Application of de-filtration technique in fracturing of Fulin Sag;

Analysis of the subsag types and corresponding origins demonstrate that only the types of those oil-rich or sub-oil-rich subsags can be expected to have potentials for accumulating large or medium size oil fields.

The five key factors that are responsible for PY4-2 oil pool include rich source kitchen,marginal fault of sag, assemblage of reservoir and seal of delta front sandstone and mudstone,compressing structure as well as appropriate time of oil migration and trap formation.
