【摘要】：英台地区黑帝庙油层在探评过程中发现存在储层发育零散,沉积相刻画难度大两个难点。本次研究以层序地层学、石油地质学理论为指导,以完钻井资料为线索,运用高精度储层预测技术,对英台地区黑帝庙油层储层分布进行预测。研究过程中,应用层序地层学原理,对重点层段进行高频层序划分和对比。利用地震沉积微相研究及岩心资料确定砂体特征,通过建立地质-地球物理模型,结合储集岩实验分析结果,精细刻画储层展布规律。通过本次研究工作,探索出一套适合本地区地震沉积微相研究技术——首先,开展英台地区典型的地质体(如分流水道、河口坝等),在地质-地球物理响应关系上的研究;然后,在正演模拟结果指导下,开展地震相(地震反射构型)、单井相、地震属性等研究;最后,在宏观古地貌约束下,综合研究地震沉积微相平面展布特征。对英台地区黑帝庙油层的层序划分与对比有了更好的认识,明确了英台地区黑帝庙油层的储层发育特征,这一成果对该区进一步的勘探开发具有一定的指导作用。
[Abstract]:In the process of exploration and evaluation of Heidimiao reservoir in Yingtai area, it is found that there are two difficulties in reservoir development and distribution, and it is difficult to depict sedimentary facies. Under the guidance of sequence stratigraphy and petroleum geology theory and with the clue of drilling data, the distribution of Heidimiao reservoir in Yingtai area is predicted by using high-precision reservoir prediction technology. In the course of the study, the high frequency sequence division and correlation of the key strata are carried out by applying the sequence stratigraphy principle. By using seismic sedimentary microfacies and core data to determine the characteristics of sand body, a geological geophysical model is established, and the reservoir distribution law is described in detail by combining the results of reservoir rock experiment analysis. Through this research work, a set of research techniques suitable for seismic sedimentary microfacies in this area have been explored. Firstly, the typical geological bodies in Yingtai area (such as distributary channels, estuarine dams, etc.) have been studied on the relation between geology and geophysical response. Then, under the guidance of forward modeling results, seismic facies (seismic reflection configuration), single well facies and seismic attributes are studied. Finally, the distribution characteristics of seismic sedimentary microfacies are comprehensively studied under the constraints of macroscopic paleogeomorphology. A better understanding of the sequence division and correlation of the Heidimiao reservoir in Yingtai area has been obtained, and the reservoir development characteristics of the Heidimiao reservoir in the Yingtai area have been clarified. This result has a certain guiding effect on the further exploration and development of this area.
