Description
The utility model relates to a kind of instrument of measuring the electrical stability of mud (drilling fluid) under high-temperature and high-pressure conditions, belongs to the testing performance of drilling fluid instrument.
Domestic this class evaluation method and means of not setting up are not as yet seen similar data introduction abroad yet at present.The electrical stability of at present relevant drilling fluid is measured, and all measures under normal temperature, condition of normal pressure.Because downhole temperature and pressure is all than ground height, mud is different the performance of down-hole and ground mensuration, so can not reflect the down-hole situation truly.Along with the continuous development of drilling technique, for adapting to the needs that bore deep-well, ultra deep well, be real simulation down-hole situation, we have carried out measuring the electrical stability instrument development of drilling fluid under high-temperature and high-pressure conditions.
The purpose of this utility model is to overcome the deficiency of existing electrical stability analyzer, propose a kind of simple in structure, can simulation well under temperature and pressure, and can directly measure the emulsion-breaking voltage of drilling fluid under high-temperature and high-pressure conditions, thereby judge the tester of various drilling fluids at the down-hole electrical stability.
In order to achieve the above object, the utility model is by the following technical solutions: this high temperature and high pressure electrical stabilometer mainly is made up of autoclave body 1, steam jacket 2, temperature controller 3, gauge head electrode 4, pressurizing valve 5 and voltage controller 6, and its technical characterictic is: in the middle of the airtight loam cake that is fixed on autoclave body 1 of gauge head electrode 4; Autoclave body 1 is put into steam jacket 2, and steam jacket 2 directly connects mutually with temperature controller 3; Pressurizing valve 5 is connected with the high pressure pipe joint joint, regulates 5 pairs of autoclave bodies of pressurizing valve, 1 interior mud sample and exert pressure; Gauge head electrode 4 connects mutually with voltage controller 6, and voltage controller 6 is made up of multiturn potentiometer 8, pilot lamp 7, contact-making switch 9 and other element.The groundwork principle of this instrument be direct current by supercharging after, its voltage drop is distributed on potentiometer and the gauge head electrode, the regulator potentiometer resistance value, can change the voltage between the electrode, if rotation multiturn potentiometer knob voltage raises gradually, when electrode punctures sample, can measure its emulsion-breaking voltage, thereby judge its electrical stability.
Compare with existing drilling fluid electricity stabilometer, the utlity model has following advantage: temperature and pressure under (1) energy simulation well, directly measure the emulsion-breaking voltage value of drilling fluid under high-temperature and high-pressure conditions, in order to judge the electrical stability of drilling fluid; (2) this electric stabilometer is simple in structure, the emulsion-breaking voltage data of surveying accurate, good reproducibility.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model.
In the drawings, 1. autoclave body, 2. steam jacket, 3. temperature controller, 4. gauge head electrode, 5. pressurizing valve, 6. voltage controller, 7. pilot lamp, 8. multiturn potentiometer, 9. contact-making switch.
This high temperature and high pressure electrical stabilometer mainly is made up of gauge head electrode, voltage controller, autoclave body, steam jacket, temperature controller, compression system.Gauge head electrode 4 adopts silver alloy to make, and it is embedded on the teflon gauge head of high temperature resistance airtight autoclave body 1 loam cake that is fixed on of gauge head.Voltage controller 6 mainly is made up of multiturn potentiometer 8, contact-making switch 9, pilot lamp 7 and other element.Autoclave body 1 mainly is that sample is enclosed in the high pressure vessel, can add gentleness to it and apply corresponding pressure.Steam jacket 2 adopts resistance-type ring-type heating jackets to connect, and can be warmed to normal temperature to 210 ℃ to autoclave body 1.Temperature controller 3 is used for regulating the heating of steam jacket 2, constant temperature, can be provided with by requirement of experiment is temperature required, cuts off the power supply when temperature is set when reaching, and steam jacket 2 promptly stops to heat, and can carry out constant temperature by set temperature.Pressurizing valve 5, applies relevant pressure and prevents the liquid gasification when the kettle temperature is higher than 100 ℃ for testing liquid provides pressure.
During mensuration, earlier sample is poured in the autoclave body 1, because expanded by heating will take place sample in the process of heating, institute adds sample can not surpass 2/3rds of kettle volume, covers the kettle that gauge head electrode 4 is housed and covers, and tighten six trip bolts.Autoclave body 1 is put into steam jacket 2, the pressure breathing valve rod is connected with the high pressure pipe joint joint, exert pressure by sample in 5 pairs of kettlies of the required adjusting pressure valve of experiment.Attaching plug is inserted the 220V AC Power supply socket, power switch is allocated to the position of " opening ".When reaching predetermined experiment, temperature can measure emulsion-breaking voltage when temperature required.Multiturn potentiometer 8 knobs with voltage controller 6 transfer to zero-bit earlier, the voltage controller plug is inserted on the binding post of electrode gauge head of kettle loam cake, left hand is pinned the button of pilot lamp 7, with right hand clockwise direction rotation scale multiturn potentiometer 8 knobs, voltage raises gradually, when electrode punctured sample, pilot lamp was promptly bright, loosens knob, pin the multiturn potentiometer of index dial, and read scale value, and scale multiply by 2 and is emulsion-breaking voltage, and unit is volt.
