提高中高含水期油井压裂经济效益的方法

为提高葡北油田中高含水期油井压裂经济效益，合理选择压裂井层尤为重要。应用水驱特征曲线预测出油井压裂前可采储量，从而计算出剩余可采储量及可采储量采出程度，通过绘制油井压裂前剩余可采储量及可采储量采出程度与油井压裂后所创经济效益之间关系曲线，寻找出相关规律，进行优选压裂井，再根据精细地质研究成果，在剩余油富集区选择具体压裂层位。经实际应用，取得了较好效果，提高了油井压裂方案符合率，提高了经济效益，进而总结出一套适合葡北油田中高含水期油井压裂选井选层方法，对今后进一步搞好油井压裂增产工作具有指导意义。

New strategies for separations through reactions

Separations through reactions can provide reliable and economically viable alternatives to established methods of separation, particularly for close boiling substances. New strategies in ‘Dissociation Extraction’ and ‘Dissociation Extractive Crystallization’ for separation of close boiling acidic/basic mixtures have been highlighted. Separations with aqueous solutions of hydrotrope and aqueous micellar solutions have been brought out. Separations by membranes with facilitated transport is potentially attractive. This paper is dedicated to Dr L K Doraiswamy on his sixtieth birthday.     

Bioactive compounds in rye flours with different extraction rates

Rye flours with extraction rate of 100% (wholemeal flour), 95% (brown flour), 90% (brown flour) and 70% (light flour) were prepared in order to study the relation between flour extraction rates and content of bioactive compounds. The following compounds were analysed: total phenolic compounds (TPC), total flavonoids (TF), inositol hexaphosphate (IP6), reduced (GSH) and oxidized (GSSG) glutathione, tocopherols (T) and tocotrienols (T3). The reduced/oxidized glutathione status (GSH/GSSG) of the flours was examined as a potential index of flour resistance against oxidative stress. The following observations were made in relation to the flour extraction rates and bioactive compounds contents: (a) milling process caused decrease in content in TPC, TF, IP6, GSH and GSSG, T and T3, (b) the most resistant against oxidation processes were suggested a brown flours, then light and finally wholemeal flour, (c) the ratio of tocotrienols to tocopherols (T3/T) was the highest in rye flours with extraction rate of 100–90% whereas light flour was the poorest source of tocopherols and tocotrienols. The provided data support current trend to increase number of rye products from wholemeal or brown flours.
