Abstract
The utility model relates to a silenced bomb well head tester to solve the safety problems existing in the prior art. The adopted technical scheme is that the tester comprises an air gun and a main engine, wherein the air gun comprises an air gun main body, an air-release valve, a microphone and a control handle; the microphone is connected with the main engine through a cable; the air gun main body is connected with the air-release valve, the microphone and the control handle; the air gun main body is as follows: the front end in a shell is provided with a hollow central spindle, a valve body is arranged at the rear end of the shell, and a valve cover is connected with the shell and the valve body; a valve rod is installed in the shell, one end of the valve rod extends out of the valve body, and the other end of the valve rod penetrates through the valve body and the valve cover and is connected with the control handle; a sealing ring is arranged in a groove on the valve rod in the valve body; a spring is arranged on the valve rod in the valve body; and an air inlet/outlet end of the valve rod has a hollow structure along the axial direction. The silenced bomb well head tester is safe and reasonable, convenient in operation and easy to maintain, the liquid level can be tested with pressure or without pressure underground, and a silenced bomb can completely replace an acoustic bomb for testing, so that the testing cost is lowered, and the testing safety can be improved.
Description
Technical field
The utility model relates to a kind of measuring apparatus of measuring level in the oil well, particularly a kind of measurement mechanism that does not adopt bullet can measure level in the oil well.
Background technology
At present
,The oil field is extensive use of echometer to the measurement of oil-well level.It is that utilization sound bullet produces the explosion sound wave, transmits sound waves in the down-hole casing, receives the echo of liquid level reflection again, and a series of processing through main frame draw level.The sound bullet belongs to explosive dangerous material, has safety problem, is subjected to public security department's control especially, on transportation, storage, use link strict regulation is arranged.Simultaneously after the gunpowder explosion, gas has corrosivity, and operating personnel are brought potential safety hazard, shortens well head and connects metalwork application life.The sound bullet brings great inconvenience to test job.
Summary of the invention
In order to solve the problem of prior art at secure context, the utility model provide a kind of have safe and reliable, easy to operate, the noiseless bullet well head of advantages such as easy care tester.
The purpose of this utility model is achieved by the following technical solution: noiseless bullet well head tester, constitute by air gun and main frame, described air gun is made up of air gun main body, vent valve, microphone and joystick, microphone is connected with main frame by cable, and the air gun main body is connected with vent valve, microphone and joystick.
Described air gun main body comprises housing, hollow core shaft, valve rod, valve body, valve gap, sealing ring and spring; The housing Inner Front End is installed hollow core shaft, and valve body is installed in the rear end, and valve gap is connected with valve body with housing; Valve rod is packed in the housing, and an end stretches out valve body, and the other end passes valve body and is connected with joystick with valve gap, and sealing ring is packed into and is located in the groove on the valve body inner valve stem, and spring is contained on the valve rod in the valve body.
Above-mentioned noiseless bullet well head tester, the valve rod air inlet and outlet end is a hollow-core construction along axis direction.
Above-mentioned noiseless bullet well head tester for the ease of being connected with oil well casing, is made the external screw thread that is connected with well head at air gun main body end.
The beneficial effects of the utility model are: the utility model air gun designs simplification, in light weight, easy to carry, safety; The main frame volume is little, function is strong, is not subjected to external interference.Pressure is arranged in the down-hole or do not have that depress all can be to liquid level test, and need not use sound bullet, substitute the problem of sound bullet test fully, reduce testing cost, improve test safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, noiseless bullet well head tester is made of air gun and main frame (5).
Described air gun is made up of air gun main body (1), vent valve (2), microphone (3) and joystick (4), microphone (3) is connected with main frame (5) by cable, and air gun main body (1) is connected with vent valve (2), microphone (3) and joystick (4).
Described air gun main body (1) comprises housing (1-1), hollow core shaft (1-2), valve rod (1-3), valve body (1-4), valve gap (1-5), sealing ring (1-6) and spring (1-7); Housing (1-1) Inner Front End is installed hollow core shaft (1-2), and valve body (1-4) is installed in the rear end, and valve gap (1-5) is connected with valve body (1-4) with housing (1-1); Valve rod (1-3) is packed in the housing (1-1), one end stretches out valve body (1-3), the other end passes valve body (1-4) and is connected with joystick (4) with valve gap (1-5), valve rod (1-3) moves in valve body (1-4), sealing ring (1-6) is packed into and is located in the groove on valve body (1-3) inner valve stem (1-2), and spring (1-7) is contained on the valve rod (1-2) in the valve body (1-3).
Valve rod (1-2) air inlet and outlet end is a hollow-core construction along axis direction.
For the ease of being connected with oil well casing, air gun main body (1) end is made the external screw thread that is connected with well head.
Operating principle of the present utility model is: during test, the external screw thread by air gun main body end is installed in air gun on the oil well casing, is connected with main frame by the microphone of cable with air gun.Hollow core shaft plays the gas channeling effect.When in the well casing pressure being arranged, press joystick, gas enters in the air gun by the hollow-core construction of hollow core shaft and valve rod in the well, produces ping, and microphone changes into the signal of telecommunication with the ping of receiving, is delivered to main frame, records level.When not having casing pressure in the well, air gun connects nitrogen cylinder, presses joystick, and nitrogen is sent by air gun, through the oil well liquid level reflection, equally through hollow core shaft, the hollow-core construction of valve rod enters in the air gun, microphone changes into the signal of telecommunication with the ping of receiving, is delivered to main frame, records level.
