Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oilfield machine well production, and particularly relates to an intelligent type bailing oil extraction equipment and a new energy bailing oil extraction system for oilfields. BACKGROUND

[0002] At present, the beam-type pumping unit is the main ground equipment for oil exploitation and is the earliest and most commonly used pumping unit. The working principle of the beam-type pumping unit is that the motor drives a crank rocker mechanism to convert the rotary motion of the output shaft of a reduction box into the reciprocating motion of a beam horsehead through a belt pulley and a reduction box, so as to drive the sucker rod column to make linear reciprocating motion, and then the motion is transmitted to the plunger of the downhole oil pump through the sucker rod, so that the plunger works to extract oil.

[0003] The beam-type pumping unit is one of the largest energy-consuming equipment in the petroleum industry. According to statistics, about two-thirds of the energy consumption in oilfield energy consumption is electric energy, and the electric energy consumed by the beam-type pumping unit accounts for about 40% of the total electric energy consumption. According to incomplete statistics, the number of pumping units in China exceeds 600,000, the total installed capacity of motors is more than 3,500 MW, and the annual electricity consumption exceeds 10 billion degrees. At present, the operation efficiency of the pumping unit is still relatively low, and the average operation efficiency in China is only 25.96%, while the average level abroad is 30.05%. If the advanced energy efficiency level abroad can be reached, several billion degrees of electricity can be saved every year. Therefore, there is a huge energy-saving potential for pumping unit wells.

[0004] Although the beam-type pumping unit is still a commonly used device in oilfield mechanical oil extraction, it is usually used in cooperation with a sucker rod and an oil pump. At present, various types of pumping units have different characteristics and functions to meet the needs of different working conditions, and there are also energy-saving pumping units. However, the existing pumping units can generally only be used for ordinary oil wells (generally about 300 meters), and as society continues to progress, a large amount of oil resources is still needed. The exploitation of deep wells (generally more than 5,000 meters) is very difficult, and a large amount of oil is contained in ordinary oil wells below 1,500 meters to 2,500 meters. However, the existing pumping wells are generally not suitable for such deep wells, especially for the exploitation of oil containing a large amount of fine sand (micron type fine sand), which cannot meet the use requirements. Therefore, it is necessary to improve the existing pumping unit and oil extraction system. SUMMARY

At this time, the pinion 681 is loosened by rotating to the left and then starts to run, and the adjusting nut sleeve 652 is adjusted once every several days according to the actual situation. It is to be explained that the oil pumping rod 61 is a flexible oil pumping rod.

[0064] In the application, the drum pulley sealing device 2, the sealing rod taking device and the sealing rod packing assembly 6 are all fully sealed, which greatly reduces pollution and also reduces the occurrence of personal safety accidents.

[0065] As Figure 14As shown, this invention also provides a new energy-based oil extraction and production system for oil fields, including an intelligent oil extraction and production device 100 as described above, a power generation unit 200, and a thermal insulation and storage device 300. The power generation unit 200 is connected to the intelligent oil extraction and production device as described above, and the intelligent oil extraction and production device as described above is connected to the thermal insulation and storage device 300 via an oil pipeline. Further, the power generation unit 200 includes any combination of one or more of the following: a natural gas power generation system 201, a solar power generation system 202, or a wind power generation system 203 (especially a vertical axis wind power generation system; the wind power generation system 203 has a stroke of 1-50m, a rated load at the suspension point of 100kN, a stroke rate of 1-10 / h, a motor power of 22kW-30kW, and a conventional pumping unit stroke of 1-5m; and uses a load sensor 251 to understand downhole conditions and provide technical parameters to improve oil recovery rate). The wind power generation system 203 is preferably a micro-wind magnetic levitation wind power generation system. In the absence of power in the oilfield, the wind power generation system 203 can independently generate electricity for oil extraction from each well, and can also power 4 to 5 intelligent oil extraction and retrieval devices 100. Because the natural gas power generation system 201, solar power generation system 202, or wind power generation system 203 operates in a fully enclosed manner, it achieves zero-emission green oil extraction. Those skilled in the art understand that the natural gas power generation system 201, solar power generation system 202, or wind power generation system 203 provides power to components such as the drum pulley sealing device 2, and therefore knows that it is connected by electrical wires. Figure 14 It is not marked in the text. For example... Figure 15 As shown, it also includes a main drive mechanism 204, which is connected to the drum pulley sealing device 2 in the intelligent oil extraction equipment 100 described above, thereby driving the drum pulley sealing device 2 to move. Furthermore, the insulated storage device 300 includes at least one oil storage tank, which is interconnected and has an insulated effect, further facilitating oil preservation. The total volume of the insulated storage device 300 is 120 cubic meters of oil. It should be noted that it also includes an insulated transport vehicle 400, whose outlet connects to the insulated storage device 300. The insulated transport vehicle 400 can carry 18 cubic meters of oil, creating favorable conditions for storage and transportation.

[0066] like Figure 14 , Figure 15 and Figure 16As shown, the wind power generation system 203 is a micro-wind magnetic levitation wind power generation system, wherein the natural gas power generation system 201 and the micro-wind magnetic levitation wind power generation system are installed on the intelligent oil extraction equipment 100 as described above, and the solar power generation system 202 is separated from the intelligent oil extraction equipment 100 as described above. Since those skilled in the art know that the natural gas power generation system 201 or the solar power generation system 202 or the wind power generation system 203 provides electric energy for the components such as the drum and pulley sealing device 2, it is known that the connection is by wire, and here it is not repeated.

[0067] In the present application, the main transmission mechanism 204 is controlled by the electric control device 3 in the intelligent oil extraction equipment 100, and then the main transmission mechanism 204 drives the drum and pulley sealing device 2 to operate, the drum and pulley sealing device 2 drives the sucker rod assembly 5 to move, the sucker rod assembly 5 pulls the production device 7 (sand setting and sand prevention production device 71 or casing exhaust device 72) to perform reciprocating linear motion, so that the reciprocating linear motion of the production device 7 (sand setting and sand prevention production device 71 or casing exhaust device 72) performs the work of producing oil. The electric control device 3 controls the drum and pulley sealing device 2, the drum and pulley sealing device 2 drives the sucker rod assembly 5 to move, the sucker rod assembly 5 pulls the casing production device to perform reciprocating linear motion, when the plunger in the plunger part 72181 moves downward, the plunger traveling valve opens the liquid inlet oil tail pipe 7219, when the plunger in the plunger part 72181 moves upward, the plunger traveling valve closes, at this time the liquid enters the industrial pipeline to complete one oil production work.

[0068] The present application solves the problems of environmental pollution and personal safety, and also solves the problems of pump sticking and fixed valve failure, and improves the stroke to 50m, thereby improving the oil production rate and reducing the oil production cost (the total cost can be reduced by more than 30%), and independent power generation solves the problem of no power supply in oil field (self-generating power in the absence of power supply and can drive four or five oil pumps to work), wherein the casing exhaust device 72 saves the oil pipe and simplifies the oil production process and reduces the oil production cost.

[0069] The electric control device 3 is a control cabinet, wherein the control cabinet is provided with a control screen and control buttons, and the control cabinet is remotely controlled through a wireless module, so that the remote controller is used to start, stop, adjust the stroke and frequency, and the control screen is provided with a display screen, the display screen comprises a client, and the client can realize real-time data display, yield calculation, power diagram analysis, system optimization, chart display, historical data query, report system, user management and a plurality of functions, and can support user customization and development. The electric control device 3 realizes safe, intelligent and stable operation of the equipment by monitoring the real-time data and the running state of the equipment, and realizes measurement and metering of the data. The electric control device 3 uses a plurality of wireless network resources, transmits the collected field data to the monitoring center through a data terminal, and processes, stores and provides corresponding query, statistics and report functions. The monitoring center can send information to the data terminal to set the monitoring terminal configuration information or control command, update the real-time data of the data terminal, so that the production and management personnel can timely control and master the production dynamics, realize automation of the whole production process, and can statistically analyze and optimize the obtained real-time data, thereby providing an important basis for ensuring normal operation of the production equipment and reducing production cost.
