Abstract:

Horizontal well’s reasonable location is the key to keep high and steady production and to prolong producing time without water in edge-water drive reservoir with closed boundary vertically. Using mirror effect and superposition principle of potential function, this paper derives the potential function at arbitrary point in edge-water drive reservoir with closed boundary vertically and acquires the potential difference in horizontal well bore and well’s production equation. Then it researches the factors affecting production, critical production and water break- through time and acquires the optimum well location for horizontal well in edge-water drive reservoir with closed boundary vertically. It provides the theory base for developing reasonably edge-water drive reservoir with closed boundary vertically with horizontal well.

Key words: edge-water drive reservoir, horizontal well, producing rate, water breakthrough time, optimum location
