测井检波器是进行地震测井不可缺少的仪器之一。对于检波器的技术要求是能够耐高温度,耐高压力,高灵敏度和高阻尼相结合,防水绝缘性能好等。我们搜集调查研究了井下的各项资料以及检波器的有关资料,参考了兄弟队的先进经验,进行了试制。并在3133M井中进行了试验,试验过程中和试验前后测井检波器各项技术性能稳定,完全符合要求,与国产DJ_3测井检波器进行了比较,并顺利地完成了该井的地震生产测井工作。有关技术性能如下: 一、检波器的结构:(图1) 1.耐高压力。由于3000M以下的井底压力大于384个大气压,我们调查井下各种
Well logging geophones are one of the indispensable instruments for seismic logging. The technical requirements for the detector is able to withstand high temperatures, high pressure, high sensitivity and high damping combination, waterproof insulation and so on. We collected all the information of underground investigation and geophone investigation, reference advanced experience of brothers, trial. And tested in the 3133M well. Before and after the test, the technical performance of the logging geophones was stable and fully met the requirements. Compared with the domestic DJ_3 logging geophones, the well seismic production was successfully completed Well working. The technical performance as follows: First, the detector structure: (Figure 1) 1. High pressure. Since the bottom hole pressure below 3000M is greater than 384 atm, we investigated various types of downhole
