岩屑自然伽玛放射性录井方法可行性研究

Research on Fine Cuttings' Nature Gamma Radio Logging Method Possibility

在油气的勘探开发过程中,地质录井方法作为实时跟踪钻进过程,及时获取地层岩性及其地层流体信息的重要手段,具有不可替代的作用。但是随着钻井新工艺的快速发展和应用,使得地层的岩性在录井现场已难以判断,造成传统的录井方法已难以适应现场施工要求。该文提出了一种能够应对这种挑战的录井方法——岩屑自然伽玛放射性录井方法。文中介绍了该录井方法的理论依据,还通过大量的试验对该录井方法的可行性进行了验证,并得出该方法切实可行的明确结论。

In the wake of fresh technology of well drilling fast development and application, the layer crag in living logging field is difficultly judged, this lets the tradition logging means difficultly adapt to the building demand at field. It proposes the well logging means of the natural gamma radioactivity of fine cuttings, and introduces its theory foundation. The eperiment by means of greats quantity has been done, moreover the conclusion making that means in practicable has been got.
