Source of Funding: Beijing Logging Technology Development Company, China Petroleum Logging CO. LTD.Abstract: Aiming at the problem of quantitative evaluation of cementing quality of second interfaces, a double-pulse method was proposed based on traditional pulse-echo logging technology. For the same measuring point, two echoes are measured with a wide band transducer and a narrow band transducer. Broadband transducer echo is used to invert casing inner diameter, thickness and acoustic impedance after casing. Using these parameters, SIE wave can be adaptively extracted from narrowband transducer echo to avoid the interference of casing resonance wave, so as to realize the quantitative evaluation of second-interface cementing quality.2018.10-2019.10, main participantProject name: Anti-interference high integrated parallel test of mobile audio. Project funds:￥731,300. Source of Funding: Huawei.Abstract: One of the procedures of mobile phone quality inspection is to test the speaker, handset and main and secondary microphones. The current practice is to place the mobile phone in the soundproof box and measure one phone at a time. As the production of mobile phones increases, the current detection method cannot meet the production demand. This project adopts an array test system, which uses multiple microphones, artificial ears and artificial mouths to solve each principal component from the coherent sound field, realizing the simultaneous detection of three mobile phones in a soundproof box and improving the detection efficiency by three times.2015.06-2015.11, project leaderProject name: Ultrasonic leaky-lamb wave propagation theory and field fast interpretation method researches for cementing quality evaluation of light cement. Project funds:￥906,000. Source of Funding: Logging Technology Institute, Great Wall Drilling Corporation.Abstract: For light cement, especially for foamed and cenosphere cement, the ultrasonic leaky-lamb wave technology and pulse-echo technology are studied numerically and experimentally. A fast, robust and high-precision interpretation method of cement bond evaluation is proposed, and the new method is verified by experimental data. 2013.11-2015.06, project leaderProject name: Forward numerical simulation and inverse method study of asymmetric acoustic field.Project funds:￥340,000.
