摘要
湿接头水平井测井在施工过程中必须靠钻具或油管提供动力来推进仪器进行测井,仪器在测井过程中所处的位置及测量环境不同于普通直井。随着水平井的开发日益增加,水平井测井中密度与井径的数据采集的缺陷也日益显露,从而影响对地层的准确评价。针对这一问题,分析密度与井径在水平井测井中的特殊环境以及其测井原理与方法,着眼于水平井测井工艺的配套分析,同时涉及密度与井径的数据采集及传输。根据分析逐步提出影响密度与井径测井的问题所在,最后提出解决思路与方法。
During wet connection logging in the horizontal well, the drillpipe-conveyed logging system enables the operator to locate logging tools in high-angle well though the position of logging tools in the horizontal well is different from that in the normal vertical well. As more and more horizontal wells have been developed,some problems from data acquisition of the density and the caliper occured in the horizontal well logging, which affects accuracy of formation evaluation. In view of this situation, analyzed are the methods and principle of density and caliper logging in hostile environment. Emphasized are compatibility of toolpusher logging technology, data acquisition and transmission of the density and caliper logging. According to the analysis, causes of the troubles are pointed out and the methods of improvements are also given herein.
