Abstract
The invention relates to a completing tool for horizontal wells and large displacement wells, particularly to a guiding tool with a drifting function for downwards running a casing pipe capable of being fished. A casing pipe buckle is designed at the upper end of a casing of the device; the inner wall of the casing is connected with a thrust gland through fixing pins; the lower end surface of the thrust gland is propped against the step of the inner wall of the casing; the thrust gland sleeves a casing of a turbine set; a fishing sleeve is arranged on the outer side of the upper end of the casing of the turbine set; an axial limiting bearing sleeves the lower middle axle of the turbine set; the lower end of the middle axle of the turbine set is connected with a rotary guiding shoe; a scraping belt is arranged on the surface of the rotary guiding shoe. According to the invention, when the casing pipe is downwards placed and encounters a well resisting section, the casing pipe can drive the rotary guiding shoe to rotate at a high speed, thereby having the better drifting function, reducing the downward running difficulty of a casing pipe string and reducing danger; when the casing pipe string is downwards placed to the place of the expected well depth, the tool body can be fished out of the casing pipe without affecting the follow-up construction after well drilling; the defect that the casing pipe at part of the well section of the conventional horizontal wells, directional wells and large displacement wells cannot be downwards placed smoothly is overcome.
Description
Technical field:
The present invention relates to a kind of horizontal well, extended reach well completion tool, particularly a kind of there is the salvagable sleeve pipe of drifting function under enter guiding tool.
Background technology:
In most of wellbore construction, because hole condition is complicated, although can complete the construction of drilling process, in completion setting of casing process, enter the problems such as difficulty under but often there is sleeve pipe, cause setting of casing not smooth, even sleeve pipe cannot enter down.In order to ensure to enter under sleeve pipe smoothly, usually before entering under sleeve pipe, carry out repeatedly drifting operation, and comparatively large for hole condition more complicated, drilling trajectory dog-leg degree, hole diameter is irregular, effect of hole cleaning is poor horizontal well, directional well, extended reach well etc., after having carried out drifting construction, some well section still there will be sleeve pipe cannot smoothly under situation about entering, along with the increase in processing time, down-hole situation is increasingly sophisticated, to enter in process various contradiction under sleeve pipe more and more serious, cause sleeve pipe can not smoothly under enter.Enter difficulty under sleeve pipe, both affected next step wellbore construction, be also provided with obstacle for smooth completion simultaneously.
Summary of the invention:
The technical problem to be solved in the present invention be to provide a kind of there is the salvagable sleeve pipe of drifting function under enter guiding tool, the arrangement achieves the well section that enters to be hampered under sleeve pipe can driven rotary guide shoe High Rotation Speed, there is good drifting effect, difficulty is entered under reducing casing string, reduce risk, when casing string is down to expectation well depth, tool body can be salvaged sleeve pipe, not affect the construction of follow-up brill completion.Overcome existing level well, directional well, extended reach well part well section sleeve pipe cannot smoothly under the deficiency that enters.
The technical solution used in the present invention is: a kind of there is the salvagable sleeve pipe of drifting function under enter guiding tool, comprise shell body; Shell body upper end is designed with cover pipe thread, shell body inwall connects thrust gland by fixing pin, thrust gland lower surface withstands on shell body inwall step place, thrust gland is sleeved on the shell of turbine group, fishing sleeve is provided with outside the shell upper end of turbine group, the bottom axis of turbine group is set with axial limiting bearing, and the axis lower end of turbine group connects rotary guide shoe, and rotary guide shoe surface is provided with scraping band.
The invention has the beneficial effects as follows: the present invention owing to have employed the mode of turbine group driven rotary guide shoe High Rotation Speed, thus enter to be hampered under sleeve pipe well section time there is good drifting effect, reduce under casing string and enter difficulty, reduce risk; Owing to have employed fishing sleeve, when thus casing string is down to expectation well depth, tool body can be salvaged sleeve pipe, not affect the construction of follow-up brill completion.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
As shown in Figure 1, a kind of there is the salvagable sleeve pipe of drifting function under enter guiding tool, comprise shell body 1; Shell body 1 upper end is designed with cover pipe thread, shell body 1 inwall connects thrust gland 6 by fixing pin 5, thrust gland 6 lower surface withstands on shell body 1 inwall step place, thrust gland 6 is sleeved on the shell of turbine group 2, fishing sleeve 3 is provided with outside the shell upper end of turbine group 2, the bottom axis of turbine group 2 is set with axial limiting bearing 4, and the axis lower end of turbine group 2 connects rotary guide shoe 7, and rotary guide shoe 7 surface is provided with scraping band.
Shell body 1 is designed with cover pipe thread, can be connected with casing string; Turbine group 2 can rotate when circulation of drilling fluid, and then drives the rotary guide shoe 7 of front end to rotate, and the scraping band in rotary guide shoe 7 can process shaft bottom desilting, reducing position etc., makes well reach perfect condition; Axial limiting bearing 4 pairs of turbine groups 3 play the effect of restriction, avoid instrument to produce axially-movable; Thrust gland 6 can apply axial force to whole tubing string, and then pushing set tubing string is migrated downwards, reaches projected depth; Fishing sleeve 3 upper end is designed with salvages button, after desired depth can being entered under tubing string, by under enter to salvage drilling tool and salvage; After reaching design well depth, by carry salvaging drilling tool, fixing pin 5 can be cut off, salvage casing string by except the whole instrument of shell body 1, carry out completion.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
