摘要
最大限度地降低噪声强度,对于提高SDI-MWD无线随钻测量仪信号质量至关重要。现场应用表明,井深、 钻井液性能、钻井液马达等均可能影响测量信号的质量。分析了产生噪声信号的原因,并给出了相应的降低噪声信号强 度的技术措施。以两口井为例,介绍了SDI-MWD无线随钻测量仪器在应用过程中易出现的问题及采取的技术措施。
Reducing noise as much as possible is significant to improve signal quality of SDI-MWD. Filed applications show that the measured signal quality is maybe affected by well depth, drilling fluid properties and mud motors, etc. This paper analyzes reasons for noise signal and presents the technical methods to reduce it. Taking two wells for example, this paper introduces the most common problems and the countermeasures while using it.
