Description
Technical field:
The utility model relates to multi-functional oil well sampler, and the sampling and the exploitation dynamic fluid character that are particularly useful for high gas-oil ratio (HGOR) or little sulfide hydrogen oil well are monitored desired oil gas water complete analysis sampling.
Background technology:
At present, production tree sample cock mounting means generally has two kinds, and a kind of is that sample cock is downward, and a kind of is that sample cock is in level, and sample tap all is one section short tube vertically downward.What oil well drew oil sample general use is uncovered iron sample bucket, a hand is opened sample cock in sampling process, portable a sample bucket, and make sample bucket keep tilting, in order to avoid oil sample spills, also want eyes seeing the amount whether oil of sample bucket the inside meets the demands simultaneously.Mainly have following problem when drawing oil sample: 1, the workman will be with portable sample bucket, and inconvenient operation exists gas and impacts the risk that oil in the sample bucket spills oil to come, splash on the clothes or the production tree platform on; 2, high gas-oil ratio (HGOR) well, sample time is long, and labor strength is big; If 3 temperature are too high, also scald the workman easily.If 4 oil well sulfide hydrogens will endanger workers'health, even cause hydrogen sulfide poisoning.
At present, getting the casinghead gas sample generally is to get in the gas outlet that metering separator is arranged, and there are the following problems to get gas: 1, will between the valve group this well be imported measurement flow from production procedure, could take a sample in metering separator, workload is big; 2, the metering separator that has is in multi-purpose station, and the risk of then getting the gas sample is bigger.
In addition, outside the production tree sample tap is exposed at present, the general measure that when sample cock fits badly, does not prevent the crude oil water clock, crude oil easily drains on the production tree platform from sample cock.What have has taked in the way of sample tap outlet with iron wire extension mineral water bottle, and there are the following problems for this way: 1, each sampling all will be taken off mineral water bottle, has got sample and has hung up again, and iron wire is disconnected easily; 2, mineral water bottle is exposed in the open, and is aging easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of multi-functional oil well sampler, it can effectively solve the not tight problem of sample valve closing that takes, can reach and reduce sampling working strength of workers and risk, when sample cock is not closed completely, prevent the measure of crude oil water clock to the production tree platform.
The technical scheme that the utility model sampler is adopted is: comprise feed tube, the cavity top cover, horn mouth, shock plate, the shock plate supporting leg, last discharging tube, draining valve, following discharging tube, the shock plate sump pit, sample bucket hook, well floor, the sampler cavity, stack, place on the top cover on sampler cavity top and connect stack and feed tube respectively, the feed tube lower end connects horn mouth, the sampler inside cavity connects shock plate, four supporting legs of shock plate are welded on the inwall of sampler cavity, between shock plate and sampler cavity, be provided with the shock plate sump pit, sampler cavity lower end is connected with well floor, connect under the well floor and go up discharging tube, last discharging tube is by the screwed connection draining valve, the lower end of draining valve is connected with down discharging tube, is connected with the sample bucket hook on the following discharging tube.
The sampler cavity is columned cavity.
Stack is settled against feed tube, and the center of feed tube overlaps with sampler cavity center.
Bell-mouthed bottom surface circular diameter is less than the internal diameter of sampler cavity, and with the outside snap of stack.
Feed tube and stack all are provided with screw thread.
Feed tube or be straight tube perhaps is the bend pipes of 90 degree.
Shock plate is tapered, and its bottom surface is circular the same big with horn mouth bottom surface circle.
Well floor has tapering.
There is angle following discharging tube top and bottom.
Of the present utility modelly be a little: it can effectively solve and take the not tight problem of sample valve closing, can reach to reduce sampling working strength of workers and risk, prevents the measure of crude oil water clock to the production tree platform when sample cock is not closed completely.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, comprise feed tube 1, cavity top cover 2, horn mouth 3, shock plate 4, shock plate supporting leg 5, last discharging tube 6, draining valve 7, following discharging tube 8, shock plate sump pit 9, sample bucket hook 10, well floor 11, sampler cavity 12, discharging tube 13, place on the top cover 2 on sampler cavity 12 tops and connect stack 13 and feed tube 1 respectively, feed tube 1 lower end connects horn mouth 3, the sampler cavity 12 inner shock plates 4 that connect, four supporting legs 5 of shock plate 4 are welded on the inwall of sampler cavity 12, between shock plate 4 and sampler cavity 12, be provided with shock plate sump pit 9, sampler cavity 12 lower ends are connected with well floor 11, well floor connects upward discharging tube 6 for 11 times, last discharging tube 6 is by screwed connection draining valve 7, the lower end of draining valve 7 is connected with down discharging tube 8, is connected with sample bucket hook 10 on the following discharging tube 8.
Discharging tube 13 is settled against feed tube 1, and the center of feed tube 1 overlaps with sampler cavity 12 centers.
The bottom surface circular diameter of horn mouth 3 is less than the internal diameter of sampler cavity 12, and with the outside snap of discharging tube 13.
Well floor 11 has tapering.
There is angle following discharging tube 8 top and bottom.
According to the production tree sample cock is parallel to the ground or vertical, and to select feed tube 1 respectively for use be straight tube or be 90 degree bend pipes, and feed tube 1 is connected with sample cock on the production tree flowline by the silk mouth and draws oil sample.
Sample bucket is hung over the sample bucket link up with 10 places,, can not cause the hydraulic shock liquid level to cause liquid splash in the sample bucket because down the top and bottom of discharging tube 8 make that discharging tube 8 can lean against on the sample bucket wall down at an angle.Open draining valve 7, at the sample cock of opening on the production tree flowline, fluid enters sampler cavity 12 by inlet 1, effect by shock plate 4, liquids and gases are separated, gas passes through to discharge by stack 13 behind the space between horn mouth 3 and the sampler cavity 12, liquid is because the effect of blocking of horn mouth 3, can not enter into stack 13, can only be descending at action of gravity lower edge shock plate 4, enter into the bottom of sampler cavity 12 by shock plate sump pit 9, by last discharging tube 6, draining valve 7, discharging tube 8 enters into sample bucket down.
(1) gets the gas sample
(2) prevent that production tree sampling gate from fitting badly water clock
Sampler keeps connection status by feed tube 1 and production tree sample cock always, draining valve 7 is in closed condition at ordinary times, when production tree sampling gate fits badly water clock, liquid remains in the sampler cavity 12, can not discharge, because the uncovered all the time exhaust at any time of stack 13 can not cause sampler to build the pressure.
