Abstract
The utility model provides a mass flowmeter used at the well head of a coalbed gas well, relating to a coalbed gas well dynamic monitor technology. The utility model is characterized in that a baffle is installed in a liquid inlet tube; the liquid inlet tube is connected with a buffer tube installed in a casing; a magnet is installed on the lateral side of a tipper; and a counter is installed in the casing. The beneficial effect of the utility model is that the mass flowmeter can prevent the disconnected current of the liquid from striking with relative great force, so that the liquid entered the measuring tipper is relatively slow which is favorable to correct measurement. The length of the buffer tube is about equal to the length of the tipper. A lot of small holes are arranged on the buffer tube, making the liquid flow into the tipper evenly which is also favorable to correct measurement. The magnet is installed on the tipper and the counter is installed in the casing, so automatic measurement can be realized. The device has simple structure, low price and small measurement error.
Description
Technical field
The utility model relates to a kind of coal bed gas well Dynamic Monitoring.
Background technology
During exploiting coal bed methane, important row of the liquid outlet quantity of gas well adopts parameter, is that the important evidence of adopting measure and selecting equipment for use is arranged in correct formulation.General coal bed gas well liquid outlet quantity is lower, and is not continuous, and often contains 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 indicator of water gauge stuck malfunctioning, and under the complex situations of biphase gas and liquid flow, and common water meter also is difficult to wherein liquid phase fluid is accurately measured.The tipping bucket type flow meter that is used for crude oil measurement on oil well only is applicable to that oilwell produced fluid amount stablizes, contains the liquid flow mearuement of less solid impurity, and this flow meter cost of manufacture is higher.The liquid flowmeter amount that the flow meter of other form also is not suitable for measuring this intermittent current and contains gas.
The utility model content
The purpose of this utility model provides low, the measurable coal bed gas well well head mass flowmenter that contains gas and granule foreign of a kind of cost, is applicable to that flow is low, liquid flows unsettled liquid flow mearuement.
Specific embodiments of the present utility model is to realize like this, a kind of coal bed gas well well head mass flowmenter, constitute by shell and installation tipping bucket in the enclosure, counter is housed on shell, magnet piece is housed on tipping bucket, on shell, have feed tube and drain pipe, its special character is, baffle plate is housed in feed tube, and feed tube is connected with the separator tube of installing in the enclosure, is evenly equipped with aperture on the separator tube.
The beneficial effects of the utility model are because baffle plate is housed in feed tube, can prevent liquid between the greater impact that stops, make the flowing fluid ratio that enters in the metering tipping bucket milder, help accurate measurement.Because feed tube is connected with separator tube, the about and tipping bucket equal in length of the length of separator tube, and many apertures are arranged on separator tube, and liquid is flowed in the tipping bucket equably, also help accurate measurement.Because magnet piece is housed on tipping bucket, counter is installed in the enclosure, can realize automatic gauge.This apparatus structure is simple, and is cheap, and error in dipping is little, be suitable at the coal bed gas well well head interruption flow liquid body flow, contain the liquid flow mearuement of solid particle and gas.
Description of drawings
Accompanying drawing is a cross-sectional view of the present utility model.
The specific embodiment
Process diameter and be 3 millimeters aperture on separator tube 3,2 millimeters of aperture pitch are evenly distributed on separator tube 3 downsides, and the length of separator tube 3 and the length of tipping bucket are about equally.Separator tube 3 is welded on the place, inlet opening on the left plate of shell, the two ends of tipping bucket 4 are installed on the support in the shell 8 by rotating shaft, a magnet piece 5 is installed at the right flank of tipping bucket 4.Plate washer 1 is welded on top in the water inlet pipe 2, generally should be greater than the radius of water inlet pipe, water inlet pipe 2 left ends are welded with flange, and the water inlet pipe right-hand member is welded on place, shell 8 inlet openings.Counter 6 is installed on the right plate of shell 8, counter can be selected various forms of counters such as Wei root sensor or tongue tube counter for use.Outlet pipe 7 is installed in shell 8 delivery port places, and the outlet pipe lower end is welded with flange.
This flow meter is installed on the well head of gasser by suction flange and outlet(discharge) flange, when the water of gasser outflow enters water inlet pipe, stopped by plate washer 1, its flow velocity is slowed down, can enter more lentamente in the separator tube 3,, make water from aperture, flow in the tipping bucket 4 equably because of the bottom of separator tube 3 is evenly equipped with aperture, further alleviated impact, can make the water yield of metering more accurate the water in the tipping bucket.
