Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steam valves, and in particular to an injection-production integrated steam valve. Background Art
[0002] Most of my country's heavy oil reservoirs are basically small-block heavy oil reservoirs. This type of reservoir is a low-grade oil resource with poor crude oil properties. It is difficult to develop, produce, gather and process on the ground. In the capacity construction of heavy oil field development, the injection-production integrated process technology is used for the development of small-block heavy oil fields. It has the advantages of minimum investment and operating costs and good economy. The injection-production integrated pipeline is a pipeline that integrates steam injection and oil output functions from the wellhead to the branch well metering station. The pipeline injects high-pressure steam in the early stage and outputs oil in the reverse direction in the later stage. Different media and opposite flow directions require that the control valves on the pipeline must adapt to the requirements of complex working conditions. In order to meet the needs of heavy oil extraction in oil fields and address the complex working conditions of injection-production pipelines, a high-temperature and high-pressure injection-production steam valve is needed. However, the common injection-production steam valves on the market have large fluid resistance when opening and closing, and during long-term use, the pipeline connection positions are prone to leakage, which is easy to drip onto equipment or the ground. Dust and dirt will enter the thread gaps and merge with the oil. When the valve stem is turned, the dust will follow the valve stem into the steam valve, affecting its service life. In addition, steam will produce liquid, which is more difficult to collect and process, and the steam pressure is too high. Summary of the invention

[0008] The present invention provides an injection-production integrated steam valve, which has the following beneficial effects:
[0009] The steam valve adopts a typical Y-type flow channel design with a 45-degree angle between the axis of the upper and lower valve stems and the edge of the valve body connection end, and has a small fluid resistance when opening and closing. The high-pressure forged steel valve has a shrinking problem due to the characteristics of its processing technology. For example, the DN80 steam valve used for the ¢89×9.5 injection and production integration on site has a minimum flow hole below ¢60 according to the manufacturing process conditions. When the valve medium is high-pressure steam, its flow hole can meet the on-site use requirements. When the oil is discharged in the reverse direction, due to the high viscosity of the crude oil, low pressure and low flow rate, the flow hole after the shrinkage cannot meet the requirements of oil transportation. According to the special requirements of the dual medium, a large-diameter design is adopted to completely solve the problem that the flow hole of the steam valve cannot meet the on-site use requirements due to the shrinkage problem in the later oil discharge. At the same time, on the basis of the original structure, the production process is improved to make the valve direct-flow flow channel almost straight, and the flow resistance and pressure loss are extremely close to those of the gate valve. This improvement makes the oil flow smoother when it flows through the valve in the reverse direction, and completely solves the problem of large pressure loss in the oil outlet pipeline in the later stage of injection and production integration.
[0010] The valve sealing surface adopts tapered sealing, and the sealing surface material is imported alloy material. It is sealed reliably through special process treatment with spray welding equipment imported from Germany. Compared with gate valves and stop valves, the tapered seal of the steam valve has a higher sealing grade. During use, the valve seat and valve disc can achieve mutual grinding effect, which can maximize the sealing performance and meet the control requirements of high-pressure steam medium for a long time in the early stage of the injection and production pipeline. The sealing is reliable (the sealing effect of flat-sealed valves is poor when used in the control of high-temperature and high-pressure steam pipelines).
[0011] In the later stage of oil discharge from the pipeline, if the valve is closed for a long time, a large amount of crude oil will accumulate in the upper chamber. Due to the adhesion of crude oil to the upper chamber of the valve, the torque for reopening and closing is too large, which is not conducive to operation and can easily cause the valve stem to break. The injection-production integrated steam valve effectively solves this problem. The valve disc is equipped with an oil return groove. When the valve is opened, the crude oil is squeezed into the lower chamber through the oil return groove. Combined with the steam valve's proprietary impact handwheel, the operating torque for reopening and closing can be effectively controlled.
[0012] The materials used for the pressure-bearing components of the valves are treated with special equipment and professional processes to resist high temperatures and undergo ultra-low temperature treatment, ensuring that the mechanical properties of the materials meet the requirements of the -50°C conditions in the western high-cold environment and the 374°C requirements of high-temperature and high-pressure media.
[0013] According to the steam dryness required by the operating conditions (①0~80%, ②0~95%), the mineralization of the boiler feed water and the mineralization of the reverse output oil, select the key internal materials (key internals include valve stem, valve disc, sealing surface alloy material, sealing gasket, sealing packing) that meet the operating conditions (-50℃~374℃).
[0014] The mobile component drives the storage tank to the outer bottom of the connector, so that after the connector is connected to the pipeline, when a leak occurs, the leaked object directly enters the storage tank, and the material is easily collected to avoid dripping directly onto the ground or equipment.
[0015] When the upper valve stem is in use, it passes through the inside of the collar component. Since the collar component is made of rubber and fits with the outside of the upper valve stem and is embedded in the threaded gap, when the upper valve stem is installed, the collar component can wipe off the dust to improve the cleaning effect. At the same time, the auxiliary component is located at the bottom of the upper valve stem for use. When the upper valve stem needs to be lubricated, the lubricant can be directly added to the inside of the auxiliary component, which is convenient for adding lubricant.
[0016] The collecting structure is connected to the bottom valve body through a connecting head and a top head structure, so that after steam is generated inside the bottom valve body, the steam enters the collecting structure for collection and storage, and the liquid generated by the steam is conveniently collected. At the same time, when the steam pressure is relatively high, the pressure can enter the inside of the side compartment through the connecting hole, causing the piston plate to move downward under force, so that the downward pressure rod and the force plate structure compress the spring to eliminate the pressure. When the pressure is too high, the piston plate moves excessively to the discharge hole position, allowing the steam to be discharged through the discharge hole to relieve the pressure.

The collar component 204 removes dust from the thread of the upper valve stem 202 to improve the cleaning effect and reduce the entry of dust into the interior. When steam is generated, the liquid generated by the steam enters the interior of the collecting structure 3 through the connecting head 101 and the top head structure 304, so that the liquid is conveniently collected, stored and used. If the pressure is too high, the pressure is transmitted to the interior of the side compartment 302 through the connecting hole, so that the piston plate 308 is stressed. The piston plate 308 drives the lower pressure rod 307 and the force plate structure 306 to move downward. The force plate structure 306 compresses the spring and uses the elasticity of the spring to buffer the pressure. If the pressure is too high, when the piston plate 308 moves to the position of the discharge hole 303, the pressure is discharged through the discharge hole 303 and enters the interior of the guide 301 for pressure relief.
