Abstract
The utility model discloses an automatic air gun for an echo monitor of an oil well, which is mainly composed of an outer explosion device, an inner explosion device and a gun tube. The conversion of the operating process of outer explosion and inner explosion can be automatically finished according to the pressure change of an annular space of an oil well under the control of a computer. The utility model has the advantages of easy use and reliable operation and provides an ideal automatic monitoring instrument for the development of oil fields.
Description
The utility model relates to a kind of improved Automatic air gun that is used for oil well echo monitor in oilfield development process, particularly a kind of be applicable to must not roll over to debug whole can finish the outer quick-fried or implosion and the Automatic air gun of conversion mutually thereof automatically.
In oil extraction process, extensively adopt echo monitor monitoring oil-well level,, grasp the oil well pressure state, determine oil well output, permeability, parameters such as pump setting depth so that calculate bottom pressure.The ping that oil well echo monitor utilizes its air gun to produce is propagated downwards along the oil well oil casing annular space, the reflected impulse that produces when running into oil well liquid level and other obstruction changes electric pulse into by the loudspeaker reception and imports computer into, by record after the Computer Processing.The pressure and other parameters of the propagation time of ping, oil well casing annular space under the simultaneous computer respective record, thus reach the purpose of oil well monitor.
The source of the gas that the air gun of oil well echo monitor produces ping has two kinds: (1) is that the gas cylinder that carries is an external air source; (2) be that the interior air pressure of oil well oil conduit annular space is inner source of the gas, thereby produce two kinds of modes of operation: (1) is when external air source pressure＞inner bleed pressure, air gun utilizes external air source to produce ping, and this is called the outer quick-fried formula course of work, is called for short outer quick-fried; (2) when external air source pressure＜inner bleed pressure, utilize inner source of the gas to produce ping, this is called the implosive course of work, is called for short implosion.
The air gun of existing oil well echo monitor is made up of electromagnetic valve, air valve and gun barrel.During work, externally bleed pressure is greater than producing outer quick-fried (or implosion) in (or less than) inner bleed pressure scope automatically.If inner bleed pressure during greater than (or less than) external air source pressure limit, then can not produce ping because of variation.Promptly can not carry out automatically continuing monitoring after implosion and the outer quick-fried conversion according to the variation of inner bleed pressure.If want it to carry out implosion and outer quick-fried conversion, then need manually-operated to adjust air gun.Bring difficulty for like this oil well automatic monitoring, increased labour intensity.Air gun as the automatic echo sounding sound of the Texas, USA of introducing in documents machine, during the monitoring oil well, when inner bleed pressure when becoming inner bleed pressure greater than external air source pressure less than external air source pressure, realize outer quick-fried and conversion implosion then to require its high pressure entry side of air valve reversal connection and gun barrel are joined and outlet side and air-pressure chamber or atmosphere link, vice versa.
The purpose of this utility model is that a kind of improved Automatic air gun will be provided, and can calculate machine automatic control carrying out implosion and outer quick-fried mutual conversion by machine according to the situation of change of its inside bleed pressure in the work, does not need manually-operated, has improved the oil well monitor automation.
The new task of this practicality realizes by following technical proposal: the utility model is to increase an implosion device on the basis of existing air gun, and it mainly is made up of right electromagnetic valve, right valve seat, air valve seat.Simultaneously in order to realize effective control of the implosion course of work and the outer quick-fried course of work, an end design and installation of air-pressure chamber housing thereon one way valve.The utility model is reasonable in design, and part increases few, and is with low cost.
Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a concrete structure generalized section of the present utility model.
Fig. 2 is the scheme of installation of the utility model on-the-spot test.
Accompanying drawing number of the present utility model is:
One way valve 1, last air-pressure chamber 2, pressure sensor 3, loudspeaker 4, gun barrel 5, following air pressure, chamber 6, right spool 7, air valve 8, right valve seat 9, right enclosed magnet core 10, right electromagnetic valve 11, left electromagnetic valve 12, left enclosed magnet core 13, left valve seat 14, three-way air valve 15, left spool 16, computer 17, external air source 18, outer quick-fried device 19, implosion device 20, inner bleed pressure 21, external air source pressure 22, oil well 23, last air-pressure chamber housing 24, pipeline 25, lead 26.
Referring to Fig. 1, Fig. 2, the utility model is formed by connecting by outer quick-fried device 19, implosion device 20, gun barrel 5, pressure sensor 3, last air-pressure chamber housing 24, one way valve 1, loudspeaker 4, computer 17, external air source 18, pipeline 25, lead 26 assemblings.Implosion device 20, gun barrel 5 are connected with the three-way air valve 15 of outer quick-fried device 19, and the connection place of three parts forms down air-pressure chamber 6.
Outer quick-fried device 19 is made up of left electromagnetic valve 12, left valve seat 14, three-way air valve 15; Implosion device 20 is made up of right electromagnetic valve 11, right valve seat 9, air valve 8.One way valve 1 one ends are connected with last air-pressure chamber 2, and the other end links to each other with external air source 18 with pipeline 25.
Right electromagnetic valve 11, left electromagnetic valve 12, pressure sensor 3, loudspeaker 4 usefulness leads 26 link with computer 17.
During use, the utility model is installed on the oil well 23, in monitoring, when inner bleed pressure 21＜external air source pressure 22, the gases at high pressure of external air source 18 flow into goes up air-pressure chamber 2, and about in the of 16 the space to be full of left spool.Simultaneously, it is outer quick-fried that the inside bleed pressure 21 that computer 17 is imported according to pressure sensor 3 instructs outer quick-fried device 19 to carry out less than the information of external air source pressure 22: left enclosed magnet core 13 starts, the gases at high pressure of spool 16 tops, a left side are discharged into the atmosphere by left valve seat 14, spool 16 top air pressure in a left side reduce, spool 16 high pressure gas effect thereunder in a left side is opened rapidly down, three-way air valve 15 is opened, and the gases at high pressure of last air-pressure chamber 2 expand, and promptly produce a ping.After ping was finished, left enclosed magnet core 13 successively resetted with left spool 16, thereby finishes once outer quick-fried process.In the quick-fried outside process, implosion device 20 is in closed condition all the time.
When inner bleed pressure 21＞external air source pressure 22, inner source of the gas gases at high pressure are full of right spool, and about in the of 7 the space, in like manner implosion device 20 starts the generation implosion process: right enclosed magnet core 10 starts, right spool 7 is opened, air valve 8 is opened, the gases at high pressure of following air-pressure chamber 6 expand, and promptly produce a ping.Right enclosed magnet core 10 successively resets with right spool 7, thereby finishes implosion process one time.In implosion process, left side enclosed magnet core 13 is in closed condition all the time, inner source of the gas gases at high pressure possibility jack-up left side spool 16, and enter air-pressure chamber 2, but because of the utility model design and installation one way valve 1, inner source of the gas gases at high pressure can not flow into external air source, have guaranteed effectively carrying out of implosion.
