Physical Properties Research on the Eastern Part of Ordos Basin
Based on drilling-related information and logging data of 5 straight two-dimensional lines to research physical properties of the formation of the eastern part of Ordos basin.This paper analyzes formations of 10 groups(from the Triassic of Yanchang group to the Paleozoic of the Ordovician Majiagou Formation),and calculates formations'density and study the distribution.The results indicate that the study area's formation dump west,and parts of it inclines to northwest direction,while the formation don't change a lot from north to south.Little size anticline and syncline zones are separately developped in Ganquan area and Yanchang area.There is also a low density zone in Yan'an area.Those areas above constitute a typical oil-gas accumulated belt.
