Abstract
The utility model relates to an anti-high temperature during drilling well pressure temperature testing tool, which solves the problem that a during drilling well pressure temperature testing tool of the existing deep-well high temperature stratum is not suitable for a high temperature. The utility model is characterized in that the upper end of a damping device (2) is fixed by nuts (3), and the lower end of an anti-high temperature device assembly (1) is arranged on an anti-high temperature sealing transfer device (4) on a drilling collar body (5) by threads. The tool can realize the real-time, accurate and automatic testing function of a deep-well during drilling well pressure temperature in a petroleum drilling process, particularly the accurate test of during drilling well pressure temperature datum in deep-well under-balanced drilling wells, gas drilling wells and foam drilling wells.
Description
Technical field:
The utility model relates to oil drilling with boring with bottom pressure temperature test instrument, belongs to high temperature resistance with drilling well downforce temperature test instrument.
Background technology:
At present, in oil drilling, can have much with the instrument that creeps into capable downhole testing, they are sent to ground by wired mode or wireless transmission form, by software by professional's acquisition data of decoding, but many testing tools cause and accept data owing to adapting to down-hole high temperature, mistake appears in transfer of data or signal when being decoded by software, also may cause the damage of testing tool, accidents such as signal interruption appear, though developed the sampling instrument of bottom pressure in the drilling well now, but adaptive temperature is lower, cause the damage of measuring apparatus easily, especially can't carry out measuring while drilling to the down-hole pressure temperature for the deep-well high-temperature stratum, therefore operation brings very big difficulty to petroleum exploration and development.
The utility model content:
In order to overcome the problem of existing deep-well high-temperature stratum with drilling well downforce temperature test instrument incompatibility high temperature.The utility model provides a kind of high temperature resistance with drilling well downforce temperature test instrument, and this instrument can realize in the Process of Oil Well Drilling that deep-well high temperature is with real-time, the accurate and autorun of drilling well downforce temperature.
Technical solution adopted in the utility model is: this high temperature resistance comprises high temperature resistance instrument assembly, damping device and drill collar body with drilling well downforce temperature test instrument, high temperature resistance instrument assembly and damping device place in the drill collar body, the damping device upper end is fixed with nut, and the lower end of high temperature resistance instrument assembly seals on the transfer device by the high temperature resistance that screw thread is installed on the drill collar body.
The beneficial effects of the utility model are: because this high temperature resistance is with drilling well downforce temperature test instrument, be directly installed on the drill string, and the lower end of high temperature resistance instrument assembly is fixed by the sealing transfer device, can realize managing the function of sealing under inside and outside 170 ℃ of hot conditions, anti-blocking and Data transmission.This instrument can be realized real-time, the accurate and autorun of Process of Oil Well Drilling middle-deep well with drilling well downforce temperature.Especially in deep-well under balance pressure drilling, gas and the foam drilling with the accurate test of drilling well downforce temperature data.
Description of drawings:
Fig. 1 is that structure of the present utility model is partly cutd open figure.
1-high temperature resistance instrument assembly among the figure, 2-damping device, 3-nut, 4-high temperature resistance sealing transfer device, 5-drill collar body.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, a kind of high temperature resistance is with drilling well downforce temperature test instrument, comprise high temperature resistance instrument assembly 1, damping device 2 and drill collar body 5, high temperature resistance instrument assembly 1 and damping device 2 place in the drill collar body 5, damping device 2 upper ends are fixing with nut 3, and the lower end of high temperature resistance instrument assembly 1 seals on the transfer device 4 by the high temperature resistance that screw thread is installed on the drill collar body 5.
In actual use, this high temperature resistance is with drilling well downforce temperature test instrument, be directly installed on the drill string, with drill string G.I.H together, data by 1 pair of deep-well annular space of high temperature resistance instrument assembly high temperature are tested, high temperature resistance sealing transfer device 4 can realize managing the function of inside and outside 170 degree hot conditions lower seals, anti-blocking and Data transmission, and damping device 2 effectively reduces the vibrations of drill string, has guaranteed the application life of high temperature resistance instrument assembly 1.This instrument can be realized real-time, the accurate and autorun of Process of Oil Well Drilling middle-deep well with drilling well downforce temperature.Especially in deep-well under balance pressure drilling, gas and the foam drilling with the accurate test of drilling well downforce temperature data.
