Description
Technical field
The utility model relates to the Drill Pipe Technology field for mash gas pumping drilling construction, refers to especially a kind of soft seam drilling rod.
Background technology
In coal mining process, often need rig to get out gas extraction hole and get rid of gas and the pressure thereof in coal seam, obtain the parameter such as gas bearing capacity, density, to improve coal mining efficiency and safety simultaneously.The most of coal geology complex structure of China, especially weak seam proportion in minable coal seam is larger, and it is soft that projecting coal bed because ature of coal is soft, gas bearing capacity is high, and drilling construction is very difficult, easily occurs spray orifice, the hole that collapses, the anomaly such as cave in.
At present the gas extraction hole drilling rod of application is mainly round bur bar, Rhizoma Sparganii circular arc drilling rod and three kinds of auger stems (as shown in Figure 1, Figure 2 and Figure 3), all belongs to naked drilling rod above.In drilling process, easily there is spray orifice, hole or the phenomenon of caving in collapse; in addition when hole drill is during to longer length; once after rig disorderly closedown; easily cause the phenomenons such as drilling rod bit freezing, stick of tool, locking, fracture when restarting; thereby cause the problems such as Completion of Drilling Hole rate is low, the shallow even construction of depth of pore forming stagnation; what had a strong impact on gas in coal seam takes out effect in advance, has reduced coal mining efficiency and safety.
Utility model content
The utility model proposes a kind of novel soft seam drilling rod, solve in prior art when drilling rod is restarted due to hole wall collapse, gas spray orifice, the anomalies such as hole that collapse and rig in drilling process, the drilling rod bit freezing, stick of tool, locking, the fracture that easily cause, thereby cause creeping into, become the technical problems such as porosity is low.
The technical solution of the utility model is achieved in that
Novel soft seam drilling rod, comprise: drilling rod body and the through hole that is arranged on drilling rod body inside, on the outer wall of drilling rod body, be provided with auger stem assembly, auger stem assembly comprises the helical blade being evenly arranged on outer wall and is fixedly mounted on interior six side's connectors and outer six side's connectors of through hole both sides, helical blade outer side covers has external jacket, connects and relatively rotate between auger stem assembly and external jacket by support set.
Preferably, through hole is high pressure gravity vent or limbers.
Preferably, drilling rod body is alloy steel drilling rod body, and external jacket is the special seamless steel pipe of petroleum geology.
Preferably, between outer six side's connectors and through hole, be provided with seal.
Preferably, seal is O RunddichtringO.
The beneficial effects of the utility model are:
1. center drilling rod adopts auger stem, and to increase drilling efficiency, inclination angle, pitch and the external diameter of spiral can be selected according to soft projecting coal bed hardness factor f;
2. pair auger stem adds external jacket, drilling rod is played to protection and supporting role, to prevent that bit freezing, stick of tool, locking phenomenon from appearring in drilling rod;
3. auger stem center is provided with high pressure ventilation (water) hole, can form wind-force or automatic control and make chip removal more smooth and easy;
4. soft seam drilling rod is designed to common version, can more piece connects, and to increase drilling depth, supernumerary segment, to change joint convenient;
5. the auger body of rod is selected superior alloy steel, external jacket is selected the special seamless steel pipe of high-quality petroleum geology, welding manner between drilling rod body and helical blade adopts advanced friction-welding technique, carry out bulk heat treatmet, make it to have higher intensity and bending resistance degree, thereby improve one-tenth porosity and the depth of pore forming of gas extraction hole, improve coal mining efficiency and safety.
