Abstract

The invention provides a collection and liquid-separation container and a method for measuring content of light hydrocarbons by the utilization of the collection and liquid-separation container. The collection and liquid-separation container comprises a housing, an internal cavity and a fluid communicating pipe. The housing comprises a cylindrical sidewall, an arc-shaped top cover and an arc-shaped bottom cap. The fluid communicating pipe contains a sample introduction tube, a gas product output tube and a liquid-separation and liquid-discharge tube. The sample introduction tube and the gas product output tube pass through and extent out of the arc-shaped top cover. The liquid-separation and liquid-discharge tube contains an upper capillary tube section, a variable diameter section and a lower liquid-discharge section. The upper capillary tube section is arranged on the outer wall of the arc-shaped bottom cap and is communicated with the internal cavity through a through hole on the arc-shaped bottom cap. According to the method for measuring content of light hydrocarbons by the utilization of the above collection and liquid-separation container, the collection and liquid-separation container is used for collection and measurement of volatile light hydrocarbons composition, and a capillary tube is used for low-temperature enclosed liquid-separation. Content of volatile components is measured at normal temperature and normal pressure in an open environment. Thus, content of volatile light hydrocarbons composition is accurately measured.

Description

technical field

[0001] The invention belongs to the technical field of oil and gas geochemistry, and in particular relates to a liquid collecting and separating container and a method for measuring light hydrocarbon content using the device. Background technique

[0002] Through the relevant quantitative chemical analysis of thermal simulation experiment products of hydrocarbon generation and expulsion, drilling crude oil samples or rock extracts, the composition and chemical characteristics of crude oil including light hydrocarbons can be obtained, which is an important tool for source rock evaluation and regional analysis in oil and gas exploration. The main way to evaluate the potential of oil and gas resources is also the main means of geochemical research to understand the mechanism of oil and gas generation, reproduce the process of hydrocarbon generation and expulsion, and understand the relationship between oil and gas sources and the law of oil and gas enrichment.
