Description

Technical Field

[0001] The invention relates to the technical field of petroleum hydrocarbon sampling, in particular to an intelligent petroleum hydrocarbon sampler system. Background Art

[0002] Petroleum hydrocarbons refer to hydrocarbon compounds in oil. Hydrocarbons, or hydrocarbons, account for the vast majority of petroleum, about tens of thousands of species, without obvious overall characteristics, mainly composed of hydrocarbons, and the structure and proportion of various hydrocarbons vary greatly. In terms of the composition of petroleum geology, the structure is very complex. It mainly includes saturated and unsaturated hydrocarbons, aromatic compounds, asphaltene, resins, etc.

[0003] Petroleum hydrocarbons are one of the organic pollutants commonly found in the environment. According to incomplete statistics, during the process of oil extraction, transportation and use, the amount of crude oil leaked due to various reasons is as high as 10 million tons per year, and the various oily wastewater discharged during oil field extraction is as high as 30 million tons. At present, the serious threats caused by petroleum hydrocarbons to nature and ecology are mainly divided into two categories: one is alkanes, and the other is aromatic hydrocarbons and polycyclic aromatic hydrocarbons. Petroleum hydrocarbon pollution is one of the most prominent environmental problems in my country. By analyzing the water samples of a certain water area, we can know whether the water area is polluted by petroleum hydrocarbons. By analyzing the petroleum hydrocarbon content in the soil, we can reveal the impact of petroleum hydrocarbon pollution. By measuring the petroleum hydrocarbons in sediment samples, we can obtain the results of atmospheric dust in various periods, as well as the baseline value before the discharge of petroleum pollutants caused by human activities and the results of petroleum pollution caused by different reasons. Therefore, it is very important to analyze the content of petroleum hydrocarbons in the environment and study how to effectively detect them, which has also become a primary issue in soil environmental monitoring.

[0004] At present, during the testing and debugging process, short-circuiting is performed using short-circuit wires. Simulation testers need to short-circuit the circuit, which poses a risk of electric shock. Frequent short-circuiting of equipment poses a high safety risk to the equipment. At the same time, frequent short-circuiting of equipment can easily cause inherent hidden dangers in the equipment. The operator has to maintain the same posture in the 200V control box, which is time-consuming and laborious, and can easily lead to misoperation. The operation process is dangerous.

[0005] The monitoring of petroleum hydrocarbon content must collect appropriate soil samples at the site to be tested. Soil sampling refers to the method of collecting soil samples, including the layout and sampling technology of the samples. At present, soil sampling has the following problems:

[0006] 1. The lighter components in petroleum hydrocarbons are volatile. If appropriate storage and transportation methods are not adopted, the authenticity of the measurement data will be seriously affected;

[0007] 2. It is difficult to identify samples on site, and handwritten labels are usually used. This is prone to errors when a large number of samples are collected;

[0008] 3. Repeated data entry: In both sampling site and laboratory testing environments, sample information needs to be entered multiple times, reducing work efficiency;

[0009] 4. After the instrument is tested, it needs to be manually entered into the relevant system again, and the traceability of the test results cannot be guaranteed;

[0010] 5. There is no corresponding interface for the digital platform. The testing instruments of various manufacturers work independently. Most of them do not provide secondary development interfaces or data export hardware interfaces, making it impossible to automatically read data or directly connect to the central digital platform.
