Embodiment 1

[0034] Such as Figure 1-3 As shown, a tight oil exploration device includes a fixed horizontal plate 1, and a pull pipe 2 is fixedly connected through the fixed horizontal plate 1. The upper end of the pull pipe 2 is connected with the hoisting equipment on the well, and both sides of the lower end of the fixed horizontal plate 1 are fixed. A fixed vertical board 3 is connected, the lower end of the fixed vertical board 3 is fixedly connected with a support seat 4, and a horizontally arranged sliding rod 5 is fixedly connected between the two fixed vertical boards 3, and a fixed tube 6 is provided outside the sliding rod 5 to draw the tube The lower end of 2 is fixedly connected with the side wall of the fixed pipe 6, and both sides of the fixed pipe 6 are provided with permanent magnetic sliders 7, and the two permanent magnetic sliders 7 attract each other with different poles, and the permanent magnetic sliders 7 are sleeved on the On the sliding rod 5, the middle part of ...

Embodiment 2

[0042] Such as Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that the reset mechanism 14 includes an elastic airbag 25, the elastic airbag 25 can be made of elastic rubber material, and one side of the elastic airbag 25 is fixedly connected with the side wall of the fixed riser 3, The other side of the elastic airbag 25 is in contact with the side wall of the rotating arm 11. The upper end of the elastic airbag 25 is fixedly connected with a one-way air intake valve 26, and the lower end of the elastic airbag 25 is fixedly connected with a one-way exhaust pipe 27.

[0043] One-way exhaust pipe 27 comprises L-shaped pipe 28, the horizontal section of L-shaped pipe 28 is fixedly connected with the side wall of horizontal fixing bar 10, and the opening of L-shaped pipe 28 vertical section is connected with elastic air bag 25, and L-shaped pipe 28 The opening of the horizontal section is fixedly connected with a one-way exhaust valve 29, and the ...

Embodiment 3

[0046] Such as Figure 6-7 As shown, the difference between this embodiment and Embodiment 2 is that: the support base 4 includes a connecting pipe 30, the upper end of the connecting pipe 30 is fixedly connected to the lower end of the riser 3, and the lower end of the connecting pipe 30 is fixedly connected with a second elastic corrugated Pipe 31, the second elastic bellows 31 is free to expand and contract along its axial direction, the lower end of the second elastic bellows 31 is fixedly connected with anti-skid seat 32, the upper end of connecting pipe 30 is connected with fixed pipe 6 through connecting pipe 33, permanent magnetic sliding The block 7 and the sliding rod 5 are connected in a sliding seal, and the threading hole of the fixed pipe 6 is provided with a sealing ring, so that the inside of the fixed pipe 6 forms an airtight space.

[0047] In this embodiment, when the permanent magnet slider 7 moves to both sides, the gas in the second elastic bellows 31 wil...

Abstract

The invention belongs to the field of oil exploration, and particularly relates to a tight oil exploration device. The tight oil exploration device comprises a fixed horizontal plate; the fixed horizontal plate is fixedly connected in a run-through mode with a pull tube; both sides of the lower end of the fixed horizontal plate are fixedly connected with fixed risers; the lower ends of the fixed risers are fixedly connected with supporting seats; a sliding rod horizontally arranged is fixedly connected between two fixed risers; the sliding rod is sleeved with a fixed tube; the lower end of thepull tube is fixedly connected with the side wall of the fixed tube; permanent magnetic sliding blocks are arranged at both sides of the fixed tube; two permanent magnetic sliding blocks are in a heteropole attraction relationship; the permanent magnetic sliding blocks sleeve the sliding rod; the middle part of the sliding rod is fixedly connected with an electromagnet; first elastic bellows arefixedly connected between the permanent magnetic sliding blocks and the fixed tube; the lower ends of the permanent magnetic sliding blocks are fixedly connected with fixed rods; and the opposite sidewalls of both two fixed risers are fixedly connected with horizontal fixed strips. The tight oil exploration device is simple to operate, has a good effect on tight sandstone and can help to improveexploration efficiency for tight oil.

Description

technical field [0001] The invention belongs to the field of petroleum exploration, in particular to a tight oil exploration device. Background technique [0002] Tight oil refers to the accumulation of oil formed without large-scale long-distance migration in tight reservoirs sandwiched in or close to high-quality oil-generating formations. It is an unconventional oil resource characterized by low porosity and low permeability. [0003] Tight oil exploration objects are different from conventional oil and gas reservoirs. The main exploration objects are tight sandstones or lacustrine carbonate rocks interbedded with main source rocks. The ultimate goal is to control the scale of tight oil reserves as a whole and provide beneficial reserves for development and production. However, the existing exploration equipment is difficult to operate when clamping tight sandstone, and the clamping effect is not good, and because tight oil is mainly distributed in the adjacent tight sand...
