摘要
利用渤海水驱砂岩油田80个独立开发单元资料,回归了不同井网密度下的采收率经验公式。结合老区油田递减规律及经济评价方法,推导出了老油田经济井网密度的计算方法。该方法对海上老油田的井网加密具有较强的实用性。
Based on the data of 80 independent development blocks in Bohai water drive oilfield, empirical formula of recovery factor in Bohai oilfield is regressed. Combined with the decline law and economic appraisal method, the calculation method for economical well density of old oilfields is set up, which has strong practicability for well pat-tern infilling in offshore oil field.
