Description
Technical field
The utility model relates to well logging field, particularly a kind of horizontal wellbore logging guide device for well-opening cable.
Background technology
In prior art, when logging well, needing cable to transfer and sending into down-hole.But, crinoline complex structure of the prior art, be not easy to regulate the position of cable, easily cause the damage and wear of cable.
Utility model content
The utility model provides that a kind of structure is simple, cost is low, fitting operation is convenient, can protect the horizontal wellbore logging guide device for well-opening cable of cable.
For solving the problem, as an aspect of the present utility model, provide a kind of horizontal wellbore logging guide device for well-opening cable, comprise: casing adapter, upper end inwall has arc lead angle, lower end has stepped hole, and the sidewall of stepped hole is provided with lock-screw, is formed with vertically through cable punching hole in casing adapter; First supporting vertical plate, welds with the outer surface of casing adapter; Second supporting vertical plate, with the first supporting vertical plate position adjustments be connected, and be positioned at the side of the cable punching hole of the close casing adapter of the first supporting vertical plate; Multiple first roller, is arranged on the side away from the first supporting vertical plate of the second supporting vertical plate, and multiple first roller is by the first arching trajectory arrangement; Multiple second roller, is removably mounted on the side away from the first supporting vertical plate of the second supporting vertical plate, and multiple second roller is by the second arching trajectory arrangement; Cable guide channel is formed between multiple first roller and multiple second roller.
Preferably, horizontal wellbore logging guide device for well-opening cable also comprises and is arranged on photoelectric encoder in the second supporting vertical plate and for the detection signal that gathers photoelectric encoder and the wireless detection device of being gone out by detection signal wireless transmission.
Owing to have employed technique scheme; the utility model is when to delivered downhole cable; can prevent cable from being damaged by the upper end-face edge of casing adapter, go back the position of adjustable cable in casing adapter avoid cable wear and tear and the curve that the first roller and the curved setting of the second roller are bent naturally to meet cable; be conducive to protection cable can not fracture, have that structure is simple, cost is low, fitting operation feature easily.
Accompanying drawing explanation

Fig. 2 schematically shows the location diagram of casing adapter and the first supporting vertical plate;
Fig. 3 schematically shows the structural representation of casing adapter.
Reference numeral in figure: 1, casing adapter; 2, arc lead angle; 3, stepped hole; 4, the first supporting vertical plate; 5, the second supporting vertical plate; 6, the first roller; 7, the second roller; 8, lock-screw; 9, cable.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Please refer to Fig. 1 to Fig. 3, the utility model provides a kind of horizontal wellbore logging guide device for well-opening cable, comprise: casing adapter 1, upper end inwall has arc lead angle 2, lower end has stepped hole 3, the sidewall of stepped hole 3 is provided with lock-screw 8, in casing adapter 1, is formed with vertically through cable punching hole; First supporting vertical plate 4, welds with the outer surface of casing adapter 1; Second supporting vertical plate 5, with the first supporting vertical plate 4 position adjustments be connected, and be positioned at the side of the cable punching hole of the close casing adapter 1 of the first supporting vertical plate 4; Multiple first roller 6, is arranged on the side away from the first supporting vertical plate 4 of the second supporting vertical plate 5, and multiple first roller 6 is by the first arching trajectory arrangement; Multiple second roller 7, is removably mounted on the side away from the first supporting vertical plate 4 of the second supporting vertical plate 5, and multiple second roller 7 is by the second arching trajectory arrangement; Cable guide channel is formed between multiple first roller and multiple second roller 7.
During use, lock-screw 8 tightened by sleeve pipe casing adapter 1 being enclosed within well place, then the second roller 7 is pulled down, cable 9 is placed on multiple first roller 6, and then multiple second roller 7 is installed in the second supporting vertical plate 5, thus cable 9 is clamped in cable guide channel that the first roller 6 and the second roller 7 formed, cable 9 can be broadcasted to down-hole.In addition, also can pass through the installation site of the second supporting vertical plate 5 in the first supporting vertical plate 4, regulate the position of cable 9 in cable punching hole, prevent cable 9 and casing wall from rubbing.Upper end due to casing adapter 1 has arc lead angle 2, therefore, when making cable 9 contact with the upper end-face edge of casing adapter 1 in neglectful situation, also can not damage cable 9 because of the corner angle of casing adapter top edge.First roller 6 and the curved setting of the second roller 7, met the curve that cable bends naturally, and being conducive to protection cable can not fracture.
Owing to have employed technique scheme; the utility model is when to delivered downhole cable; can prevent cable from being damaged by the upper end-face edge of casing adapter, go back the position of adjustable cable in casing adapter avoid cable wear and tear and the curve that the first roller 6 and the curved setting of the second roller 7 are bent naturally to meet cable; be conducive to protection cable can not fracture, have that structure is simple, cost is low, fitting operation feature easily.
Preferably, horizontal wellbore logging guide device for well-opening cable also comprises and is arranged on photoelectric encoder in the second supporting vertical plate 5 and for the detection signal that gathers photoelectric encoder and the wireless detection device of being gone out by detection signal wireless transmission.Like this, what can adopt cable in real time transfers the degree of depth, and can adopt wireless mode, depth signal is sent, avoids field wiring, improves the antijamming capability of signal.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
