硼中子寿命测井确定剩余油分布

Determining distribution of remaining oil using boron neutron lifetime log.

硼中子寿命测井是在中子寿命测井基础上发展起来的一种适合于低矿化度地层的动态监测新技术。该技术通过暂时改变井筒附近地层水的性质 ,采用“测 -注 -测”工艺获取地层剩余油信息 ,直观解释产层的油水比例关系。根据硼中子寿命测井资料实施措施的纯 7— 10井和中 34— 2

Boron neutron lifetime log developed from neutron life is a new technology of dynamic monitoring suitable for low salinity formations. The technology can acquire the information of remaining oil in formation using “log?injection?log”technique by changing the properties of formation water near wellbore temporarily. It can guide potential tapping of measures in single wells effectively for its capacity of interpretating the relation of oil?water proportion directly. Obvious effect of oil increment is achieved in Chun 7?10 well and Zhong 34?28 well by implemented measures on the basis of boron neutron lifetime log data.
