Abstract

Carbonate reservoir is extremely heterogeneous,so it is difficult to describe this kind of reservoirs only using one simple method.This article presents a method of dynamic characterization for carbonate reservoirs,which mainly use production analysis,well test analysis and material balance analysis in combination with geological understanding.The technology can be fully integrated with the long-term low accuracy data of dynamic production and short-term high-precision data of transient well testing,in order to correctly evaluate the characteristics of the reservoir around the well.These three methods can be constrained and integrated with each other.Take a carbonate reservoir in Tarim Basin as an example to elaborate the details of this method.Three types of wells are classified based on the type curves characteristics,and the evaluation results show the permeability and dynamic reserves of single wells are very different.

Key words： Carbonate; Dynamic characterization; Production analysis; Well test interpretation; Material balance analysis
