放磁技术在浅层气挖潜中的应用

Application of magnetic release in shallow gas potential tapping

运用中子伽马测井和中子寿命测井技术,分析了储层孔隙中含不同流体时的测井曲线响应特征,利用老井新旧中子伽马测井和中子寿命测井资料的差异,对浅层气进行了系统的研究。通过研究认为,辽河盆地具备形成浅层气的优越条件,发现了多个有认识价值的勘探目标;形成了一套浅层气滚动勘探的综合技术,为辽河油田天然气产能建设做出了一定的贡献,对浅层气的挖潜具有一定的指导作用。

Log responses of reservoirs containing different fluids are analyzed by using neutron gamma logging and neutron lifetime log.Shallow gas is systematically studied by the difference between old and new data of neutron gamma logging and neutron lifetime log.The study indicates that Liaohe Basin possesses favorable conditions of shallow gas and several exploration targets are identified.A series of exploration technology for shallow gas exploration has been formed.This makes a contribution to gas production capacity construction in Liaohe Oilfield and is of guiding significance to shallow gas production.
