Abstract
The invention relates to a temperature measuring device, in particular to a measuring probe used for measuring the mud temperature. The structure of the existing borehole temperature measuring probe is that a temperature probe is directly connected with a matrix and a seal ring is used to isolate the silicone oil in the probe and the mud outside the probe; and as the thermal conductivities of the temperature probe and the matrix are better, the measured mud temperature is not accurate. The invention provides a borehole temperature measuring probe. The borehole temperature measuring probe contains a matrix and a probe, wherein a seal ring is arranged between the installation part of the probe and the matrix. The invention is characterized in that an isolating jacket is arranged between the installation part of the probe and the matrix. The isolating jacket is prepared from a nonmetallic material with low thermal conductivity. When the mud temperature is measured and the heat of the matrix is transferred to the probe, as the isolating jacket is arranged in the middle for isolation, the heat conduction process is extremely slow. Therefore, the influence of the temperature of the matrix on the temperature measurement of the probe is extremely small and the accuracy of the temperature measured by the probe is increased.
Description
Technical field:
The present invention relates to a kind of oil well logging instrument, specifically refer to a kind of measuring probe that is used to measure wellbore temperatures.
Background technology:
In the oil well logging field, it is very important for interpretation of logging data accurately to measure wellbore temperatures.The structure of existing a kind of temperature measurement probe is directly to be linked to each other with matrix by temp probe, and adopts isolated interior silicone oil and the outer mud of probe of popping one's head in of sealing ring, realizes the wellbore temperatures measurement by the temperature that records well mud place.Yet because probe all adopts metal material to make with matrix, and the heat conductivility of metal is relatively good, cause the mutual heat transmission between temp probe and the matrix to be accelerated, make the temperature-sensing element in the probe influenced greatly by substrate temperature, cause the mud temperature that records inaccurate.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of wellbore temperatures measuring probe, this measuring probe transmits by the mutual heat of acquiring the extremely slow nonmetals of thermal conductivity and stop or slowing down between probe and the matrix, and then to overcome the existing inaccurate problem of measuring probe thermometric.
For solving above-mentioned technical problem, the present invention takes the technical scheme that solves as follows:
A kind of wellbore temperatures measuring probe comprises matrix and probe, is provided with sealing ring between between probe mounting portion and the matrix, it is characterized in that: also be provided with jacket between probe mounting portion and matrix.
Above-mentioned jacket is partially submerged in the matrix, and the periphery of this embedded part is provided with " O " RunddichtringO.
The above-mentioned periphery that is positioned at the jacket of matrix outside is provided with cannelure, and the cannelure of a side is provided with and the slot to make way of popping one's head in and communicating, and slot to make way is embedded with pressing plate.
Above-mentioned pressing plate by screw on the matrix inner face.
Above-mentioned jacket adopts the slow nonmetals of thermal conductivity to make.
The present invention has the following advantages and effect with respect to prior art:
1, by the jacket that the extremely slow nonmetals of heat conduction are made is set between probe and matrix, when measuring, the heat of matrix is when temp probe transmits, owing to be subjected to the influence of the jacket of midfeather, heat conduction is extremely slow, so be subjected to the influence of substrate temperature minimum during the temp probe thermometric, the measured temperature of temp probe is exactly the true temperature of mud;
2, by " O " RunddichtringO is set between jacket and matrix, be provided with on the jacket itself and probe are fixed on compressing tablet on the matrix, rely on the frictional force of " O " RunddichtringO and fixedly the make probe and the jacket of packing into of compressing tablet to be difficult for deviating from, guarantee to install firmly;
3, offer cannelure by periphery, conveniently realize removing and installing of temperature probe, use efficient and convenient at the jacket of matrix outside.
Description of drawings:
Fig. 1 is a user mode partial structurtes schematic diagram of the present invention.
Each label is represented successively among the figure:
1-mud, 2-probe, 3-" O " RunddichtringO, 4-jacket, 5-matrix, 6-silicone oil, 7-sealing ring, 8-compressing tablet, 9-screw, 10-pad, 11-cannelure, 12-slot to make way.
The specific embodiment:
Referring to Fig. 1, wellbore temperatures measuring probe of the present invention comprises probe 2, matrix 5, sealing ring 3 and jacket 4,2 installation portions of popping one's head in embed in the matrix 5, sealing ring 3 is nested in probe 2 outsides, sheathed jacket 4 on the periphery of probe 2 installation portions that embed matrix 5, jacket 4 adopt the slow nonmetals of thermal conductivity to make; Jacket 4 is partially submerged in the matrix 5, its be between probe 2 and the matrix 5 with stop and slow down pop one's head in 2 and matrix 5 between the heat transmission.The periphery that embeds part in the matrix 5 at jacket 4 is provided with " O " RunddichtringO 3, and jacket 4 relies on the frictional force between " O " RunddichtringO 3 and the matrix 5 to prevent to deviate from from matrix 5.In order to make jacket 4 easy accessibility, be provided with cannelure 11 in the periphery of the jacket 4 that is positioned at matrix 5 outsides, the groove basal plane of cannelure 11 contacts mud 1 place with matrix 5 end basal plane flushes.For better fixedly jacket 4, on the cannelure 11 of a side, offer and 2 slots to make way that communicate 12 of popping one's head in, slot to make way 12 groove basal planes flush with the matrix 5 inner step surfaces that contact the end basal plane at mud 1 place and the middle part of popping one's head in, three basal planes that flush are provided with pressing plate 8, pressing plate 8 one ends are pressed on the step surface at probe 2 middle parts after embedding slot to make way 12 and stretching out slot to make way 12, the other end is fixed on the matrix 5 inner end basal planes by screw 9 and pad 10, thereby jacket 4 and probe 2 effectively are fixed in the matrix 5.
The jacket 4 that the present invention makes by the extremely slow nonmetals of alternating floor heat conduction between probe 2 and matrix 5.When test mud 1 temperature, the heat of mud 1 is by the metal shell of probe 2, be passed to the temperature-sensing element in the probe 2 very soon, and this moment matrix 5 heat when probe 2 transmits, owing to be subjected to the obstruct of the jacket 4 of midfeather, heat conduction is extremely slow, is subjected to matrix 5 Temperature Influence minimum when making probe 2 thermometrics, and the 2 measured temperature of popping one's head in are exactly the true temperature of mud 1.
