摘要: 渤海湾盆地新滩油田垦东32—33块已进入隐蔽油气藏勘探阶段,薄层河流相砂岩的地震预测是本区滚动勘探开发的关键。为此,应用尚未广泛推广的Conseis系统对研究区进行小波分频域高分辨率处理、测井曲线重构和构造—测井约束非线性反演储层预测,对薄砂层进行有效识别,预测砂体平面分布,结合油水分布特征,指导油气滚动勘探开发。经钻井证实,具有很高的成功率。Abstract: The block KD32-33 in Xintan Oil Field of the Bohai Bay Basin has already come into the stage of subtle oil and gas reservoir exploraion.The seismic prediction of thin-bedded fluvial sandbodies is the key for rolling exploration and exploitation in this area.Applying the Conseis complex oil and gas reservoir forecast system which has not been generalized,the reconstruction of well-log and the reservoir prediction of texture-logging constraint nonlinear inversion are made.Thin-bedded sandbodies are effectively recognized.The planar distribution of sandbodies is predicted,instructing the rolling exploration and exploitation of oil and gas.The attainment rate is confirmed high by drilling wells.
