Embodiment Construction

[0062] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0063] The present invention is illustrated by taking Tarim Basin oil and gas reservoirs as an example:

[0064] 1) Take 200mg crude oil sample in 2mL autosampler bottle, add 0.5μg / μL D 16 - 40 μL of adamantane standard sample, after mixing evenly, add dichloromethane to 1.5 mL.

[0065] 2) The crude oil samples were analyzed by a comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometer (GC×GC-TOFMS) produced by Leco Company of the United States. The adamantane series compounds are identified and identified, and the peak information of each compound is obtained, such as Figure 2a-Figure 2f It...

Abstract

The invention discloses a method for determining the cracking degree of crude oil. The method includes the following steps: S1. Using a comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometer GC×GC-TOFMS to identify and identify ethyl noradamantane series and methyl bisamantane series compounds in multiple crude oil samples, and obtain Peak information of each compound; S2, quantitative analysis of ethyl noradamantane series compounds, to obtain the content of ethyl noradamantane series and methyl bisamantane series compounds; S3, fitting ethyl noradamantane series compound content and (4-+3-) Relational formula between methyl bis-adamantane; S4, establish the relationship between (4-+3-) methyl bis-adamantane and crude oil cracking degree; S5, determine crude oil cracking degree. The method of the invention can determine the cracking degree of crude oil only by relying on a small amount of crude oil samples, judge the cracking window of deep oil and gas, further evaluate the amount of deep oil and gas resources, and guide exploration and development.

Description

technical field [0001] The invention belongs to the technical field of petroleum sample analysis, and in particular relates to a method for determining the cracking degree of crude oil. Background technique [0002] Crude oil cracking is ubiquitous in deep oil and gas reservoirs, and the degree of crude oil cracking reflects the degree of conversion of crude oil to natural gas after undergoing a high evolution stage in geological bodies. Crude oil cracking gas can be used as an important source of natural gas, and it is also an important direction for future natural gas exploration. Early studies believed that temperature is the only factor affecting the cracking of crude oil, but it is not accurate enough to evaluate the original cracking degree only by temperature. With the deepening of research, the (4-+3-) methyl bis-adamantane index proposed by Dahl et al. and ) are promoted for use. [0003] Comprehensive two-dimensional gas chromatography (GC×GC) is a new analytica...
