Description
Technical field:
The utility model relates to a kind of downhole instrument that parameters such as high temperature well downhole temperature, the temperature difference are carried out full well section follow-on test that is used for.
Background technology:
In oil field development and oil well production process, need monitor downhole temperature, so that oil reservoir production is dynamically analyzed and the measure adjustment.At present, there is method of temperature under the multiple testing well at the scene, and wherein DTEM is the another kind of manifestation mode of downhole temperature, more can reflect the variation tendency and the minor variations of downhole temperature, in order to the dynamic change of reflection down-hole.The mode of current the most frequently used test DTEM is the covert calculating of directly carrying out with temperature, can not directly reflect the slight change of downhole temperature.Existing DTEM test is to change by delay circuit survey data is converted to the temperature difference of giving the point-to-point transmission of set a distance by a certain, does not generally have depth correction in the existing temperature measuring device.
The utility model content:
The purpose of this utility model is to provide a kind of downhole temperature variation tendency that can directly reflect to be used for the high temperature DTEM tester of production dynamic analysis, measure adjustment.
The utility model is to realize like this.This kind well temperature tester is made up of heat insulation bottle, battery tube, magnetic localizer, data acquisition board, sensor, heat absorbent, thermometric section, its structure organization relation is as follows: be provided with battery tube, magnetic localizer, data acquisition board, pressure sensor and heat absorbent from top to bottom successively in the heat insulation bottle, the below is connected to the thermometric section, which is provided with pressure port.The parameter of this well temperature tester, test has temperature, pressure and DTEM, wherein the method for testing of temperature, pressure is platinum resistor temperature measuring, the pressure measurement of semiconductor diffusion silicon pressure sensor, the elementary errors test is arranged on the temperature test point 2 points (distance is 400mm) of fixed range, directly recording 2 temperature closes, adopt the position of memory-type magnetic locator detection sleeve pipe or tubing coupling, in order to CD.
The utility model is reasonable in design, reliable operation, utilizing it can directly test high temperature well downhole temperature elementary errors changes, can directly on the elementary errors curve, obviously embody when having temperature fluctuation to change on the down-hole is vertical, can embody according to these and judge the variations in temperature position, amplitude and scope are used for production dynamic analysis and measure adjustment.
Description of drawings:
Accompanying drawing is a general structure schematic diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of heat insulation bottle 1, battery tube 2, magnetic localizer 3, data acquisition board 4, sensor 5, heat absorbent 6, pressure port 7, thermometric section 8.Wherein, heat insulation bottle 1 for one be used for isolated temperature, for instrument test, gather the cylinder that protection is provided.Battery tube 2 is used for holding battery provides electric power for whole instrument cylinder for one.Magnetic localizer 3 adopts the memory-type magnetic locator, is used for detecting the position of sleeve pipe or tubing coupling.Data such as data acquisition board 4 collecting temperatures, pressure, the degree of depth, the temperature difference.Pressure sensor 5 adopts the semiconductor diffusion silicon pressure sensor, and the elementary errors sensor adopts the high sensitivity thermocouple to form paired end points.Heat absorbent 6 is used for absorbing the transmission of heat in the heat insulation bottle of blocking-up, protection power supply apparatus.Thermometric section 8 is provided with pressure port 7, is used for being communicated with external and internal pressure, and external pressure is delivered to instrument internal.
