层序地层学在隐蔽圈闭预测中的应用——以松辽盆地南部为例
|
摘要
根据松辽盆地南部地区典型的反演地震剖面及典型井的体系域、层序的发育特征,在松辽盆地南部地区共识别出9个层序、12个体系域,并应用层序地层学理论对松辽盆地南部地区青山口组及姚家组隐蔽圈闭进行了预测。研究结果表明:砂岩透镜体岩性圈闭主要分布于青二段及姚二三段高水位体系域;砂岩上倾尖灭岩性圈闭主要分布于姚一段水进及高水位体系域;地层超覆圈闭主要分布于各个水进体系域;断层岩性圈闭和构造岩性圈闭可以分布于各个体系域,分别取决于断层和构造发育层位。
Based on the development characters of sequences in typical inversion seismic sections and wells of Songnan region, nine sequences and twelve system tracts are identified.Under the direction of the theory of sequence stratigraphy,by applying the technology of seismic inversion constrained by well combing with data of well log and core, the authors predicted subtle traps. The results of researches indicate:sandstone lens-shaped lithology trap mainly distributed in highstand system tract of member 2 of Qingshankou Formation and member 2 and 3 of Yaojia Formation; sandstone updip-pinch-out lithology traps mainly distribute in transgressive system tract and highstand system tract of Yao1 section; stratigraphy overlap traps mainly distribute in transgressive system tracts; structure-lithology traps and fault-lithology traps can be seen in every system tracts, which depends on the development of structures and faults.
