摘要
苏丹六区项目是CNPC与苏丹政府签订的第一个勘探开发项目,也是中国石油(CNPC)首次在海外独自承担风险、进行大规模油气勘探开发项目。苏丹六区是一个复杂的含油气区块,经过中国石油人的艰苦努力,从2001年开始,在短短的5年时间,在该区块先后共发现七个油田,探明石油地质储量是原作业者的7倍,取得了较好的效益。文中论述了该区块的勘探开发历程与石油地质特征,总结了海外复杂地区风险勘探开发的主要经验:加强地震野外采集与室内处理技术一体化攻关,提高空间采样和覆盖次数,努力提高资料质量;开展石油地质综合研究,针对该区地质特点,加强圈闭优选与断层封闭性评价,快速评价钻探;勘探开发一体化,在评价勘探的同时,开始开发早期方案编制工作;为加速开发已发现的油田,针对六区稠油油田特点,采用“携砂冷采”的方式,通过一年的生产,取得了开发此类油田的经验。
Block 6. located in the Northwest of Muglad Basin, Sudan, is the first exploration & production project signed by CNPC and Sudan government in 1995. Block 6 is a very complicated fault-block oilfield. Since 2001 seven discoveries have been made in North Fula,South Fula, Moga, Naha, Hadida, Shoka, Sufyan etc. within 5 years. This paper discussed three phases of exploration & development and characteristics of petroleum geology in block 6, and summarized the exploration experience and main ways of doing in overseas complicated oilfield: strengthen the study of the integration of field seismic data acquisition and the indoor data processing to improve the data quantity; conduct the comprehensive petroleum geological research to strengthen the optimized selection of the traps and the evaluation of the fault sealing characteristic; Integrating the exploration and the development by preparing the field development plan of the earlier period while carrying out the evaluation prospecting; in order to accelerate the development of the discovered oilfields, the method of cold production with sand has been adopted for one year and the experiences has been made in this type oilfield.
