胜利油区基岩潜山储集体分布预测技术及应用
|
摘要
胜利油区基岩潜山储集体发育的控制因素较复杂,造成储层储集空间类型多样,空间非均质性极强,分布预测研究难度很大。目前主要应用的预测技术有:基于控制因素分析的地质预测技术、应力场分析技术、相干体分析技术、地震测井联合反演技术和多尺度边缘检测技术等,其原理与适用条件有较大的差异。在对技术进行适应性分析的基础上,提出针对基岩潜山这种复杂储集体,应根据具体研究对象的不同储集类型和资料条件,选取合适的多种预测技术进行综合预测,从而提高储集体预测的精度。
The description and characterization of reservoir geometrical morphology is the key and difficult point for base and buried mountain reservoir.Compared with the same burial hill home and abroad,the buried mountain reservoirs in Shengli oilfield are more complex in controlling factors.Therefore the reservoir space form is variety and very heterogeneous,and it is difficult for the study of prediction.The techniques used in the prediction mainly consist of geological prediction based on controlling factor analysis,stress field analysis,coherent body analysis,multi-scale boundary testing method and seismic reversion constrained by logging technology,which are different in mechanisms.Based on the analysis of the application and feasibility of the techniques above,a comprehensive prediction technology for the complex base and buried mountain reservoir was proposed according to the certain object,and verifying mutually so as to improve the accuracy of the prediction.The method and technology have been successfully applied in the field and with good performance,which offer a geological foundation for the base and buried mountain reservoirs.
