利用地震属性资料解释河道
|
摘要
地下某一层段的地震属性特征通常揭示了一些地质或沉积特征,如礁体、河道、三角洲、地台等。文中采用分层段切片解释方法,对塔河油田外围兰尕三维资料进行切片分析,在三叠系上油组地层中的振幅属性平面图上分布有南北方向的河道,地震解释剖面及钻井资料也得到证实。研究中发现,分析时窗的大小决定了振幅属性在河道处能量的强弱,根据河道的分布可以追踪河道砂岩体及其分布范围,为研究有利储层提供了可靠依据。
Some attributes normally reveal a number of geological and sedimentary features in formation,such as the reeg,river,delta and platform,etc.By stratified slice interpretation method in the paper,3D data of the outside of the Tahe Oilfield are analyzed and it is found that the area distributes a north-south channel on the amplitude attribute distribution map in the of T46s Group,Upper Triassic strata,which has been confirmed in drilling and seismic interpretation profiles.It is discovered in the research that the window size determines the energy strength of amplitude attribute of the channel.According to the distribution of the channel,the channel sand and its distribution can be tracked,which provides a reliable basis for studying favorable reservoir.
