【摘要】 介绍了陕北安塞郝家坪油区的地质特征,含油地层岩性特征。针对在该区开展生产井测井工作中地球物理测井方法的选取原则、选取情况,综合确定了适用于该区的经济有效的地球物理测井方法。阐述了该区标志层的岩性特征和测井曲线组合特征、含油层的岩性特征和测井曲线组合特征,并对测井仪器的选取情况做了相应说明。介绍了野外资料采集的步骤和注意事项、测井成果解释的具体方法、所运用的经验公式以及参数选取情况,重点介绍了孔隙度、含油饱和度、渗透率k以及残余烃、可动烃、水各占孔隙的计算方法,总结了本区含油饱和度划分油水层的原则。以该区的塞新1、塞天马16两口井为例,浅析了该解释方法的应用,取得了很好的效果。更多还原

【Abstract】 This paper introduces the geological and lithological characters in Northern Shaaxi Ansai and Haojiaping Oil section. The economical and efficient log methods are determined according to the selecting strategies of geophysical log in the prduction wells of this area.The authors descrbe the lithological and log graph characters from both signing layer and Oilbearing information.The instrament, date acquisition and interpretation are introduced as well, especially the porosity, permeability and oilwater layer division criteria. At last we analgze the application of the methods to well saixin No.1 and well saiTianMa No.16 and achieve good results.更多还原
