据外刊报导,最近,在费顿山新墨西哥致密的花岗岩中打了两口井,井深都在6500英尺以上。并根据高能流体在流动过程中会产生涡流噪声这一原理,采用噪声测井进行了测量。结果表明,噪声测井仪如果与井温及其它测井仪组合,则可能成为比以往所有仪器都更为有用的诊断手段。第一次试验是把它作为判断管外流体的常规手段,对水泥胶结测井曲线显示的结果作了进一步的验证,即由于地温很高(200℃),注入冷水后,热应力震动加剧,致使底部套管外面的水泥环有损坏现象。人们发现,在注入井中,固井已三年的水泥环有1300英尺长的一段布满了流体孔道;在生产井中,圆井仅一年的水泥环也开始变坏。采用噪声和井温组合测井的方法来划分管外环形空间的注入水和实际上已流入花岗岩地层的注入水,发现在水力压裂区域2500英尺井段的花岗岩地层中有注入水流动,生产层噪声测井 According to a foreign press report, two wells were drilled recently in dense granite in Mount Fitton, New Mexico, well above 6500 feet. According to the principle that high-energy fluid will generate eddy noise in the flowing process, noise logging is used to measure. The results show that noise logging tools, when combined with well temperatures and other logging tools, may be a more useful diagnostic tool than ever before. The first experiment is to use it as a conventional means to judge the fluid outside the tube to further verify the results of the cementing logging curve. That is, due to the high ground temperature (200 ℃), after the injection of cold water, the thermal stress and vibration intensify, Resulting in the bottom of the casing outside the cement ring is damaged. It has been found that cementing wells that have been cementing for three years in cement injection wells have been filled with fluid channels for a period of about 1,300 ft. In production wells, cement rings, which were only a year old in the well, began to deteriorate. A combination of noise and well temperature logging was used to divide injected water into the annular space outside the tube and injected water that had actually flowed into the granite formation and found to have injected water flowing in the granite formation in the 2500 ft well section of the hydraulic fracturing zone Layer noise logging
