摘要
阵列感应成像测井在大量的低电阻率油层测井综合解释中能够有效地确定储集层的含油饱和度 ,定量描述钻井剖面的侵入特性。简要地说明了国内最新研制的MIT型阵列感应成像测井仪的技术构成。介绍了该成像仪器的数字合成聚焦技术、井眼环境校正技术和测井试验等。通过在我国北部几个油田的多口井中与同类仪器对比试验分析 ,证明该仪器在薄层分析、确定地层电阻率及侵入特性等方面具有良好的应用前景。
In large amounts of log interpretations of oil zones with lower resistivity, array induction imaging logging is able to effectively determine the oil-bearing saturation in the zones and quantitatively describe the invasion features of the drilling profiles. Outlined are technical content of MIT array induction imaging tool newly developed in China. Introduced are the tool's synthetic digital signal processing technology, borehole environment correction and log experiments, etc. Comparative tests in some well of several oilfields in north China with the same type of tools show this new tool has better application prospects in thin layer analysis and determination of formation resistivity as well as invasion features.
