Description
Technical field
The present invention relates to a kind of rock-breaking drilling experimental provision, especially a kind of experimental provision of realizing rock-breaking drilling under the HTHP that is applicable to.
Background technology
Along with development of human society, more and more such as the engineering problem that deep oil-gas mining, the exploitation of high temperature rock mass underground heat, underground coal gasification(UCG) etc. are relevant with temperature.For example: the degree of depth of petroleum drilling has reached 8000m, and high temperature rock mass geothermal energy resources mining depth is more than 5000m, and the underground coal gasification(UCG) temperature is also more than 1000 ℃.These engineerings all relate to a major issue relevant with high-temperature and high pressure; Promptly under high temperature and high pressure environment, hard rock mass being broken rock creeps into; This presses for the rock breaking mechanism problem that solves hard rock mass under the high-temperature and high-pressure conditions, and does not still have the experimental provision of rock-breaking drilling under this condition of simulation at present.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, the broken rock experimental provision under a kind of simple in structure, easy to operate, HTHP that test effect is good is provided.
For realizing above-mentioned purpose; Broken rock experimental provision under the HTHP of the present invention comprises press, is located at the high temperature pressure chamber of in the press rock sample being heated, and the top of high temperature pressure chamber is provided with the rock sample seaming chuck; The bottom is provided with central cylinder pressure head and the confined pressure cylinder pressure head that rock sample is pressurizeed; The top of said press is provided with to the indoor platform of drilling of executing brill of high temperature pressure, the rig support that the platform of drilling is provided with, and being hinged with on the rig support can be around the rig crossbeam of rig support rotation; The rig crossbeam is provided with rig and rig fixed bar; Rig is provided with the water inlet that feeds drilling rod, and the middle part of the platform of drilling is provided with the drilling rod passage, and the porch of drilling rod passage is provided with the slag-draining device that imports drilling rod.
The welding of described rig fixed bar top and rig crossbeam, bottom through screw retention on the platform of drilling; Described slag-draining device comprises the guide pin bushing that communicates with the drilling rod passage and is located at the deslagging water delivering orifice on the guide pin bushing.
Beneficial effect: can realize rock sample is heated and carry out when pressurizeing the rock-breaking drilling experiment, can be according to different experiments purpose adjustment drilling parameter and broken rock mode, its drilling rod can be installed dissimilar drill bits; Drilling rod gets into the high temperature pressure chamber through the drilling rod passage at the platform center of drilling, and arrives the upper surface center of rock sample; Water purification arrives rock sample boring through the inlet opening in the drilling rod, and the landwaste that gets out is taken out of through the drilling rod passage, discharges through the deslagging water delivering orifice.Can carry out the research of creeping into aspects such as speed, efficiency of breaking rock, drilling tool and country rock interaction of the broken rock mode of impact-cutting under the high-temperature and high-pressure conditions.It is simple in structure, easy to operate, test effect is good.
