In Can 2X1 small fault-block viscous oilreservoir in Jidong Oilfield, reservoir is buried deeply, boundary and bottom water is active.
冀东油田蚕2X1小断块稠油油藏埋藏深、边底水较活跃，为此提出以热采作为该块的开发手段。

The reservoirboundary includes oil-water contact, lithologic boundary and fault limit.
油藏边界主要包括油水界面、岩性边界和断层边界等。

Initial oil saturation is controlled by the reservoirboundary and structural. Parts of the reservoir with high initial water saturation dose not form effective edge and bottom water drive.
