Detailed Description
The present application is described in further detail below with reference to fig. 1-4.
In order to accurately find the condition of an oil well and provide effective information for workers to find a water flooded layer and evaluate the oil and gas properties in time for the possibility of oil and gas containing in a logging abnormal well section, the water-bearing property of a reservoir and the degree of secondary oxidative bacterial degradation of hydrocarbons, and the like, in the related technology, the C1-C5 monomeric hydrocarbon is explored, and the related data of the C6-C8 monomeric hydrocarbon is developed, wherein the related data comprises the components and the proportion of the C6-C8 monomeric hydrocarbon and the parameters and indexes formed by combining the data.
Therefore, the application provides a continuous light hydrocarbon chromatographic analysis method, which can be used for identifying and analyzing C6-C8 monomer hydrocarbon existing in an oil well, can quickly and periodically provide effective C6-C8 related data, and is convenient for workers to check information of the current well section of the oil well.
The embodiment of the application discloses a continuous light hydrocarbon chromatographic analysis method, which comprises the following steps with reference to fig. 1:
s100: and obtaining a pure sample gas.
The pure sample gas refers to a pure gas from which impurities are removed. In the embodiment of the application, the sample gas in the oil well needs to be collected firstly, and then the collected sample gas is subjected to purification treatment and distribution. The purification treatment is to form pure sample gas from the collected sample gas and then output the pure sample gas. Dispensing is understood here to mean dividing the purified sample gas into a plurality of portions for subsequent processing.
S200: and (5) a pure sample gas separation step.
Because the gas composition in the oil well is more, and the analysis is mainly used for obtaining the composition ratio of C5-C8 in the sample gas, the separation is needed. In the embodiment of the application, a chromatographic column is used for separating pure sample gas, and a plurality of monomer hydrocarbon gases are obtained and output.
The various monomeric hydrocarbon gases, C1-C5 monomeric hydrocarbons, separated here can be analyzed by other prior art equipment and the results exported, while the C6-C8 monomeric hydrocarbons need to be processed before further analysis.
S300: and (4) identifying the monomer hydrocarbon.
In order to analyze the components, the proportion and other related data of the monomer hydrocarbon more quickly, the step is to output mixed gas after mixing the monomer hydrocarbon gas with preset gas in a real-time process; and then identifying the data of the mixed gas, outputting the data of the mixed gas, and simultaneously outputting various combined parameters, indexes and the like, thereby facilitating the analysis of the next step.
S400: and (4) analyzing the monomer hydrocarbon.
This step first requires the acquisition of the plurality of data generated and output in step S300, followed by analysis.
Since the time required for the identification step of the monomer hydrocarbon is long, in order to realize the periodic output data of 60S, in the embodiment of the present application, when the analysis is performed in step S400, the next group of mixed gas is subjected to the identification of the monomer hydrocarbon in step S300, so that the time for outputting the analysis data can be saved, and the periodic output data can be formed.
When data of the mixed gas is periodically acquired, the peak height, the minimum peak area and the minimum fluctuation of the mixed gas need to be analyzed and determined. And then determining the peak height, the minimum peak area and the minimum fluctuation of the mixed gas as sample data, acquiring and outputting the peak time of the monomer hydrocarbon from the sample data, and analyzing and outputting the peak data according to the peak time.
Further, the specific steps of S100 are as follows:
s101: and (4) degassing. Since the gas in the well is contaminated with various impurities and some other gas not intended to be detected in this application, etc., after the drilling fluid has been obtained, it is common to treat the obtained drilling fluid via a degasser, which outputs the gas after the treatment. It is to be understood that the gas output here comprises mainly monomeric hydrocarbon gas as well as part of the other gases, i.e. the gas after the preliminary treatment is obtained in this case.
S102: and (5) filtering. The degasser outputs gas, inputs the gas into the filter element, forms pure sample gas after filtering the gas by the filter element, and outputs the pure sample gas.
It should be understood that the filter element described herein may be one of a variety of gas filters, and in particular, may be used by those skilled in the art with the appropriate filter element selected for the actual filtering needs, as is well known in the art.
The step S300 comprises the following steps:
s301: and acquiring mixed gas.
Mixing pure sample gas with hydrogen, igniting and burning under the combustion supporting of air and other gases, and generating and outputting new gas in the burning process. Wherein, hydrogen is the setting gas set in the embodiment of the application, and the technicians in the field can also set according to the detection requirements.
The step of mixing the pure sample gas and the hydrogen comprises the step of mixing two parts of pure sample gas with the hydrogen respectively, wherein the proportion of the two mixed gases is different, so that the output related data is not completely the same, the subsequent identification and analysis steps are more convenient, and the analysis data can be more comprehensively obtained.
S302: and identifying new gas.
The new gases generated by combustion were obtained and the data for the monomeric hydrocarbons identified by the identifier in the examples of this application. It should be understood that the data of the monomeric hydrocarbon as used herein only refers to information such as the ratio of the individual monomeric hydrocarbons. Authentication by an authenticator is also a well known technique to those skilled in the art and will not be described in detail here.
S400 comprises the following specific steps:
s401: a first set of mixed gas data is acquired.
Because two groups of components are set for analysis when identifying gas composition data, one group is firstly used for analysis. The analysis here consists essentially of determining the peak height, minimum peak area and minimum fluctuation of the mixed gas. And then determining the retention time, and acquiring and outputting the peak-appearing time of the monomer hydrocarbon within the retention time so as to obtain the relevant data of the monomer hydrocarbon.
S402: a second set of mixed gas data is acquired.
After the first group of mixed gas data is analyzed and an analysis result is output, acquiring a second group of mixed gas data, analyzing and determining the peak height, the minimum peak area and the minimum fluctuation of the mixed gas in the same way as the first group of mixed gas data; and determining the retention time, and acquiring and outputting the peak time of the monomer hydrocarbon within the retention time.
It is noted that, in general, a time required from the identification of one set of data to the analysis of the data is about 120s, and in order to form a 60s cycle, the first set of mixed gas is subjected to 60s before the identification and analysis of the second set of data is started. The periodic collection, separation, identification and analysis are carried out by taking the cycle as a period.
More importantly, the collection and the data identification analysis are separately performed, namely, the collection is performed by the lower computer, and the data identification analysis is performed by the upper computer, so that the collection and the data identification analysis can be performed independently, and the aim of periodically outputting identification analysis data can be conveniently fulfilled.
