Abstract
In the process of the old oil field exploration, reservoir reconstruction, acidification and extract liquid is a common method of increase production. The reservoir connectivity is a key to the success of increase production. The research are based on the resistance capacity model, put forward the characterization parameters between the injection and production well, use dimensionless injection-production connectivity to identify the well flow channel. The results show that when the dimensionless injection-production connected coefficient greater than 1.1, the formation exist dominant channel. When the dimensionless injection-production connectivity coefficient is between 0.7 and 1.1, the injection-production efficiency is stay normal. When the dimensionless injection-production connectivity coefficient is less than 0.7, the reservoir transformation is require take action to decrease blockage. The research was successfully applied in the K&B oilfield for increase production measures such as fluid extraction, acidification, well group fracturing, etc., and the daily increase of oil in a single well was 272.2 m3. The research have significance guiding for the development of old oil fields.
