随着大斜度井、水平井的普及,随钻测井(LWD)在现场的应用也越来越广泛。它所提供的实时数据在地层评价和地质导向中发挥了很重要的作用。但是由于受围岩、泥浆侵入、地层与井眼的夹角及仪器探测深度等因素的影响。导致有些测井曲线出现异常。本文就测井曲线出现的异常情况作了相关的浅析。希望对现场施工人员有所帮助。 With the popularization of high deviated wells and horizontal wells, the application of LWD in the field is more and more widely. The real-time data it provides play an important role in formation evaluation and geosteering. However, due to the surrounding rock, mud invasion, the angle between the formation and the borehole and the depth of the instrument to detect and other factors. Resulting in some well logs abnormalities. This paper makes an analysis on the abnormal situation of logging curve. Hope to help the construction site workers.
