Description
Technical field
The utility model belongs to oil and gas wellbore stability field, is specifically related to a kind of rock of measuring in real time under different temperaturesWater absorption laboratory apparatus.
Background technology
Oil/gas Well borehole well instability is one of major issue of running into of oil and gas exploitation, and in shale gas drilling process, the borehole wall losesSteady problem is particularly serious. If borehole well instability can not get administering, the piece that caves in can fall into well and cause bit freezing lamp accident. In addition withDrilling fluid and enter stratum, the hydration of rock can make rock strength reduce, and causes more serious borehole well instability phenomenon. RockIt is two aspects that stone aquation strength retrogression endangers main manifestations: the piece that caves in causes the initial cracking pressure of rock in bit freezing, fracturing processCalculate inaccurate. Seem particularly important for intensity after computing rock aquation, the soaked rear intensity experiment of current indoor rock is more normalWith method, and for experiment key be to obtain rock rock core water absorption rule over time under different temperatures, this is justTo measure in real time in laboratory the water absorption of rock, the rock core intensity under different water absorptions is tested, set up rock strength withMoisture content variation relation, and rock water absorption relation over time under different temperatures. Through investigation in many ways, at present pinAlso not too perfect to this water absorption measuring instrument, be the water absorption of directly measuring after water suction certain hour mostly, and normal temperature and pressureUnder water absorption, the shortcoming of this kind of device is: cannot measure the rock core water absorption under different temperatures, and cannot measure rock core inhaleWater yield temporal evolution relation, therefore, need to develop a kind of experimental provision of energy real time record rock core water absorption, and can controlSolution temperature simulation subsurface environment processed.
Summary of the invention
The purpose of this utility model is: for intensity experiment after indoor rock aquation provide a kind of can real time record the reality of rock core water absorptionExperiment device, can control rock core water absorption like this, and the rock core of different water absorptions is carried out to intensity experiment, can control solution simultaneouslyTemperature, and obtain rock water absorption rule over time.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of rock water absorption laboratory apparatus under different temperatures of measuring in real time, this laboratory apparatus is characterised in that, top is rectangleSupport, bottom is base, the high 15cm of described rectangle support is long is 10cm for 15cm is wide, on rectangle support, have preformed hole,Temperature sensor, heating magnetic stirrer, radiator valve, temperature sensor can be measured the interior solution temperature of beaker and feed back toRadiator valve, has beaker on heating magnetic stirrer, and beaker is built-in with magnetic stirring bar, rock core hangs cage, magnetic stirring barCan make solution evenly heat up, radiator valve control solution temperature maintains design temperature, has electronics sky on described baseFlat, rock core suspension holdfast contacts with bottom electronic balance through preformed hole, the quality after measurement rock core that balance can be real-time is soaked,And be transferred to computer record, and rock core suspension holdfast one end hangs with rock core and hangs cage, and rock core hangs can place each size in cageRock core.
The beneficial effects of the utility model:
Can be found out a kind of rock water absorption laboratory apparatus under different temperatures, this device measured in real time by above-mentioned technical schemeCan measure rock core water absorption temporal evolution relation, and control solution temperature, principle is simple, easy to operate, meets requirement of experiment.
