The invention relates to an CBL and SBT logging integrated simulation experimental device and a method thereof, which comprises a main probe cylinder, a probe, a wall probe box moving block, a pushingarm and an inner probe box, wherein the main probe tube is arranged outside the probe of a cylindrical structure, the wall probe box moving block and the pushing arm are arranged in the probe; the pushing arm is connected with the wall probe box moving block; the pushing arm and the wall probe box move block form a sliding mechanism, moving up and down inside the main probe cylinder; the upper part and the lower part of the probe are respectively provided with the inner probe box, and the inner probe box is filled with a coupling agent used for protecting the probe. The device of the invention can perform CBL logging and SBT logging at the same time, not only can carry out overall evaluation on the cementing quality, but also can carry out partial sector evaluation, qualitative and quantitative evaluation of the cementing quality in a certain direction.
Description
technical field [0001] The invention relates to a well logging instrument for evaluating cementing quality through sound waves, in particular to a CBL and SBT well logging integrated simulation experiment device and method. Background technique [0002] The sonic logging tool is an instrument used to detect the cement bond quality of cased wells. With the increasing requirements for the wellbore integrity of oil and gas wells, it is more and more important to evaluate the cement bond quality after cementing. At present, the logging methods that are widely used in oilfield enterprises are mainly CBL (acoustic amplitude logging) and SBT (sector logging). [0003] At present, the logging methods that are widely used in oilfield companies are mainly CBL acoustic amplitude logging and SBT sector logging. The CBL sound amplitude logging results reflect the overall situation of the casing and cement sheath cementation quality between the transmitting probe and the receiving probe;...
