Wellhead safety three-valve control integrated module

Abstract

The invention discloses a wellhead safety three-valve control integrated module. The wellhead safety three-valve control integrated module comprises a first valve block, a second valve block, a thirdvalve block, a fourth valve block and a fifth valve block which are adjacently connected together, the contact surfaces of the adjacent surfaces of the first valve block, the second valve block, the third valve block, the fourth valve block and the fifth valve block are consistent in size, through holes are formed in the four corners of the first valve block, the second valve block, the third valve block and the fourth valve block correspondingly, threaded holes are formed in the four corners of the fifth valve block, and four bolts penetrate through the through holes in the first valve block,the second valve block, the third valve block and the fourth valve block to be connected to the threaded holes to fix the first valve block, the second valve block, the third valve block, the fourthvalve block and the fifth valve block. According to the wellhead safety three-valve control integrated module provided by the invention, a plurality of valves are integrated, the space is effectivelyutilized, the structure is simple and reasonable, maintenance is convenient, control is convenient, and the wellhead safety three-valve control integrated module is especially suitable for controllingdownhole safety valves, ground wing valves and ground main valves in natural gas well and oil production well control systems.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas exploitation, in particular to a wellhead safety three-valve control integrated module. Background technique [0002] Due to the rapid development of society, the demand for energy continues to increase. Now more and more wellheads such as oil wells and natural gas wells are being developed, and the wellhead pressure is getting higher and higher. The safety of wellhead production is becoming more and more important in the process of oil and gas recovery. The wellhead is generally in the field, which is difficult to manage and the management cost is high. With the continuous improvement of technology, various valves and pipelines are becoming more and more complicated. Its safety, reliability and ease of maintenance are very important. [0003] At present, the hydraulic control circuit of the ground wing valve, ground main valve and downhole safety valve of the traditional domesti...

Problems solved by technology

The wellhead is generally in the field, which is difficult to manage and the management cost is high. With the continuous improvement of technology, various valves and pipelines are becoming more and more complicated. Its safety, reliability and ease of maintenance are very important.

[0003] At present, the hydraulic control circuit of the ground wing valve, ground main valve and downhole safety valve of the traditional domestic wellhead safety control system is spliced ​​by single components, pipes and joints. The disadvantages of this method are: 1. The components are scattered and the operation is not easy. Convenient, and easy to cause misoperation; 2. There are many contacts between components, resulting in many system leakage points; 3. The connection is complicated, which affects system maintenance; 4. It takes up a lot of space and increases the overall size of the equipment; the above problems are serious Affect the security and reliability of the system
