Abstract

The invention relates to an outdoor shale gas collecting tank and method, which aim to prevent air from being mixed into shale gas to reduce the purity of the gas in an outdoor shale gas collecting process, are favorable to improve the precision of a gas experiment, and belong to the technical field of outdoor shale gas collecting experiments. The outdoor shale gas collecting tank provided by the invention is characterized in that the hemisphere shape of the top of the outdoor shale gas collecting tank can guarantee the gathering direction of gas and the collecting capacity of gas under small gas capacity, and generated gas extrude water in the hemisphere shape part to discharge the water out of a tank body through drain holes of a balance water pipe; in the whole process, a cavity is filled by water, air is not mixed through sealing, and thus the purity of gas is guaranteed; and the balance water pipe has important meaning for pressure and an exhaust process in a sample desorbing process. The outdoor shale gas collecting tank provided by the invention can guarantee that gas is gathered on the top of the tank body, air is prevented from mixing to cause a collecting error, and thus a precision result of an experiment is improved. The gas collecting tank and the gas collecting method applying the gas collecting tank provided by the invention are simple and useful, reduce collecting errors and guarantee outdoor shale gas collection and follow-up experiments.

Description

Open-air shale gas gas production jar and gas production method
Technical field
The present invention relates to a kind of open-air shale gas gas production jar and gas production method, is for fear of to sneaking into the purity that reduces gas because of air in the open-air shale gas gas production process, is conducive to improve the degree of accuracy of gas experiment, belongs to open-air shale gas gas production experimental technique field.
Background technology
Shale gas is as a kind of novel natural gas source, obtained success in the exploitation of countries such as the U.S., Canada, and China's shale gas distribution area is wide, it is many to grow series of strata, and resource potential is big, can fill up the shortage of China's conventional energy resources to a certain extent.Shale gas stores with ADSORPTION STATE and other mode in reservoir, the about 0.5-3m3/t of absorption tolerance.After the shale sample takes out under the reservoir conditions, because temperature, pressure changes, be adsorbed on the shale surface and intrapore gas generation desorb, migration, and discharge.Often reason makes air inevitably sneak into to general gas producing device because complicated operation, pipeline be too many etc., and particularly under the lower situation of shale gas tolerance, the field acquisition error is too big, has influenced experimental result.
Summary of the invention
The purpose of this invention is to provide a kind of open-air shale gas gas production jar and gas production method, solving existing shale gas gas producing device causes Acquisition Error too big because of easy entrained air, influence the problem of experimental result, the present invention has reduced Acquisition Error, for open-air shale gas gas collecting and subsequent experimental provide safeguard.
The objective of the invention is to realize in the following manner, a kind of open-air shale gas gas production jar, it is characterized in that, described gas production jar is the cylindric tank body of semi-spherical shape by the top, the gland bonnet that tank base connects, be arranged on tank body one side, one end connect tank body and with tank body in the balancing pipeline that communicates, the gland bonnet of the gas outlet at semi-spherical shape top and gas outlet port constitutes.
The gland bonnet of described tank base connects through the equidistant buckle that arranges, and the button in gland bonnet and the buckle is one, and the card in the buckle and tank body are one, and O-ring seal is set in the gland bonnet.
Described balancing pipeline and tank body axially parallel, the height of balancing pipeline is a little more than the height of gas outlet.
Described tank body adopts PP GRANULES and silica gel resin to make, and is the transparent body.
Described method is that the tank body with the shale sample of packing into submerges in the water of associated vessel, after being full of water in the jar bottom gland bonnet and top gas outlet is sealed with gland bonnet, takes out the tank body after the sealing then from water, carries out desorb at normal temperatures and takes pictures; By the time when assembling a certain amount of gas in the tank body, again tank body is not had in the entry, open the gland bonnet of gas outlet, utilize drainage with the gas collecting of discharging to gas-sample bottle.
The semi-spherical shape at top of the present invention can guarantee the gathering direction of gas, and under the less situation of tolerance, guarantee the collection capacity of gas, the water at the gas extruding semi-spherical shape position that produces, make its osculum through balancing pipeline discharge tank body, the overall process water enriches cavity and sealing can guarantee that air can't sneak into, improve the purity of gas, the setting of balancing pipeline has great importance for the pressure in the sample desorption process and exhaust process.The present invention guarantees that gas assembles at the tank body top, isolate air to be sneaked into and caused Acquisition Error, improved the degree of accuracy result of experiment, the gas production method of gas production jar of the present invention and application gas production jar is simple and practical, the present invention has reduced Acquisition Error, for open-air shale gas gas collecting and subsequent experimental provide guarantee.
Description of drawings
Fig. 1 is master's TV structure synoptic diagram of the present invention;
Fig. 2 is plan structure synoptic diagram of the present invention,
Among the figure, 1 gas outlet, 2 tank bodies, 3 balancing pipelines, 4 osculums, 5 buckles, 6 gland bonnets, 7 gland bonnets.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, 2, gas production jar of the present invention is the tank body 2 of semi-spherical shape by the top, the gland bonnet 6 of tank body 2 bottoms, be arranged on tank body 2 one sides, one end connect tank body 2 and with tank body 2 in the balancing pipeline 3 that communicates, the gland bonnet 7 of the gas outlet 1 at semi-spherical shape top and gas outlet 1 port constitutes.The gland bonnet 6 of tank body 2 bottoms connects through the equidistant buckle that arranges 5, button in gland bonnet 6 and the buckle 5 is one, and the card in the buckle 5 and tank body 2 are one, in the gland bonnet 6 O-ring seal are set, balancing pipeline 3 and tank body 2 axially parallels, the height of balancing pipeline 3 is a little more than the height of gas outlet 1.
The gas production method of utilizing the gas production jar of the present invention, the shale sample packed into not to be had in the entry behind the tank body 2, is full of water and connects bottom gland bonnets 6 by some buckles 5 in tank body 2, and gas outlet 1 top is through gland bonnet 7 sealings, take out the tank body 2 after the sealing then, carry out desorb at normal temperatures and take pictures; By the time when assembling a certain amount of gas in the tank body 2, in the water in the associated vessel that again tank body 2 submerged, open the gland bonnet 7 of gas outlet 1, utilize drainage with the gas collecting of discharging to gas-sample bottle, deliver to the laboratory and detect.
