Abstract

The utility model discloses a metering device in coalbed methane water current discharge and recovery. The metering device in coalbed methane water current discharge and recovery is composed of a water flow meter and a three-state separating device, and the water flow meter is connected with a drainage outlet of the three-state separating device. The three-state separating device is designed to be a water storage pool. The periphery of the water storage pool is respectively provided with a water inlet, an exhaust port, a drainage outlet and a slag tap. An upper sealing piece is placed at the front end of the exhaust port, and controls a switch of the exhaust port through an up-floating ball; a lower sealing piece is placed at the front end of the drainage outlet, and controls a switch of the drainage outlet through a down-floating ball; and a slag tapping valve is placed at the rear end of the slag tap, and controls a switch of the slag tap through the slag tapping valve. The water flow meter is simple in structure, low in requirements, capable of greatly prolonging service life and conducting metering on interrupted liquid and liquid-state fluid with solid, gas and liquid, small in metering error and large in measuring range.

Description

Water flow measurement device during coal bed gas row adopts
Technical field
The utility model relates to a kind ofly adopts the initial stage row, to the technology that displacement carries out the accurate dynamic monitoring, and water flow measurement device during particularly a kind of coal bed gas row adopts.
Background technology
Coal bed gas row adopt in the process, mainly controls liquid level by the water that extracts in the coal bed gas well, and then keep existing desorption pressures, guarantees the exploitation that coal bed gas is lasting, permanent.Adopt in the process row, especially row adopts the initial stage, and displacement is a very important parameter, and therefore accurately the metering displacement is also just very important, is the correct important evidence of formulating the row's of adopting measure and selecting equipment for use.
The displacement of general coal bed gas well and its residing zone have that important related (arranging the product initial stage, osiery northern territory aquifer yield is generally at 50~200 m 3/ d, in northern zone, indivedual straight wells and horizontal well aquifer yield are bigger, and displacement reaches 300m 3/ d adopts in the process normal row, and displacement is sometimes less than 10 m 3/ d.), and be not continuous, and often contain a large amount of ickings and a small amount of gas.Measure with common water meter, ickings is assembled in water meter gradually, often makes water meter malfunctioning, and under the situation that gas-liquid two-phase flows, and common water meter also is difficult to wherein fluid liquid is accurately measured.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, to water flowmeter require low, can improve the application life of water flowmeter greatly, can carry out intermittent current and adopt middle water flow measurement device with the coal bed gas row that the fluid liquid that contains solid and gas measures and error in dipping is little, measurement category is big.
The technical solution of the utility model is:
Water flow measurement device during coal bed gas row adopts is made up of water flowmeter and tri-state separation unit, and it is characterized in that: water flowmeter is connected with the outfall of tri-state separation unit.Tri-state separation unit be used for solid, gas and the moisture of draining from, water flowmeter is used for discharge is carried out accurate measurement.
Described tri-state separation unit is designed to a reservoir, is respectively equipped with water inlet, exhaust opening, outfall and slag tap around the reservoir, and the exhaust opening front end is provided with seal, by the switch of upper floating ball control exhaust opening; The outfall front end is provided with lower seal, by the switch of following ball float control outfall; The slag tap rear end is provided with deslagging valve, controls the switch of slag tap by deslagging valve.
Be provided with upper limit water level and lower limit water level in the described reservoir, upper limit water level is between water inlet and exhaust opening, and the lower limit water level is determined the time of exhaust and draining by water level between water inlet and outfall.
The beneficial effects of the utility model are:
Common water flowmeter front end is provided with tri-state separation unit, solid, gas and water are separated, and then measure discharge, avoid ickings in water flowmeter, to assemble gradually and damage water flowmeter, thereby improved the application life of water flowmeter greatly, saved use cost.Control automatic vent and draining by upper limit water level and lower limit water level, can carry out the fluid liquid metering of intermittent current and error in dipping is little, measurement category is big.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
By reference to the accompanying drawings the utility model is described in detail:
As shown in Figure 1, the utility model is made up of water flowmeter 8 and tri-state separation unit, water flowmeter 8 is connected with the outfall 9 of tri-state separation unit, tri-state separation unit be used for solid, gas and the moisture of draining from, water flowmeter 8 is used for discharge is carried out accurate measurement.This tri-state separation unit is designed to a reservoir 13, and reservoir 13 left upper portion are provided with water inlet 1, top and are provided with that exhaust opening 3, lower right side are provided with outfall 9, the bottom is provided with slag tap 11; Exhaust opening 3 front ends are provided with seal 4, by the switch of upper floating ball 5 control exhaust openings 3; Outfall 9 front ends are provided with lower seal 7, by the switch of following ball float 6 control outfall 9; Slag tap 11 rear ends are provided with deslagging valve 10, control the switch of slag tap 11 by deslagging valve 10.Be provided with upper limit water level 2 and lower limit water level 12 in the reservoir 13, upper limit water level 2 is between water inlet 1 and exhaust opening 3, and lower limit water level 12 is determined the time of exhaust and draining by water level between water inlet 1 and outfall 9.
The course of work of tri-state separation unit is as follows: the water that is mixed with ickings and gas enters into reservoir 13 by air inlet port 1, ickings is because gravity sinks to the bottom of reservoir 13, gas floats to reservoir 13 tops on then and is discharged by exhaust opening 3, solid ickings, gas and moisture from.When the water level in the reservoir 13 was lower than lower limit water level 12, following ball float 6 was because gravity fall is blocked lower seal 7, and outfall 9 is closed and not draining; When water level was higher than lower limit water level 12, following ball float 6 was because buoyancy of water floats, and outfall 9 is opened the beginning draining, does not at this moment have gas and solid in the water of Pai Chuing.When the water level in the reservoir 13 was lower than upper limit water level 2, upper floating ball 5 was because gravity fall is opened seal 4, and exhaust opening 3 is opened, and the gas in the water is partly drained; When water level high position upper limit water level 2, upper floating ball 5 is because buoyancy of water is blocked seal 4, and exhaust opening 3 is closed, and prevents from leaking.
By regularly opening deslagging valve 10 the solid ickings of the bottom of reservoir 13 etc. is discharged by slag tap 11.
