Analysis of Lithologic Reservoir Exploration in Dainan Formation of Lianmengzhuang Area

基于地震、钻井、录井及测井等资料 ,建立了高邮凹陷第三系至白垩系泰州组层序地层框架 ,划分出 2个一级层序、 4个二级层序、 11个三级层序 ,将戴南组划分为SⅢ5、SⅢ6、SⅢ7共 3个三级层序和 8个体系域。通过地震精细解释 ,研究区无有效的构造圈闭 ;利用地震反演技术 ,对研究区储层进行了预测 ,落实了 13个岩性圈闭 。

Based on seismic, drilling and logging data, a sequence stratigraphic formation framework of Taizhou Formation from Tertiary to Cretaceous in Gaoyou Depression is established. Two primary sequences, four secondary sequences, eleven third sequences are classified. Dainan Formation is divided into 3 sequences of S III 5 , S III6 and S III7 and 8 system tracts. Precision seismic analysis shows that there are not any effective structural traps in the studied area. The reservoirs in the area are predicted by using seismic inverse technique, by which 13 lithologic traps are determined. Oil and gas bearing situations of the traps are demonstrated through drilling and exploration.
