摘要
孤岛油田和孤东油田为疏松砂岩油藏 ,已进入开发后期 ,油水井套管损坏严重。统计了两油田的套管损坏位置分布特点和损坏类型。并从注水、出砂、地层滑移、固井、采油及井下作业等方面分析了套管损坏机理 。
Gudao and Gudong Oilfields,which are at the late stage of development, are composed of unconsolidated sandstone reservoirs, which results serious casing failures. The statistics of location distribution and type of casing failures are made in the oilfields. The failure mechanism of water flooding, sand production, formation gliding, cementing, oil production and borehole operation is analyzed, which provides basis for taking preventive measures.
