Abstract:

LH4 - 1 Oilfield is a heavy oil field developed from the basis of the bioherm of Miocene Zhujiang Formation. Biohermal limestone is a kind of massive carbonate reservoir rock formed in marine environment. Based on the reservoir distribution studied with the genesis of the reef limestone and seismic attribute, the geologic modelings of block geologic body and vertical aggraded clastic reservoir were indicated. A set of technical methods for geologic modeling suitable to massive reservoir was studied. These methods have proved a good effect.

Key words: cementation , retention processes , sandstone reservoir , reservoir quality prediction
