碳酸盐岩凝析气藏动态综合描述新方法

碳酸盐岩凝析气藏具有极强的非均质性，单纯采用一种方法认识油气藏非常困难。提出了结合静态地质资料认识，充分利用大量的生产动态数据和短时高精度的压力不稳定试井数据，以产量不稳定分析、试井分析以及物质平衡分析方法为手段，对油气藏储层进行动态综合描述。3种方法有机结合、互相约束，使解释结果更加可靠。通过塔里木盆地某碳酸盐岩凝析气藏的动态描述研究，建立了3类井的动态描述识别典型图版，认为该碳酸盐岩凝析气藏储层渗透率、单井控制储量差异较大。 

New Method of an Integrated Dynamic Characterization of Carbonate Gas Condensate Reservoirs

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.
