摘要
针对涠西南凹陷复杂储层试井解释问题大概划分为储层问题;流体问题;测试问题三大类。探索性提出了一些试井解释方法(低渗透试井、早期试井、PPD诊断曲线、SLPD诊断曲线以及Y函数),并总结归纳了目前涠西南凹陷复杂储层的试井解释方法(主要是针对探井、评价井),同时结合区域资料展开了复杂储层产能评价工作,应用试井解释结果及节点分析方法对该工作的有效性进行了充分的论证。以X1井和X2井为例,介绍了一些探索性的试井解释方法和产能评价工作。
Well test interpretation problem can be divided into three kinds in complicated reservoirs in Weixinan(Southwest Weizhou)Sag,i.e.reservoir,fluid and testing.Several well test interpretation methods,such as well test method in reservoir with low permeability,well test method at early time,PPD diagnosis curve method and Y-function method etc.,are probed,and current used well test methods mainly for exploration wells and appraisal wells in complicated reservoirs in Weixinan Sag are summarized.Besides,deliverability evaluation for complicated reservoirs is conducted with combination of regional geological information,the effect of which is estimated by well test interpretation results and nodal analysis.This paper introduces these probed well test interpretation and deliverability evaluation methods.
