Abstract

The water cut of some oilfield increased rapidly in Orinoco heavy oil belt in Venezuela; the most important key is that the parts of reservoir invaded by low-salinity meteoritic water are called meteoritic flushed zone. The paper investigated the possible causes of the flushed zone, based on the identified flushed zone in P oilfield, and three methods used to identify flushed zone were summarized (conventional logging, NMR, and other test data). Different development strategies were made according to different contact relationship between the flushed zone and reservoir. Based on the well logging identify methods for the meteoritic flushed zone, all the wells in the P oilfield were reprocessed, the development strategies also was adjusted, and the comprehensive water production rate of oilfield was decreased. Proved that the meteoritic flushed zone identify methods and oilfield development strategies adjusted methods are possible. The well logging identify methods for the meteoritic flushed zone provide important technical support for Orinoco heavy belt; also the oilfield development strategies adjusted methods provide a significant reference for the other assets on the Orinoco heavy oil belt.
