提出一种基于相对幅值法的接箍深度识别方法.该方法利用计算机处理技术对接箍曲线应用相对幅度鉴别方法,自动跟踪识别接箍深度,尤其是能够自动跟踪识别受套管磁化干扰信号影响的接箍深度.该方法识别的接箍深度比使用简单的门限值,识别范围及最大值方法计算的接箍深度更准确,精度也更高,能够有效确定射孔作业深度,防止误射孔发生,为油田薄油层的开采提供技术保证,应用效果良好.
A method based on relative amplitude method of collar depth identification was put forward in this paper. By using the relative amplitude method to automatic track and identify collar depth, especially to accurately identify the collar depth which were effected magnetized collar, this new technology was better than simple threshold, identification range and the maximum method, which ensured the perforation precision, safety and reliability, avoided error perforations, provided a guarantee for thin beds production. This technology has been better used.
