Description

Known instruments for measuring the curvature of wells with a t-shaped leg suspended on a ball suspension are known, are operated by a semiconductor influence of the washing liquid. In the proposed instrument for fixing the plumb in a fixed position, the slot of its ball suspension is located at the end The rod of the spring-loaded piston and the fixed bar for clamping the ball suspension in the socket are pushed into the hole of the rod. In Fig. 1 shows a longitudinal section of the device; Fig. 2 is a sectional section of the device perpendicular to the previous one; Fig. 3 is a side view of the machine Yes Determining the slope of the suspension.

In the housing 2 (FIG. L) of the device a piston 10 is placed with three guides 16 and a rod 5 on which a spiral spring 9 is worn, abutting against the bottom 15 of the housing. The rod 5, passing the nut 6 screwed into the bottom and pressing the stuffing box 12 pressed by it, ends with a slot 13 in which the plumb-type ball suspension 14 is placed 4. The hole in the

slit passes strap 7 (Fig. 1 and 2)

(four) .:

with a spike 8, fixedly fastened with the length of corpus 2.,

At the lower end of the housing 2, the cap 1 is screwed to cover the plumb line 4, and the upper end of the housing is screwed to the pipes. Above the piston 10 a spring ring is inserted into the cylinder And against the holes 18 made in the instrument walls. Above the bottom of the housing 2 there are holes 19 in the walls of the latter.

The onycKafoT device on the rod into the well at the desired depth. A projectile fluid is pumped by the pump, which pressurizes the piston 10. Suspension 14 is at this time clamped by process 8 of the strap 7. At 7-10 atm pressure of the piston K), overcome (the spring resistance 9) lowers and lowers the rod 5. The plumb-line rod 4, having freed itself from the sprout, hangs up on the suspension 14. At the same time, the guides 16 of the piston 10 with their 3atjH6aMH 17 shift the spring ring 11, which opens holes 1. Due to leakage through them my fluid pressure over piston 10 drops and piston with rod 5,

. Under the action of spring 9, returns to the initial position, and the suspension M is again pressed against the appendix 8 than the plumb line 4 and fixed in the position that it was right in accordance with the inclination of the device in the drill hole. In this case the spring ring P remains in cnymeHHdM coch: then, leaving the holes 18 open.

Holes 19, designed for

 eliminated compression-air; (and under the piston when it is lowered.

After the device is removed from the borehole, the body 2 is unscrewed 9T of the cylinder 3 and the cap 1 is screwed from it. Then the body is fastened in an inclined position on the machine 20 and is screwed in with the help of screw 21 in such a way that vertical position), then using the mountain jtOMa: a - determine the angle of deflection of the rod and, therefore, equal to it the angle of inclination of the well.

The invention.

Claims (1)

1. A device for measuring the curvature of wells with a heavy plumb suspended on a ball suspension, characterized in that, in order to fix the hole 4 in a stationary position, by clamping its ball / suspension 14, the socket 13 of the latter is located at the end of the rod 5 connected to the spring-loaded Porsch 10, moved under the pressure of the injected fluid), and progushche hole on the fixed bar 5 on the fixed bar 7, designed to clamp the ball suspension 14 in the slot 13 during the reverse movement of the piston 10 with the pin 5 under the action of the spring 9. 2: An apparatus according to claim 6, characterized by the use on the piston 10 of guides 16 serving for a spring ring 11, intended to open the holes 18 in the body of the instrument 2 in order to reduce the pressure of the liquid above. piston when lifting it. .
