Abstract
The utility model relates to a rapid cementer of a drilling completion running casing, which is particularly used for quickly filling the running casing with drilling fluid of the orientation well and the horizontal well. The utility model comprises a protecting connector (1), a sleeve coupler (4), a self sealing type packer (5), and a pressure differential type packer (7), wherein the protecting connector (1) is connected with an elevator (2), the both ends of a hoisting ring are respectively connected with an elevator (2) and an elevator (6), the sleeve coupler (4) is arranged on the sleeve (9), the self sealing packer (5) and the pressure differential type packer (7) are installed inside the sleeve (9), a guide shoe is installed at the bottom part of the pressure differential type packer (7), therefore the damage of the drilling fluid to the sleeve outside the well bore sleeve is reduced, and the running casing speed is accelerated. The drilling fluid can be filled at any moment, and the running time is reduced; the well accident is reduced, the well bore can be cleaned in time; the cementing qualification rate is ensured. The device is adopted to perform the running, in particular to the application in the orientation well and the horizontal well, and the superiority of the device can be reflected better.
Description
Technical field
The utility model relates to the quick provisions for grouting of a kind of drilling completion setting of casing, be adapted to directional well especially, the horizontal well setting of casing is filled the drilling fluid instrument to the sleeve pipe that is lowered to fast, fast the sleeve pipe that is lowered to is filled the isolated plant of drilling fluid when being a kind of completion setting of casing that is applicable to all size well.
Background technology
Mostly adopting kelly bar to connect circulating connection during present domestic drilling completion setting of casing grouting connects the sleeve pipe turn on pump that is lowered to and circulates, it is untimely to be in the milk, at any time moving casing has been wasted a large amount of time, and existing kit does not satisfy the setting of casing requirement of grouting fast.
Summary of the invention
The purpose of this utility model is to provide a kind of setting of casing quick provisions for grouting, is connected (or down) protection joint bottom, can finish quick grouting task; Reduce of the crowded damage of ruining of the outer drilling fluid of wellbore casing, accelerate setting of casing speed sleeve pipe; Reciprocate casing is reduced in the effect of the sticking card during the drilling fluid charge; At any time the filling drilling fluid is saved the setting of casing time; Reduce down-hole accident; In time clean pit shaft; Guarantee qualification rate of cementing.
The technical solution adopted in the utility model is:
The beneficial effects of the utility model: simple in structure, sealing is reliable, with low cost, handling ease, do not change original characteristics such as setting of casing program, it can fill drilling fluid to the sleeve pipe that is lowered to fast when the completion setting of casing, reduce the crowded damage of ruining of the outer drilling fluid of wellbore casing to sleeve pipe, accelerates setting of casing speed.This instrument can also play reciprocate casing, is reduced in the effect of the sticking card during the drilling fluid charge, and filling drilling fluid at any time, saves the setting of casing time; Reduce down-hole accident; In time clean pit shaft; Guarantee qualification rate of cementing.Adopt this device to carry out setting of casing, particularly in directional well, horizontal well, use, more can embody its superiority.Grouting rapidly; Circulation at random; At any time reciprocate casing etc.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings; form by protection joint 1, elevator 2, suspension ring 3, casing coupling 4, self-packing packer 5, elevator 6, differential packer 7, guide shoe 8; protection joint 1 is connected with elevator 2; the two ends of suspension ring 3 are respectively with elevator 2, elevator 6 and be connected; casing coupling 4 places on the sleeve pipe 9; self-packing packer 5, differential packer 7 are installed in the sleeve pipe 9, and guide shoe 8 is equipped with in the bottom of differential packer 7.
Claims (2)
