Description

[Technical Field]

[0001] The present disclosure relates to the technical fields of oil lift devices and gas lift devices, and relates to a golf-type gas lift ball gas lift oil production device, control system and method. [Background technology]

[0002] In terms of the gas lift oil production equipment that is currently commonly used, one method is to mix high-pressure gas injected into the mine from the surface with liquid generated in the oil layer inside the mine, and then use the expansion of the gas to reduce the density of the mixed liquid inside the mine, thereby lifting the oil that has flowed into the mine to the surface.

[0003] Another method is to use high pressure gas to pump gas lift balls down a pipe string to the bottom of the hole, and then use the thrust of the high pressure gas and the gas lift balls to lift the oil to the surface.

[0004] However, because oil reservoirs are usually located deep underground, continuous oil and gas production creates a complex and unstable underground environment, with frequent fluctuations in pressure, temperature, and fluid flow rate at the bottom of the well.

[0005] However, conventional gas lift oil production equipment cannot track changes in the underground environment in real time, making it impossible to timely adjust the pumping speed of the injected high-pressure gas or the throwing frequency of the gas lift ball, which affects the efficiency of gas lift oil production.

[0040] The technical scheme in the embodiments of the present disclosure has at least the following advantages and beneficial effects:

[0041] The present disclosure relates to a golf-type gas lift ball type gas lift oil production apparatus, and a control system and control method for the golf-type gas lift ball type gas lift oil production apparatus. The golf-type gas lift ball type gas lift oil production apparatus includes three parts: a golf-type gas lift ball, a ball storage and throwing device, and a multi-stage starting device.

[0042] The first part, the golf-type gas lift ball, can move smoothly inside the gas lift tee to lift the oil and gas in the tailpipe to the surface, and since the diameter of the ball is smaller than the diameter of the pipe, it can effectively create a treadmill effect.

[0043] Additionally, the hard points or soft burrs formed on the outer sidewall of the golf-type gas lift ball allow for timely removal of wax that has accumulated on the inner wall of the gas lift tee.

[0044] The second part, the ball storage and throwing device, has a simple structure and can effectively store and throw golf-type gas lift balls, resulting in good oil production efficiency from the gas lift balls.

[0045] Furthermore, in the context of the ball storage and throwing device, the slide rail for the gas lift balls is composed of two circular rings and a plurality of metal rods, so that the gas lift balls can move orderly only within the space formed by the metal rods and are not crowded together.

[0046] This structure facilitates the oil being thrown off the surface of the gas lift ball as it moves under the influence of centrifugal force, allowing the gas lift ball to be cleaned before being used again in the hole.

[0047] The third section, the multi-stage starter, includes a multi-stage gas lift valve located in the gas lift tee to achieve staged liquid discharge.

[0048] The treadmill effect of the gas lift ball allows the liquid to be expelled quickly, efficiently and more completely.

[0049] Furthermore, by discharging the liquid in stages, the flow pressure at each stage can be significantly reduced, and the total amplitude of the reduction in flow pressure at the bottom of the hole can be greatly increased, so that the oil and gas at the bottom of the hole can be gradually lifted to the surface under a lower starting pressure.

[0050] The multi-stage starter is applicable to deep-hole gas-lift oil production.

[0051] The device located at the lower end of the multi-stage starting device can use a drilling bullet to move the heating wire and curved plate into the geological crack, thereby heating the thick oil in the geological crack, thereby effectively improving the fluidity of the thick oil and the production efficiency of oil and gas.

[0052] The control method and control system provided for the golf-type gas lift ball gas lift oil production equipment allows downhole data such as temperature, pressure, and speed to be collected in real time and used as a basis for adjusting the throwing frequency of the ball control device on the surface and the gas injection pressure of the high-pressure gas source, thereby improving the efficiency of gas lift oil production. In addition, the control system can operate intelligently and efficiently with the functions of remote data transmission and remote control. [Brief explanation of the drawings]
