Abstract
The invention relates to the technical field of oil field water well operation, and belongs to an anti-freezing process for a blowout prevention pipe and a cable for testing an oil field water injection well. The anti-freezing device is designed for solving the problems that the cable is easy to freeze and the anti-freezing and anti-blocking pipes are easy to freeze and block during testing construction in winter of the oil field water injection well. The invention mainly comprises a blowout prevention pipe 1, an integrated coil 2, a cable 3, a multi-core wire 4, a heating power supply 5, a generator 6, a cable deicing device 7 and a cable vehicle 8, and the blowout prevention pipe 1 and the cable 3 are matched with the water injection well test for antifreezing and unfreezing processes. The invention is used in the operation of oil field and water well, and has the advantages of low cost, high efficiency and fast cable deicing, anti-freezing and unfreezing of the blowout prevention pipe, and the like.
Description
Technical field:
The present invention relates to oil-field brine well operations technical field, belong to a kind of water injection well in oil fields test lubricator and the antifreeze technology of cable.
Background technology:
At present, water injection well in oil fields is tested when constructing in the winter time, the easy icing problem of freezing with lubricator, blocking up of cable that takes place, and the way to the lubricator draining overflow is mainly taked at the scene.Adopt this method, find through after the application of long period, have the problem of the following aspects: at first be that draining overflow is big to ambient influnence, contaminated environment is unfavorable for environmental protection easily; Secondly, influence execute-in-place workman's test construction safety.Because in when construction test in winter, the overflow that lubricator is emitted congeals into ice rapidly easily, to the test workman climb lubricator and in the well site operation all very unfavorable, very easily slide into or weigh down and fall, have bigger potential safety hazard; Once more, the large and small difficult control of draining overflow, it is excessive that overflow is put, and causes waste, too small if overflow is put, do not have antifreeze, stifled effect again, and lubricator freezes, blocks up phenomenon easily.
Summary of the invention:
For solve water injection well in oil fields test in the winter time when construction be prone to take place cable freeze freeze with lubricator, stifled problem; The present invention provides a kind of can either realize low cost, safety, quick cable deicing efficiently, can make the supporting antifreeze technology with lubricator and cable of lubricator injection well testing antifreeze, that thaw again.
The present invention is through realizing with lower device: lubricator, integrated coil, cable, multiple core cord, heating power supply, generator, cable ice remover and cable car are formed; Wherein integrated coil is centered around around the lubricator; Integrated coil links to each other through multiple core cord with the output of heating power supply; The input of heating power supply is connected with generator, and the cable ice remover is fixed on the position of folding and unfolding cable in the cable car; The present invention realizes through following steps:
A, after at first heating power supply direct current that generator is provided is converted into high frequency electric; Offer integrated coil; Integrated coil and lubricator form electromagnetic induction effect; The high frequency electric that heating power supply is provided is converted into the electromagnetic field of high frequency; Make lubricator upwards produce high-frequency vortex on every side through integrated coil; To the lubricator heating, lubricator is thawed;
B, the folding and unfolding of cable car control cables then, the cable ice remover is held on the cable, and cable its floating ice in traveling process is removed by the cable ice remover;
C, last, cable de-icing device carries out the hot blast heating again to the cable after handling, and removes the ice quarrel on the cable.
Compared with the prior art the present invention has following advantage:
1), the cable ice remover is simple in structure, with low cost, quality is light, can be reached for disappear the fast effect of ice of cable;
2), this process implementing is convenient, guaranteed the safety of operation, and is and good to the defrost result of lubricator.
Description of drawings:
Fig. 1 is a The field sketch map of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done further auspicious stating: the present invention is through realizing with lower device: lubricator 1, integrated coil 2, cable 3, multiple core cord 4, heating power supply 5, generator 6, cable ice remover 7 and cable car 8 are formed; Wherein integrated coil 2 is centered around around the lubricator 1; Integrated coil 2 links to each other through multiple core cord 4 with the output of heating power supply 5; The input of heating power supply 5 is connected with generator 6, and cable ice remover 7 is fixed on the position of folding and unfolding cable 3 in the cable car 8; The present invention realizes through following steps:
A, after at first heating power supply 5 direct current that generator 6 is provided is converted into high frequency electric; Offer integrated coil 2; Integrated coil 2 forms electromagnetic induction effect with lubricator 1; The high frequency electric that heating power supply 5 is provided is converted into the electromagnetic field of high frequency; Make lubricator 1 upwards produce high-frequency vortex on every side through integrated coil 2; To lubricator 1 heating, lubricator 1 is thawed;
B, the folding and unfolding of cable car 8 control cables 3 then, cable ice remover 7 is held on the cable 3, and cable 3 its floating ice in traveling process is removed by cable ice remover 7;
C, last, the cable 3 after 7 pairs of processing of cable de-icing device carry out the hot blast heating again, remove the ice quarrel on the cable 3.
