电声成像模拟测量装置方案设计及优选

 针对测井仪器在使用和推广中,缺乏系统的、理论性应用基础方面的室内研究手段而难形成商业化规模,制约了其发展的问题,根据微电阻率成像和超声成像的工作原理及实际运动测量的模式,并结合实验室用的特点,设计了一套井周电声成像探测器模拟测量装置,该装置实现了x、y、z及d(圆周)4个方向的运动,在x、d方向设计了多种方案.利用模糊评判的原理,对d和x方向的多种方案进行了综合评价,建立了隶属函数及权重,通过专家打分的形式建立因素集及模糊综合评判集,选取以x为双直线电机传动,d为锥齿轮传动方式为最优方案,该测量装置能为成像技术的深入研究提供手段.

Design and Optimization for Analog Measuring Equipment of Electroacoustic Imaging

For logging instrument in use and promotion, the lack of system and the application of theoretical basis of indoor research means that it's difficult to form the commercial scale and restricts its development seriously. According to the operating principle of micro resistivity imaging, ultrasonic imaging, the model of the actual motion measurement and combining with the characteristics of the laboratory, we devised an analog measuring equipment for electroacoustic imaging detector, which had realized the movement of x, y, z and d four direction, devised various schemes for x,d. We used the principle of fuzzy evaluation to establish membership functions and weight for various schemes of x, d directions. Using the principle of fuzzy evaluation, we evaluated kinds of schemes of the d and x direction comprehensively, and established the membership function and weight. We established factors set and fuzzy comprehensive evaluation set through the expert scoring form and selected the optimal case, x as double linear motor transmission; d as bevel gear drive. The measurement device could provide further research of methods for imaging technology.
