Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the oil-gas separation tank for oil well yield detection comprises a tank body 1, wherein the tank body 1 is of an inclined cylindrical structure, a base 2 is arranged at the bottom of the cylindrical structure, supporting legs 3 are arranged on the side portion of the cylindrical structure, an input pipe 11 is arranged on the upper portion of one side of the tank body 1, a liquid phase output pipe 12 is arranged on the lower portion of the tank body 1, a gas phase output pipe 13 is arranged on the top of the tank body 1, an anti-overflow cover 4 in an inverted funnel-shaped structure is arranged in an inner cavity of the tank body 1 on the lower portion of the gas phase output pipe 13, and a blocking ball 5 is arranged on the lower side of the anti-overflow cover 4; the drum 6 is arranged in the tank body 1 at the lower part of the input pipe 11, the drum 6 comprises a drum with two ends sealed and a middle shaft, the middle shaft is arranged in the center of the drum through a bearing, two ends of the middle shaft are fixedly connected to the inner wall of the tank body 1, and a plurality of round holes are uniformly distributed on the peripheral wall of the drum. The lower part of the roller 6 is provided with a sieve plate 7, the sieve plate 7 is formed by arranging a plurality of small holes on a corrugated plate, and two ends of the sieve plate 7 are fixedly connected on the inner wall of the tank body 1. The part of the input pipe 11 in the tank body 1 is provided with a rectangular gap facing the roller 6. A hanging rod is arranged on the plugging ball 5, the upper end of the hanging rod penetrates to the upper side of the middle part of the bracket arranged in the gas phase output pipe 13 and is in threaded connection with a nut; the support is the bar shaped plate that the centre is equipped with the round hole, and this bar shaped plate both ends are fixed on the inner wall of gaseous phase output tube 13, and blocking ball 5 just so utilizes the jib to be hung on the support, and the nut is used for preventing the jib from breaking away from the support.
When the device is used, the device is fixed by the base 2 and the supporting legs 3, the input pipeline 11 of the device is connected with the output liquid outlet of a single well of an oil field through a quick connector, and the liquid phase output pipe 12 and the gas phase output pipe 13 are respectively connected with a metering system through quick connectors.
The working principle is as follows: the output liquid of the single well enters the tank body 1 through the input pipeline 11, falls through the rectangular opening, passes through the roller 6 and the sieve plate 7 and is output through the liquid phase output pipe 12; in the process, the roller 6 rotates under the action of gravity of the produced liquid falling, the produced liquid can flow into and out of the round hole of the roller 6, so that gas-liquid separation is facilitated, the produced liquid falling from the roller 6 immediately falls onto the obliquely arranged sieve plate 7, and then falls through the sieve plate 7 and the small hole formed in the upper part of the sieve plate, and the gas-liquid separation is enhanced again. When a certain reason causes too much liquid phase in the tank body 1, the liquid level of the liquid phase rises to the blocking ball 5, the blocking ball 5 floats up along with the liquid phase and blocks the lower end of the gas phase output pipe 13 in the middle of the anti-overflow cover 4, the phenomenon that the liquid phase overflows through the gas phase output pipe 13 is effectively prevented, after the liquid level of the liquid phase falls, the blocking ball 5 falls along with the liquid phase until the liquid phase leaves the lower end of the gas phase output pipe 13, the liquid level of the liquid phase continues to fall, the suspender does not fall under the action of the nut at the top end of the suspender, the blocking ball 5 is in a suspension state, and the separated gas phase continues to be output through the gas phase output pipe 13.
The invention has reasonable design, simple structure and easy manufacture, adopts the design of the roller, the sieve plate, the anti-overflow cover and the plugging ball, can effectively solve the problems of incomplete gas-liquid separation and overflow of liquid phase through a gas phase output pipe when measuring an oil well, brings convenience to the production dynamic analysis of the oil well, and can meet the requirement of oil reservoir evaluation.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
