Abstract

Summary

Horizontal wells is effective method of oil and gas development. One of the important tasks is production control of horizontal wells. At this case, interpretation of logging data is a very difficult task. First problem is uneven trajectory because horizontal well typically have ascending, horizontal and descending sections, in which the phase velocity and fluid holdup is changed (in this paper consider oil and water stratified flows). Secondly, in the ascending section of horizontal well can occurs countercurrent flow. Thirdly, the heat exchange between fluid phases and the surrounding rocks take place and it influence on temperature distribution.

The paper discusses a mathematical model for the calculation of fluids holdup, velocities and temperature distribution along horizontal wells with countercurrent flow. The calculation results of fluids holdup, velocities and temperature distribution are shown in paper and analysis of countercurrent flow influence are made.
