Analysis Of Injection In Kawaguchi Oilfield

Kawaguchi Yanchang Oilfield field is currently an important oil-producing region, and long6main reservoir for the oil producing reservoir section Kawaguchi, but long-6reservoirs are low permeability, low pressure reservoir, but reservoir thickness, shallow, dense rock, flow ability, well productivity is low. To improve the oil recovery and oil fields, oil fields already on the long Kawaguchi6major oil producing reservoirs in the group conducted a61-bit long artificial fracturing water development, and achieved better development results. In the experience, theory and advanced technology under the guidance of long6after their well water reservoir fracturing oil production decline is slow, so that some low-yield oil wells has improved, water spread area, flooding effect, higher oil recovery, water injection to achieve significant results. But with the development of the water, reservoir characteristics and water movement of the increasing complexity of many development problems and contradictions exposed, flooding effect is reduced, oil production increased water speed, water promote fast, well water channeling and flooding intensified. Therefore, the need for an integrated reservoir geological studies, based on the water in this Analysis, the production as soon as possible to identify the existence of theoretical and technical problems, study effective integrated governance program.
