Abstract

The invention belongs to the technical field of petrochemical engineering, and discloses a novel shale organic matter swelling oil quantification method and an experimental device thereof, and experimental device preparation, sample preparation, experimental early-stage preparation, swelling experiment and experimental data processing are carried out. The method comprises the following steps: performing kerogen enrichment on shale samples in different maturity stages, performing a swelling experiment on the enriched kerogen samples with different maturity degrees, calibrating and optimizing swelling model parameters according to a swelling ratio obtained by the experiment, and further predicting the swelling crude oil amount of the kerogen with different maturity degrees by using crude oil family components. According to the method, the swelling models of the kerogen with different maturity degrees are established based on the swelling experiments of the kerogen with different maturity degrees by virtue of an experimental method, so that the swelling oil amount of the kerogen under different maturity degrees is determined, the swelling oil amount of the kerogen can be obtained more accurately, and the method is more in line with the actual geological condition; and help is provided for continental facies shale oil resource evaluation in China.

Description

technical field

[0001] The invention belongs to the technical field of petrochemical industry, and in particular relates to a new method for quantifying shale organic matter swelling oil and an experimental device thereof, in particular to a method for evaluating the amount of kerogen swelling oil with different maturity by using the height method. Background technique

[0002] At present, shale oil exploration and development is considered to be an important strategic measure to solve the shortage of oil and gas resources. my country's shale oil resources are also very rich and have great prospects for exploration and development. The amount of shale oil resources is closely related to the hydrocarbon retention capacity of shale. The hydrocarbon retention capacity of shale can be divided into two parts: the hydrocarbon retention capacity of kerogen and the hydrocarbon retention capacity of inorganic minerals. The organic hydrocarbon retention capacity includes the hydrocarb...
