鄂尔多斯盆地下古生界石油地质特征及其勘探远景

The Geologic Characteristics Of Petroleum Of Lower Palaeozoic In Ordas Basin And Its Prospect Of Exploration

本文重点论述下古生界石油地质特征。下古生界地层为一套巨厚的碳酸盐岩沉积,目前己在奥陶系获得高产工业气流。因此,鄂尔多斯盆地下古生界海相沉积区有着广阔的找气前景。

This paper mainly introduces the geologic characteristics of Petroleum of lower Palaeozoic in Ordas Basin. Ordas Basin is a large repeat-basin, which meagered from the original basins of different types. A set of marine carbonate rocks are deposited in this basin. Richness in natural reasources of oil and gas has been verified by drilling wells. The oil-gas prospecting is potential in marine deposit region of the lower Palaeozoic in Ordas Basin.
