Description

Technical Field

[0001] The utility model relates to the technical field of petroleum well logging, in particular to a tension depth measuring device for petroleum well logging. Background Art

[0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry". Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. Currently, the depth of oil wells needs to be measured before exploitation.

[0003] For example, the Chinese utility model provides "a depth measuring device for oil well logging", announcement number: CN214091846U, which includes a base plate, an output shaft of a driving motor passes through a support and is fixedly connected to a rope winding shaft, a steel wire rope slidably connected to a pulley is wound around the outer side of the rope winding shaft, one end of the steel wire rope is fixedly connected to a sinker, casings are fixedly installed on the front and rear surfaces of the base plate, push rods are movably connected inside the two casings, connecting blocks are symmetrically fixedly installed on the outer side of the push rods, a servo motor is fixedly installed on the outer side of the casing, a lead screw is fixedly connected to the output shaft of the servo motor, a threaded tube fixedly connected to the connecting block is screwed on the outer side of the lead screw, and the servo motor is started to drive the lead screw connected to its output shaft to rotate, so that the threaded tube on the outer side drives the push rod connected through the connecting block to rise and fall, thereby solving the problem that the existing depth measuring device is inconvenient to adjust the height of the push rod according to needs when in use, making it difficult to adapt to users of different heights.

[0026] Embodiment 2:

[0027] On the basis of embodiment 1, the present invention is as follows Figure 1-Figure 4 As shown, a horizontal plate 13 is fixedly connected to the upper end of the left side of the outer surface of the support frame 15, and the number of the horizontal plates 13 is two.

[0028] In the present technical solution, the purpose of guiding the measuring rope 8 is achieved by setting the cross plate 13 and the guide wheel 12, and a large horizontal displacement of the measuring rope 8 and the sinker 14 is avoided during the downward movement. The purpose of guiding the measuring rope 8 is achieved by setting the U-shaped limit frame 9, and the measuring rope 8 is avoided from slipping off the two sides of the support wheel 19 during the unwinding process. The setting of the brake caster 4 and the handrail 5 facilitates the movement and support of the whole by personnel. The setting of the guide groove 25 and the guide block 26 achieves the purpose of guiding the mobile frame 20, and avoids the movement. The movable frame 20 tilts during the movement. Through the setting of the limit hole 16, the adjusting screw 18 and the U-shaped limit rod 17, the U-shaped limit rod 17 can be driven to move under the action of the rotation of the adjusting screw 18 until the U-shaped limit rod 17 can be inserted into the surface of the limit hole 16, so that the winding drum 7 can be effectively locked and limited to avoid the winding drum 7 from rotating due to force or inertia during the moving and transportation process, and causing the measuring rope 8 to loosen.

The pressure is reduced, and at the same time, the support spring 24 is pre-compressed and tensile, which can push the movable frame 20, the magnetic block 23 and the support wheel 19 to move upward. The magnetic block 23 can contact the bottom of the magnetic control switch 22 under the action of the movement, and the contacts inside the magnetic control switch 22 are connected under the action of the magnetic force of the magnetic block 23, so that the sound and light alarm 10 can work, and when the sinker 14 contacts the bottom of the oil well and causes the measuring rope 8 to relax and the tension changes, it can give an alarm to the surrounding staff, so that the staff can promptly discover and stop the unwinding operation of the measuring rope 8, effectively avoiding the measuring rope 8 being continuously unwound and entangled inside the oil well, thereby bringing great convenience to the measurement work of the staff.
