Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction technology, and in particular to an oil and gas overflow treatment device for oil testing ports. Background Technology

[0002] Oil testing, also known as reservoir testing or formation testing, refers to the determination and testing of the oil and gas production capacity, fluid properties, and reservoir characteristics of potential oil-bearing reservoirs with oil and gas indications.

[0019] As an optional method for handling oil and gas overflow at the oil test port, the sealing assembly includes:

[0020] A sealing elastic element is provided vertically, with its lower end fixedly disposed in the lower cavity;

[0021] A sealing cover plate is fixedly installed at the upper end of the sealing elastic element;

[0022] When the sealing elastic element is in a free state, the sealing cover plate can block the flow hole; when the sealing elastic element is under pressure, the sealing cover plate can open the flow hole.

[0023] As an optional method for handling oil and gas overflow at the oil test port, the sealing cover includes:

[0024] The pressure-bearing part is coaxially arranged with the flow hole and has a diameter smaller than that of the flow hole;

[0025] A blocking part is coaxially connected to the lower surface of the pressure receiving part. The blocking part is coaxially arranged with the flow hole and its diameter is equal to the diameter of the flow hole. The gas filter assembly can apply pressure to the pressure receiving part to make the blocking part open the flow hole.

[0026] As an optional feature of the oil and gas overflow treatment device at the oil test port, the flow hole includes:

[0027] Small diameter hole;

[0028] The large-diameter hole is coaxially located below the small-diameter hole. When the sealing elastic element is in a free state, the pressure-bearing part is movably located inside the small-diameter hole, and the sealing part seals the large-diameter hole.

[0036] The beneficial effects of this utility model are:

[0037] When in use, the oil vapor overflow treatment device for the oil test port is installed with the first cylinder fixedly attached to the outlet end of the oil test port, ensuring that the opening at the lower end of the first cylinder is connected to the outlet end of the oil test port. When oil vapor overflows from the oil test port, the overflowing oil vapor flows through the inner cavity of the first cylinder into the lower cavity, where the oil in the oil vapor accumulates under its own gravity. At this time, the oil vapor overflow treatment device is in operation, so the gas filter assembly is installed and pressurizes the sealing assembly. The gas in the overflowing oil vapor then flows through the flow hole to the gas filter assembly, where it is filtered and discharged.

[0038] In other words, the oil and gas overflow treatment device at the oil test port mentioned above can collect the oil in the overflow oil and gas and filter the gas in the overflow oil and gas. The gas will be discharged only after being filtered, thereby avoiding or reducing the pollution of the external environment caused by the overflow oil and gas. Attached Figure Description

[0059] Example 1

[0060] See Figures 1-4 This embodiment provides an oil and gas overflow treatment device for oil testing port, which is used to treat the oil and gas overflowing from the oil testing port during oil testing operations, and can avoid or reduce the pollution of the external environment caused by the overflowing oil and gas.

[0061] Specifically, in this embodiment, the oil and gas overflow treatment device at the oil test port includes a first cylinder 1, a second cylinder 2, a sealing component 3, and a gas filter component 4.

[0062] The first cylinder 1 has an inner cavity 12 with an opening at its lower end, and the opening at the lower end of the first cylinder 1 is configured to communicate with the outlet end of the oil test port.

[0063] Optionally, a connecting flange is provided at the lower end of the first cylinder 1 so that the first cylinder 1 can be fixedly installed at the outlet end of the oil test port, thereby making the opening at the lower end of the first cylinder 1 connected to the outlet end of the oil test port.

[0064] The second cylinder 2 includes a second cylinder body 21. A partition 22 is provided inside the second cylinder body 21. The partition 22 divides the inner cavity of the second cylinder body 21 into an upper cavity 211 and a lower cavity 212. The lower cavity 212 is connected to the inner cavity 12 of the first cylinder. A flow hole 221 is provided through the partition 22.

[0065] The sealing component 3 is disposed in the lower cavity 212. In a free state, it can seal the flow hole 221, and in a pressurized state, it can open the flow hole 221.

[0066] The gas filter assembly 4 is detachably installed in the upper cavity 211 and its lower end can communicate with the flow hole 221. The gas filter assembly 4 can apply pressure to the sealing assembly 3.

[0067] In this embodiment, the oil and gas overflow treatment device for the oil test port is used by fixing the first cylinder 1 to the outlet end of the oil test port, and making the opening at the lower end of the first cylinder 1 connected to the outlet end of the oil test port. When oil and gas overflows from the oil test port, the overflowing oil and gas overflows through the inner cavity 12 of the first cylinder into the lower cavity 212. The oil in the oil and gas will accumulate in the lower cavity 212 under its own gravity. At this time, the oil and gas overflow treatment device for the oil test port is in working condition, so the gas filter component 4 is in the installed state and applies pressure to the sealing component 3. The gas in this oil and gas will flow to the gas filter component 4 through the flow hole 221, and the gas will be discharged after being filtered by the gas filter component 4.

[0068] In other words, the oil and gas overflow treatment device at the oil test port mentioned above can collect the oil in the overflow oil and gas and filter the gas in the overflow oil and gas. The gas will be discharged only after being filtered, thereby avoiding or reducing the pollution of the external environment caused by the overflow oil and gas.

[0069] Understandably, during actual operation, oil and gas will first accumulate in the inner cavity 12 of the first cylinder, and the gas in the oil and gas will enter the lower cavity 212 first. Only when the oil level in the inner cavity 12 of the first cylinder is level with the connection between the lower cavity 212 and the inner cavity 12 of the first cylinder will the oil begin to enter the lower cavity 212.

[0070] Example 2

[0071] This embodiment is a further improvement on the first embodiment.

[0072] Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described.

[0073] Specifically, the difference lies in the fact that, in this embodiment, the oil and gas overflow treatment device at the oil test port can also detect the overflowing oil and gas.

[0074] Specifically, see Figure 1 and Figure 2 In this embodiment, in order to detect the overflowing oil and gas, the oil and gas overflow treatment device at the oil test port also includes a monitoring component 5.

[0075] The monitoring component 5 includes a drive rod 51, a piston plate 52, and a barometer 53.

[0076] The drive rod 51 is disposed in the first cylinder 1 and the drive end is located in the inner cavity 12 of the first cylinder. The drive end of the drive rod 51 can extend and retract.

[0077] Optionally, in this embodiment, the drive rod 51 is an electric push rod.

[0078] The piston plate 52 is fixedly disposed at the lower end of the drive end of the drive rod 51 and is slidably and sealingly connected to the inner wall of the inner cavity 12 of the first cylinder. The piston plate 52 can move to a position higher or lower than the connection point of the first cylinder 1 and the second cylinder 2.

[0079] The air pressure detector 53 is located on the lower side of the first cylinder 1 and is connected to the inner cavity 12 of the first cylinder.

[0080] Specifically, when the oil test port oil vapor overflow treatment device is working, the piston plate 52 is controlled by the drive rod 51 to move to a position lower than the connection between the first cylinder 1 and the second cylinder 2. At this time, the stationary piston plate 52 is sealed to the inner wall of the inner cavity 12 of the first cylinder. Therefore, the oil vapor overflowing from the oil test port will accumulate in the inner cavity 12 of the first cylinder. As the accumulated oil vapor increases, the air pressure detector 53 can detect the air pressure in the inner cavity 12 of the first cylinder in real time. The staff can know the air pressure in the inner cavity 12 of the first cylinder by observing the reading of the air pressure detector 53.

[0081] Alternatively, the barometer 53 is electrically connected to an alarm. When the barometer 53 detects a value that reaches a preset threshold, the barometer 53 transmits a signal to the alarm, which then triggers an alarm to alert the staff.

[0082] Alternatively, when the alarm sounds, the drive end of the drive rod 51 will retract to pull the piston plate 52 above the connection between the first cylinder 1 and the second cylinder 2, at which point gas enters the second cylinder 2.

[0083] Optionally, in this embodiment, the first cylinder 1 and the second cylinder 2 are connected by a connecting pipe 6, thereby realizing the communication between the inner cavity 12 and the lower cavity 212 of the first cylinder.

[0084] Furthermore, a one-way valve 61 is provided on the connecting pipe 6, which allows oil and gas to flow only from the first cylinder 1 to the second cylinder 2.

[0085] Alternatively, in this embodiment, a gas-sensitive probe (not shown in the figure) is provided in the lower cavity 212, which is used to detect the composition of oil and gas.

[0086] Specifically, a gas-sensitive probe is a gas sensor, which is a device that converts information such as the composition and concentration of a gas into information that can be used by personnel, instruments, computers, etc. The structure and principle of gas sensors are existing technology and will not be described in detail here.

[0087] Further, see Figure 2A filter screen 11 is installed inside the inner cavity 12 of the first cylinder. The filter screen 11 is always located below the piston plate 52. The lower surface of the piston plate 52 is provided with cleaning needles 521 that correspond one-to-one with the mesh openings of the filter screen 11.

[0088] The filter screen 11 can perform preliminary filtration of oil and gas overflowing from the oil test port, preventing larger solid impurities from entering the inner cavity 12 of the first cylinder.

[0089] The cleaning needle 521 can clean the mesh of the filter screen 11, preventing the mesh of the filter screen 11 from becoming clogged after long-term use and affecting the normal use of the oil and gas overflow treatment device at the oil test port.

[0090] Specifically, when it is necessary to clean the mesh of the filter screen 11, the drive end of the drive rod 51 extends and drives the piston plate 52 to move down. The piston plate 52 drives the cleaning needle 521 to move down, and the cleaning needle 521 passes through the mesh to clean the mesh.

[0091] Optionally, in this embodiment, the mesh openings on the filter screen 11 are arranged in a ring array, and there are multiple ring arrays. Correspondingly, there are also multiple cleaning needles 521, and the cleaning needles 521 are arranged one-to-one with the mesh openings.

[0092] Example 3

[0093] This embodiment is a further improvement on the first embodiment.

[0094] Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described.

[0095] Specifically, in this embodiment, see Figures 2-5 The gas filter assembly 4 includes a gas filter cylinder 41, a filter element 42, and a lower cover 43 for the gas filter cylinder.

[0096] The gas filter cylinder 41 is detachably installed in the upper cavity 211, and the gas filter cylinder 41 has a gas filter cylinder cavity 411 that runs through it from top to bottom.

[0097] The filter element 42 is disposed inside the gas filter cylinder cavity 411, and the filter element 42 can filter particulate matter carried in the gas.

[0098] The lower cover 43 of the gas filter cylinder is installed at the lower end opening of the gas filter cylinder cavity 411. The lower cover 43 of the gas filter cylinder has a through hole 431 that can communicate with the flow hole 221. The lower cover 43 of the gas filter cylinder can apply pressure to the sealing component 3.

[0099] Specifically, when the gas filter assembly 4 is installed in place, the lower cover 43 of the gas filter cylinder applies pressure to the sealing assembly 3, causing the sealing assembly 3 to open the flow hole 221. At this time, the flow hole 221 is connected to the perforation 431. The gas overflowing into the lower cavity 212 enters the gas filter cylinder 41 through the flow hole 221 and the sealing assembly 3 in sequence, and is filtered by the filter element 42 in the gas filter cylinder 41, and finally overflows from the upper opening of the gas filter cylinder 41.

[0100] Further, see Figure 5 In this embodiment, the gas filtration assembly 4 further includes a first filter element annular clamping member 44 and a second filter element annular clamping member 45.

[0101] The first filter element annular clamping member 44 is fixedly installed inside the gas filter cylinder cavity 411.

[0102] The second filter element annular clamping member 45 is detachably disposed inside the gas filter cylinder cavity 411 through the upper opening and is spaced above the first filter element annular clamping member 44. The filter element 42 is clamped between the first filter element annular clamping member 44 and the second filter element annular clamping member 45.

[0103] The first filter element annular clamping member 44 and the second filter element annular clamping member 45 are both annular, so that they will not interfere with the normal discharge of gas.

[0104] Optionally, in this embodiment, the first filter element annular clamping member 44 is integrally formed with the gas filter cylinder 41 to achieve a fixed connection between the two.

[0105] The second filter element annular clamping member 45 is detachably connected to the gas filter cylinder cavity 411 by means of threaded installation.

[0106] More specifically, in this embodiment, when installing the filter element 42, the second filter element annular clamping member 45 is first in a disassembled state. The filter element 42 is first placed from the upper opening of the gas filter cylinder cavity 411 onto the first filter element annular clamping member 44. Then, the second filter element annular clamping member 45 is screwed until the second filter element annular clamping member 45 abuts against the upper surface of the filter element 42. In this way, the filter element 42 is clamped, and the rising gas impact is prevented from causing the filter element 42 to shift.

[0107] Meanwhile, the aforementioned fixing method for securing the filter element 42 also facilitates its replacement. Specifically, when replacing the filter element 42, simply unscrew the second filter element annular clamp 45.

[0108] Specifically, in this embodiment, the filter element 42 is disc-shaped and is made of activated carbon material, hollow fiber membrane or flat sheet membrane.

[0109] Specifically, see Figure 3 and Figure 4 In this embodiment, the lower end of the gas filter cylinder cavity 411 is provided with an internal thread, and the lower cover 43 of the gas filter cylinder is provided with an external thread. The lower cover 43 of the gas filter cylinder is threadedly connected to the lower end of the gas filter cylinder cavity 411 and extends out of the gas filter cylinder cavity 411 by a portion.

[0110] Furthermore, a gas filter assembly mounting hole 23 is provided on the upper cover of the second cylinder 2, and the inner wall of the flow hole 221 is provided with an internal thread that mates with the threaded lower cover 43 of the gas filter cylinder. When installing the gas filter assembly 4, the gas filter assembly 4 is passed through the gas filter assembly mounting hole 23 from top to bottom, and the lower cover 43 of the gas filter cylinder is threaded into place with the flow hole 221. At this time, the lower end of the gas filter cylinder 41 abuts against the upper surface of the separator 22, and the lower cover 43 of the gas filter cylinder also applies pressure to the sealing assembly 3.

[0111] Further, see Figure 3 and Figure 4 In this embodiment, the sealing component 3 includes a sealing elastic element 31 and a sealing cover plate 32.

[0112] The sealing elastic element 31 is arranged vertically, and its lower end is fixedly installed in the lower cavity 212.

[0113] The sealing cover plate 32 is fixedly installed on the upper end of the sealing elastic member 31.

[0114] When the sealing elastic element 31 is in a free state, the sealing cover plate 32 can block the flow hole 221; when the sealing elastic element 31 is under pressure, the sealing cover plate 32 can open the flow hole 221.

[0115] That is, when the sealing assembly 3 is in a free and unpressurized state, the sealing elastic element 31 is in a free state, and the sealing cover plate 32 can block the flow hole 221. When the gas filter assembly 4 applies pressure to the sealing assembly 3, the sealing elastic element 31 is under pressure. At this time, the sealing elastic element 31 undergoes compression deformation, thereby driving the sealing cover plate 32 to move downward, so that the sealing cover plate 32 opens the flow hole 221.

[0116] Furthermore, in this embodiment, the sealing cover plate 32 includes a pressure-receiving part 321 and a sealing part 322.

[0117] The pressure-bearing part 321 is coaxially arranged with the flow hole 221 and its diameter is smaller than that of the flow hole 221.

[0118] The sealing part 322 is coaxially connected to the lower surface of the pressure receiving part 321. The sealing part 322 is coaxially arranged with the flow hole 221 and its diameter is equal to the diameter of the flow hole 221. The gas filter assembly 4 can apply pressure to the pressure receiving part 321 so that the sealing part 322 opens the flow hole 221.

[0119] Specifically, when the gas filter assembly 4 applies pressure to the sealing assembly 3, the sealing elastic element 31 is under pressure. At this time, the sealing elastic element 31 is compressed and deformed, the pressure-bearing part 321 is pressed down and moves downward, and the sealing part 322 also moves downward, so that the flow hole 221 is opened.

[0120] Further, see Figure 3 and Figure 4 In this embodiment, the flow hole 221 includes a small diameter hole 2211 and a large diameter hole 2212.

[0121] The large diameter hole 2212 is coaxially located below the small diameter hole 2211. When the sealing elastic member 31 is in a free state, the pressure-bearing part 321 is movable inside the small diameter hole 2211, and the sealing part 322 seals the large diameter hole 2212.

[0122] That is, in this embodiment, the cross-section of the flow hole 221 is convex, and correspondingly, the sealing cover plate 32 is convex to match the shape of the flow hole 221.

[0123] Preferably, the diameter of the pressure-receiving part 321 is smaller than the diameter of the small-diameter hole 2211. When the gas filter assembly 4 applies pressure to the sealing assembly 3, the sealing elastic member 31 is under pressure. At this time, the sealing elastic member 31 undergoes compression deformation, the pressure-receiving part 321 is pressed down and moves away from the small-diameter hole 2211, and the sealing part 322 also moves down and moves away from the large-diameter hole 2212 at the same time.

[0124] Furthermore, in this embodiment, the sealing component 3 also includes a base 33, which is fixedly disposed in the lower cavity 212, and the lower end of the sealing elastic member 31 is fixedly disposed on the upper surface of the base 33.

[0125] The base 33 is designed to avoid using a sealing elastic element 31 with an excessively large axial dimension, thereby preventing the sealing elastic element 31 from tilting due to its excessive axial dimension.

[0126] Optionally, in this embodiment, the blocking elastic element 31 is a compression spring.

[0127] In this embodiment, the blocking component 3 and the gas filtering component 4 are arranged in a one-to-one correspondence. The number of blocking components 3 can be one or more.

[0128] It is understandable that when there are multiple sealing components 3, the gas filter components 4 corresponding to some of the sealing components 3 can be installed in place; alternatively, they can be left uninstalled without affecting the normal operation of the oil and gas overflow treatment device at the oil test port.

[0129] It is understood that by using the sealing component 3 in this embodiment, even after the gas filter component 4 is removed, the sealing component 3 can block the flow hole 221, which can prevent the gas from being directly discharged into the outside without filtration when the filter element 42 is replaced.

[0130] Furthermore, in this embodiment, the lower end of the second cylinder 2 is provided with an oil discharge port communicating with the lower cavity 212, and an oil discharge valve can be detachably installed at the oil discharge port.

[0131] When there is a large amount of oil accumulated in the lower chamber 212, the oil discharge valve can be opened to discharge the accumulated oil through the oil discharge port.
