L block injection-production system adjustment method optimization

摘要

Oilfield development initial stage, people tend to use more sparse well pattern development, production capacity better horizon, reserves were concentrated, inadequate reserves producing remaining oil. In oilfield entered the later period of high water cut development stage, well pattern infilling occupies the important status in production management, and to a large extent determines the production scale of middle and later periods of the oilfield, fixed number of year of exploitation, the final recovery efficiency and economic benefit of oil field. Early L block by 300 m by 300 m spacing against nine points injection pattern, water and residual oil distribution in the oil field development is bound to be late to adjust the encryption pattern, in order to L blocks to determine reasonable well pattern adjustment methods, studies the impact on the development effect of the infilled adjustment of, on the basis of combining economic evaluation, determine the reasonable way of adjustment.
