摘　　要：针对深层气井的特点提出了小直径多臂井径和电磁探伤相结合的深层气井套管质量评价方法,并采用该方法对AS9-P5井、AS27-P1井和AS3-P2井的井下套管进行了测试。结果表明,小直径多臂井径和电磁探伤深层气井套管质量检测技术可以有效判断深层气井井下套管风险程度,为压裂、完井方式、修井和射孔方案的制定提供可靠依据。According to the characteristics of the deep gas well,the method for casing quality evaluation is put forward with the combination logging of small diameter multi-arm caliper and electromagnetic detection tool.The testing results in AS9-P5 well,AS27-P1 well and AS3-P2 well show that the technology can effectively evaluate the downhole casing risk,which can provide reliable basis for establishing schemes of fracturing,well completion,well workover and perforation.
