Quantitative calculation method of development indexes for layered and directional of production wells(生产井开发指标的分层分方向定量计算方法)

针对注水开发的多层砂岩油藏分层动态分析难度大等问题，在常规井层开发指标计算基础上，结合动、静态劈分方法，综合考虑渗透率、孔隙度、地层系数、含水饱和度、位置系数、措施系数及注水量系数，提出了一种既可将油、水井作为统一整体，又可对小层、方向流动分量开发指标进行定量计算的体现渗流力学本质的方法。用大庆油田N2-O1井组的产液剖面资料进行验证。结果表明，所提方法的计算结果与测量结果吻合度较高，精度平均值达75.11%。用该方法计算开发指标，适用性强，能较真实地反映各小层、各方向的产液...

Compounds of Marine Origin with Possible Applications as Healing Agents

It is well established that marine organisms consist of a great variety of active compounds that appear exclusively in the marine environment while having the ability to be vastly reproduced, irrespective of the existing conditions. As a re...
