松辽盆地梨树与德惠凹陷地震地层的划分对比
|
摘要
根据梨树、德惠凹陷主要地震反射层特征，结合凹陷内钻井所揭示的地质资料，通过对两个凹陷内地震反射层的追踪对比，在凹陷内共划分出７个反射层。由于两个凹陷相互毗邻，同处于松辽盆地南部，因此，它们的发生、发展受到相同地壳运动因素的控制，造成了它们在构造演化及沉积史上具有相似性。依据地质－地震综合方法进行了两个凹陷内地层划分对比，最终得出了梨树与德惠凹陷地层对比结果。
To divide the depression into seven seismic reflection layers according to the main seismic reflection nature and well-drilling data of Lishu and Dehui depressions. Since the two depressions are close to each other and located in the south of Songliao basin, there occurring and development are controlled by the same crustal movement. This result is similar to the tectonic and deposit evolution history of the two depressions,according to geological-seismic synthetic analysis method. Lastly we point out the stratigraphic division and correlation result of Lishu and Dehui depressions.
