the comprehensive index indicates a better implementation effect of the corresponding gas production technology.The proposed method was applied to 60 producing wells in the Moxi Gas Field,and practical evaluation of the effectiveness of gas production engineering measures was completed.The results show that the overall effect of gas production engineering measures is relatively good for wells in the central part of the Moxi Gas Field,whereas the effect is moderate for some wells on the eastern and western flanks.The overall effect is relatively poor in low-productivity wells but comparatively good in high-productivity wells.The growth ratio of maximum wellhead deliverability before and after implementation is positively correlated with the comprehensive engineering index I,and gas wells with an effective period longer than 50 d exhibit better engineering performance.This work provides important theoretical reference and practical guidance for improving the evaluation system of gas production engineering measures for gas wells and for supporting efficient development and sustainable stable production of gas fields.

Key words: evaluation of gas production engineering effectiveness, growth ratio of wellhead deliverability, effective period of engineering measure, fuzzy analytic hierarchy process, Moxi Gas Field in central Sichuan Basin
