[0002] In long-term oil production, oil well often appears that pumping rope is twisted and broken, weighted tubing or lead-filled tubing short section falls off and other phenomena, and the more the falling objects accumulate, the more complex the wellbore becomes, resulting in the oil well being in a shut-in state. In the maintenance and later maintenance of exploitation, the oil and water well needs to be maintained and repaired frequently, and the accumulated debris and floating objects in the well are fished to ensure the cleanliness of the well. The traditional deep well fishing operation is a very time-consuming and labor-consuming work, and the efficiency is low.

[0003] The existing patent for grant announcement number (CN213478278U) discloses an oil and water well repair fishing operation device, which comprises a fixing ring, a grab lever is hingedly connected to the lower surface of the fixing ring, and a plurality of grab levers are arranged in a ring array with the axis of the fixing ring as the center. In use, the screw rod is driven by the motor to rotate forward and reverse, driving the screw pipe to move upward or downward, the screw pipe moves upward to drive the connecting rod and the grab lever to move, driving the plurality of grab levers to move inward at the same time, thereby realizing the grabbing and fishing work of the bottom accumulation. Through the above structure, the utility model is more suitable for fishing large-sized debris, but it is difficult to stably grab some small-sized floating objects, thereby affecting the fishing efficiency.

[0004] To solve the above problems, we propose a fishing device for oil and water well to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0022] The technical solution in the embodiments of the present application is to solve the problems in the above background art, and the general idea is as follows: the fishing assembly is arranged in a reverse umbrella structure, in the use process, since the fishing assembly is in a straight rod shape in the folded state, the volume is small, and when it is lowered into the oil and water, it will not cause disturbance and stirring, so that the staff can quickly locate the position of the floating object and move the fishing assembly to the floating object; then the driving assembly is used to unfold and support the fishing umbrella cloth 6, and then the fishing assembly is lifted upwards, so that the fishing work of the small floating object in the oil and water well is realized, and since the fishing umbrella cloth 6 is arranged in a mesh structure, it also plays a role in solid-liquid separation during fishing.

[0023] Embodiment: refer to Figure 1 Figure 3 As shown in the figure, the fishing device for oil and water wells in the embodiment includes a mounting frame 1, a sliding sleeve 2 is arranged at the bottom middle part of the mounting frame 1, and a fishing assembly is arranged at the bottom of the sliding sleeve 2.

[0024] The fishing assembly is arranged in a reverse umbrella structure, including a fishing umbrella cloth 6, a first umbrella rib 61 and a second umbrella rib 62, the first umbrella rib 61 and the second umbrella rib 62 are movably connected, and are arranged at the inner side of the fishing umbrella cloth 6.

[0025] The driving assembly is used to unfold or close the fishing umbrella cloth 6, and includes a connecting column 4, the connecting column 4 is slidably arranged at the inner middle part of the sliding sleeve 2, a transmission screw rod 41 is arranged at the top of the connecting column 4, a through shaft type screw rod motor 8 is arranged at the upper middle part of the mounting frame 1, and the transmission screw rod 41 is movably arranged at the inner middle part of the through shaft type screw rod motor 8.

[0026] In the use process, the transmission screw rod 41 is provided with a limiting module, so that the transmission screw rod 41 is limited to linear motion, and is driven by the through shaft type screw rod motor 8 to move linearly, thereby driving the connecting column 4 to move up and down, when the connecting column 4 moves up, the first umbrella rib 61 and the second umbrella rib 62 are pushed by sliding with the sliding sleeve 2, so that the fishing umbrella cloth 6 is unfolded, and after the fishing umbrella cloth 6 is completely unfolded, the floating object in the oil and water well is fished by the fishing net.

[0027] ​The first umbrella rib 61 is movably installed at the bottom of the sliding sleeve 2, and the second umbrella rib 62 is movably installed at the bottom of the connecting column 4, and the first umbrella rib 61 and the second umbrella rib 62 are provided with multiple groups and are installed in a circumferential distribution, so that the supporting effect is improved.

[0028] In some examples, the protective cover 7 is threadedly installed in the middle of the upper end of the mounting frame 1, surrounds the outside of the through-shaft type screw rod motor 8, and can protect the through-shaft type screw rod motor 8.

[0029] In some examples, the load-bearing block 5 is installed at the bottom of the connecting column 4 and plays a load-bearing role, thereby improving the stability of the fishing device when it is lowered into oil water.

[0030] In some examples, the mounting frame 1 and the sliding sleeve 2 are fixedly connected through multiple connecting rods 3, the multiple connecting rods 3 surround the periphery of the connecting column 4, and the connecting rod 3 is arranged to limit and fix the sliding sleeve 2, thereby improving the stability of the connecting column 4 when it slides up and down in the middle of the sliding sleeve 2.

[0031] In some examples, the mounting frame 1 is provided with connecting ears 11 at the middle of both ends, which are used to install and fix the mounting frame 1, so that the fishing device can be installed on the lifting equipment of an oil-water well for lifting movement.

[0032] In some examples, the fishing umbrella cloth 6 is provided in a mesh structure, can filter oil water, and plays a solid-liquid separation role.

[0033] The working principle of the utility model is:

[0034] In use, first, the connecting ears 11 at both ends of the mounting frame 1 are used to install the fishing device on the lifting equipment of an oil-water well, and then the lifting equipment is used to lower the fishing device into the oil-water well.

[0035] Since the fishing assembly of the fishing device is in a straight rod shape in the retracted state, it has a small volume and does not cause disturbance to oil water when it is lowered into the oil water, so it can be directly lowered near the floating object.

[0036] When the fishing umbrella cloth 6 is lowered below the floating object, the through-shaft type screw rod motor 8 can be started at this time to drive the transmission screw rod 41 to move linearly, when the transmission screw rod 41 slides upwards, the connecting column 4 is pulled upwards, when the sliding sleeve 2 is in a fixed form, the first umbrella rib 61 is pushed, so that the first umbrella rib 61 and the second umbrella rib 62 are rotated, so that the fishing umbrella cloth 6 is unfolded and supported, when the fishing umbrella cloth 6 is fully supported, the surface is funnel-shaped, so that the floating object is netted and fished, at this time, the fishing device is lifted by the lifting device, and the oil and water are filtered from the leakage hole of the fishing umbrella cloth 6, so that the solid-liquid separation is realized.

[0037] The utility model discloses a structure, thereby realize to the small floating object of oil and water well, and, because fishing umbrella cloth 6 is set up as the screen structure, make in the process of fishing, still play the role of solid-liquid separation.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The skilled person in the art should understand that the utility model is not limited by the above examples, and the above examples and the description in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
