低渗透砂岩石油运移及成藏特征模拟实验
2.
Based on the comprehensive geological study of Niu-20, Chun-41, Zhuang-74 and Daluhu low-permeability sandstone oil pools, the research content and method of the geological model on the reservoir heterogeneity of low-permeability sendstone oil pools in Shengli oil district were sumarized systematically in this paper.
该文在牛20、纯41、桩74、大芦湖等低渗透砂岩油藏地质综合研究的基础上,系统总结了胜利油区低渗透砂岩油藏储层非均质地质模型的研究内容和方法。
3) low permeability sandstone
低渗透砂岩
1.
Threshold pressure gradient of low permeability sandstone;
低渗透砂岩渗流启动压力梯度
2.
The poor producing degree and the economic benefit of the low permeability sandstone by vague injection-production is caused by changeful sedimentary microfacies and high intra-layer and plane heterogeneity in whole oil reservoir set.
针对陕北低渗透砂岩小油田因沉积微相多变,层内和层间非均质性强,整个油层组笼统注采开发采出程度低以及经济效益差等现状,通过对顺宁长12油藏充分利用岩芯分析和测井曲线等基础地质资料,加强沉积微相研究,开展油藏小层精细划分对比及小层砂体连通性分析,明确了主要注采小层在空间上的展布规律,为优化注水开发方案和选用先进注采配套工艺技术措施提供了比笼统注采更为精细的开发地质依据。
3.
The structural fractures in fractured low permeability sandstone reservoirs have great effect on displacement efficiency.
裂缝性低渗透砂岩油层中的构造裂缝对驱油效率有明显影响。
6) Low and low-middle porosity

补充资料：低渗溶液
低渗溶液
hypotonic solution
低于人血浆渗透压的溶液。人血浆渗透压为0.71kPa。通常以此为标准来衡量溶液的渗透压，低于此标准的溶液被称为低渗溶液。主要用于高渗性脱水的病人。
