摘要
三塘湖盆地火山岩储层中孔、低渗、特低渗特征明显,导流导压能力弱,井筒储集效应大、试油周期长、油层易污染、测试曲线无法拟合定量分析,资料获取率和优质率低,致使大量的地层测试资料不能有效的用于储层评价,无法为下步勘探、储量评价和储层措施改造提供有效依据。通过研究应用等时速率解释评价技术,解决了三塘湖盆地火山岩测试解释评价难题。应用结果表明,该技术完全适应于三塘湖盆地火山岩储层特征分析,深层次的揭示了三塘湖盆地火山岩储层的非均质性特征,为油田经济有效的勘探开发提供了依据。
Volcanic rock reservoir in San Tanghu basin has obvious feature of medium porosity,low permeability and super low permeability,poor flow conductivity and pressure transmitting,great effect of wellbore storage,long cycle of oil testing,easy pollution oil layer,testing curve can not match quantitative analysis,low data acquirement ratio and high quality rate.A great deal of formation testing can not use effectively reservoir evaluation and provide valid basis for nest step exploration,reserve estimate and reservoir measurement.By means of research and application of isochronal rate interpretation evaluation technology,it can solve volcanic rock testing interpretation evaluation problem in San Tanghu basin.Application results show the technology is completely suited for volcanic rock reservoir characteristic analysis in San Tanghu basin, reveal deeply anisotropy feature of volcanic rock reservoir in San Tanghu basin,and provide effectively basis for oilfield exploration and development.
