ABSTRACT

In order to guarantee the smooth progress of the deep gas well fracturing and subsequent development must be qualitative and quantitative evaluation of the deep gas well casing quality, this paper puts forward the small diameter dobby multi-arm caliper and electromagnetic defect detection combined logging technology scheme for deep gas well casing quality evaluation, by using this scheme for A1 Well, A2 Well and A3 well downhole testing and anticorrosive 13Cr casing pipe surface test. The test results show that there are the small diameter dobby multi-arm caliper and electromagnetic defect detection combined logging for deep gas well casing quality detection technology that can be judged, downhole casing degree of risk, for gas recovery branch fracturing, well completion, workover, and provide a reliable basis for the establishment of perforation scheme.
