沙埝南－花庄地区低渗透油藏有效开发技术研究

Study on effective development techniques of low permeability reservoirs in South Shanian - Huazhuang area

沙埝南－花庄地区是江苏油田近年来滚动勘探开发的重点区带，阜三段油藏具有含断块多、含油层数多且薄、合油面积小、埋藏深度大、低－特低渗透和产能低的特点，开发难度大。为有效开发此类油藏，对已发现油藏进行综合评价和开发潜力分析，筛选出近期具有开发潜力的区块，同时开展低渗透油藏的有效开发技术政策的理论研究。研究结果表明，花17断块成藏条件优越，具有开发潜力，为此制定出了有效的开发技术政策，取得了较好的开发效果。

South Shanian - Huazhuang area is an important rolling prospecting and development area of Jiangsu oil field in recent years. There are a lot of oil-bearing blocks at the reservoirs of E1f3, but thin oil-beating formations, small area, buried deep, low-permeability and quite low permeability and low productivity, so it is difficult to develop .To develop this kind of oil deposit effectively, the quality synthetic evaluation and the development potential analysis have been carried out for the discovered oil deposit, the blocks which have development potential in the near future also have been selected. At the same time, the technology theory research about the low-permeability reservoirs how to be developed effectively has been carried out. The research results indicated the Hua 17 fault block has excellent formation conditions, for which an effective technical program were worked out ,finally a better development result has been achieved
