Problems solved by technology

However, after oil and gas enter the high evolution stage, the composition characteristics of common biomarkers (including paraffins and steranes, etc.) of crude oil, reservoir bitumen and source rocks tend to be consistent, and there is little useful information on organic matter residues. Lost the significance of indicating the characteristics of the original source, it is difficult to be used for fine oil-source correlation, so it cannot be effectively used for hydrocarbon source correlation

Embodiment Construction

[0029] The present invention will be further described below by specific examples, but it should be understood that the scope of the present invention is not limited thereto. In the present invention, unless otherwise mentioned, all the reagents, instruments and conditions commonly used in the art are used.

[0030] The invention relates to an element geochemical method for hydrocarbon source comparison. The method comprises collecting source rock samples and reservoir asphalt samples, and obtaining the contents of trace elements and rare earth elements in the source rock samples and reservoir asphalt samples.

[0031] Specifically, for a source rock sample (for example, 5 g), the source rock sample is washed with deionized water and an organic solvent. Wherein, the organic solvent used for cleaning includes at least one of dichloromethane, ethanol and acetone, preferably dichloromethane. Then, use a mortar to grind the source rock sample to 150-250 mesh, preferably 180-230 m...

Abstract

The invention provides an elemental geochemical method for hydrocarbon source correlation. The method includes the following steps that 1, a source rock sample and a reservoir pitch sample are collected, and detection results of inorganic element geochemical components in the source rock sample and the reservoir pitch sample are obtained; 2, according to the detection result of the inorganic element geochemical components in the source rock sample, an evaluation model is set up for the source rock sample; 3, the detection result of the inorganic element geochemical components in the reservoir pitch sample and the evaluation model set up according to the source rock sample are compared to obtain the hydrocarbon source of the reservoir pitch sample; 4, the hydrocarbon source of the reservoir pitch sample is judged. The method provides a reference for ancient oil and gas reservoir system research.

Description

technical field [0001] The technology relates to the research field of oil and gas geology and geochemistry, and specifically relates to an element geochemical method for hydrocarbon source comparison. Background technique [0002] Hydrocarbon source correlation is an important content in the current study of oil and gas systems. Its purpose is to find out the source of oil and gas, to study the formation and evolution process of oil and gas systems, and to provide references for oil and gas geological research and exploration. [0003] Organic source correlation refers to the correlation between hydrocarbons (such as oil, gas and reservoir bitumen, etc.) and the source (source rock). To clarify the process of hydrocarbon migration and accumulation, and then to predict the location of source kitchens and satellite oil and gas reservoirs. This is a key issue in formulating oil and gas exploration and development plans, so it has important theoretical significance and applica...
