Abstract

The utility model discloses an ultra-deep well down-hole video imaging device which comprises a shell body and a control portion arranged inside the shell body. The control portion is further respectively connected with an imaging portion and a storage portion. The control portion is connected with a power supply portion through a connecting cable. The power supply portion is connected with an above-well device through a steel wire rope cable. According to the ultra-deep well down-hole video imaging device, due to the outer shell which is formed by the matching of a high-integrated design circuit and a mini-type imaging unit, an electromechanical and light integration mini-type high-definition imaging device which can bear the high temperature and the high pressure clearly reflects all states of the lower hole wall of an oil well onto a monitor on the ground, the situations such as fractures, malposition, down-hole junks, filtering pipe hole pipe blocking and quicksand positions of the well wall of the oil well are detected, leakage and damage of a casing pipe or an oil pipe are detected, scale formation or microorganism deposition is detected, when the ultra-deep well down-hole video imaging device is used for drilling detection, the connection situation of a casing coupling can be observed, and a malposition region of a stratum, corrosion and breakage conditions of the casing pipe and the junk blocking situation can be observed.

Description

Ultradeep well downhole video imaging device
Technical field
The utility model relates to the oil well checkout equipment, is specifically related to ultradeep well downhole video imaging device.
Background technology
In prior art, detection and maintenance for oil well, often need to use supersonic imaging device carry out imaging to the down-hole situation, and traditional supersonic imaging device is general test to the situation of down-hole, there is no the directly perceived, accurately of video direct imaging technology at all.While running into down-hole situation complexity, the more difficult imaging of super dark ripple imaging device.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of ultradeep well downhole video imaging device.
The technical solution of the utility model is: ultradeep well downhole video imaging device, comprise housing, and be arranged on the control section in housing, described control section also is connected with respectively imaging moiety and storage area, described control section is connected with power pack by stube cable, and described power pack is connected with uphole equipment by the wire rope cable.
Further improvement of the utility model comprises:
Also be equipped with and increase the weight of part on described housing.
Described housing is that titanium alloy material makes.
Described uphole equipment is logging truck.
The shell that the utility model forms by the supporting miniature imaging of high Integrated design circuit unit can bear HTHP electromechanics---light all-in-one micro high definition imaging device is reflected to the various states of hole wall under oil well on the monitor on ground with analysing clearly, detect the situations such as crack, dislocation, trouble of lost tool in hole, drainage pore blockage and quicksand position of oil-well wall; Survey leakage and the damage of sleeve pipe or oil pipe; Survey knot watchtower in ancient times or microbe deposition.When being used as the boring detection, can observe the connection of casing coupling, the stopping state of the dislocation band on stratum, the corrosion of sleeve pipe and break situation and foreign material; Survey the output position of fluid and particulate, state etc.; Thereby provide reliable basis to the various situations of analyzing oil well.The utility model is simple in structure, reasonable in design, is the special structure form that well workover needs and different gas well well workovers need to design in conjunction with different downhole conditions according to the general super dark oil well of reality.
The accompanying drawing explanation
Fig. 1 is the utility model the first half structural representation.
Fig. 2 is the utility model the latter half structural representation.
In figure: 1, housing, 2, imaging moiety, 3, storage area, 4, control section, 5, connector, 6, stube cable, 7, power pack, 8, increase the weight of part.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1 and Figure 2, the utility model ultradeep well downhole video imaging device, comprise housing, and be arranged on the control section in housing, described control section also is connected with respectively imaging moiety and storage area, described control section is connected with power pack by stube cable, and described power pack is connected with uphole equipment by the wire rope cable.
Also be equipped with and increase the weight of part on described housing.The preferred titanium alloy material of described housing makes.Described uphole equipment is logging truck.
Operating principle of the present utility model is as follows:
This equipment gathers video image by probe, then by logging truck wire rope cable, is transmitted the working portion of electric controller; After the energising of logging truck wire rope cable, equipment is started working, and gathers video, continuous extension along with depth-logger, video acquisition system is by continuous collecting oil well situation, and the depth of sampling depth need to be set up on their own according to different oil wells by the well workover personnel, after IMAQ finishes.The well-repairing work personnel are stored in the data acquisition in oil well in specific setup unit, after image data is processed, obtain the comprehensive hole condition video data that oil well has depth registration, then analyze the internal state of oil-well wall, carry out data and gather, instruct well-repairing work.
The shell that the utility model forms by the supporting miniature imaging of high Integrated design circuit unit can bear HTHP electromechanics---light all-in-one micro high definition imaging device is reflected to the various states of hole wall under oil well on the monitor on ground with analysing clearly, detect the situations such as crack, dislocation, trouble of lost tool in hole, drainage pore blockage and quicksand position of oil-well wall; Survey leakage and the damage of sleeve pipe or oil pipe; Survey knot watchtower in ancient times or microbe deposition.When being used as the boring detection, can observe the connection of casing coupling, the stopping state of the dislocation band on stratum, the corrosion of sleeve pipe and break situation and foreign material; Survey the output position of fluid and particulate, state etc.; Thereby provide reliable basis to the various situations of analyzing oil well.The utility model is simple in structure, reasonable in design, is the special structure form that well workover needs and different gas well well workovers need to design in conjunction with different downhole conditions according to the general super dark oil well of reality.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
