Practice of fine injection-production in offshore oilfield based on information integration
Fine injection production supported by oilfield development information integration technology is an effective means to tap potential and increase production.Aiming at the injection-production contradiction and complex development situation faced by the development of offshore L Oilfield,a three-dimensional information model of complex multi-layer reservoir was constructed according to the idea of standardized integration.Five kinds of data,including drilling,logging,completion,testing and production-injection,were integrated into the wellbore model with well trajectory coordinate points as the carrier,and three kinds of knowledge information,including structure,geology and reservoir research results,were integrated into the reservoir model with reservoir coordinate points as the carrier.The intelligent matching of wellbore model information and reservoir model information was realized by using node connection.By embedding the objective function,calling and calculating the integrated information and visual analysis,the above model could complete the fine analysis of injection-production performance and index prediction of multi-layer complex oilfields.The practice in L Oilfield showed that this technology could effectively guide the optimization of stimulation measures and development plans,and help improve the level of oilfield development decision-making.
