摘要
低渗透油藏试井测试过程中,压力降落或恢复速度非常慢,试井数据一般只测试到早期段,导致试井解释困难和结果多解性。研究在试井解释方法理论基础上,提出了时空试井解释方法,确定了试井解释结果可靠性判别标准,并以国内典型超低渗透油藏为例,利用井在不同时期、不同空间的试井测试数据,结合油藏的地质认识和开发现状,对试井解释结果进行分析,确定了合理试井解释模型和解释结果,该方法可为低渗透油藏试井解释提供技术参考。
It is difficult to detect the radial flow during pressure built-up period for the low permeability reservoirs. This brings much problem for well test interpretation. Taking the typical low permeability reservoirs for example,using the well test data in different periods of different space well test,combing with the reservoir geological data and the production history,and a new well testing analysis method is proposed. The method can determine the reasonable well test interpretation model,and get the reliable results. It can provide the technical reference for the low permeability reservoir well test interpretation.
