The effect of the convenient multifunctional horizontal discharger is beneficial in that, the utility model discloses a horizontal well packer sliding sleeve staged fracturing tubular column can adapt to high temperature high pressure peracid environment and use down, simultaneously can real time monitoring stratum information, and safe and reliable, economical and practical.
Description
Technical field
The utility model belongs to staged fracturing of horizontal well technical field, particularly relates to horizontal well packer sliding sleeve fracturing strings.
Background technology
Begin one's study the eighties in 20th century fracturing yield increasing renovation technique of horizontal well both at home and abroad, in crack initiation, the extension of hydraulic fracture, production forecast after horizontal well pressure, the optimization of hydraulic fracture number and Fracture geometric size, the aspects such as staged fracturing construction technology technology and down-hole separation instrument achieve certain progress.
In recent years, domestic petroleum field, for horizontal well characteristic, devises staged fracturing operating tool string, these tubing strings or be carry out pressure break piecemeal, or carries out general pressure break.For meeting the requirement of safe and efficient operation under high pressure, high yield, peracidity condition, realizing the acid of long well section Uniform Horizontal Well cloth, improving reservoir reconstruction effect, needing supporting well-completing process and tubular column structure pointedly.
Therefore, need a kind of horizontal well packer sliding sleeve fracturing strings, use under HTHP high acid environment can be adapted to, formation information can be monitored in real time simultaneously, simultaneously safe and reliable, economical and practical.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, and the utility model provides a kind of horizontal well packer sliding sleeve fracturing strings.
The utility model solves the technical scheme that its technical problem adopts: horizontal well packer sliding sleeve fracturing strings, comprise body, oil pipe is provided with in described body, described oil pipe and body are with circular parallel distribution, described oil pipe is connected safety valve, checkout gear, circulation slide sleeve, permanent packer, hanging packer, open hole packer, bridging plug successively, described checkout gear is provided with sensor unit, and described open hole packer at least installs two-stage.
Further, described permanent packer and hanging packer are provided with hydraulic anchor.
Further, described open hole packer is provided with pitching sliding sleeve.
Further, described bridging plug is provided with partition ball seat.
Further, described open hole packer is provided with filter sand core.
Further, described permanent packer, hanging packer, open hole packer adopt plug-in type to connect.
The beneficial effects of the utility model are, horizontal well packer sliding sleeve fracturing strings of the present utility model, how can use under HTHP high acid environment, can monitor formation information in real time simultaneously, safe and reliable, economical and practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, body, 2, oil pipe, 3, safety valve, 4, checkout gear, 5, circulation slide sleeve, 6, permanent packer, 7, hanging packer, 8, open hole packer, 9, bridging plug, 10, sensor unit, 11, pitching sliding sleeve, 12, cut off ball seat.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, horizontal well packer sliding sleeve fracturing strings of the present utility model, comprise body 1, oil pipe 2 is provided with in described body 1, described oil pipe 2 and body 1 are with circular parallel distribution, described oil pipe 2 is connected safety valve 3, checkout gear 4, circulation slide sleeve 5, permanent packer 6, hanging packer 7, open hole packer 8, bridging plug 9 successively, and described checkout gear 4 is provided with sensor unit 10, described open hole packer 8 at least installs two-stage.
As the further improvement of technique scheme, described permanent packer 6 and hanging packer 7 are provided with hydraulic anchor.
As the further improvement of technique scheme, described open hole packer 8 is provided with pitching sliding sleeve 11.
As the further improvement of technique scheme, described bridging plug 9 is provided with and cuts off ball seat 12.
As the further improvement of technique scheme, described open hole packer 8 is provided with filter sand core.
As the further improvement of technique scheme, described permanent packer 6, hanging packer 7, open hole packer 8 adopt plug-in type to connect.
Horizontal well packer sliding sleeve fracturing strings of the present utility model, by the construction parameter such as discharge capacity, pressure of simulation subsection acidizing construction, in conjunction with interlayer card envelope section voltage endurance capability, determine that cased well horizontal segment adopts hydraulic compression formula packer layered, voltage withstand class is high, open hole well horizontal segment adopts hydraulic expanding packer layered, the downhole tool such as safety valve, packer, circulation slide sleeve of all the other string matchings all adopts high voltage withstand class, all adopts acidproof nickel-base alloy according to downhole temperature, acid condition, instrument.Tubing string once enters down, can meet acid fracturing and produce connection work, adopt plug-in type to be connected, can put tubing string aside by back-off where necessary between packer with tubing string.
In order to adapt to high-pressure situations, solve the withstand voltage weakness at casing shoe place, reservoir top design twin packer structure.To the horizontal well of development requires long term monitoring formation temperature, PRESSURE DATA, permanent packer upper design checkout gear, for detecting the parameters on stratum, provides foundation for normally running.Bridging plug bottom tubing string and cut off ball seat and have direct circulation and prevent function that gas is altered.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
