Problems solved by technology

[0008] The above-mentioned methods are all based on a single index of source rocks, and a large amount of analysis and testing work is required for each source rock sample, or the qualitative evaluation or relative evaluation of source rocks, or the evaluation of source rocks. The component division is not detailed enough

Embodiment 1

[0045]This embodiment provides a method for evaluating the hydrocarbon generation potential of a source rock. The method includes the following steps:

[0046]101) Select a source rock to obtain the total organic carbon (TOC) of the source rock.

[0047]102) First, use manual selection to select the organic microscopic components in the source rock; prepare kerogen for the remaining part of the source rock selected by the manual selection method; prepare the cheese Roots are crushed into powder samples below 100 mesh. The density solution is a mixture of iron metatungstate and ethanol; increasing the content of iron metatungstate in the density solution increases the density gradient of the density solution, thereby reducing the organic content in the kerogen. The microscopic components are separated one by one according to the density of the organic microscopic components from light to heavy, and then each separated microscopic component is collected, cleaned and dried to obtain each org...

Embodiment 2

[0055]Using the method provided in Example 1 to evaluate the hydrocarbon generation potential of source rocks, the Tertiary oil shale H5 in a basin in eastern China was used as the experimental object. The oil shale has a TOC of 5.07% and a maturity of about 0.5%.

[0056]Step 1. Preparation of single microscopic component.

[0057](1) Sample selection and pretreatment: select a certain oil shale sample A1 rich in layered algae (TOC=24%, the content of layered algae in organic matter is greater than 81%), resin coal A2 (TOC about 70%) , The naked eye can see granular resin bodies and vitrinites are generally distributed), keratinous coal A3 (TOC about 33.8%, keratinocytes and vitrinites are distributed in layers), a sample of Staphylococcus rich in A4 (TOC about 11.8%), etc. The samples were enriched for a single microscopic component.

[0058](2) Sample separation method: Because the resin body is visible to the naked eye, manual selection is used for separation. The layered algae, vitrinit...

Abstract

The invention belongs to the technical field of oil and gas geochemistry, and relates to a method for evaluating hydrocarbon generation potential of hydrocarbon source rock. The method comprises the following steps that S1, selecting hydrocarbon source rock, and obtaining the total organic carbon amount of the hydrocarbon source rock; S2, separating a plurality of organic microcomponents in the hydrocarbon source rock to obtain each organic microcomponent in the hydrocarbon source rock; S3, performing a rock pyrolysis experiment on each organic microcomponent to obtain the hydrocarbon generation potential of each organic microcomponent; S4, calculating the proportion of each organic microcomponent in the plurality of organic microcomponents; and S5, calculating the product sum of the hydrocarbon generation potential of each organic microcomponent and the proportion of each organic microcomponent in the plurality of organic microcomponents, and the product of the product sum of the hydrocarbon generation potential of each organic microcomponent and the total organic carbon amount of the hydrocarbon source rock, so as to obtain the hydrocarbon generation potential of the hydrocarbonsource rock. The method is simple and rapid to operate and suitable for screening a large number of samples.

Description

Technical field[0001]The invention belongs to the technical field of oil and gas geochemistry, and more specifically, relates to a method for evaluating the hydrocarbon generation potential of a source rock.Background technique[0002]Hydrocarbon source rock refers to any kind of fine-grained sediment that has been generated and discharged enough to form commercial hydrocarbon accumulation in the natural environment. In principle, any rock contains more or less organic matter, so it has the ability to generate a certain amount of oil and gas. However, not all rocks containing organic matter are source rocks, and only rocks that have contributed to accumulation can be called source rocks. When conducting early geochemical research on an unexplored area, people often do not know in advance whether the formation in the area has produced and discharged commercial oil and gas, but the research is still called source rock evaluation.[0003]Source rock evaluation usually includes the evaluati...
