本文以大庆长垣南气田敖7区块为重点研究区。在长期的勘探开发过程中,随着测井仪器的不断更新换代,测井资料采集系统应用多样化,研究区黑帝庙油层探评井测有老横向、JD-581、DLS及CSU等多套测井系列[1]。由于研究区不同测井时期完井泥浆电阻率变化范围较大,对自然电位、深侧向电阻率等测井曲线影响较大,因此开展了泥浆电阻率对测井曲线影响分析并优选反映储层流体性质的测井曲线。在试油、岩心分析及测井等基础资料调研及储层“四性”关系研究基础上,将各测井系列分类建立气水层识别图版,为研究区今后勘探、评价及开发中测井气水层识别提供了较好的方法。
In this paper, Daqing Changyuan gas field Ao 7 block as the key research area. In the course of long-term exploration and development, along with the constant replacement of logging tools and the diversified application of logging data acquisition system, the old wellings of the Heidimu reservoir in the study area have been measured with many JD-581, DLS and CSU Set of logging series [1]. Because of the wide range of well completion mud resistivity in different logging periods in the study area and great influence on the logging curves such as natural potential and deep lateral resistivity, the influence of mud resistivity on well logging curve is analyzed and the results of well logging Logging curves of fluid properties. Based on the investigation of basic data such as oil testing, core analysis and logging, and reservoir “four nature ” relationship, the logging series are classified into gas and water identification plates for future exploration, evaluation and development in the study area Well logging gas and water layer identification provides a better method.
