Lifecycle development and health management of water-invaded gas reservoirs:concept and practice
摘要
Abstract
Conventional gas reservoirs are the"ballasts"of natural gas production and benefits in China.However,reservoir heterogeneity and water invasion pose huge challenges to the stable production of gas wells and gas reservoirs,which makes it necessary to formulate a concept of lifecycle development and health management.Taking four typical gas reservoirs(namely Kela 2 gas field,Sebei gas field,Keshen 8 gas reservoir,and Longwangmiao gas reservoir)as examples,this paper elaborates on their geological and development characteristics,as well as the concept of lifecycle development and health management and its application in the development of various gas fields.The following results are obtained.First,based on storage and flow spaces,conventional gas reservoirs can be classified into porous,fractured,and fractured-vuggy reservoirs,which differ significantly in water invasion modes,development difficulties,and recovery factors.Second,the life cycle of a gas reservoir is divided into three stages,i.e.,water prevention during the water-free production period,water control during the early water invasion period,and water management during the middle and late water invasion periods.Third,the improvement of graded fracture description,water invasion simulation,development unit classification,collaborative and comprehensive water control technologies,and drainage gas recovery processes provides an important base and guarantee for the implementation of lifecycle development and health management and the improvement of development performance.Fourth,the practices in the four typical gas reservoirs demonstrate that the implementation of lifecycle development and health management can slow down uneven water invasion,and reduce abandonment pressure,thereby effectively prolonging the stable production period and enhancing gas recovery.In conclusion,the concept of lifecycle development and health management enables the preparation of differentiated technological countermeasures tailored specifically to porous,fractured,and fractured-vuggy conventional water-bearing gas reservoirs,providing a replicable reference for the production stabilization and improvement of domestic similar gas reservoirs.关键词
