渤海中部馆陶组层序地层特征及其底界研究
|
摘要
通过以岩电性、古生物、地震层序为基础的层序地层学研究,结合区域研究资料,在馆陶组识别出低位、水进和高位三种体系域;利用基准面旋回技术识别出短期基准面旋回(SSC)、中期基准面旋回(MSC)和长期基准面旋回(LSC);馆陶组划分为2个长期基准面旋回,4个中期基准面旋回MSC1～MSC4,建立了渤海中部馆陶组及东上段高分辨率等时地层对比格架。D5-1井2782～2917m井段确定为东一段地层,其顶界即为馆陶组的底界。通过对馆陶组底界的确定和区域馆陶组及东上段高分辨率层序地层等时对比格架的建立,对该区馆陶组底界进行了重新厘定,目的为解决油气勘探中遇到的问题。
The sequence stratigraphy of the Guantao Formation was investigated by integrating lithostratigraphic,well log,paleontological,and seismic stratigraphic data.Three system tracts,LST(low-stand system tract),TST(transgressive system tract)and HST(high-stand system tract)were recognized.Base on base-level cycle analysis,three kind of base-level cycles(SSC:short-term baselevel cycle sequence;MSC:medium-term baselevel cycle sequence;and LSC:long-term baselevel cycle sequence)in Guantao Formation were recognized.The Guantao Formation is divided into two LSCs and four MSCs(MSC1 to MSC4).The depth of 2782 to 2917 meter of the D5-1 well belongs to the Dongying Formation,whose upper boundary marks the base of the Guantao Formation.Ascertaining the lower boundary of the Guantao Formation and a detailed sequence stratigraphic investigation of the Dongying Formation provide important stratigraphic basis to support the oil and gas exploration in the middle Bohai Bay Basin.
