Description
Technical field
The present invention relates to a kind of petroleum machinery, particularly relate to a kind of sleeve pipe overflow monitoring device.
Background technology
Underground work is the important means implementing petroleum natural gas exploration, due to the importance of safety and environmental protection work, requires more and more higher to underground work well control.Should safety, high-quality, implement underground work efficiently, be conducive to protecting petroleum resources again, improve recovery ratio, extend oil, the life-span of gas well, prevent blowout and the generation of blowout out of control accident.Different with controlling oil-air pressure complexity according to control mode, well control work is divided into one-level well control, two grades of well controls, three grades of well controls." base oneself upon one-level well control, carry out two grades of well controls, stop three grades of well controls " should be accomplished in order to ensure to be perfectly safe.Therefore carry out one-level well control to be particularly important.At present, one-level well control is that the head of liquid using suitable well killing fluid density to be formed carrys out equilibrium strata pressure, prevents the well control technique that overflow is formed.Main is first kill-job before acting inner tube post of going into the well, and irrigates, in well, the liquid-column height that well liquid reduces because tripping out tubing string with holding during playing lower tubular column.Oil field development is gradually reduced to regular period, strata pressure, until less than pressure and hydrostatic pressure, deficit occur in many oil field stratums, leakage is serious, and in well, the liquid level distance well head degree of depth is more than 1000 meters.In order to prevent overflow from occurring during Downhole Construction, in well, liquid level is in any degree of depth and all takes liquid filling mode to keep liquid-column height, the way of this blindness not only to waste a large amount of manpower and materials, also result in formation contaminant, be unfavorable for oil layer protection.
Summary of the invention
The technical problem to be solved is: provides a kind of and can stop the sleeve pipe overflow monitoring device that gas blowout accident occurs.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: sleeve pipe overflow monitoring device, including: sleeve pipe, the some oil pipes being arranged in sleeve pipe, connected by box cupling between described some oil pipes, annular space and liquid level it is provided with in described sleeve pipe, it is provided with the air gun being connected with described annular space near the position of import at described sleeve upper end, described air gun passes through trachea and source of the gas, described air gun is connected with controlling device by two holding wires, central authorities' control and display module it is provided with in described control centre, acoustic emission and acquisition module and signal transmit and data transmission module.
The invention have the advantage that above-mentioned sleeve pipe overflow monitoring device; in petroleum and natural gas well overhaul, light maintenance job execution, the real-time of sleeve pipe liquid level is monitored; it it is the active technique equipment carrying out one-level well control; gas blowout accident can be stopped occur; for the low pressure well that air content is little; fluid level data and variation tendency in well can be grasped at any time; the most just need not irrigate well killing fluid in well; this had both greatly reduced the equipment conveying cost and the cost of transportation of well killing fluid increased because of liquid filling, protects again oil reservoir and is not contaminated.For high-pressure well, it is possible to grasp fluid level data and variation tendency in well at any time, before overflow occurs, without the measure waiting overflow to take closing well after occurring again, well control safety can be considerably increased by closing well.

Detailed description of the invention
The particular content of the present invention is described in detail below in conjunction with the accompanying drawings with specific embodiment.
As shown in Figure 1, sleeve pipe overflow monitoring device, including: sleeve pipe 1, the some oil pipes 2 being arranged in sleeve pipe 1, connected by box cupling 3 between described some oil pipes 2, annular space 4 and liquid level 5 it is provided with in described sleeve pipe 1, the air gun 6 being connected with described annular space 4 it is provided with near the position of import in described sleeve pipe 1 upper end, described air gun 6 is by trachea 7 and source of the gas 8, described air gun 6 is connected with controlling device 10 by two holding wires 9, central authorities' control and display module it is provided with in described control centre 10, acoustic emission and acquisition module and signal transmit and data transmission module.
Above-mentioned sleeve pipe overflow monitoring device is the equipment of liquid level in a kind of real-time monitoring sleeve, keep communicating with control device 10 in real time, once receive instruction or arrive timing, acoustic emission module i.e. starts air gun 6 by the parameter set and sends sound wave to down-hole, sound collecting module is started working and the result gathered is stored simultaneously, measure complete, enabling signal transmission and data transmission module, the data collected together with casing pressure, wellhead temperature and equipment self relevant parameter are sent along to central authorities' control and display module, central authorities control and display module stores after receiving the data of collection, Treatment Analysis, finally obtain oil well liquid level data.
Specific works process includes following step:
One, under controlling device 10 effect, electric control pulse sound source sends sound wave to down-hole, i.e. source of the gas 8 passes through trachea 7 to air gun 6 inner inflatable, after air pressure reaches certain pressure, acoustic emission module opens air gun 6 inner valve, and the gas in gun body 6 discharges suddenly, produces a shock wave.Complete the transmitting of air gun 6.
Two, while sending sound wave, the collection of sound collecting module commencing signal.
Three, after signals collecting completes, signal is processed by signal transmission and data transmission module, and processing procedure includes a series of processes such as signal filtering, the extraction of box cupling ripple, on-the-spot velocity of sound resolving, Liquid Surface Behavior extraction, level calculating.
Four, the data collected are controlled and display module to central authorities together with self relevant parameter of casing pressure, wellhead temperature and equipment is sent along, central authorities control and display module carries out storing after receiving the data of collection, Treatment Analysis, finally obtain oil well liquid level data.
Main performance:
(1) test: survey a fluid value in every 10 seconds
(2) display performance:
The initial level degree of depth (surveyed liquid level of starting shooting when rountrip starts)；
Construction midway level in real time；
A display per minute level change rate (i.e. climbing, rate of descent.Level is reduced to rise, and increases to decline), unit is m/s；
(3) overflow trend is reported to the police: when level value and liquid level climbing meet following condition, monitor is reported to the police.Alarm form is: alarm lamp flicker, alarm hooter ring, voice are reported (when forecast overflow occurs repeatedly
Between, the lower step of prompting puts operation into), until risk releases.
The initial level degree of depth is when 0-100m, if liquid level climbing is less than 0.5m/s more than or equal to 0.5m or climbing but liquid level rises 20m；
