Description

Technical Field

[0001] The invention relates to the technical field of oil production, in particular to special equipment for oil drilling. Background Art

[0002] The oil well exploitation process mainly includes the steps of exploration, drilling, oil production and lifting. After the drilling is completed, oil production and lifting are carried out. Oil production is to install casing at the bottom of the well and inject oil well cement to maintain the well wall and seal the oil, gas and water layers. Then use a perforating gun to shoot open the oil layer to form a channel, and use the oil pipe to raise the oil from the bottom of the well to the wellhead. Lifting is to transport the oil from the bottom of the well to the ground through a suitable inducing flow method. In the process of oil extraction, natural gas will be extracted together with crude oil. For this reason, oil and natural gas are usually separated after extraction to facilitate the subsequent processing of oil and natural gas, so as to facilitate subsequent use.

[0003] The disclosure is of publication number CN117536603B, which discloses a purification device and method for using foam drainage based on natural gas exploitation in a gas field. The problem raised in the background technology is that the medium flowing in the gas production pipe includes natural gas and accumulated water containing foam. The long-term circulation of the two together will reduce the calorific value of the natural gas and reduce the efficiency of the fuel. At the same time, there is also a certain amount of foam in the accumulated water after the separation of gas and liquid, which increases the difficulty of post-treatment of the accumulated water.

[0004] Based on the existing technology, there are the following problems:

[0005] Existing devices for separating oil and natural gas in oil wells usually use centrifugal separation methods, but since a large amount of impurities are mixed in the oil and it is not convenient to adjust according to the amount of oil and natural gas extracted, the separation efficiency is easily affected, thereby affecting the subsequent processing of oil and natural gas. Although the above application document is convenient for separating the liquid in the natural gas, it does not block the liquid, resulting in the discharge of natural gas and liquid together, affecting the separation effect, and there are certain shortcomings. In order to solve the above problems, a special equipment for oil drilling is proposed. Summary of the invention

[0055] The first mounting seat 51 is fixedly arranged on the top inner wall of the tank body 4, and the bottom of the first mounting seat 51 is movably provided with a first baffle 592 and a connecting plate 591 which are symmetrically arranged with respect to the center point of the first mounting seat 51, and the first baffle 592 and the connecting plate 591 move in a trajectory approaching or moving away from each other, and a second baffle 59 is rotatably provided on the inner side of the connecting plate 591, and a gap is left between the bottom of the second baffle 59 and the bottom inner wall of the tank body 4, and the side wall diameter of the second baffle 59 is smaller than the inner wall diameter of the tank body 4, so that the oil can be blocked by the second baffle 59 while the natural gas can be transported along the gap between the second baffle 59 and the inner wall of the tank body 4.

[0056] The longitudinal section of the second baffle 59 is circular, so as to be easily rotated on the inner wall of the tank body 4, and a space is reserved between the second baffle 59 and the first baffle 592 for the second baffle 59 to turn over, so as to adjust the blocking area of ​​the second baffle 59 for the oil;

[0057] The connecting plate 591 and the first baffle plate 592 are both designed to be semi-annular, so that the first baffle plate 592 blocks the gap between the upper end of the side wall of the second baffle plate 59 and the top inner wall of the tank body 4 .

[0058] In a specific implementation, after the oil enters the tank body 4 through the first conduit 2, it is sprayed on the side walls of the first baffle 592 and the second baffle 59, so that the oil is blocked by the first baffle 592 and the second baffle 59, and the gas such as natural gas in the oil flows to the right side of the inner wall of the tank body 4 through the gap between the diameter of the second baffle 59 and the inner wall of the tank body 4, while the blocked oil and impurities flow to the bottom inner wall of the tank body 4 and flow into the second auxiliary mechanism 9, so as to separate the oil and gas, and the oil liquid in the oil is blocked by the first baffle 592 and the second baffle 59, so as to separate the oil and gas by the difference in the fluidity of gas and liquid, so as to quickly separate a large amount of oil and natural gas, thereby improving the efficiency of subsequent processing of oil and natural gas;

[0059] The first baffle 592 blocks the upper end of the side wall of the second baffle 59, reducing the amount of oil in the petroleum directly sprayed to the right side of the inner wall of the tank body 4, thereby improving the effect of separating oil and gas, and allowing the natural gas to flow to the right side of the tank body 4 along the gap between the first baffle 592, the second baffle 59 and the inner wall of the tank body 4.

[0060] See also Figure 6 , Figure 7 and Figure 8 , the first auxiliary mechanism 5 also includes:

[0061] The first slide groove 55 is provided at the bottom of the first mounting seat 51. The first slide blocks are arranged symmetrically with respect to the center point of the first mounting seat 51. The bottoms of the first slide blocks are fixedly connected to the tops of the connecting plate 591 and the first baffle plate 592 respectively.

[0062] The first threaded rod 593 is rotatably disposed on the side wall of the first mounting seat 51 and extends into the first slide groove 55. The side wall of one end of the first threaded rod 593 located in the first slide groove 55 is threadedly connected to the first slider, and the first threaded rod 593 is designed as a bidirectional screw to drive the connecting plate 591 and the first baffle plate 592 to move closer to or away from each other.

[0063] Guide grooves are provided at the bottom of the first mounting seat 51 and on both sides of the first slide groove 55. Guide blocks are placed inside the guide grooves and are respectively fixedly connected to the connecting plate 591 and the first baffle plate 592 to limit the movement of the first baffle plate 592 and the connecting plate 591. The first mounting seat 51 is designed in an arc shape to fit the top inner wall of the tank body 4. The first auxiliary mechanism 5 also includes:

[0064] The first servo motor 56 is fixed on the top of the tank body 4. The output shaft of the first servo motor 56 is fixed with a first rotating shaft extending into the tank body 4 through a coupling. The side wall of one end of the first rotating shaft located in the tank body 4 is provided with a transmission mechanism 58 for transmission connection with the first threaded rod 593, and a sealing design is provided between the first rotating shaft and the tank body 4.

[0065] The first auxiliary mechanism 5 also includes:

[0066] The movable seat 52 is symmetrically arranged on the back inner wall of the tank body 4. A second slide groove 53 is opened on the side where the movable seats 52 are close to each other. A second slider is placed inside the second slide groove 53. A second servo motor 57 is fixedly arranged on the side where the second slider is close to each other. The output shaft of the second servo motor 57 is fixedly provided with a second rotating shaft through a coupling. The two ends of the side wall of the second rotating shaft are respectively rotatably connected to the two sides of the side wall of the connecting plate 591, and the middle end of the side wall of the second rotating shaft is fixedly connected to the second baffle 59, so that the second servo motor 57 drives the second baffle 59 to rotate without affecting the adjustment of the position of the second baffle 59. The back inner wall of the tank body 4 is designed to protrude outward, so that the back inner wall of the tank body 4 forms an installation cavity 54 for installing the movable seat 52, and the movable seat 52 is symmetrically arranged around the center point of the installation cavity 54.

[0067] In specific implementation, the amount of oil and natural gas in the delivery pipe 1 is monitored by the flow sensor on the outer wall of the delivery pipe 1, so as to adjust the distance between the first baffle 592 and the second baffle 59 and the degree of flipping of the second baffle 59 according to the amount of oil and natural gas, thereby adjusting the blocking effect of oil and the size of the natural gas flow channel, so as to facilitate adjustment according to actual conditions;

[0068] When there is more oil and less natural gas, the second servo motor 57 is started, and the output shaft of the second servo motor 57 drives the second shaft to rotate through the coupling, and the second shaft drives the second baffle 59 to rotate, so that the second baffle 59 is in a vertical state, thereby increasing the blocking area of ​​the second baffle 59 for oil, and further improving the blocking effect of oil. When there is less oil and more natural gas, the second servo motor 57 drives the second baffle 59 to rotate, so that the top of the second baffle 59 is close to the first baffle 592, so that the second baffle 59 is tilted to reduce the area of ​​oil blocking, and at the same time, increase the gap between the second baffle 59 and the inner wall of the tank body 4, so as to facilitate the rapid circulation of natural gas, so that it can be adjusted according to the actual amount of oil and natural gas;

[0069] In order to improve the effect of adjustment, the first rotating shaft is driven by the coupling of the first servo motor 56, and the first rotating shaft drives the first threaded rod 593 to rotate through the transmission mechanism 58, so that the first baffle 592 and the second baffle 59 are close to or away from each other along the first slide groove 55, so as to adjust the spacing between the first baffle 592 and the second baffle 59, so as to adjust the effect of blocking oil and natural gas between the first baffle 592 and the second baffle 59. When the first baffle 592 and the second baffle 59 are far apart, the gap between the first baffle 592 and the second baffle 59 is large, so that the effect of blocking natural gas is low, and vice versa, the blocking effect is high, so as to improve the effect of adjustment, the transmission mechanism 58 includes transmission gears fixedly sleeved on the first threaded rod 593 and the side wall of the first rotating shaft respectively and meshing with each other, so that the first servo motor 56 drives the first threaded rod 593 to rotate;

[0070] By making the connecting plate 591 rotatably connected with the second baffle 59, it is convenient for the first threaded rod 593 to drive the connecting plate 591 and the second baffle 59 to move without affecting the second servo motor 57 driving the second baffle 59 to rotate. Since the second servo motor 57 is arranged in the tank body 4, a protective cover is fixedly provided on the outer wall of the second servo motor 57 to avoid affecting the use of the second servo motor 57.

[0071] The oil is blocked by the first baffle 592 and the second baffle 59, and at the same time, the natural gas is allowed to flow through the gap between the second baffle 59 and the tank body 4, thereby facilitating the diversion of oil and natural gas and reducing the amount of subsequent intermixing of natural gas and oil for subsequent processing and use.

[0072] See also Figure 2 and Figure 3 A guide plate 10 is fixedly provided on the bottom inner wall of the tank body 4 and located on the right side of the second baffle 59, and a guide groove 101 is opened on the top of the guide plate 10.

[0073] In the specific implementation, the guide plate 10 is provided to block the oil flowing to the inner wall of the bottom of the tank body 4, so as to prevent the oil from flowing to the right side of the inner wall of the tank body 4, thereby reducing the amount of oil entering the second conduit 8, and the guide plate 10 and the guide groove 101 are used to guide the oil, so that the oil can enter the second auxiliary mechanism 9, and the impurities mixed in the oil are deposited in the guide groove 101. Since the guide groove 101 is designed to be inclined, it is convenient for the impurities to flow into the second auxiliary mechanism 9;

[0074] The baffle plate 102 facilitates the blocking of the oil, and the guide groove 101 facilitates the oil to enter the second auxiliary mechanism 9.

The bottom inner wall of the second shell 991 is fixed with a fifth tube body 99 extending into the first shell 93, and one end of the fifth tube body 99 located in the first shell 93 is located at the bottom of the first filter disc 94. The second filter disc 993 is fixedly sleeved on the upper end of the inner wall of the fifth tube body 99. The left side of the second shell 991 is fixed with a sixth tube body 992 which is connected to the second shell 991.

[0078] In a specific implementation, the blocked oil enters the first housing 93 through the first pipe body 91 and flows downward, so that the auxiliary component 92 blocks the downwardly flowing oil and disperses the oil, thereby preventing the oil from flowing downward with a large inertia, reducing the probability of solid impurities in the oil clogging the first filter disc 94, thereby facilitating the separation of impurities in the oil, so as to facilitate the subsequent processing of the oil. The oil separated by the first filter disc 94 enters the second pipe body 98 to be transported to the next processing station, and the oil can be transported to the guide groove 101 through the third pipe body 97 and the fourth pipe body 95 through the third pump body 96, so as to facilitate the flushing of impurities accumulated in the guide groove 101, so that it flows into the second auxiliary mechanism 9, so as to facilitate the subsequent processing of the oil. It is convenient to process impurities in the oil and avoid the accumulation of a lot of impurities in the guide groove 101 to affect the amount of oil blocked. When the oil is transported to the guide groove 101, the valve on the outer wall of the second tube body 98 is closed, and the valve on the outer wall of the third tube body 97 is opened to facilitate the oil to flow into the third tube body 97. The separated impurities enter the second shell 991 after being filtered by the first filter disc 94 and are deposited in the second shell 991. It is convenient to process the impurities in the second shell 991 through the sixth tube body 992, which is convenient for long-term use. The oil entering the second shell 991 is discharged into the second shell 991 again through the fifth tube body 99 and discharged to the bottom of the first filter disc 94 to avoid a lot of oil being retained in the second shell 991.

[0079] The first filter disc 94 is tilted to facilitate the entry of impurities into the second shell 991 , and the inner wall diameter of the first shell 93 is larger than the inner wall diameter of the first tube 91 to reduce the flow rate of oil in the first shell 93 .
