Title:
CRUDE OIL PSEUDOCOMPONENTS, ACQUISITION METHOD THEREOF, AND AIR INJECTION RESERVOIR DEVELOPMENT DETERMINATION METHOD BASED ON CRUDE OIL COMPONENT ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2023/123977
Kind Code:
A1
Abstract:
The present invention provides crude oil pseudocomponents, an acquisition method thereof, and an air injection reservoir development determination method based on crude oil component analysis. A first crude oil pseudocomponent is formed by mixing, within a narrow distillate group of a target crude oil, each narrow distillate which has an oxidation rate with a negative temperature coefficient interval and which is fluid at the temperature of a reservoir. A second crude oil pseudocomponent is formed by mixing, within a narrow distillate group of the target crude oil, each narrow distillate which has an oxidation rate without a negative temperature coefficient interval and which is fluid at the temperature of the reservoir. A third crude oil pseudocomponent is formed by mixing, within a narrow distillate group of the target crude oil, each narrow distillate which has an oxidation rate with a negative temperature coefficient interval and which is not fluid at the temperature of the reservoir. A fourth crude oil pseudocomponent is formed by mixing, within a narrow distillate group of the target crude oil, each narrow distillate which has an oxidation rate without a negative temperature coefficient interval and which is not fluid at the temperature of the reservoir.
