Description

Technical Field

[0001] The utility model relates to the technical field of oil production practice, in particular to an oilfield exploration sampler used in oil production practice. Background Art

[0002] Petroleum is a viscous, dark brown liquid known as the "blood of industry". Its main components are a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. In the process of oil production, oil field exploration samplers are usually used to sample petroleum.

[0003] For example, the Chinese utility model patent with authorization announcement number CN220251457U discloses an oilfield sampler for oilfield exploration, including a sampling barrel, a screw cap threaded on the bottom of the sampling barrel, a bracket fixedly connected to the top of the bracket, a fixing ring fixedly connected to the top of the fixing ring, and a traction rope fixedly installed inside the fixing ring. The utility model installs a pull ring and a brake line housing, etc., and after the sampling barrel is placed in the oil, the pull ring is pulled. Due to the traction of the brake line steel wire, the connecting plate can be driven to slide upward. When the oil inlet and the oil hole intersect, the oil in the oil well can quickly enter the interior of the sampling barrel for collection, thereby enhancing practicality. By arranging a sealing plate on the outer surface of the connecting plate, the sealing between the connecting plate and the sampling barrel can be strengthened to prevent the oil stored in the sampling barrel from leaking, thereby enhancing the sealing.

Specific embodiment 1

[0030] In order to solve the problem in the prior art that it is inconvenient to control the opening and closing of the oil barrel 2 and it is difficult to sample and store oil at different depths at the same time, the present embodiment adopts the following technical solutions, such as Figure 1 、 Figure 2 and Figure 4 During the oil production practice, the sampler can first be moved to the oil field exploration position through the mobile base 1, and then the oil barrel 2 can be removed from the inner side of the right upper end of the mobile base 1 and placed in the oil field exploration port. Then, the controller 11 embedded and installed on the inner side of the right rear upper end of the mobile base 1 can be used to control the winch 3 fixed by the clamp and screws on the upper left end of the mobile base 1 to operate, so that the connecting rope 4 wound on the inside of the winch 3 is unwound. Since the connecting rope 4 protruding from the outside of the winch 3 is fixed to the middle outer side of the lifting lug 5, and the lifting lug 5 is fixedly connected to the middle upper side of the oil barrel 2, the operation of the winch 3 facilitates the control of the oil barrel 2 to be retracted and extended in the oil field exploration port under its own counterweight through the wound connecting rope 4.

[0031] During the process of retracting and extending, the controller 11 can control the depth sensor 8 installed on the inner side of the upper end of the oil barrel 2 and powered by the battery 9 to cooperate with the display 10 installed on the inner side of the right rear upper end of the mobile base 1 to operate, so that the depth sensor 8 senses the position of the oil barrel 2, and the display 10 displays the data sensed by the depth sensor 8, so that the controller 11 can then control the solenoid valves 7 fixedly installed on the inner sides of the left and right ends of the oil barrel 2 to operate, so that the oil enters the oil chamber 6, and after the oil is produced, the solenoid valve 7 can be controlled to operate again to avoid oil leakage in the oil chamber 6. Since the oil chamber 6 is symmetrically opened inside the outer end of the oil barrel 2, and the solenoid valve 7 is correspondingly installed outside the oil chamber 6, it is convenient to sample and store oil at different depths in the oil barrel 2 at the same time. Specific embodiment 2

The controller 11 can then be used to control the solenoid valve 7 to operate so as to pour out the collected oil. After the oil is poured out, a cleaning liquid can be introduced into the oil chamber 6. The controller 11 can then be used to control the double-headed motor 16 in the oil barrel 2 powered by the battery 9 to operate, so that the double-headed motor 16 drives the second shaft bevel gear 15 connected to it to rotate. Since the outer side of the second shaft bevel gear 15 A first shaft-belt bevel gear 12 is meshed and connected perpendicular thereto. The first shaft-belt bevel gear 12 is located inside the middle of the oil chamber 6, and brushes 13 that are fitted with the oil barrel 2 are fixed at equal intervals above and below the first shaft-belt bevel gear 12. A sealing ring 14 that is fixed to the oil barrel 2 is tightly fitted on the outer side of the inner end of the first shaft-belt bevel gear 12, thereby facilitating the second shaft-belt bevel gear 15 to drive the first shaft-belt bevel gear 12 to rotate under the sealing of the sealing ring 14, thereby facilitating the first shaft-belt bevel gear 12 to drive the brush 13 to brush and clean the oil chamber 6;

[0033] After the sampler is used, it can be restored to its original position, and then the shielding cloth 17 fixed on the upper right side of the mobile base 1 can be pulled, so that the first Velcro 18 sewn under the shielding cloth 17 is connected to the second Velcro 19 fixed on the lower right side of the mobile base 1, so that the sampler can be shielded and protected by the shielding cloth 17.
