Abstract:

Abstract Determining optimum well location for Horizontal well in bottom-water reservoir is the key to keep high and steady production and prolong producing time without water. Using mirror effect and superposition principle of potential function, this paper derives the potential function at arbitrary point in reservoir and acquires the potential difference in horizontal wellbore and production equation of the well. Then, the factors affecting production, critical production and water breakthrough time is studied and the optimum well location for horizontal well in bottom-water reservoir is acquired. It provides the theory base for reasonably developing bottom- water reservoir with horizontal well.

Key words: bottom - water reservoir, horizontal well, critical production, water breakthrough time
