Abstract

Abstract

The pressure characteristics of Mesozoic oil reservoirs in Ordos Basin was studied for the first time. It is found that the Mesozoic oil reservoirs are mainly ultra-underpressured ones and the abnormal underpressure difference in oil reservoirs among different regions and different layers is distinct. The results show that oil reservoir pressure coefficients exhibit a decreasing trend with the increase of eroded strata thickness and temperature drop value of oil reservoirs after, and the reservoir porewater volume contraction amounts to 0.82%-1.94% as a result of temperature drop after uplift of Yanchang Formation oil reservoirs, which indicates that the function of strata erosion and paleotemperature decrease due to long time and strong uplift of the basin at the end of the Cretaceous result in the formation of underpressured oil reservoirs. The underpressured closed system of Mesozoic in the Ordos Basin is believed to be advantageous for oil reservoir preservation and may have played an important role in oil reservoir adjustment, re-enrichment of hydrocarbon by migration and oil and water distribution in oil reservoirs. It is concluded that Chang-6 underpressured reservoir enriched from the southeast to the northwest in the North Shaanxi area and presence of Chang-7 lenticular sandstone body reservoirs with absence of water are closely related to the distribution of such underpressured closed systems.
