MIT/MTT与SBT组合测井在安塞油田的应用

The application of MIT/MTT and SBT combined logging in Ansai Oilfield

油田经过长期开发,油水井套管在外力和化学腐蚀的作用下出现不同程度机械损伤和腐蚀,直接影响油水井的使用寿命,从而严重影响开发方案的实施,难以满足油田稳产上产的需求。本文从原理和油田应用实例分析两个方面介绍了MIT/MTT与SBT组合测井在套损检测和固井质量评价方面的适应性,为油田下一步综合治理提供更好的技术支持。

After long time of developing, the oil well casing has different degree ofmechanical damage and corrosion under the external and chemical force which directly determines the service life of the oil well casing. It affects the implementation of the developing plan and fails to feed the oilfield’s needs of sustained development. This essay illustrates the adaptability of MIT/MTT and SBT combined logging in casing damage detection and cementing quality evaluation in theory and practice respectively which further provides technical support for the oilfield management.
