千米桥潜山凝析气藏工艺难点及对策

千米桥潜山是我国近年来在陆上发现的大型碳酸盐岩潜山凝析气藏 ,是CNPC1999年度重大勘探发现之一 ,它的成功开发将在很大程度上缓解京津及华北地区工业和居民生活用气的紧张形势。虽然通过前期的钻探及试采评价 ,取得了许多的重要成果及认识 ,但由于潜山内幕的复杂性、储层高温及存在腐蚀性流体等特殊情况 ,使其开发成为了世界性难题 ,工艺仍面临许多难点。试图在分析评价其储层特征、工艺现状及难点的基础上 ,从工艺配套的角度对开采工艺技术思路提出一些探索性意见 ,为有关专家下步进行深入研究提供一些参考。

TECHNOLOGICAL PUZZLER AND STRATEGY ON BURIED HILL CONDENSATE GAS RESERVOIR IN QIANMIQIAO

Qianmiqiao buried hill is large-scaling retardace carbonate buried hill condensate gas reservoir which is discovered on land in recent year in out country as well as is one of the most significant exploring discovery in 1999 CNPC, its successful exploitation would mitigate a situation in short supply which is inhabitant daily life gas using of both Beijing, Tianjin and North China region to a great extent, though gained various important fruits and recognitions by means of preliminary explorative during and appraisement on test production, but due to such special conditions in buried hill inner as inner complexity, reserves with high temperature and fluid with corrosiveness, make the exploitation having became world's puzzler,so technology is confronted with puzzling point.
