渤东凹陷蓬二号构造地震资料测井约束反演
|
摘要
根据岩心、岩相资料和速度统计,对目的层馆陶组砂泥岩速度差异及其相应的地震反射界面进行了分析。通过精细的速度研究与地震地质模型分析,以及多次子波提取与反复细致标定,将常规地质界面型剖面反演成地层岩性型剖面,得到了4个低波阻抗段。这4个低波阻抗段分别对应的储层段为:(1)3150～3170m井段,为蓬xl2井测井解释的含水、油层段;(2)3215～3250m井段,为蓬xl2井测井解释的主要含油层段;(3)3300～3400m井段,为蓬xl2井测井解释的含油水层段;(4)3465～3495m井段,为蓬莱xl2井测井解释的含油水层段。
Velocity contrast of sandstone and mudstone and the corresponding seismic reflecting horizons in the targeted Guantao Formation are analyzed based on core and lithofacies data and velocity statistics. Through detailed velocity study and seismogeological model analysis, as well as multiple wavelet extractions and repeated and detailed calibrations, the conventional geologic interface profile is inverted into a stratigraphic-lithologic profile. Four low wave impedance intervals are identified which correspond to the following 4 reservoir intervals: (1) 3150-3170m, log interpreted water-and oil-bearing interval in Peng xl2 well; (2) 3215-3250m, log interpreted main oil-bearing interval in Peng xl2 well; (3) 3300-3400m, log interpreted water-oil-bearing interval in Peng xl2 well; (4) 3465-3495m, log interpreted water-oil-bearing interval in Peng xl2 well.
