摘　　要：海上边底水油田在生产过程中含水上升快,短期可达90%以上,而常规找水、堵水技术不能满足现阶段要求。为降低含水率,提高单井产能,研制了适用于海上油田的稳油控水技术,该技术集控水、稳油、防砂为一体,可对水平井进行分段开采,减缓水锥突进,达到稳油控水目的。该技术现场成功实施4口井,措施后日产油量由47 m^3/d升至53 m^3/d,含水率由95%降至93%,取得了较好的稳油控水效果。该项新技术的成功应用,解决了海上油田含水上升过快的问题,延长了油井稳产时间,提高了单井产能,对高含水油田的高效开发具有借鉴意义。The offshore oilfield with edge-bottom aquifer shows a high water-cut increase and the water-cut could reach over 90% in short-term production.However,the conventional aquifer identification and water-blocking technologies cannot meet the current requirements.An oil-maintenance and water-control technology for the offshore oilfield has been developed to reduce the water-cut and enhance well production capacity.The water-control,oil-maintenance and sand control are integrated by this technology.The subdivision production for horizontal well is realized to slow water coning and maintain oil production.After successful application to 4 wells,the daily oil production increases form 47 m^3/d to 53 m^3/d and the water-cut decreases from 95% to 93%,which shows a better performance in oil-maintenance and water-control.Successful application of this new technology improves the rapid water-cut increase in offshore oilfield,extends well production maintenance period and enhance well production capacity,which could provide certain reference for the efficient development of high water-cut oilfields.
