[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. Petroleum exploration refers to the use of various exploration methods to understand the underground geological conditions in order to find and identify oil and gas resources. Generally, the terrain of petroleum exploration areas is relatively complex, with uneven ground depressions. Patent application number 202220748075 discloses an oil sampling device for oil geological exploration, including a device support base, a support column shell, a support beam shell, a support stabilization structure, a lifting structure, a sampling rod, and a sampling structure. The device support base is provided with a guide port, and the support column shell is vertically arranged on the device support base. The support column shell is symmetrically arranged in two sets about the vertical central axis of the device support base. However, this patent also has the following shortcomings: during the sampling process of underground oil wells, it is necessary to sample oil at different depths. Surface workers cannot keep track of the sampling depth of underground oil wells in a timely manner, which requires multiple samplings and reduces work efficiency. In response to this situation, a petroleum sampling device for petroleum geological exploration is proposed. Summary of the Invention

[0009] Preferably, the adjusting component further includes an adjusting bolt, the inner wall surface of the first movable plate is rotatably connected to the adjusting bolt, the surface of the adjusting bolt is rotatably connected to the second movable plate, the surface of the second movable plate is rotatably connected to a fixing ring, the surface of the fixing ring is fixedly connected to a roller, the surface of the roller is provided with a snap-fit groove, and the second movable plate is fixed by snap-fit between the snap-fit groove and the snap-fit block.
[0010] Preferably, the fixing component further includes a sliding groove on the surface of the moving plate, and a fixing plate is slidably connected to the surface of the sliding groove via a slider. A lifting block is fixedly connected to the surface of the fixing plate, and a claw is fixedly connected to the bottom of the fixing plate, which is then inserted and fixed to the ground.
[0011] Preferably, the filter component further includes a liquid storage ring, an inlet pipe fixedly connected to the bottom of the liquid storage ring, an absorber ball fixedly connected to the bottom of the inlet pipe, a telescopic rod fixedly connected to the top of the liquid storage ring, an outlet ball fixedly connected to the end of the telescopic rod away from the liquid storage ring, a telescopic bladder fixedly connected to the surface of the outlet ball, a filter plate fixedly connected to the inner wall surface of the second opening, an oil outlet block fixedly connected to the top of the filter plate, an absorber ball in contact with the surface of the oil outlet block, a collection tube fixedly connected to the top of the absorber ball, a locking block inserted into the inner wall surface of the collection tube, a cover plate fixedly connected to the top of the locking block, a pull handle fixedly connected to the top of the cover plate, and the bottom of the cover plate engaging with the surface of the first opening.

[0012] Preferably, the number of the inserts is set to eight, and the eight inserts are symmetrically installed on the surface of the arc plate with the center line of the extension block as the axis of symmetry. The sampling device is fixed by inserting and pulling the inserts into the ground.
[0013] Compared with the prior art, the present invention provides an oil sampling device for oil geological exploration, which has the following beneficial effects: 1. This invention, by setting an adjustment component, allows for the adjustment of the angle by dragging the first moving plate downwards. If the sampling height is insufficient, the angle of the second moving plate can be adjusted by rotating the adjustment bolt. The sampling tube is pushed to drive the roller to rotate on the surface of the fixed ring, thereby moving the position of the sampling device. After sampling is completed, the second moving plate is reset to the reset slot by adjusting the adjustment bolt. The second moving plate is fixed by the snap-fit between the snap-fit slot and the snap-fit block. By setting the above components, the sampling device can be moved effortlessly to perform multiple samplings.
[0014] 2. This invention, by setting a fixing component, allows the sampling device to be moved to the desired oil sampling location and its high speed adjusted. The fixing plate is then dragged downwards through the sliding groove by pulling the lifting block, and secured to the ground by the claws. In cases of steep terrain or strong winds, the sampling device may easily shift its position. The device can be laid flat on the ground through the lifting hole, and the sampling device is secured by the insertion or friction of the inserts on the arc plate surface with the ground, thus protecting the sampling device and maintaining its sampling position.
[0015] 3. This invention, by setting up a sensing component, uses a motor to drive the threaded plate to move up and down on the surface of the threaded rod. When it moves to the surface of the composite plate, the sensing block collides with the contact tube. The contact tube is subjected to pressure and expands and contracts within the telescopic tube. This pressure is transmitted through the sensing plate to the composite plate, and then through the two composite plates to the threaded rod. The vibration of the threaded rod causes the sampling device to vibrate. When the sensing block is impacted, the pressure is transmitted to the pressure-resistant balls. The pressure is released by the vibration of multiple pressure-resistant balls within the pressure-resistant plate, thereby protecting the threaded plate. By setting up the above components, when performing stratified sampling in oil wells at different depths, the vibration transmitted from the threaded plate to the top can alert the operator to the sampling device to reach a suitable sampling depth.
[0016] 4. This invention, by setting up a filtering component, allows the threaded plate to move to a certain depth in the oil well. The oil is then absorbed by the absorption ball and enters the storage ring through the inlet pipe. The oil is then fed into the outlet ball through the storage ring. After sampling, the threaded plate moves upward, bringing the outlet ball into contact with the filter plate. The compression bladder forces the oil inside the outlet ball into the filter plate. The filtered oil is absorbed by the oil outlet block. The absorption ball then absorbs the oil overflowing from the surface of the oil outlet block into the collection pipe. Finally, the collection pipe is removed from the filter pipe by pulling the handle, and the oil in the collection pipe is poured out by pulling out the locking block. By setting up the above components, oil can be automatically filtered within the sampling device, eliminating the need for secondary manual filtration and saving work efficiency.
