DSC井下仪器有氧活化和中子寿命两种测井模式,在河南油田测井近千井次。介绍了DSC仪器,展示了该仪器在中子寿命模式下识别管外窜槽、反映层内水淹、确定堵水层位以及在氧活化模式下确定遇阻深度以下吸水量或漏失量、评价油套同注分注井的注聚剖面和井下工具工作性能等方面的一些应用。
There are two types of logging modes, namely, the activation of oxygen and the life of neutron in the DSC downhole instrument. Nearly one thousand wells were drilled in Henan oilfield. This paper introduces the DSC instrument, which shows that the instrument can identify the channeling in the neutron lifetime mode, reflect the flooding in the layer, determine the water blocking layer, and determine the water absorption or the amount of water loss below the resistance resistance under the oxygen activation mode. Oil injection with the injection well injection profile section and downhole tool performance and some other aspects of the application.
