摘要
通过对研究区已钻井分析统计,证实河道砂体和微幅度构造圈闭合理配置形成的圈闭为最有利的勘探目标。研究区构造圈闭落实程度高,面积大于0.1 km^2,幅度大于3 m的构造圈闭内基本都有井钻探。为了寻找更多的有利井位目标,分析对比研究区内两口出油井的构造圈闭特征、岩性物性特征、采油强度,通过多信息的协同分析论证,认为河道砂体和构造背景合理配置能形成岩性-构造复合圈闭。根据以上认识,针对此类型钻井,最终钻井获得高产,扩大了该区勘探领域。
Through the analysis and statistics of the drilling in the study area,it is confirmed that the trap formed by the rational arrangement of the channel sand body and the micro-amplitude structural trap is the most favorable target.In the study area,the structural traps are highly encountered,and the area is larger than 0.1km^2,and the structural traps with seismic amplitudes greater than 3m basically have well drillings.In order to find more favorable well positions,the structural trap characteristics,lithological physical characteristics and oil production intensity of the two oil wells in the study area are analyzed and compared.With the collaborative analysis of multiple data,it is considered that the channel sand body and the structural background can form lithologic-structural composite traps.Based on the above understanding,for this type of drilling,the final drilling has achieved high-yield oil flow and expanded the exploration area of the field.
