摘要:
高邮凹陷北斜坡成藏条件优越,伴随多年勘探挖潜,勘探领域逐渐向火山侵入区推进,受火山侵入岩影响圈闭落实难度加大。在分析火山侵入岩测、录井特征、地震相类型划分基础上,利用正演模拟侵入岩与正常围岩地震响应关系,进行北斜坡弱反射目的层的层位解释; 从侵入岩剖面特征出发,通过最大曲率、滤波相干处理等技术明确断层平面组合方式,有效提高圈闭识别精度; 利用敏感属性刻画侵入岩发育边界; 通过井-震层位标定定量预测侵入岩区的目标有效储层厚等技术手段,大大提升圈闭评价可靠性,较好地指导了北斜坡侵入岩区勘探生产,效果显著。
Abstract:
The northern slope of Gaoyou Sag has favorable reservoir formation conditions. With years of exploration and potential exploration, the exploration field has gradually advanced to the developmental area of volcanic intrusive rocks, and the trap definition become to be difficult due to the effect of volcanic intrusive rocks. Based on the logging characteristics of volcanic intrusive rocks and the classification of seismic facies types, the forward modeling was used to simulate the seismic response relationship between intrusive rocks and normal surrounding rocks, which can be utilized to guide the horizon interpretation of weak-reflection target layers in the northern slope. According to the section characteristics of intrusive rocks, through the method of maximum curvature and filtering coherent processing, the combination of fault planes was clarified, and the accuracy of trap identification was effectively improved. Sensitive attributes was used to define development boundaries of the intrusive rocks. Through well and seismic data, effective reservoir thickness in intrusive rock zone could be quantitatively predicted, greatly improving the reliability of trap evaluation and better guiding the exploration and production of the intrusion rock area of North Slope, which gains significant effect.
