摘要/Abstract

摘要： 为落实苏里格气田强非均质致密砂岩气藏储量规模和动用程度、评价稳产潜力，基于储层地质知识库，通过细分计算单元采用"容积法"完成储量复算；结合储层静态参数、气井生产指标及内部收益率建立了储量分类评价标准，将储量分为富集区、致密区和富水区三类；优选"单井控制面积法"评价已动用储量和剩余未动用储量。评价结果表明，苏里格气田储量基础落实，各区块储量动用程度差异大，储量综合动用程度为40.1%，剩余未动用储量规模大，稳产潜力较好。目前经济技术条件下，气田稳产主要通过井网加密、侧钻水平井及查层补孔的方式来提高富集区和致密区储量动用程度，富水区剩余储量的有效动用仍须进一步攻关。

Abstract: In order to implement the proved reserves and remaining undeveloped reserves of strong heterogeneous tight sandstone gas reservoirs in Sulige gas field and evaluate the potential of steady production, based on geological knowledge database,the reservoir was divided into several calculation units both in plane and in vertical,and the reserves of the units was also recalculated separately with volumetric method. Reserves classification and evaluation criteria were established based on reservoir static parameters,gas well production index and internal rate of return. According to the evaluation criteria,the reserves can be divided into three types:enriched area,dense area and water-rich area. And the used and remaining unused reserves were evaluated by the "single well controlled area method". The evaluation results show that there is a great difference in the degree of developed reserves among different blocks in Sulige gas field,overall the comprehensive utilization degree of reserves is 40.1%. The remaining undeveloped reserves are large in scale and have good potential for stable production. Under the current economic and technological conditions,improving reserves utilization in enriched and dense areas by through well pattern infilling,sidetracking horizontal wells and re-perforation modification of gas well are main realistic ways to stable production of gas field. Effective utilization of remaining reserves in water-rich areas still needs to be tackled further.

Key words: reserves recalculating, remaining undeveloped reserves, classified evaluation, tight sandstone gas, Sulige gas field
