摘　　要：随着油田开发的不断进行,多数老油田进入开发后期,增油潜力日渐降低。一些如低渗、潜山等难动用储量油藏的重要性逐渐凸显。河口地区碳酸盐岩裂缝性油藏储量丰富,更需对该类油藏的开发工艺进行研究与应用。在借鉴国内外同类型油藏开发的基础上,与相关科研院所合作,对富台油田、渤深6块等深层潜山油藏区块的储层发育特征、开采特征进行了研究,着重对开发潜山油藏的主导工艺技术——酸压技术进行了探索,初步形成了适用于河口地区碳酸盐岩裂缝性油藏的酸压工艺,并进行了推广应用,取得了良好效果。通过潜山油藏酸压技术的研究和应用,现场的试验证明,对该类油藏实施多级交替注入复合酸压工艺是成功的,适合河口地区深层潜山油藏的地层特点,该技术满足了高温、深层潜山油藏酸压的要求。With the development of the oilfield,most oilfields come to the phase of production decrease and are hard to increase the production.The storability of some low permeability and buried hill type reservoir will become more important.The effective exploitation of these reservoirs is important for the adjustment of increasing production constitution and the retardation of decreasing.Large reserves exist in the creviced carbonate formation in Hekou.It is necessary to study the exploitation technique of this type of reservoirs.Cooperating with other research institutes and investigating the technique used in the same type of reservoirs,the acid fracturing technique is studied in Futai oilfield and Boshen 6 area after analyzing the characteristics and development history.The application results show that it is effective to the reservoir by alternated injection.It could be used at the temperature between 150℃ and 170℃ and the depth between 3 900 m and 4 600 m,which are satisfied with the demands of the buried hill type reservoir.
