Abstract
The invention is relates to a device for obtaining gas from a rock core. The structure is characterized in that the upper and lower ends of an organic glass tube are provided with external screw threads circumferentially, an upper organic glass cover and a lower organic glass cover are connected with the external screw threads of the organic glass tube through internal screw threads, and sealing rings are arranged between the upper organic glass cover and the organic glass tube and between the lower organic glass cover and the organic glass tube; a hollow screw water outlet is positioned on the upper organic glass cover, a rock core sample of stratum exploration of a drilling machine is placed inside the organic glass tube, and a hollow screw water inlet which is positioned on the lower organic glass cover is connected with ma-liao bottle through a water inlet pipe. The device is capable of collecting gas that is separated from the rock cores in different stratigraphic positions (depths), and has the characteristics of convenient usage and high gas collecting efficiency.
Description
Technical field
The present invention relates to a kind of core collector.
Background technology
As the gas hydrate of a kind of high-quality, cleaning, new forms of energy, reserves tool greatly, is extensively distributed in Frozen Ground Area and region, continental platform, is considered to most important substitute energy of mankind's 21 century, has wide development space and application prospect.In the time of Frozen Ground Area exploration, searching gas hydrate, owing to directly not obtaining gas hydrate in drilling process (under cryogenic high pressure condition, otherwise be decomposed into rock gas and water) device, therefore, generally take drilling core, collect the gas separating, carry out component (being mainly methane gas) and the content of analytical gas, thereby judge whether gas hydrate exist, and the layer position and the reserves etc. that store.
。
Summary of the invention
In view of above-mentioned, object of the present invention aims to provide one and is applicable to field brill drilling core collector.This device can meet in drilling process, separates and collect the gas in the core of Different Strata position (degree of depth), thereby analyzes component (composition) and the content of contained gas in this core.
The object of the present invention is achieved like this:
A kind of core collector, is mainly made up of organic glass cylinder, organic glass upper cover, organic glass lower cover, O-ring seal, negative inspiratory pressure device, hollow nut, silica gel pad, horse Liao Te bottle, water inlet pipe and hollow nut.The upper and lower two ends of organic glass cylinder circumference is male thread, and organic glass upper cover is connected with organic glass cylinder male thread by interior screw thread with organic glass lower cover, and O-ring seal is housed therebetween; On organic glass, be covered with cored screw water delivering orifice, organic glass cylinder is built-in with rig and bores and survey stratum core sample, and the cored screw water inlet covering under organic glass is connected with horse Liao Te bottle by water inlet pipe.
Advantage of the present invention is:
1,, in the wild in the relatively simple situation of test condition, operate this device and can obtain the gas in core.Analyze its component (being mainly methane) and content by the gas obtaining, thereby judge whether gas hydrate exist, and the layer position and the reserves that store.
2, this device can meet and collects the inner core in Different Strata position (degree of depth) isolated gas, has easy to usely, gets the feature that gas efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the hollow nut schematic diagram of Fig. 1.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of core collector, a kind of core collector, is mainly made up of organic glass cylinder 4, organic glass upper cover 2, organic glass lower cover 6, O-ring seal 3, cored screw water delivering orifice 1, cored screw water inlet 7, hollow nut 10, silica gel pad 11, horse Liao Te water bottle 9, water inlet pipe 8.The internal diameter of organic glass cylinder 4 is 8cm, external diameter 10cm, high 12cm, upper and lower two ends circumference is male thread, organic glass upper cover 2 is connected with organic glass cylinder 4 male threads by interior screw thread with organic glass lower cover 6, O-ring seal 3 is housed therebetween, organic glass upper cover 2 is provided with cored screw water delivering orifice 1, organic glass cylinder 4 is built-in with the core sample 5 that bores control with rig, and the cored screw water inlet 7 of organic glass lower cover 6 is connected with horse Liao Te bottle 9 by water inlet pipe 8.Horse Liao Te water bottle 9 is fixed in iron stand clip.
Pass through water inlet pipe 8 by horse Liao Te water bottle 9, from bottom to up, to the device water filling that core is housed to 4 water fillings of organic glass cylinder, in the time that water flows out from water delivering orifice, close water inlet pipe switch, the hollow nut 10(that is filled with silica gel pad 11 that simultaneously screws on is shown in Fig. 2), cored screw water inlet from organic glass lower cover 6 is discharged 30-50ml water, make in device in vacuumizing state, then, close the valve on cored screw water inlet 7, screw on and be filled with the hollow nut 10 of silica gel pad 11 at cored screw water inlet 7.Core sample 5 disintegration under the effect of water that organic glass cylinder 4 is built-in, discharges gas.After gas is separated, again syringe needle is passed and has silica gel pad 11, be inserted into hollow nut 10 to organic glass cylinder 4 vacuum positions, extract the separated gas of core sample 5, thereby analyze component (composition) and the content of contained gas in this core, and the corresponding position of stratum of core (degree of depth).According to the component of gas (being mainly methane gas) and content, thus analyze and judge whether this stratum or region exist gas hydrate, with and reserves number.
Embodiment 2
Cored screw water inlet 7 is loaded onto negative inspiratory pressure device.It is macromolecule organic material that there are stainless steel spring, outer cover in negative inspiratory pressure device inside.First it is vacuumized, make spring-compressed arrive the limit, close the valve on cored screw water inlet 7, ensure in its device that vacuum is without air.The gas that core disintegration separates just automatically enters in negative inspiratory pressure device.Syringe needle is connected with negative inspiratory pressure device, extracts the separated gas of core sample and analyze.
