摘　　要：在进行井架承载能力评定时,现有的检测方法存在诸多不足。结合现有计算机图片处理功能,设计了一套基于数字散斑相关技术的井架应变测量方法。与现有的电测法得到的井架应变测量结果对比,基于数字散斑相关技术的井架应变测量方法的测量结果精确、可靠。此测量方法减轻了劳动强度,提高了工作效率,解决了现有井架承载能力评定工作中应变测量方法存在的不足。基于数字散斑相关技术的井架应变测量方法为井架承载能力评定提供一种新的应变测量方法,对更加科学、合理、全面地评定钻修机井架的承载能力具有实用价值。Against the existing detection of measuring method for an existing derrick bearing ca- pacity assessment. Combined powerful computer graphics processing capabilities, design a measur- ing method of derrick strain based on digital speckle correlation technique. Through comparing derrick strain measuring on site with Electrical Measuring method, can be conclude that the meas- uring results from measuring method of derrick strain based on digital speckle correlation tech- nique are accurate and reliable. At the same time, this measuring method reducing the labor inten- sity largely, improving the work efficiency. Solved the existing problems of derrick measuring method in the presence. Providing a new strain measuring method for derrick bearing capacity e- valuation, having important practical value for derrick bearing capacity assessment on more scien- tific, rational, comprehensive.
