Description
Technical field
The utility model is related to oil reservoir production technique field more particularly to a kind of well cementation fracturing technology tubing strings.
Background technology
Fracturing technique can greatly increase the recoverable reserves of oil gas, make the Low Permeability Oil/gas being worth originally without commercial mining
It hides, becomes the major oil and gas field with suitable commercial reserves and exploitation scale.Hydraulic fracturing, which is increasingly becoming, determines that low permeability oil field is opened
The leading factor of originating party case is in advantageous orientation by hydraulic fracture and determines well when studying and defining LOW PERMEABILITY OILFIELD DEVELOPMENT scheme
Orientation is arranged, by researching and analysing the influence of different well patterns, cloth well density and crack matching to every development index, to improve oil field
Whole development effect and economic benefit are target, determine well pattern type, cloth well density and pressing crack construction scale, make hydraulic fracturing with
Reservoir engineering combines even closer, makes it possible the Efficient Development of low permeability oil field.Traditional fracturing string is using step by step
The pressure break that stifled mode realizes multi-section multi-layer is thrown, it is less efficient, and down-hole pressure can not be monitored in real time, it uses more not
Just.
Utility model content
The purpose of this utility model is to provide a kind of well cementation fracturing technology tubing strings, to solve the above technical problems.
The utility model uses following technical scheme to achieve the above object：
A kind of well cementation fracturing technology tubing string, including：Tube body, safety joint, permanent packer, pressure break mechanism, throttling ball seat,

Both ends are equipped with packer 8 and water anchor 7 successively respectively, and the sanding machine 9, water anchor 7, packer 8 are connect with tube body 1.
The utility model can carry out multilayer pressure by the number of geology structural adjustment pressure break mechanism 4 and interval where oil reservoir
Mechanism concurrent fracturing is split, oil reservoir aerial drainage rate is effectively improved, promotes oil recovery efficiency, water anchor 7 is fixed on the borehole wall, to improve stabilization
Property, confined space is formed after upper and lower two packers 8 unlatching, sanding machine 9 is opened, and makes to be full of highly pressurised liquid in confined space, with
Realize the pressure break both sides borehole wall；Pressure sensor 6 inside pressure break mechanism 4 monitors liquid pressure data in real time, and passes on well
Staff is conducive to control construction speed in order to grasp bottom pressure variation in real time.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention with spirit, the change that is carried out to embodiment is repaiied
Change, replace and modification is still fallen within the scope of protection of the utility model.
