Abstract

In order to clarify the influence of the instrument’s own drag on the temperature distribution in the horizontal gas wellbore in temperature logging. By constructing an indoor gas-liquid two-phase horizontal tube flow platform, the effects of the drag speed of the instrument on the temperature distribution in the wellbore were studied in the single-phase gas and gas-liquid two phases. In addition, during the process of instrument dragging, the influence of different perforation cluster opening methods and wellbore inclination on temperature distribution was also studied. The results show that the temperature fluctuation is reduced at higher drag speeds; Under a certain flow rate, the smaller the number of openings, the greater the influence of the instrument dragging inside the tube on the temperature distribution inside the tube; When the inclination angle is −5°, the drag of the instrument in the tube interferes greatly with the temperature distribution. When the inclination angle is 5°, the drag of the instrument in the tube has less interference with the temperature distribution. This study provides more reference for the future temperature calculation model of horizontal wellbore and has important research significance.
