Abstract
The utility model relates to a temperature and pressure simultaneously measuring instrument. The steam huff and puff method is adopted to exploit petroleum, the hot dynamic situation under well is required to be mastered at any time, but currently the instrument which can roundly and accurately measure the hot dynamic situation under well does not exist. The temperature and pressure simultaneously measuring instrument of the utility model is composed of four parts; a temperature sensing part and recording system thereof, a pressure sensing part and recording system thereof, a time controlling part, and a high-temperature sealing member and shell. The temperature and pressure simultaneously measuring instrument can simultaneously measure the temperature and pressure changes of each layer position under well during once operation, which not only makes the measuring processes simplified, but the temp. And pressure simultaneously measuring instrument can obtain the mutually corresponding precise measuring data of temp. And pressure; the success rate is a hundred percent.
Description
The utility model relates to the instrument of downhole testing in a kind of petroleum works, and it can once be gone into the well and measure the variation of the temperature and pressure of the saturated vapour of each layer position in the thermal recovery steamed well simultaneously.
Carrying out oil exploitation with thermal methods, is a new technology, in order to control steam injection speed and to annotate the vapour time, must grasp the hot current intelligence in down-hole at any time, measures the variation of the saturated-steam temperature and the pressure that are injected into the down-hole.At present, the appliance requires of domestic use is gone into the well for twice and is recorded one group of data, and Measuring Time differed 3 to 4 hours, and the gained parameter is difficult to corresponding mutually, brings difficulty for the analysis of the hot current intelligence in down-hole.U.S. GRC Corp. adopts the thermometer (similar clinical thermometer) that installs one 10 centimeter length, 700 mercurys in the bottom of pressure-measuring device additional to come temperature and pressure under the measuring well, but the temperature of measuring so only is the maximum temperature of down-hole, can not determine corresponding relation with pressure and layer position, thereby can only reference, can not be as the exploitation foundation.
The purpose of this utility model is to propose the measuring instrument that a kind of one-stop operation changes with regard to each layer position saturated-steam temperature and pressure under the energy while measuring well.
Measuring instrument of the present utility model is made up of four parts.That is: TEMP part and register system thereof, pressure sensing part and register system, time control section and elevated-temperature seal part and housing.The sensing element of TEMP part turns to helix by the 5J25 thermosensitive bimetal, the upper end is a fixed end, the lower end is a free end, free end and hollow shaft join, the hollow shaft other end joins by bellows and thermograph pen, and when variations in temperature, free end rotates corresponding angle with variation of temperature, and drive the thermograph pen by hollow shaft and bellows and rotate synchronously, so write down variation of temperature on the card of recording pen in record cylinder.The sensing element of pressure sensing part is processed into helical Bourdon tube with the accurate constant modulus alloy of 3YC10, the lower end is a fixed end, the upper end is a free end, free end and power transmission shaft join, power transmission shaft passes the hollow shaft of temperature indicating crayon, join by bellows and pressure record pen, when pressure changes, the free end of helical Bourdon tube rotates corresponding angle thereupon, and drive the pressure record pen by power transmission shaft and bellows and rotate synchronously, thereby the pressure record pen is write down the variation of pressure on the same card sheet of record temperature.Because the power transmission shaft of thermograph pen is a hollow shaft, the power transmission shaft of pressure record pen passes hollow shaft and drives pen force work, so be independent of each other during work.The time control section is made up of high temperature clock, clutch, drive screw, nut, record cylinder stroke guide rod, record cylinder.In the record temperature, clock is made linear uniform motion from top to bottom by above-mentioned running part, targeting part, drive record cylinder.On the card in record cylinder, being drawn respectively with the Measuring Time by thermograph pen and pressure record pen is abscissa like this, is changed to two curves of ordinate with variations in temperature and pressure.According to survey layer position and the corresponding relation of time, just can obtain the hot current intelligence of each relevant layer position, down-hole again.The seal at loading and unloading position is made ring-type by soft graphite in the measuring instrument, during assembling, reaches and sealing with the method for crimp.
Measuring instrument of the present utility model has solved the hot dynamic data in petroleum thermal production well down-hole and has measured inaccurate problem, simplified measuring process, one-stop operation just can be surveyed the data that full down-hole each layer position saturated-steam temperature and pressure change, the gained data accurately and reliably, in the commercial Application, the actual measurement success rate reaches 100%.
The embodiment given below in conjunction with accompanying drawing further describes the utility model.
Accompanying drawing is a structure chart of measuring temperature and pressure-measuring device simultaneously.
Measure 1800 millimeters of the measuring instrument total lengths of temperature and pressure in the time of among the embodiment, 36 millimeters of external diameter φ, form by following 23 parts and part: meter case (1), loading and unloading position seal (15), (22), special-purpose time clock machine (2), clutch (3) drive screw nut (4), (6), record backrest (5), record backrest cover plate (7), record cylinder stroke guide rod (8), record cylinder (9), pressure record pen (10), thermograph pen (11), recording card (12), temperature valuator (13), (14), pressure power transmission shaft (16), temperature-sensing element (device) (17), temperature Hollow Transmission Shafts (18), pressure-sensing device (19), pressure axle bed (20), (21), strainer (23).
Temperature-sensing element (device) of measuring instrument (17) and pressure-sensing device (19) are made by 5J25 heat-sensitive duplex metal material and the accurate constant modulus alloy of 3YC10 respectively.It is universal drive shaft that thermograph pen (11) and pressure record pen (10) all adopt bellows.Seal (15), (22) at loading and unloading position all adopt soft graphite to be processed into ring, force down sealing during assembling, can bear the HTHP of down-hole.
The measuring instrument of measuring temperature and pressure simultaneously is work like this, before going into the well, gives full string on the high temperature clock, and mentions clutch, and the pull hook of leaving behind then makes thermograph pen and pressure record pen enter duty.Instrument is erected, mention record cylinder and drawn baseline, involutory clock clutch installs shell with special tool, and this moment, tester was started working.With steel wire instrument is arrived the down-hole down, test.After the test, tester is mentioned aboveground, when treating that temperature drops to below 100 ℃, taken out record-paper with special tool.
