Description

Technical Field

[0001] The invention belongs to the technical field of petroleum exploration, and in particular relates to a measuring device used for petroleum geological exploration. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence. Petroleum is divided into crude oil, natural gas, natural gas liquid and natural tar, but it is customary to use "petroleum" as the definition of "crude oil". Petroleum is a viscous, dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust. The main component is a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. Petroleum is one of the main objects of geological exploration. The detection instrument used by the oil exploration team is also called a triaxial measuring instrument. A seismic detector is installed inside the measuring instrument. The detection head is placed in the XYZ three-axis direction, so it is called a triaxial measuring instrument. When the measuring instrument is used, it is nailed to the ground according to the distance. Explosives are installed at designated locations on the ground. The seismic fluctuations generated by the explosion of the explosives will be sensed in the measuring instrument, and then the measuring instrument converts the mechanical signal of this fluctuation into an electric wave signal and feeds it back to a dedicated display instrument. The waveform display of the display instrument can tell the underground structure and determine whether there is petroleum. However, most of the existing measuring instruments need to be fixed by brackets when in use, but the stability of most of the existing fixed brackets is not very good, and the environment of oil exploration is relatively harsh, so the measuring instruments are prone to loose fixation. At the same time, the existing measuring instruments lack effective protective devices and are easily damaged by external impacts during use, which not only affects the service life of the measuring instruments, but also affects the progress of oil geological exploration and detection.

[0015] The gripper 21 comprises a turning handle 12, a third threaded shaft 13, a sliding member 14, a guide rod 15, a fixing claw 16, a connecting block 17, a sliding rod 18, a connecting spring 19 and a fixing member 20; the upper end of the turning handle 12 is connected to the lower end of the supporting leg 11 in a rotatable manner, and the lower end of the turning handle 12 is connected to the upper end of the third threaded shaft 13; the sliding member 14 is spirally connected to the outside of the third threaded shaft 13; the left and right sides of the sliding member 14 are respectively hinged to the upper end of a guide rod 15, and the lower ends of the two guide rods 15 are respectively hinged to the upper outer side of a fixing claw 16; the sliding rod 1 The upper end of 8 is fixedly connected to the lower end of the third threaded shaft 13, and the lower end of the sliding rod 18 is connected to the upper end of the fixing member 20; the connecting spring 19 is sleeved on the lower part of the sliding rod 18, and the lower end is fixedly connected to the top of the fixing member 20; the middle part of the connecting block 17 is sleeved on the upper part of the sliding rod 18, and the two sides are respectively hinged to the upper end of a fixing claw 16; the fixing claw 16 and the lower end of the fixing member 20 are inserted into the ground, so that the measuring instrument 4 can be effectively fixed to avoid the problem of loose fixation due to the harsh environment of oil exploration, and the operation is simple, which is convenient for installation operation.

[0016] There are four buffer springs 9 in total, which are arranged at equal distances, and such a buffering effect is better.

[0017] The buffer pad 10 is made of a rubber sheet and can provide good protection for the measuring instrument 4 .

[0018] The fixing member 20 is an inverted quadrangular pyramid structure.

[0019] The rotation angle of the fixing claw 16 is 0° to 60°, which is convenient for achieving effective fixing.

[0020] The following is an explanation of the use of the measuring device used in petroleum geological exploration:

[0021] The electrical appliances used in this device are all powered by built-in batteries. When in use, the staff first places the device on the ground, and then rotates the adjusting knob to rotate the first threaded shaft 2 to move the two clamping plates 3 toward each other until the two clamping plates 3 firmly fix the two sides of the measuring instrument 4, and at the same time rotates the second threaded shaft 6 on the inner side of the fixing plate 5, thereby driving the slider 7 to slide downward. Driven by the slider 7, the clamping plate 8, the buffer spring 9 and the buffer pad 10 also move downward together until the buffer pad 10 is tightly attached to the top surface of the measuring instrument 4. At this time, with the cooperation of the buffer spring 9 and the buffer pad 10, the measuring instrument 4 can be effectively protected to prevent the measuring instrument 4 from being damaged by external force during use. This can greatly extend the service life of the measuring instrument 4 and avoid affecting the progress of petroleum geological exploration and detection. At the same time, the handle 12 under the leg 11 can be rotated to drive the third threaded shaft 13 to rotate. At this time, since the fixing claw 16 and the fixing member 20 are in contact with the ground, the fixing claw 16 can be prevented from rotating. At this time, with the cooperation of the guide rod 15 and the connecting block 17, the angle between the fixing claw 16 and the ground can be changed, thereby improving the grip, and the fixing member 20 can be moved downward in a rotating manner. At the same time, with the cooperation of the sliding rod 18 and the connecting spring 19, the fixing member 20 can be firmly embedded in the ground, so that the measuring instrument 4 can be effectively supported and fixed, avoiding the problem of loose fixation due to the harsh environment of oil exploration, and the operation is simple, which is convenient for installation.
