Description
Technical field
This utility model be specifically related to a kind of seesaw type sliding sleeve opener and etc. diameter through sleeve sliding sleeve.
Background technology
The completion of shale gas horizontal well mainly uses casing cementing, multistage open hole packer to add sliding sleeve both modes at present.
Multistage open hole packer adds the completion mode of pitching classification sliding sleeve can save casing cementing expense, reservoir reconstruction construction
Speed is fast, but this completion mode is on the one hand limited due to the progression of segmentation, and the latus rectum of toe well section is limited, limits reservoir
The scale of transformation；On the other hand, when sliding sleeve fault can not be opened, corresponding well section can only be given up, the well stayed after job execution
Cylinder space is the most limited, substantially cannot follow up；Meanwhile, owing to the sealing effectiveness of packers at different levels is difficult to detect,
So long term seal cannot ensure.
For casing cementing completion, pumping bridging plug can be used to carry out segmentation reservoir reconstruction, segmentation progression with perforation combined tech
Do not limit, it is possible to achieve massive hydraulic fracture is transformed, and can leave complete cased borehole space, it is simple to after taking after operation
Continuous measure operation, but this mode speed of application is relatively slow, and duty cycle is long；Casing packer is entered under after can also using perforation
Add sliding sleeve tubing string and carry out segmentation transformation, but segmentation sum of series transformation scale is smaller, when using sand fracturing mode, it is difficult to
Trip out working string.
For the defect of above both completion mode, external large-scale application sliding sleeve of bushing staged fracturing technology, state in recent years
The most also there is unit to introduce application TAP etc. and without differential sliding sleeve technology and carried out production domesticization research, also have unit to ball-throwing type simultaneously
Sliding sleeve of bushing and intelligence sliding sleeve technology are studied, but other research unit or petroleum Engineering Technological Service company at present
The sliding sleeve of exploitation, uses the structure design throwing in opener, all can not realize batch level and open and pit shaft drifting before and after pressure break
Constant.And the reliability of opener is relatively big on the impact of wellbore environment, thus results in reliability the highest, so needing
The latus rectum such as reliability, realization, the aspect such as simple to operate carry out tackling key problem research.
