锦州27区多井约束地震反演及储层预测
|
摘要
锦州27区属于复杂断块区,地质建模比较困难,依赖于初始模型的常规反演方法难以获得精确的反演结果。利用约束稀疏脉冲反演技术提取井旁地震道的子波,形成了合成记录,对层位进行标定以及波阻抗反演,得到了绝对波阻抗剖面;并把绝对波阻抗剖面转换成砂泥岩剖面,其反演结果与井的钻探结果基本吻合;沿目的层顶面(T3u1)向下提取不同时间的平均波阻抗值和最大波阻抗值,并由此圈定出砂体发育带,进行储层预测。结果表明:在复杂断块地区采用约束稀疏脉冲反演技术,较之其它储层预测技术可以相对准确地预测储层岩性及展布规律,对油田的进一步勘探开发具有一定指导意义。
The 27th region,Jinzhou,belongs to complex fault-block area,it is difficult to build geological model.The use of the normal inversion method which is based on the initial model is difficult to get exact inversion result.The constrained sparse pulse inversion technology is used to extract the wavelet of near-well seismic traces,and synthetic record is generated,the bearing horizon calibrated,wave impedance inversion carried out,and the absolute wave impedance profiles obtained,then they are converted into sand-mudstone profiles.The inversion results are consistent with the drilling results.Thus the average and maximum wave impedance values of different times are extracted along the top of the target layer(T3u1) and the sand developed belts are located to predict the reservoir.The results shows that the use of constrained sparse pulse inversion in the complex fault-block area can be used to predict the lithological reservoir and distribution law with relatively high accuracy,which has some guidance significance for the further exploration and development of oilfield.
