塔河油田卡拉沙依组地震沉积学研究与储层预测
|
摘要
针对塔河油田石炭系卡拉沙依组储层含灰质严重造成砂泥岩波阻抗值接近的特点,开展地震沉积学研究,用时频分析的方法在卡拉沙依组CK3和CK4砂组中划分3个最小等时研究单元及其对应的短期等时沉积界面;采用岩石—岩相物理分析确定了最小等时单元对应的地震响应特征,其中厚砂岩为强振幅反射;通过定量地震属性相分析提出用伪熵和扭度属性刻画薄层砂泥岩分布的方法;采用相控属性投影技术进行相控储层预测,并将有利沉积微相平面范围投影到过井的岩性反演剖面中,在三维空间中确定了有利储层展布形态,实现了实践意义上的"相控"理念,证实了地震沉积学在沉积相分析及岩性圈闭预测方面具良好的学科优势。
According to the characteristics of sand impedance close with shale's in Karratha reservoir containing carboniferous seriously,the article put forward facies-controlled reservoir prediction using seismic sedimentary.The article described key technology methods of the seismic sedimentary,such as the smallest isochronia-unit built by time-frequency analysis,rock and lithofacies physics phase analysis to determine the seismic response under the smallest isochronia-unit.Research results suggested that the thick sandstone with strong oscillation amplitude reflection.The plane quantitative analysis of pseudo-seismic entropy and twisting properties of the distinction between the effective distribution of sand and shale,may provide information for portraying the distribution of sand and shale accurately and for choosing favorable zones.Sand shape is described by attribute projection technology using inversion data.The research carried out the practical significance of the concept of facies-controlled reservoir prediction,demonstrated good discipline advantages of the seismic sedimentology in the sedimentary micro-facies analysis and forecasting lithologic traps.
