Abstract
The utility model relates to a kind of oil well time delay self-expansion type and inserts sealing tool, comprise tool body and time delay self-expanding seal modules, time delay self-expanding seal modules is contained on tool body, time delay self-expanding seal modules is module and the sulfuration different types of rubber seal module composition in module be made up of metallic steel, module upper end is the top vulcanized rubber seal modules that General Purpose Rubber is formed, the self-expanding rubber seal module that middle part is formed for time delay self-expanding rubber, lower end is the bottom vulcanized rubber seal modules that General Purpose Rubber is formed, the module that the metallic steel of tool body and time delay self-expanding seal modules contact surface is formed is provided with sealing ring and lower seal, this instrument has the feature of time lagged swelling, can seal the sealing drum of slight erosion in various degree, wearing and tearing, extends application life of sealing drum, and sealing is reliable, structure is simple, assembling and execute-in-place convenient and easy.
Description
Technical field
The utility model relates to a kind of field produces and inserts sealing tool, and particularly a kind of oilfield time delay self-expansion type inserts sealing tool.
Background technology
Offshore oilfield is producing oil in well, along with increase and the operation frequently of the angle of incidence under sand control pipe, there is wear condition in the down-hole sealing drum of some oil-water wells, the swell increment inserting seal modules due to the routine used at present is less, after entering new insertion sealing under some oil-water wells, insert sealing appearance seepage in various degree, serious layered tubing string occurs testing the underproof situation of envelope, according to statistics, every year because sealing drum lost efficacy, the packer quantity changed at 20 ~ 30, direct losses more than 1,000,000 yuan.Learn after examination is examined, part seal failure causes due to sealing light tube inner surface slight erosion, wearing and tearing.Usually, sealing light cylinder, when slight erosion, wearing and tearing, inserts sealing and namely can lose efficacy.Sealing drum was lost efficacy, usually the way taked salvages sand control packer, the packer more renewed also re-starts sand control, individual well operating cost is more than 4,000,000 yuan, cost is higher, the serious waste resources of production, simultaneously, again sand control treatment can interrupt the normal production of oil-water well, causes the oil well underproduction or well to reduce.
Utility model content
The purpose of this utility model is to provide a kind of oil well time delay self-expansion type and inserts sealing tool, this insertion sealing tool be meet water self-expanding elastomeric material, can prepare by different expansion rate, rubber has the feature of time lagged swelling simultaneously, the sealing drum of slight erosion in various degree, wearing and tearing can be sealed, extend the application life of sealing drum, while it can effectively solve the problem, sealing is reliable, structure simple, assembling and execute-in-place convenient and easy.
A kind of oil well time delay self-expansion type described in the utility model inserts sealing tool, comprise tool body and time delay self-expanding seal modules, time delay self-expanding seal modules is contained on tool body, different types of rubber seal module composition in the time delay self-expanding seal modules module that to be the module that is made up of metallic steel and sulfuration formed in metallic steel, module upper end is the top vulcanized rubber seal modules that General Purpose Rubber is formed, the self-expanding rubber seal module that middle part is formed for time delay self-expanding rubber, lower end is the bottom vulcanized rubber seal modules that General Purpose Rubber is formed, the module that the metallic steel of tool body and time delay self-expanding seal modules contact surface is formed is provided with sealing ring and lower seal.
During operation, the two ends of time delay self-expansion type insertion sealing tool are connected with tubing string and kit respectively, time delay self-expansion type arrives in the sealing drum of predetermined distance under inserting sealing tool, the different types of rubber seal module of sulfuration in module, after meeting water, in official hour, own vol expands, owing to having time lagged swelling feature, the construction of face length time can not impact over the ground.
Time delay self-expansion type described in the utility model inserts sealing tool tool and has the following advantages:
1. the hydro-expansive rubber inserted on sealing tool can select the rubber of different expansion rate, realize sealing drum slight erosion in various degree, wearing and tearing and cause seal failure when, still can play sealing function, thus not need to adopt replacing to insert sealing drum just energy layered seal.
2. self-expanding rubber has delay function, can not meet water and expand at once, can not impact construction in the short time of ground.
3. sealing structure can extend well workover interval time, reduces workman's workload, extends the normal production cycles of producing well, to stable yields, the volume increase of producing well, has very large facilitation.
Accompanying drawing explanation
Fig. 1 oil well time delay self-expansion type inserts sealing tool structural representation.
In figure:
1 tool body, 2 top vulcanized rubber seal modules, sealing ring on 3,4, time delay self-expanding seal modules, 5 self-expanding rubber seal modules, 6 lower seal, 7 bottom vulcanized rubber seal modules
Detailed description of the invention
A kind of oil well time delay self-expansion type described in the utility model inserts sealing tool, comprise tool body 1 and time delay self-expanding seal modules 4, time delay self-expanding seal modules 4 is contained on tool body 1, time delay self-expanding seal modules 4 is module and the sulfuration different types of rubber seal module compositions in module be made up of metallic steel, module upper end is the top vulcanized rubber seal modules 2 that General Purpose Rubber is formed, the self-expanding rubber seal module 5 that middle part is formed for time delay self-expanding rubber, lower end is the bottom vulcanized rubber seal modules 7 that General Purpose Rubber is formed, the module that the metallic steel of tool body 1 and time delay self-expanding seal modules 4 contact surface is formed is provided with sealing ring 3 and lower seal 6.
Claims (1)
1. an oil well time delay self-expansion type inserts sealing tool, comprise tool body and time delay self-expanding seal modules, it is characterized in that: time delay self-expanding seal modules is contained on tool body, time delay self-expanding seal modules is module and the sulfuration different types of rubber seal module composition in module be made up of metallic steel, module upper end is the top vulcanized rubber seal modules that General Purpose Rubber is formed, the self-expanding rubber seal module that middle part is formed for time delay self-expanding rubber, lower end is the bottom vulcanized rubber seal modules that General Purpose Rubber is formed, the module that the metallic steel of tool body and time delay self-expanding seal modules contact surface is formed is provided with sealing ring and lower seal.
