摘　　要：孔隙度、渗透率参数是理解一个油藏如何产油的重要依据,是最重要的储集层评价参数。常规岩心分析测试耗资高,且有一两个月的较长测试周期,不能满足储层评价及时性要求。针对这些问题,建立了现场快速岩心分析技术,该技术所用设备结构简单、方便运输、测定速度快,设备重复性与稳定性符合行业标准,与实验室对比准确度较高。通过岩石物理现场快速测量分析,快速获取岩心的孔渗参数,对于复杂储层、复杂岩性、高温高压等疑难层的认识有极大帮助,并为现场决策、后续测试作业提供可靠的依据。The porosity and permeability are important basis for understanding how to produce in an oil reservoir, and also are the most im- portant reservoir evaluation parameters. The cost of the conventional core analysis is high, and the test cycle lasts two months. So the con- ventional core analysis can＇ t meet the timeliness requirement of reservoir evaluation, The on-site quick analysis of core technology can solve these problems. The equipments required by this technology are simple, easy to transport, fast to measure, which can meet repeatability and stability industry standards with high accuracy compared with the laboratory tests. The on-site quick analysis of core technology can measure petrophysical parameters quickly including porosity and permeability, which can provide a reliable basis for on-site decision-making and follow-up testing operations for the complex reservoirs, the complex rock, the layer with high temperature and pressure, and other difficult layer.
