The Discussion of the B603 Block's Supplement Development SchemeThe Discussion of the B603 Block’s Supplement Development Scheme

To B603 block, the main strata is Guantao group of four sand groups, the reservoir buried deep is 1,004-1,067 m, reservoir lithology is mainly siltstone, reservoir belongs to high porosity and high permeability, and reservoir type is mainly structural lithological reservoir. According to the design of the previous adjustment plan, four wells were drilled in 2010. In order to further improve the producing degree of reserves and recovery factor, the previous adjustment plan was improved. North District, where well control is poor, continued to be expanded to improve the producing degree. And southern district continued to improve well network and enhance ultimate recovery factor.
