摘要
利用现代沉积学理论结合测井和地震等资料,对郑家王庄地区砂砾岩扇体特征研究后认为:郑家王庄地区在下第三系以形成沙一、沙三、四段的较高水动力能砂砾岩扇体(冲积扇、扇三角洲、近岸水下扇)沉积体为主,其中沙三上亚段扇三角洲砂砾岩体是本区最主要的砂砾岩扇体类型,并具有较好的储集性能,是区内最主要的油气储集体;郑家王庄地区砂砾岩扇体沉积,强烈地受制于边界构造条件;其砂砾岩扇体沉积及其形态均受沉积相的控制,并具有复杂多变的特征,从而直接导致了本区油气藏的聚集和分布具有复杂多变的特点。
Sedimentology, logging and seismic exploration data are used to study the gultenite fan body characteristics in Wangzhuang area. It is considered that high hydrodynamic energy glutenite fan body of Es1, Es3 and Es4 section of Taleogene system are mainly formed in Taleogene period and fan-delta glutenite is the major fan body type in this area. They have good reserve function and are major oil and gas reserve body in this area. Glutenite fan body in Wangzhuang area is strongly controlled by boundary tectonic condition. Fan body and its occurrence is controlled by sedimentary facies. It has complicated characteristics of oil and gas concentration and distribution.
