针对红台油气田侏罗系三间房组砂体发育变化大,储层认识不清等难点,将三间房组组划分为5个砂层组和17个小层。利用常规测井曲线进行小层划分与对比,总结出标准层附近的等厚(等高程)、标志层对比、沉积相相变对比、沉积旋回四种对比方法,体现了等时地层单元的含义,避免了砂体窜层和漏划分的现象,使得地层层划分对比工作趋于合理。 In view of the difficulty of sandstone development in the Jurassic Sanjianfang Formation in Hongtai oil and gas field and unclear understanding of reservoirs, the Sanjianfang Formation is divided into 5 sand layers and 17 small layers. Using the conventional logging curves to divide and contrast the small layers, the paper summarizes four types of contrast methods such as isopachies, markings contrasts, sedimentary facies contrasts and sedimentary cycles in the vicinity of the standard layers, which reflect the meaning of isochron stratigraphic unit , To avoid the sand body channeling and leakage of the division of the phenomenon, making stratification stratigraphic comparison work tends to be reasonable.
