Title:
WATER INJECTION METHOD IN RECHARGE METHOD
Document Type and Number:
Japanese Patent JP2005330763
Kind Code:
A
Abstract:
To recover water injection capacity while continuing water injection from a condensate well and to increase the total amount of water injection compared with a conventional method.
In this water injection method in a water recharge method for injecting water into the ground through a pipe body provided underground, the injection pressure of injected water is allowed to temporally fluctuate to form cleavage in the ground to inject water. When water injection capacity is lowered during a water injection period, the injection pressure of injected water is allowed to temporally fluctuate to form cleavage in the ground to inject water, thus recovering water injection capacity.
