摘　　要：为了改善海相砂岩高含水油田、裂缝性油气田、高温高压气田等海上复杂油气田的开发效果,开展了全过程开发策略的专题研究。通过研究,明确了海上复杂油气田投产上产、稳产、整体加密与综合调整以及产量递减等4个开发阶段,分析了全过程中不同开发阶段的生产特征、主要矛盾、开发应用策略和主要方式,提出海相砂岩高含水油田的攻关方向主要是水平井堵水技术和控水技术,裂缝性油藏的攻关方向主要是机械或化学堵水控水技术和分支井技术,高温高压气藏的攻关方向主要是工艺优化技术、材料防腐技术、温压监测技术和井下流量监测技术。通过攻关实践,在整体加密与综合调整的基础上,海相砂岩高含水油田、裂缝性油气田、高温高压气田的采收率可分别再提高3~5个百分点、2个百分点、2~5个百分点。In order to improve the development effect of marine sandstone oilfield with high water cut,fractured oil and gas field,high-temperature and high-pressure gas field,the development strategy in overall process was studied.Through research,the development of the offshore complex oil and gas fields may be divided into four stages ：production,stable yield,whole infill and comprehensive adjustment,and production decline.The production features,principal contradiction,development strategy and main pattern at different stages were analyzed.The technology of water plugging and water control by the horizontal well should be re-searched for the marine sandstone oilfield with high water cut.The technology of mechanical or chemical water plugging and controlling and multilateral well should be researched for the fractured oil reservoir.The technology of technical optimization,anti-corrosion material,temperature and pressure monitoring and downhole flow monitoring should be researched for the high-temperature and high-pressure gas reservoir.After the overall pattern infill and comprehensive adjustment,the final recovery factor of the marine sandstone oilfield with high water cut,fractured oil and gas field,and high-temperature and high-pressure gas field can be enhanced by 3-5 pct.,2 pct. and 2-5 pct. respectively.
