管壁超声彩色成像测试技术在桥、马油田的应用

Application of the Three-Dimensional Borehole Television Technology in Qiaokou and Machang Oilfields

针对目前油水井井下套等损坏程度判断不清的现状，引进了管壁超声彩色成像测试技术，它是一项反映井下套管状况的新技术。该技术利用声波在井内介质中的传播和反射特性，对套管内壁进行快速扫描，在屏幕上可直观地显示出套管的各种情况。通过该技术的应用，救活了原定不能再生产的2口井——马11-129和桥29-37井，并取得了较好的经济效益。

For the casing pipe was broken down,the three-dimensional borehole television technology was introduced,it is a new technology that view the condition of downhole. According to the feature of propagation and reflection of sonic in the borehole medium,this technology scan quickly around the casing inner wall and the condition of casing can be applied to 2 wells-Ma 11-129 and Qiao 29-37 which had been abandoned,we have made great economic profits.
