贝尔凹陷扇三角洲河道砂体刻画及油气勘探开发意义
|
摘要
为定量刻画断陷盆地内扇三角洲河道砂体的时空分布特征及其对于油气勘探开发的影响,利用井-震合成记录标定和储层反演对海拉尔盆地贝尔凹陷苏德尔特构造带兴安岭组Ⅰ、Ⅱ、Ⅲ油组河道砂体进行识别。通过均方根属性切片反演三个油组河道砂体范围,甜点属性刻画河道形态,结合重点井位单井相得出兴安岭组Ⅰ、Ⅱ、Ⅲ油组的沉积相图。对河道砂体储层定量计算,得出Ⅰ、Ⅱ、Ⅲ油组河道参数。结果表明:兴安岭组Ⅰ油组主要发育水下分流河道微相,河道宽度范围800～1 500 m,厚度范围7～9 m;Ⅱ油组以水下分流河道、河道侧缘溢岸砂和河道间砂沉积为主,河道宽度范围450～650 m,厚度范围4～6 m;Ⅲ油组主要发育席状砂,河道间砂和席间泥,河道宽度范围130～170 m,厚度范围在2. 5～4 m。结合沉积微相、河道参数及生产动态资料,得出研究区河道砂体既控制油气分布与储产比,也控制油水流通和注采受效。
In order to quantitatively characterize the spatial and temporal distribution characteristic of sandbodies and its significance of oil and gas exploration and development in fault basin,synthetic seismogram and reservoir inversion were integrated to identify the channels sand bodies from Ⅰ,Ⅱ,Ⅲ oil groups of Xing anling formation of Sudeert structural belt,Beier sag,Hailar basin. The RMS attribute was used to describe the distribution of sand body. The sweetness had been used for channel description. Combined with single well facies,the sedimentary microfacies of Ⅰ,Ⅱ,Ⅲ oil groups had been profiled. The results show that the microfacies of Ⅰ oil group is mainly developed underwater distributary channel,the cover thickness of channels from Ⅰ oil groups from 800 to 1 500 m,the thickness range from 7 to 9 m; The microfacies of Ⅱ oil group is mainly developed underwater distributary channel,overbank sand and interchannel sand,the cover thickness of channels from Ⅱ oil groups from 450 to 650 m,the thickness range from 4 to 6 m; The microfacies of Ⅲ oil group is mainly developed sheet sand,interchannel sand and sheet mudstone,the cover thickness of channels from Ⅲ oil groups from 130 to 170 m,the thickness range from 2. 5 to 4 m; Combined with sedimentary microfacies,channel parameters and dynamic production data,it is concluded that the channel sand bodies not only control the oil and gas distribution and production,but they also control the oil and water circulation and injection-production results.
