Abstract

The utility model relates to an integrated tubular column for horizontal well completion and fracturing production. The tubular column comprises a safety valve, a hydraulic anchor, an inserted sealer, a tail pipe hanging sealer, a 4'/2'' tail pipe, expanding open hole packers, bowling sliding sleeves, a pressure sliding sleeve and a float shoe; a vertical well section above a storage layer adopts a sleeve for well completion, and the tubular column in the sleeve is connected in series with the safety valve, the hydraulic anchor and the inserted sealer from top to bottom; and a horizontal well section adopts open holes for well completion, and the well completion tubular column in a 6'' well hole is connected in series with the tail pipe hanging sealer, the 4'/2'' tail pipe, one bowling sliding sleeve, one expanding open hole packers, the other bowling sliding sleeve, the other open hole packer, the pressure sliding sleeve and the float shoe in sequence from top to bottom. The integrated tubular column provided by the utility model adopts one tubular column to realize the open hole well completion, the sectioned fracturing reformation and the commingled production of a horizontal well, thereby solving the problems such as poor fracturing effect caused by the overlong horizontal well section, and the like, and further not only reducing the construction requirement for ground equipment and the operating risk and shortening the construction time, but also saving the production cost and improving the overall development effect.

Description

Horizontal well completion pressure break production integration tubing string
Technical field:
The utility model relates to a kind of down-hole string that is used for horizontal well completion, staged fracturing transformation and combination producing integral process.
Background technology: in horizontal oil gas well manufacturing process,, often will carry out fracturing reform to reservoir in order to improve production of hydrocarbons and exploitation effect.Yet, because producing, existing horizontal well completion technology and later stage pressure break on technology, do not match, there is certain contradiction on each link, thereby is difficult to obtain desirable pressure break and effect of increasing production.And, because oil gas well completion pressure break and to produce be not a down-hole string, cause construction operation excessive cycle, cost too high, oil-gas field development effect and economic benefit are caused harmful effect.
The utility model content: the purpose of this utility model is to provide a kind of well fracturing technological effect of can improving the standard greatly, reduces the horizontal well completion pressure break production integration tubing string that operating risk also can shorten the engineering time greatly, reduce reservoir pollution, reduces production costs.
The utility model is to realize like this.This kind integrated pipe column is by safety valve, hydraulic anchor, plug-in type sealer, tail tube hanging sealer, 4 '/2 " tail pipe, expanding open hole packer, pitching sliding sleeve, pressure sliding sleeve, float shoe are formed; its structure, assembled relation are as follows: the above peupendicular hole section of reservoir adopts cased hole completion, and tubing string is serially connected with safety valve, hydraulic anchor and plug-in type sealer from top to bottom in the sleeve pipe; Net horizontal section adopts barefoot completion, 6 " completion tubular column is serially connected with from top to bottom successively in the well: tail tube hanging packer+4 '/2 " tail pipe+pitching sliding sleeve+expanding open hole packer+pitching sliding sleeve+open hole packer+pressure sliding sleeve+float shoe.In the construction operation process, at first in horizontal bare hole well section, be lowered to according to the completion tubular column that is connected in series with co-relation to design attitude by drilling rod and special tool, throw 1.25 " ball is fallen sealing tubing string in the float shoe; suppress 14Mpa then and set tail tube hanging sealer and expanding open hole packer; load the sealing that 180KN finishes the tail tube hanging sealer, release pressure and load when keep-uping pressure; On carry drilling rod and special tool it separated from tail tube hanging packer, the pipe column tools that breaks away from is proposed from pit shaft then; Be lowered to construction flow string safety valve+2 7/ 8 " oil pipe+hydraulic anchor+2 7/ 8 " oil pipe+plug-in type sealer is to design attitude, and the plug-in type sealer is inserted into and forms excellent sealing in the extension hanger; After ground surface works is in place, begin to carry out fracturing reform: at first well head is suppressed, the pressure sliding sleeve of opening the tubing string end by pressure carries out pressure break to nexine, " the ball; suppress and open interlude pitching sliding sleeve, interlude is carried out pressure break, throw 2.00 " balls at last of and then throwing 1.75, suppress and open outermost section pitching sliding sleeve, fracturing reform outermost section; Pressure break is finished, and drops into combination producing after the discharge opeing.
The utility model adopts integrated pipe column can realize horizontal well barefoot completion, staged fracturing transformation and combination producing with one-trip string, thereby can avoid the long problems such as fracturing effect difference that cause of net horizontal section, both can reduce requirement and the operating risk of construction to ground installation, shorten the engineering time, can save production cost again, improve the whole development effect.
Description of drawings: accompanying drawing is duty of the present utility model and structural representation.
The specific embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is by safety valve 1, hydraulic anchor 2, plug-in type sealer 3, tail tube hanging sealer 4,4/2 tail pipe 5, expanding open hole packer 6, pitching sliding sleeve 7 1, 7 2, pressure sliding sleeve 9, float shoe 10 form.Number in the figure " 8 " is 6 " barefoot intervals.Label " 11 " is a sleeve pipe.
