After the Lamadian oilfield enters the development period of ultra-high water cut, the third type oil layer will be in the stage of water flooding development in the medium and long term in the future. By recombining oillayers and rebuilding the well network, it is possible to better control the difference of oil layers, slowing plane, inter-layer and intra-layer contradictions, improving the development effect of multi oillayers sandstone reservoir in extra-high water cut period. This paper uses the subdivision of water-driven oillayers, recombining oillayers, many datas of field test, comprehensive analysising and studying the third type oil layer (Gao I6 and below), providing technical support for the adjustment of the well pattern network of the third type of oillayer development in the future, and forming an operational development model for the subdivision of water-driven oillayers, the reconstruction of well pattern in the development stage in ultra-high water cut.
