【摘要】 孤北洼陷南部斜坡带的主要含油层是沙三段亚段第四、第五砂层组,其储层纵横向变化快,合油性复杂多变,用常规方法难以识别。通过深入分析石油地质条件,提取地震属性和地层切片技术预测有效储层发育带,测井约束反演技术描述储集层,应用吸收滤波技术判识砂体的含油性,最后提出勘探方向。更多还原

【Abstract】 The main oil-bearing formations on the southern slope belt of Gubei subsag belong to the IV and V sand group of Es3, which is difficult to identify with normal methods for rapid vertical-lateral variation and complicated oil-bearing probability. According to thorough analysis on the petroleum geological conditions, seismic attributions extraction and formation slice could be used to predict the growth belt of effective reservoir, the logging constraining inversion can be used for reservoir description, filtering absorbing technique can be used to identify the oil-bearing probability of sandbody. Exploration direction is located at last.更多还原
