摘要
从地震、高分辨率层序地层对比、沉积相方面研究认为,石南21井区与石南4井区头屯河组地层的可对比性较高、岩相组合相似、沉积微相相近,两井区有连片的可能性;从油水两相渗流实验、地层原油密度的差异对石南地区进行了复算油水过渡带厚度及油水界面高程差,结果表明,石南21井区与石南4井区有可能为同一油藏。
Based on seismic,sedimentary facies analysis and high resolution stratigraphic sequence correlation,it is considered that Toutunhe formation in Shinan-21 wellblock and Shinan-4 wellblock have similar facies association and sedimentary microfacies.And it is possible for the two wells to connect.We recalculate the thickness of the oil-water transitional zone and the elevation difference of oil-water interface in Shinan areas according to the experiment of oil-water two phase seepage flow and the study on difference of formation crude oil density.It is demonstrated that Shinan-21 wellblock is likely to come from same source rock as Shinan-4 wellblock.
