老气田的储层参数差异较大,无法根据单个指标评估整个区块的开发潜力.为此,重新构建老气田开发潜力评价指标体系,从储层物性、储量规模及动用情况、生产动态、地层情况等方面对其开发潜力展开综合评价.以四川盆地气藏为例,从 12 个区块资料中筛选出 12 项相关开发评价指标,利用灰色关联分析法对这些区块的开发潜力进行综合评价及优选排序.经评价和优选,将老气田划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ类潜力区块,其中开发潜力较大的Ⅰ类、Ⅱ类区块主要包括LHC、TSN、HLC、WQJ等4 个区块.此评价结果可作为针对老气田潜力区块进行优选的理论依据.
Evaluation of Development Potential of Old Gas Fields Based on Grey Correlation Analysis——A Case Study of Gas Reservoirs in Sichuan Basin
The reservoir parameters of old gas fields vary greatly,and a single indicator cannot represent the devel-opment potential of the entire block.To this end,a new evaluation index system for the development potential of old gas fields is constructed,and a comprehensive evaluation of their development potential is carried out from the aspects of reservoir properties,reserve scale and utilization,production dynamics,and geological conditions.Tak-ing the Sichuan Basin gas reservoir as an example,12 relevant development evaluation indexes were selected from the data of 12 blocks,and the grey correlation analysis method was used to comprehensively evaluate and optimize the sequencing of development potential of these blocks.After evaluation and optimization,the old gas field is di-vided into potential blocks of Class I,II,III,and IV.Among them,Class I and II blocks with higher development potential mainly include four blocks:LHC,TSN,HLC,WQJ,etc.This evaluation result can serve as a theoretical basis for optimizing potential blocks in old gas fields.
