Description
Technical field
The utility model relates to drilling tool field, particularly the drilling tool of a kind of down-hole microwave auxiliary rock.
Background technology
At present, oil-gas exploration and development wellbore construction still adopts traditional mechanical drilling technology, although the advanced persons' such as application gas drilling drilling technology can significantly improve rate of penetration, but, super deep formation dark at some particularly high temperature rock mass geothermal energy production drilling construct in because the rocks such as granite, basalt are very hard, cause rate of penetration extremely slow, bit wear is serious, removes that more bit change is frequent, had a strong impact on drilling well timeliness, wellbore construction cost is exponential increase.For solving the broken rock difficult problem of solid rock, experts and scholars are just utilizing the New well drilling methods such as laser drill, electric spark drill to break rock in exploratory development both at home and abroad, but still exist many technical problems to can not get solving.
In the last few years, in mining activities, seeking new rock breaking method, to realize the continuous exploitation of ore deposit rock be the target that mining industry circle is striven for always.For the non-coal mine of hard rock class, the coal excavation apparatus based on machine cut lacks competitiveness economically because of tool wear, or because penetraction depth line and maintenance capacity increase and can not realize enough production capacity; Even if adopt the broken rock of water slug tests, have too the broken rock limit.But, the technologic broken rock limit when technique that simultaneously adopts two or more input energy to combine likely breaks through alone a kind of energy input.Owing to having, heating does not need medium heat-transfer to microwave, programming rate is fast, penetrability is strong, process is easy to the features such as control, becomes a kind of important auxiliary rock means, and this technology, at present in the exploratory stage, has obtained certain effect.
Summary of the invention
The purpose of this utility model is to provide the drilling tool of a kind of down-hole microwave auxiliary rock, can solve the very broken rock difficult problem of solid rock such as granite in dark, super deep formation, basalt, overcome the deficiency of traditional mechanical drilling technology, can avoid drill bit heavy wear, increase drilling life of bit, reduce the number of times that makes a trip, significantly improve rate of penetration, reduce wellbore construction cost, be suitable for dark, super deep firm hard formation gas drilling construction.
For solving the problems of the technologies described above, the utility model proposes the drilling tool of a kind of down-hole microwave auxiliary rock, comprise drill string, electricity cable, electrodrill, stub boring quickly, microwave generation module and tricone bit, in gap between three palms of tricone bit, 1 microwave antenna is set, microwave generation module be arranged on stub boring quickly and drilling fluid passage between annular space in, in stub boring drilling fluid passage quickly, be provided with waveguide, microwave generation module is connected by waveguide with microwave antenna, electrodrill is its power supply by the electricity cable that is positioned at the drilling fluid passage of drill string, electrodrill is connected by interface module with microwave generation module.The critical piece of described microwave generation module is 2.45GHz magnetron.Described electricity cable is two core flexible rubber cables.Described waveguide is metal catheter, according to the difference of transmission mode, can be rectangle or circular cross-section.Described electrodrill is the drilling equipment at shaft bottom driving bit with submersible electric motor of Russia's development.
The operating principle of microwave rock fragmenting is microwave by heating rock mass and then changes its physical characteristic.Described in specific as follows, rock is comprised of many one end positively charged, the electronegative dipole of the other end, and does rambling motion, and arranges unordered.In electric field, after pressurization, inner dipole will rearrange, and become and have certain direction regularly arranged, under alternating current effect, polarization, makes interior of articles produce similar friction repeatedly, temperature raises, thereby produces internal stress, and rock mass destroys under moisture evaporation, interior partial solution, expansion.Heating using microwave is different from traditional mode of heating, is a kind of body heating, does not only need heat transfer medium, nor needs the process of hot transmission, convection current and radiation.Can be used as a good auxiliary rock instrument, by heating, change the physical characteristic of rock mass, reduce formation hardness.
The beneficial effects of the utility model are: microwave antenna is directly installed on tricone bit, the microwave energy heating rock of transmitting, the physical characteristic of change rock mass, reduces formation hardness, the broken rock of auxiliary drill bit, can improve the rate of penetration that the solid rocks such as granite, basalt creep into.
