TECHNICAL FIELD

[0001] The present application relates to the technical field of oil and gas exploitation equipment, in particular to an oil and gas field stimulation device and method. BACKGROUND

[0002] In the oil and gas field stimulation technology, the stimulation agent is a functional chemical agent used with the stimulation device, and the core function is to optimize the reservoir environment, reduce the mining resistance, and improve the oil and gas flowability through chemical action, to form a "chemical + physical" synergistic effect with the physical stimulation, which is a key auxiliary material for the stimulation of complex reservoirs.

[0003] In the oil and gas field stimulation operation, the mixed agent before injection needs to be stirred, and the core is a "multi-component complex system", that is, a single agent cannot meet the functional requirements, and two or more chemical agents need to be mixed in a specific proportion to form a synergistic formula system. The mixing effect of such agent directly affects the stimulation efficiency, and needs to be uniformly dispersed through stirring to avoid stratification, precipitation or local high concentration leading to reservoir damage.

[0004] For example, the fracturing fluid complex system needs to realize multiple functions such as "sand carrying, fracture forming, swelling prevention, and gel breaking" in the fracturing operation, and the base fluid and various additives must be mixed uniformly through stirring. The typical combination of the fracturing fluid is: base fluid, thickening agent, crosslinking agent, anti-swelling agent and gel breaker. When stirring, the thickening agent needs to be first added to the base fluid and stirred uniformly, then the crosslinking agent is added, and the anti-swelling agent and gel breaker are added at the same time, and the third stirring is uniform. The existing stirring device needs a long time for full stirring, and the three full stirrings lead to a long configuration process of the fracturing fluid and low configuration efficiency of the stimulation agent, so a new technical solution is needed to solve the above technical problems.

[0024] A second aspect of this application provides a method for enhancing oil and gas well production, using the aforementioned oil and gas well production enhancement device, comprising the following steps: S1.

[0025] The working principle and beneficial effects of this application are as follows: 1.

At the same time, the planetary gears revolve around the sun gear and also rotate on their own axis. The planetary gears drive the injection pipe to revolve around the stirring device and also rotate around the injection pipe's own axis. This makes the liquid medicine poured into the injection pipe more evenly distributed in the liquid, and achieves the simultaneous rotation and rotation of the stirring device and the liquid medicine in the injection pipe.

[0027] 3. By setting up a stirring device and several spraying rods on the filling pipe, the liquid medicine is sprayed using the spraying pipes. At the same time, when the filling pipe rotates, it drives the spraying pipes to rotate around the axis of the filling pipe, making the spraying of the liquid medicine more uniform. At the same time, the filling pipe and spraying pipes are used to stir the liquid medicine and liquid, realizing multi-core stirring and mixing of the filling pipe and stirring device, and accelerating the full mixing of the liquid medicine and liquid.

The liquid in the liquid source is used to clean the liquid medicine in the inlet pipe 7, the main delivery pipe 6, the delivery branch pipe 61, the filling pipe 4, and the spraying pipe 41, ensuring that the added dosage of medicine completely enters the mixing tank 1 and does not cause the medicine added twice to mix.

[0036] like Figures 4-5 As shown, the bottom end of the lid 2 is provided with a sliding groove 22 for allowing the planetary gear 52 to drive the filling tube 4 to slide. A rotating bar 8 is provided in the sliding groove 22 and is slidably connected to the sliding groove 22.

It is important to note that the stirring blades on the stirring rods 32 and the stirring blades on the spray pipes 41 should not interfere with each other when rotating simultaneously.

[0039] The basic principle of this embodiment is as follows: When using the production enhancement device, the liquid medicine is first pumped into the inlet pipe 7 through the liquid medicine pipe 71. The liquid medicine is then transported to the main delivery pipe 6 through the inlet pipe 7, and then into the delivery branch pipe 61 through the main delivery pipe 6.

At the same time, the drive component 9 is activated to drive the drive gear 91 to rotate. The drive gear 91 drives the gear ring 53 to rotate. The rotation of the gear ring 53 drives the planetary gear 52 and the sun gear 51 to rotate synchronously. The planetary gear 52 revolves around the sun gear 51 while rotating on its own axis, so that the rotation of the planetary gear 52 drives the filling pipe... 4. The injection pipe 4 rotates, driving the spray pipe 41 to rotate around its own axis. At the same time, the planetary gear 52 revolves, driving the injection pipe 4 to revolve around the stirring shaft 31.
