Description
Technical field
The utility model is the equipment of oilfield oil well job execution, is a kind of Casing Failure through wash device.
Background technology
In operation process after oilfield oil well drilling well, in well, surplus drilling fluid often easily produces solid precipitation, cause implementing in operation process drifting and real tag operation and replace out in sleeve pipe mud operation with working fluid time, the problem that frequent generation drift size gauge tool midway is hampered, can not be fulfiled assignment construction smoothly, brings very big puzzlement to the process of bringing in a well.Even if the later stage arrives drifting to requiring position smoothly by constructions such as millings, the mud solid phase deposition be attached on internal surface of sleeve pipe also can cause replacing the not thorough of slurry process, and the attachment cannot effectively removed when replacing out the mud in sleeve pipe with working fluid on internal surface of sleeve pipe, these attachments are not replaced out, can afterwards after well-case perforating along with working fluid enters stratum, cause near wellbore zone oil layer blocking, cause formation damage, reduce in-place permeability, affect the timely and effective production after oil-water well brill completion.For the oil layer pollution effectively removing attachment and bring, often adopt the measure such as pipe cleaning or pickling at present, while increasing cost of production, cause certain injury to sleeve pipe.
Summary of the invention
The purpose of this utility model is a kind of Casing Failure through wash device of design, this device can while the mud utilizing working fluid to replace out in sleeve pipe, effectively can remove and be deposited on various attachment on internal surface of sleeve pipe, drop into Development and Production after making sleeve pipe be in clean conditions, avoid the problems referred to above to occur.
The purpose of this utility model is achieved in that a kind of Casing Failure through wash device, comprise top connection, drift size gauge tool, connector, cross over pipe, spring, gear joint, die nipple, valve ball, top connection, drift size gauge tool, connector, cross over pipe connects successively, spring is placed with in cross over pipe, gear fitting sleeve is contained in outside die nipple, the upper end diameter of bottommost die nipple is greater than the internal diameter of gear joint, its die nipple can be made effectively to be suspended on gear joint, gear joint is connected with the bottom of cross over pipe, the upper end of spring is made to be pressed on the lower surface of connector, the lower end of spring is pressed in the upper surface of die nipple, die nipple can be stretched to cross over pipe, valve ball is located in the upper port of die nipple after top connection drops into.
UNICOM's eyelet is arranged at the bottom of cross over pipe, can produce jet action after valve ball blocks die nipple passage.
The bottom of die nipple is conical, and tapering is 1:4 or 1:6, and the lower end of die nipple is nib shape.
The beneficial effects of the utility model are: after the utility model completes for oil-water well drilling well in operation operation work progress, drift size gauge tool subsidiary on it can realize the drifting effect to pit shaft, simultaneously when the solid precipitation thing produced because of drilling fluid etc. causes its drifting to be hampered, die nipple can stretch cleaning, ensures that it can drifting to tag in fact smoothly.In drifting process, for all kinds of attachments that shaft in wall is left over, connect the condition of waterflood-transmission line at well mouth oil pipe under, UNICOM's eyelet designed by this device can produce jet action after valve ball blocking die nipple passage, utilize the fluid of high velocity jet can realize effectively washing away the object of attachment on the borehole wall, therefore, the utility model can reach purpose of design, realize oil-water well before operation shaft in wall by the effect cleaned up, effective guarantee oil-water well is gone into operation smoothly, avoid the stratum of oil-water well blocked and injury, the adverse effect that further reduction cost of production and other measures produce sleeve pipe.
Accompanying drawing explanation
Fig. 1 is the assembling drawing of the utility model embodiment.
Detailed description of the invention
Below in conjunction with Fig. 1, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises top connection 1, drift size gauge tool 2, connector 3, cross over pipe 4, spring 5, gear joint 7, die nipple 8, valve ball 9.Oil pipe internal thread is arranged at the top of top connection 1, can be connected with operating tool string, top connection 1, drift size gauge tool 2, connector 3, cross over pipe 4 connects successively, spring 5 is placed in cross over pipe 4, gear joint 7 is sleeved on outside die nipple 8, the upper end diameter of die nipple 8 is greater than the internal diameter of gear joint 7, its die nipple 8 is made to be suspended on gear joint 7 reliably, keep off joint 7 to be connected with the bottom of cross over pipe 4 simultaneously, the upper end of spring 5 is made to be pressed on the lower surface of connector 3, the lower end of spring 5 is pressed in the upper surface of die nipple 8, spring 5 has certain pretightning force, die nipple 8 can be stretched in a compressed state in cross over pipe 4, valve ball 9 can directly be located in the upper port of die nipple 8 after top connection 1 drops into, and form positiver sealing with the upper port of die nipple 8, such valve ball 9 can block die nipple 8 inner passage.UNICOM's eyelet 6 is arranged at the bottom of cross over pipe 4, eye diameter is 3-8mm, high-speed jet can be produced under certain pressure effect, drop on the upper port of die nipple 8 like this at valve ball 9 after, fluid is injected continuously from well head, just can form high-speed jet by eyelet 6, in order to rinse the attachment that on shaft in wall, drilling fluid etc. is left over, form a clean shaft in wall.The bottom of die nipple 8 is designed to taper shape simultaneously, taper design is 1:4 or 1:6, the lower end of die nipple 8 is made to form nib shape, this structure is conducive to producing the raw destruction of solid precipitation produce to surplus drilling fluid in well, under resulting fluid injection condition, be rinsed out pit shaft after making it disperse, ensure carrying out smoothly of drifting process.
When using this instrument in operation process, in the first not inserter of valve ball 9, through wash device is connected to the bottom of oil pipe, utilize oil pipe G.I.H, first replace out the mud of remaining drilling well in sleeve pipe afterwards with working fluid, working fluid flows out through the internal channel of die nipple 8 in this process, and positive well-flushing replaces out the mud in sleeve pipe, and replacing out in the sludge process in sleeve pipe by drift size gauge tool sleeve pipe drifting, realize drifting once completing for slurry process.After drifting to artificial bottom of a well, valve ball 9 is dropped into by well head, the corresponding time is waited for according to tubing length, valve ball 9 is under the double action of self gravitation and working fluid thrust, in the upper port dropping down onto die nipple 8 and effectively the internal channel of blocking die nipple 8, makes working fluid form high-speed jet through UNICOM's eyelet 6, carries in the process of oil pipe upper, just can realize effectively washing away the drilling fluid attachment on the full pit shaft borehole wall, ensure wellbore clean.
