Abstract

Background:

Three-dimensional geological modeling of reservoirs is not only the key factor for reservoir description and prediction of oil reserves but also an important means of quantitative characterization of reservoir geometry and heterogeneity in three dimensional spaces. The aim of this paper is to establish prediction model for sandstone classification and reservoir petrophysical properties.

Methods:

Sand body prediction model was built by using stochastic simulation of discrete variables. Gauss model and sequential Gauss simulation method were selected to build porosity, permeability and oil saturation models.

Results:

The Chang 812 layer includes three sedimentary microfacies: distributary channel, inter-distributary bay and swamp. The dominant thickness of Chang 812 layer ranges from 15 to 20m. Three other classes of thickness (5-10 m, 10-15 m and 0-5 m) are subsequently less present. The major porosity of Chang 812 layer ranges from 5 to 15%, the major permeability ranges from 0.1 to 2×10-3μm2 and the major oil saturation ranges from 55 to 70%.

Conclusion:

The Chang 812 layer of Triassic Yanchang Formation mainly formed in braided delta plain depositional environment. The truncated Gauss simulation of sand body was applied in simulation. The thickness of the sand body is relatively greater than the porosity, permeability and oil saturation values.

Keywords: Reservoir modeling, Sandstone, Porosity, Permeability, Saturation, Ordos Basin.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
