摘　　要：随着地质对象越来越复杂,资源品质越来越低,工程作业要求越来越高,“测量难、评价难”成为测井面临的突出问题。致密碎屑岩矿物组分复杂,孔隙度低,孔隙结构复杂,非均质性强,导致测井流体识别、孔隙结构与产能评价困难。此外由于自然产能低,需要测井为压裂改造提供岩石力学参数。通过对致密碎屑岩测井系列适应性分析,区域井(参数井)/预探井测井系列必测项目应包括双井径(方位)、自然伽马能谱、自然电位、双侧向-微球/双感应-八侧向电阻率、补偿声波、岩性密度、补偿中子、井斜方位、井温、元素扫描、微电阻率扫描成像、核磁共振(二维)和阵列声波测井项目。评价井测井系列在探井测井系列基础上,减去元素扫描、微电阻率扫描成像、核磁共振(二维)和阵列声波测井项目。水平井/大斜度井根据井况参照直井测井系列。As geological objects become more and more complex,resource quality is lower and lower,and engineering operation requirements are getting higher and higher,"difficulty in surveying and difficult in evaluation"has become a prominent problem facing logging.Tight clastic rocks have complex mineral components,low porosity,complex pore structure,and strong heterogeneity,which lead to difficulties in logging fluid identification,pore structure and productivity evaluation.In addition,due to the low natural productivity,logging is required to provide rock mechanics parameters for fracturing.Based on the analysis of the suitability of the tight clastic rock logging series,the required test items for the regional well(parametric well)/exploration well logging series should include dual diameter(azimuth),natural gamma energy spectrum,spontaneous potential,and dual lateral direction-Microsphere/dual induction-eight lateral resistivity,compensated acoustic wave,lithological density,compensated neutron,well deviation azimuth,well temperature,element scanning,micro-resistivity scanning imaging,nuclear magnetic resonance(two-dimensional)and array acoustic logging project.The evaluation well logging series is based on the exploratory well logging suits,minus element scanning,micro-resistivity scanning imaging,nuclear magnetic resonance(two-dimensional)and array acoustic logging projects.Horizontal wells/highly deviated wells refer to vertical well logging suits according to well conditions.
