Abstract
The invention discloses a high-temperature high-pressure dilatometer, relating to a monitoring device for the strata material expansion ratio in petroleum exploitation, comprising a heater, an experiment cup body inside the heater, and a water supply cup and a non-contact displacement transducer communicated with the experiment cup body. The high-temperature high-pressure dilatometer is characterized in that: a barrel-shaped shell is arranged on the upper part of the experiment cup body; an insulation layer is arranged between the shell and the experiment cup body; the non-contact displacement transducer is arranged inside the shell; the transducer bar extends in the experiment cup body; a heat dissipation fan is arranged on the upper part of the transducer. The high-temperature high-pressure dilatometer overcomes the disadvantages that a common contact dilatometer has low detection precision and a non-contact dilatometer cannot work in high-temperature situations.
Description
Technical field:
The present invention relates to the monitoring instrument of formation material expansivity in a kind of oil exploitation, is a kind of high-temperature high pressure dilatometer specifically.
Background technology:
In drilling especially oil exploitation, need to realize detecting the expansivity of bottom material usually, guarantee that drill bit is not pushed by or not the stratum so that in probing, add suitable antiswelling agent.Therefore dilatometer is the important monitoring instrument in the oil exploitation, detect expansivity by dilatometer simulate formation pressure and temp, what existing common dilatometer was more is the contact dilatometer, but the spirit that touch sensor is detected by the influence of self friction power is precisely not high, the data that obtain are often not accurate enough, along with the development non-contacting sensor of technological innovation begins research and development and uses, but owing to expand is to detect under the simulate formation high-temperature high-pressure state, common non-contacting sensor can't be high temperature resistant, therefore can't simulate operate as normal under the hot conditions.
Goal of the invention:
The present invention aims to provide a kind of novel high-temperature high pressure dilatometer, has solved the shortcoming that not high, the contactless dilatometer high temperature of common contact-type dilatometer accuracy of detection turntable can't be worked.
Summary of the invention:
In order to realize this goal of the invention, high-temperature high pressure dilatometer of the present invention is achieved by the following scheme:
A kind of high-temperature high pressure dilatometer, comprise the experiment cup of well heater, well heater inside and be communicated with it give water tumbler, non-contact displacement transducer, be characterised in that, experiment cup top is provided with the tubbiness housing, be provided with thermofin between tubbiness housing and the experiment cup, non-contact displacement transducer is arranged in the tubbiness housing, and rodmeter extend in the experiment cup, and sensor top is provided with heat emission fan.Non-contact displacement transducer makes heat be not easy to pass to sensor with the split setting of experiment cup, and the heat emission fan that top is provided with has further reduced the temperature in the housing, guarantees normal operation of sensor
Described high-temperature high pressure dilatometer, described housing is provided with louvre, is to be stored in the interior heat of housing in time to distribute.
Aforesaid high-temperature high pressure dilatometer is given between water tumbler and the experiment cup and is provided with water-supply valve, the control water injection rate.
Aforesaid high-temperature high pressure dilatometer is respectively equipped with gas source connector for water tumbler and experiment cup, pressurizes, adds water respectively by gas source connector.

Embodiment:
Be somebody's turn to do the embodiment of inventing below in conjunction with description of drawings, but not as the qualification to summary of the invention:
High-temperature high pressure dilatometer as shown in Figure 1 comprises that well heater 9, well heater 9 inside are provided with experiment cup 8 and to water tumbler 13, experiment cup 8 and be connected to water tumbler 13, between be provided with water-supply valve 14.Experiment cup 8 is respectively equipped with gas source connector 6,12 with giving water tumbler 13.Experiment cup 8 tops are provided with tubbiness housing 2, be provided with thermofin 5 between tubbiness housing 2 and the experiment cup 8, tubbiness housing 2 inside are provided with in the non-contact displacement transducer 11,11 rodmeter 3 extend in the experiment cup 8 in the non-contact displacement transducer, non-contact displacement transducer 11 tops are provided with heat emission fan 1, and tubbiness housing 2 is provided with louvre 4.
During use, sample 7 is put into 8 sealings of experiment cup, add water by gas source connector 6,12, rodmeter 3 is pressed on the sample 7, rodmeter 3 moves when sample 7 expands, non-contacting sensor 11 monitors signal, is sent to computing machine by signal transmssion line 10.
