钻屑随钻处理技术研究

Study on Treatment Technology of Drill Cuttings While Drilling

介绍了国内外钻屑处理技术现状,提出一种新型钻屑随钻处理实施方案,研制出了关键技术设备。现场试验结果表明:具有钻屑随钻处理功能的新型钻井液固控系统能够满足我国实际钻井工况要求,推广应用前景广阔。

Based on analyzing the domestic and international situation of treatment technology of drill cuttings, the kind of new technical scheme of treatment technology of drill cuttings while drilling was put forward,that the drilling technology of minor cycle without mud pit can be real- ized and the drill cuttings according with the conditions of transport through dewatering and dr- ying can be carried away from drilling well site before falling onto ground. The key equipment was developed,which has been tried in lab and on site through 3 wells. The results showed that the new mud solid control system with treatment technology of drill cuttings while drilling had a good adaptability to meet the actual drilling condition in China. This technology has broad application prospects
