摘　　要：特高含水期是油田开发的重要阶段,采出程度是编制油田开发调整方案的重要指标,因此特高含水期采出程度的测算对油田开发具有重要意义.在发展完善水驱曲线、相渗曲线计算采出程度方法的基础上,综合利用开发动态数据、室内实验数据、矿场试验数据,计算得出喇、萨、杏油田分类油层、分开发区特高含水期采出程度为8％ ～ 10％.明确了喇、萨、杏油田剩余储量潜力,为特高含水期开发调整提供了可靠依据.Extra-high watercut period is the important stage of an oilfield development, the produced recovery is the key index for the compilation of the oilfield development adjustment program, therefore the test and calculation of the recovery at this period possesses great significance for the oilfield development. The calculating methods of the produced recovery by the waterflooding and relative permeability curves are improved and perfected, by means of the integration of the development performance data, indoor experimental and field test data, 8% -10% pro- duced recoveries for the sorted oil layers and separated developing blocks in Lasaxing Oilfields at extra-high watercut period are calculated. Just because of the achievements stated above, the remained reserve potentials of the oilfields are clarified, thus the reliable evidences for the development adjustment at the extra-high watereut period are presented.
