基于岩心、钻井和测井等新资料,结合大量岩矿测试分析,对河套盆地临河坳陷古近系渐新统临河组深层—超深层碎屑岩储层特征、成岩作用类型、异常高孔储层成因及发育控制因素开展系统分析。研究表明:(1)临河组深层—超深层碎屑岩异常高孔储层储集空间以原生孔为主,抗压实能力强的物质组构基础、弱压实成岩动力场和流体弱压实-弱胶结成岩环境等3大有利成岩要素耦合利于原生孔大量保存;(2)临河组碎屑岩先存物质组构优越,石英、长石和刚性岩屑总含量平均值可达90%,抗压实能力强;(3)临河坳陷地温梯度低,仅为(2.0~2.6)℃/100 m,与早期长期浅埋—晚期快速深埋的埋藏方式共同形成弱压实成岩动力场环境;(4)咸化湖盆沉积地层的成岩环境中,成岩流体产生的压实作用弱,同时古盐度具有分异性,低盐度区胶结作用弱,利于原生孔保存;(5)沉积水动力条件、咸化湖盆古水体盐度分异和砂体厚度等3大因素共同控制临河组优质储层分布。

目的对Dilon 6800多晶体伽马相机进行系统均匀性测试,分析数据并探讨质控方案,提高图像质量,确保设备正常运行。方法根据用户手册、美国国家电气制造商协会标准、美国医学物理学家学会报告、美国核医学会指南和生产厂商建议,测试并收集2016—2021年的每月系统均匀性数据,若其有效视野积分均匀性数值≥9.50%则加以校正。分析数据并根据每月平均湿度将其分为高低湿度组,比较2组有效视野均匀性均值的差异。结果 2016—2021年每月的有效视野积分均匀性的校正后最终值保持在10.00%以下,在可接受范围内。校正后均匀性显著优于校正前。高湿度组的有效视野均匀性原始值显著高于低湿度组。结论通过总结Dilon 6800多晶体伽马相机的质控方案,并采用系统均匀性测试,评估得出观察有效视野积分均匀性比微分均匀性更有效。及时校正可恢复并保持设备的均匀性指标,且湿度与机器均匀性性能有关,因此应关注高湿度对设备的影响。
