摘要(Abstract)：

为研究塔河油田九区三叠纪下油组厚砂体内部夹层识别与分布,综合岩心、测井及动态资料,结合水平井电阻率曲线反演识别夹层,利用直井和水平井联合控制的方法进行夹层识别及夹层井间分析。根据夹层参数定量统计分析及沉积相分布,分析夹层的空间分布规律。结果表明:研究区夹层主要为泥质夹层和钙质夹层两类,通过单井定性识别及水平井电阻率曲线反演综合确定夹层的平面分布范围,平面上夹层大小不一、分布比较零散、连续性差,呈薄厚不等的透镜状、长条状。泥质夹层受沉积微相控制,顺物源北东方向展布,主要为辫状河三角洲平原和辫状河三角洲前缘分流河道边部溢岸沉积;钙质夹层相对较发育,主要分布于辫状河三角洲前缘沉积环境中。夹层分析结果为后期剩余油分布研究提供参考。
