| 1 | 随钻声波测井新技术显示文摘在诸多钻井决策中,优选泥浆比重是最具挑战性而且也是最重要的决策之一。如今,新型随钻声波测井仪器的应用能够更好地帮助钻井工程师进行这些钻井决策。 | Jeff Alford Roger B.Goobie Colin M.Sayers Ed Tollefsen Jay Cooke Andy Hawthorn John C.Rasmus Ron Thomas | 2007 | 国外测井技术2007，22，1： | 8 |
| 2 | 随钻声波测井新技术显示文摘工程师根据声波测井仪记录的声波资料以更高的安全系数提高钻井效率,优化完井方式。LWD声波测井仪是在上世纪90年代中期问世的,能够记录纵波资料,但不能记录所有地层的横波资料。新型LWD声波测井仪能记录以前无法得到的横渡资料,工程师正在利用横渡资料优化钻井作业,确定最佳钻进方向,识别具有更好完井特征的岩层。 | Jeff Alford Matt Blyth Ed Tollefsen John Crowe Julio Loreto Saeed Mohammed Vivian Pistre Adrian Rodriguez-Herrera | 2013 | 国外测井技术2013，，2： | 2 |
