摘要
布于塔河油田第九区块的AT28井是一口追踪本区烃源和探明盐上、盐下储盖层特征的重要探井。该井针对不同开次不同地层的特性,本井先后采用了聚合物钻井液体系、聚磺钻井液体系、欠饱和盐水聚磺钻井液体系和聚磺防塌钻井液体系。
AT28 well distributed in the ninth blocks of Tahe oilfield is an important exploration well to tracking the hydrocarbon in the region and vertify the feature of reservoir and seal rocks between Yanshang and Yanxia.According to the different spuds in distinct formation characters,polymer drilling fluid system,polysulfide drilling fluid,under-saturated brine system containing polysulfonate and anti sloughing-sulfated polymer drilling fluid system have been adopted in the well successively.
