摘要
原有对宝中背斜构造断层特征的认识已不能满足油气勘探开发的要求,利用钻井、测井、地层对比、地震等资料,对宝中区块断层特征进行再认识。研究表明:首次在本区利用多种地震信息技术(三维数据体、相干数据体、倾角切片以及时间切片等)进行综合解释取得了较好的效果,共解释出14条不同级别(Ⅰ、Ⅱ、Ⅲ级)的断裂,将原有F4、F13和F6、F7断层分别认定为同一条断层,新增识别Ⅲ断层5条,同时对不同级别的断层特征进行了描述。最终分析认为Ⅰ级断层对背斜形成、展布特征以及油气聚集具有控制作用,Ⅱ级断层对背斜形成有影响,同时控制着油气水分布,Ⅲ级断层使油水关系及油层分布特征更加复杂。
The original understanding can not meet the requirements of oil and gas exploration and development,the fault features at the Baozhong anticline structure,based on the drilling,logging,stratigraphic correlation,seismic data et al,the fault features at Baozhong block are recognitioned. After study： using a variety of seismic interpretation technology（ 3D,coherent data volume,dip angle and time slice） for interpretation have been achieved good results,explain the 14 different level faults（,Ⅱ,Ⅲ）,The original F4,F13 and F6,F7 faults respectively as the same fault,Identify 5 new Ⅲ faults,then describes the fault characteristics of different levels. Finally it is concluded that Ⅰ faults control anticline structure form,distribution and oil and gas accumulation,Ⅱfaults affect the formation of anticline and water distribution of oil and gas,Ⅲ faults complicate the reservoir distribution and oil-water relationship.
