南堡2号潜山碳酸盐岩储层叠前和叠后裂缝综合预测
|
摘要
针对南堡2号潜山顶部奥陶系非均质碳酸盐岩储层,基于宽方位角采集的地震资料,结合已有钻探成果,开展了碳酸盐岩缝洞型储层的地震综合预测研究。在对地震资料进行相对保幅处理的基础上,通过构造精细解释落实潜山顶面层位和断裂格局;应用P波方位各向异性分析技术进行叠前裂缝预测,利用曲率属性技术进行叠后裂缝预测,再辅之以叠后衰减梯度属性检测溶蚀孔洞分布。通过叠前、叠后预测结果的对比分析,以及FMI成像测井解释结果和钻井实际生产效果的验证,证明了研究思路的正确性和所用预测方法的有效性。综合预测研究成果为圈定南堡2号潜山奥陶系储层裂缝发育的有利目标区提供了依据。
Based on wide-azimuth seismic data and drilling data,the seismic comprehensive prediction of Ordovician heterogeneous carbonate fracture-carst reservoir was conducted in the top of Nanpu2 buried-hill.On the basis of seismic data amplitude-preservation processing,the surface layer and fracture pattern of Nanpu2 buried-hill is identified by fine structure interpretation.Meanwhile,the P-wave azimuth anisotropy analysis technique is used to carry out pre-stack fracture prediction and curvature attribute is adopted to carry out post-stack fracture prediction.Moreover,post-stack attenuation gradient is utilized to detect the distribution of caves.By comparing the pre-stack and post-stack prediction results,combined with FMI imaging logging interpretation result and drilling data,we proved the correctness of our research clue and the effectiveness of the prediction methods.The comprehensive prediction results provide a basis for identifying the potential target area of Ordovician carbonate reservoir in the Nanpu2 buried-hill.
