摘　　要：为发现并解决油田生产过程中井筒出现的各类问题,采取有效措施保证井筒完整性,确保油水井正常生产,通过小直径多臂井径、脉冲中子氧活化、电磁探伤、井温噪声等多种测井方法的组合应用,准确给出井筒完整性评价结果。实践结果表明,组合测井方法综合应用是解决井筒问题的有效手段,为采油厂压裂、完井方式、修井和射孔方案的制定提供重要依据。In order to find and solve different kinds of problems in wellbore and take effective measures to ensure wellbore integrity and normal production of oil and water wells,the combination of different logging methods,such as small-diameter multi-arm diameter,pulse neutron oxygen activation,electromagnetic flaw detection,temperature noise and so on is applied and the evaluation result of wellbore integrity is accurately given.It is effective to solve wellbore problems and provides important scientific basis for the establishment of fracturing,well completion,workover and perforation schemes in oil production plants.
