Separate Layer Production and Water Injection Technology Developed in Daqing Oil Field

LiuHe

Abstract

Effects of separate layer production and water injection With the improvement of geological research and development degree, the requirements to water injection are also higher than ever before. The development of water injection technology in Daqing oilfield experienced the following four stages: (1) Commingled water injection, (2)concentric water injection, (3) eccentric water injection, and (4) integrated water injection.Through the above improvements, the development technology improved quickly.
