Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] As shown in Figure 1 - Figure 5 indicated, the utility model provides: as Figure 1 - Figure 5 indicated, the utility model provides: a casing pressure data collector for oil field, including base 10 and hoop 30 of ring in the base 10 outside, and the measuring device 20 of setting at the top of base 10, the base 10 includes the flange plate 13 of communicating with pipeline and cooperate the thickened expansion pipe 12 of fixing in the lateral wall of flange plate 13 of hoop 30, the measuring device 20 includes collector 40 and installs the support plate 21 of one-way communication at the top of thickened expansion pipe 12, the collection end of collector 40 is communicated with thickened expansion pipe 12 after penetrating support plate 21,

[0027] Support plate 21 is provided with measuring hole 22, and measuring hole 22 is communicated with the inside of thickened expansion pipe 12, so that collector 40 can accurately collect the pressure data in the pipeline, and measuring device 20 further includes movable plate 23, movable plate 23 is connected with support plate 21 through pin shaft 24, and can rotate around pin shaft 24, so that the closure of measuring hole 22 is adjusted, and the sealing condition in thickened expansion pipe 12 is ensured, adjusting ring 31 is arranged on hoop 30, a plurality of adjusting holes 32 are formed in adjusting ring 31, and the fixing force of hoop 30 on base 10 and pipeline can be conveniently adjusted by adjusting tension device, so that the stability and reliability of data base 10 are ensured.

[0028] Specifically, as shown in Figure 1 : the base 10 further includes a plurality of screws 11 evenly distributed on the top of the thickened expansion pipe 12 for fixing the thickened expansion pipe 12 and the support plate 21;

[0029] These screws 11 not only enhance the stability of the connection between the thickened expansion pipe 12 and the support plate 21, but also ensure the structural strength of the entire base 10 and the stability of the placement of the collector 40.

[0030] Specifically, as shown in the figure: Figure 2 The measuring device 20 further comprises a measuring hole 22 opened on the support plate 21, and the inner wall of the measuring hole 22 is provided in a threaded manner;

[0031] So that the measuring hole 22 can be sealed with the threaded detection rod, when data collection is needed, the detection rod can be simply screwed in to make the detection rod communicate with the inside of the thickened expansion pipe 12, so that the collector 40 can collect data, and the threaded design also enhances the sealing effect between the detection rod and the measuring hole 22, further improving the accuracy and reliability of data collection.

[0032] Specifically, as shown in the figure: Figure 5 The lower surface of the support plate 21 is fixed with a pin shaft 24, and the pin shaft 24 movably accommodates an activity plate 23 that can be opened and closed within a thirty-degree angle range, and the top of the activity plate 23 is provided with a sealing layer that blocks the measuring hole 22;

[0033] The design that the activity plate 23 is connected to the support plate 21 through the pin shaft 24 enables the activity plate 23 to be opened and closed within a thirty-degree angle range around the pin shaft 24, which not only facilitates the adjustment of the closure of the measuring hole 22, but also ensures the sealing conditions inside the thickened expansion pipe 12, avoiding data collection errors caused by poor sealing. When the activity plate 23 is closed, the sealing layer tightly fits the edge of the measuring hole 22, forming an effective sealing barrier to prevent external impurities or gases from entering the thickened expansion pipe 12, ensuring the accuracy of data collection.

[0034] Specifically, as shown in the figure: Figure 2 The detection end of the collector 40 is threaded through the support plate 21 and opens the pressure-closed activity plate 23;

[0035] When the detection rod is screwed into the measuring hole 22 and opens the activity plate 23, the activity plate 23 rotates around the pin shaft 24 to expose the measuring hole 22, allowing the detection rod to smoothly enter the inside of the thickened expansion pipe 12, which not only ensures sufficient opening and closing space, but also avoids the problem of structural instability caused by excessive opening and closing, ensuring the stability and reliability of the entire data collector base.

[0036] Specifically, as shown in the figure: Figure 1 The clamp 30 comprises an adjusting ring 31 fitted on the side wall, the adjusting ring 31 is provided with a tensioning device composed of a rotating threaded column and the base 10, and a plurality of adjusting holes 32 are uniformly provided on the adjusting ring 31 to engage and tightly hold the rotating threaded column;

[0038] Specifically, as shown in the figure: Figure 1 The thickened expansion pipe 12 is a rubber material with double-layer rubber and a steel mesh interlayer.

[0039] Such a special material not only increases the good elasticity and wear resistance of the thickened expansion pipe 12, but also greatly enhances the compression strength and corrosion resistance. In the complex working environment of the oil field, the thickened expansion pipe 12 needs to withstand the huge pressure from the underground oil and gas, and also needs to resist the erosion of oil, water, sand and other media. Therefore, the rubber material with double-layer rubber and a steel mesh interlayer is selected. In addition, the material also has good sealing performance, which can effectively prevent oil and gas leakage and ensure the accuracy of data acquisition.

[0040] The base 10 is placed on the oil port pipe diameter that needs to be measured, the adjusting ring 31 attached to the side wall of the thickened expansion pipe 12 is adjusted to a size suitable for the oil port pipe diameter, the rotating threaded column fixed on the adjusting ring 31 is matched with the adjusting holes 32 opened on the adjusting ring 31, the adjusting ring 31 is tightened, the base 10 is fixed on the oil port pipe diameter, the detector 40 is inserted into the measuring hole 22 opened on the support plate 21, the movable plate 23 fixed on one side of the measuring hole 22 by the pin shaft 24 is opened upward when the detection end is inserted, the sleeve pressure is detected, the detection rod is pulled out upward after detection, the movable plate 23 is closed upward at the same time, and the pressure in the thickened expansion pipe 12 also drives the movable plate 23 to close upward, so as to block the measuring hole 22, ensure that the thickened expansion pipe 12 is in a sealed environment, and the movable plate 23 is provided with a sealing layer to ensure that the thickened expansion pipe 12 is in a sealed environment. The flange plate 13 at the bottom of the base 10 leaks the pressure in the thickened expansion pipe 12, whether the thickened expansion pipe 12 is inflated or contracted is observed, whether the sleeve pressure needs to be detected is judged, inflation indicates that the sleeve pressure at the oil port is too large and needs to be measured, and no inflation indicates that the sleeve pressure at the oil port is within the normal pressure value and does not need to be detected.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
