Description
Technical field
The utility model belongs to drilling applications, relates to a kind of oil drilling device and technique, and the special design one drop ply segment table layer that collapses bores completion system and technique continuously.
Background technology
In drilling process, be all generally first by drilling tool drilling well, trip out drilling tool after having bored, setting of casing is cemented the well.When drilling well runs into shallow table stratum landslide section, bore chance collapse drop ply section can produce bore without drilling depth, drilling fluid is lost, bore the complex situations such as rear landslide completion setting of casing is hampered, the method of current this type of situation of solution is exactly add anti-sloughing agent to drilling fluid, sealing agents etc. improve property of drilling fluid, if run into the stratum that geological condition is extremely complicated, current employing be top layer bore well-completing process, i.e. shallow top layer drilling completion, object is in oilfield drilling, cave in prevent shallow table stratum, a good circulation canal is provided and the drilling technology that must complete to drilling fluid during subsequent well, but this method can not thoroughly solve the problem.Therefore, need to design and a kind ofly to collapse the brill completion system of drop ply section and technique for stratum.
Summary of the invention
The purpose of this utility model is to provide the one drop ply segment table layer that collapses and bores completion system continuously, solves at present in the drilling process of top layer, bore meet brill that drop ply section of collapsing occurs lose without drilling depth, drilling fluid, bore after all kinds of complex situations such as landslide completion setting of casing is hampered.
The utility model is achieved through the following technical solutions: the one drop ply segment table layer that collapses bores completion system continuously, comprise drill bit, sleeve pipe, supply slurry joint, casing coupling and sleeve pipe rotating disk, described drill bit and cannula tip affixed, many sleeve pipes are connected successively by casing coupling, and on sleeve pipe and casing coupling, longitudinal measure has entire body block key; Be equipped with for slurry joint between adjacent two sleeve pipes, described comprises joint body, one way valve one and one way valve two for slurry joint, and one way valve one is contained in joint body top, and one way valve two is contained in joint body side; Described sleeve pipe rotating disk is enclosed within outside of sleeve, and is welded with the block that can match with entire body block key inside sleeve pipe rotating disk.
Adopt the good effect of technique scheme: the utility model employing sleeve pipe substituted for original drilling rod and carries out drilling well, achieve the object of driving casing drilling without top, creeping into makes up a joint realizes continuous circulation, through collapse drop ply section time need not anti-collapse leakproof, namely complete setting of casing operation while being drilled into target zone, after well cementation, adopt the junk mill of corresponding size can carry out two spudding wells by worn out to " drillable three wings drag bit ".
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
In figure, 1 drill bit, 2 sleeve pipes, 3 casing couplings, 4 sleeve pipe rotating disks, 5 entire body block keys, 6 joint bodies, 7 one way valve one, 8 one way valve two, 9 blocks.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:
Embodiment 1
Fig. 1 is structural representation of the present utility model, Fig. 2 is top view of the present utility model, as shown in the figure, the one drop ply segment table layer that collapses bores completion system continuously, comprise drill bit 1, sleeve pipe 2, for slurry joint, casing coupling 3 and sleeve pipe rotating disk 4, described drill bit 1 is affixed with sleeve pipe 2 end, original drilling rod is substituted for by sleeve pipe, many sleeve pipes 2 are connected successively by casing coupling 3, on sleeve pipe 2 and casing coupling 3, longitudinal measure has entire body block key 5, because sleeve pipe is circular, on sleeve pipe and casing coupling, longitudinal measure has the object of entire body block key to be convenient to sleeve pipe rotating disk rotate sleeve pipe, carry out drillng operation.Be equipped with for slurry joint between adjacent two sleeve pipes 2, described comprises joint body 6, one way valve 1 and one way valve 28 for slurry joint, and one way valve 1 is contained in joint body 6 top, and one way valve 28 is contained in joint body 6 side.Effect for slurry joint is connected with slush pump, inject drilling fluid, and the effect of two one way valves is the flow directions that can control drilling fluid in sleeve pipe.Described sleeve pipe rotating disk 4 is enclosed within outside sleeve pipe 2, and is welded with the block 9 that can match with entire body block key 5 inside sleeve pipe rotating disk 4, and block and entire body block key have coordinated the moment of torsion transmission of rotary drilling.
Embodiment 2
The use drop ply segment table layer that collapses bores the brill well-completing process of completion system continuously, it is characterized in that: this technique comprises the following steps:
(1) by drill bit 1 and first sleeve pipe 2 end affixed, sleeve pipe rotating disk 4 is enclosed within outside sleeve pipe 2, rotary drilling, slush pump connect for slurry joint top one way valve 1 supply drilling fluid; Owing to having certain pressure when drilling fluid injects, about 2-3MPa, under pressure, the one way valve two for slurry joint side is now in closed condition;
(2) make up a joint sleeve pipe on first sleeve pipe 2, and slush pump connects the one way valve 28 supply drilling fluid for slurry joint side; Under the pressure effect of drilling fluid, the one way valve one for slurry joint top is now in closed condition, is convenient to make up a joint sleeve pipe on sleeve pipe;
(3) so circulate, drilling well completes, many sleeve pipes 2 connect complete, namely setting of casing operation is completed while being drilled into target zone, owing to having eliminated drilling rod cased operation again again, therefore can avoid boring meet brill that drop ply section of collapsing occurs lose without drilling depth, drilling fluid, bore after all kinds of complex situations such as landslide completion setting of casing is hampered.
The utility model employing sleeve pipe substituted for original drilling rod and carries out drilling well, achieve the object of driving casing drilling without top, creeping into makes up a joint realizes continuous circulation, through collapse drop ply section time need not anti-collapse leakproof, namely complete setting of casing operation while being drilled into target zone, after well cementation, adopt the junk mill of corresponding size can carry out two spudding wells by worn out to " drillable three wings drag bit ".Because shallow top layer, stratum is general harder, be soft drop ply section of collapsing under hard shallow top layer, therefore, casing drilling can be used from the beginning, also can adopt existing method, with drilling rod at hard drilling, be drilled into soft drop ply section of collapsing, pull out of hole, then use casing drilling instead and also can.The utility model succeeds in field produces, has broad application prospects.
