Description
Technical Field
The invention relates to the technical field of petroleum and natural gas exploration, in particular to a canned sample gas taking device for a petroleum and natural gas exploration laboratory.
Background
In oil and gas exploration, the identification and evaluation of an oil and gas water layer are one of important links in oil and gas exploration and development work, and the application of new logging technology has recently attracted more and more attention from domestic and foreign specialists and scholars. In recent years, along with the gradual deep exploration of oil fields, the objects of resource exploration are more diversified, including shale gas, coalbed methane and the like, the oil-gas-water relationship of exploration blocks is more and more complex, and higher requirements are put forward on the oil-gas reservoir identification and evaluation technology. Especially, the judgment difficulty of the light oil layer, the residual oil layer, the high mud-containing reservoir and the volcanic gas-water layer is higher, and the requirement of fine evaluation cannot be met only by means of the conventional single logging technology for qualitative interpretation of the oil-gas layer. Through the continuous efforts of a large number of logging workers, the logging has moved from the traditional logging to a new stage of modern comprehensive evaluation logging, forms a new modern logging technology integrating on-site data acquisition, data, processing and hydrocarbon reservoir interpretation and evaluation, and plays an increasingly important role in the exploration and development of hydrocarbon resources. Through technical innovation and development, the comprehensive logging technology, the under-lens fluorescence analysis technology, the interpretation and evaluation technology and the like are sequentially applied to the on-site logging, so that the comprehensive logging realizes the crossover development. Meanwhile, a complete set of evaluation technical systems for light oil layer, residual oil layer, high mud-containing reservoir, gas-water layer recognition evaluation and the like are formed by overcoming the technical problems of complex oil-gas-water layer recognition evaluation.
The method for quantitatively evaluating the hydrocarbon reservoir by comprehensively using the new logging technology is a very difficult problem, and not only is the application of the new technology required, but also the synthesis of multiple disciplines such as geological logging, logging and the like is required. The gas light hydrocarbon logging on the top of the tank is an important work, and the basis of the work is collection and operation work of the gas dissipated by the tank sample.
The tank top gas is a mixed gas of hydrocarbon and air which is stored in the top space of the canned rock debris (core) and reaches gas-liquid phase balance with the liquid at the lower part, wherein the hydrocarbon is naturally desorbed from the rock debris (core). The light hydrocarbon logging of the tank top gas is to inject a tank top gas sample into a gas chromatograph for analysis, so that the light hydrocarbon components of the tank top gas are completely separated, and the light logging method of the oil gas light hydrocarbon components is obtained. The top gas of the tank detects common C1-C7 hydrocarbon components in crude oil, including 7 normal paraffins, 13 isoparaffins, 8 naphthenes and 1 aromatic hydrocarbon (benzene), and 29 monomer components. Compared with the gas logging which can only detect C1-C5 hydrocarbon components, the light hydrocarbon information obtained by the gas logging on the tank top is more abundant and comprehensive. The light hydrocarbon is partially volatilized and dissipated before the rock scraps (cores) are canned, so that the light hydrocarbon in the tank top gas is substantially the result of natural desorption and dissipation of the residual light hydrocarbon after the light hydrocarbon in the rock scraps (cores) is partially volatilized. Compared with the light hydrocarbon in the original stratum, the light hydrocarbon composition (component number) of the tank top gas is basically the same, the composition of the stratum light hydrocarbon is reflected, and the abundance of the tank top gas light hydrocarbon is closely related to the abundance of the stratum light hydrocarbon and the light hydrocarbon escape and volatilization degree of the sample tank. The relative content of the light hydrocarbon in the tank top gas is the result of the combined action of the light hydrocarbon in the stratum on the physical properties of the oil layer, the property of the crude oil, the light hydrocarbon content in the crude oil, the performance of the drilling fluid and other factors. The gas-light hydrocarbon logging on the top of the tank is based on the abundance of light hydrocarbon, the composition of light hydrocarbon is used as a reference, the relative content of light hydrocarbon is used as a main basis to judge the activity degree of light hydrocarbon, then the activity degree of hydrocarbon reservoir is pushed out through the activity degree of light hydrocarbon, and finally the aim of judging hydrocarbon reservoir is achieved, so the gas-light hydrocarbon logging on the top of the tank plays a very important role in oil and gas exploration, and as mentioned above, the laboratory gas-taking work of the rock debris (core) tank sample is a key basic work because the gas-taking work is an important link, namely the quantity, affecting the analysis of the gas-light hydrocarbon on the top of the tank.
The collection of gas from a laboratory in a chip (core) can sample is a critical operation for ensuring the complete collection of light hydrocarbon components. In general, in a drainage and air extraction method used by a laboratory operator in a conventional air extraction mode, namely, a canning sample tank for collecting and canning on site is vertically arranged (the canning sample tank is stored and transported upside down after being collected on site, so as to prevent air from volatilizing from a tank cover), the canning sample tank is placed into water, a tank body is held by one hand, a plastic bag is held by the other hand, the tank cover is rotated by the hand for holding the plastic bag, and light hydrocarbon gas which is scattered from rock debris (cores) after the tank cover is unscrewed and accumulated in the top space in the tank can enter the plastic bag (because the gas is insoluble in water); then, the operator takes out the plastic bag from the water and tightens the plastic bag, then the plastic bag is pumped out of the plastic bag by the injector, and the gas is injected into the analysis equipment for detection and analysis, and the gas taking operation steps are repeated after the analysis is finished. This type of gas extraction is original and is also commonly used because there is no better method and apparatus for extracting gas from a canned sample tank. However, this gas extraction method has a number of disadvantages, which directly affect the tank top gas analysis. In summary, there are several disadvantages:
1. the plastic bag is covered, the cover is screwed to take out air, so that the plastic bag is damaged, and the air can escape into the atmosphere after the plastic bag is damaged, so that the canned sample air is wasted, the irreparable data loss is caused, and the exploration benefit is reduced;
2. clean fresh water is used for draining and taking gas, and is a waste of fresh water resources; meanwhile, plastic garbage is formed after the plastic bag is damaged, so that the environment is polluted;
3. the space volume of the plastic bag is not quantitative, so that the gas extracted by the injector cannot be quantitative, and the analysis working quality is affected;
4. after the plastic bag is drained and gas is taken out, the plastic bag is required to be contacted with air when being taken out from the water, and the gas collected in the period is required to be diluted to different degrees, so that the gas analysis quality and the oil-gas exploration benefit are affected;
5. the drill cuttings (cores) in the tank are mixed with the drilling fluid, so that when an operator unscrews the tank cover, the drilling fluid is mixed with the drill cuttings (cores) to infect fresh water, and hands are corroded after being immersed for a long time, so that occupational health of the operator is damaged;
6. the tank body is smooth, the periphery of the tank cover is provided with shallow threads, and under the condition that the tank cover is very tight, operators can hardly unscrew the tank cover, which is time-consuming and labor-consuming;
7. in winter, the temperature of water is low, and the operator can soak hands in cold water for a long time, which is more unfavorable for physical health.
In short, according to the conventional laboratory drainage gas extraction method, various possible situations can occur in the gas extraction process, and meanwhile, the necessity such as gas dilution, loss and the like also exists, and all the problems affect the scientificity and the high efficiency of the final light hydrocarbon analysis, so that the benefit of oil and gas exploration is directly affected.
