永8复杂断块油藏水平井地质优化设计

永8块为复杂断块油藏，若全部采用直井开发，不但井网密度大、开采时间长，而且直井防砂后产量低，开发效益不明显。水平井开发的可行性论证认为，出砂的复杂断块油藏适合用水平井开发；水平段应与大断层保持一定的距离且位于正韵律油层的中上部。采用直井和水平井相组合的布井方式，可充分发挥直井钻遇油层层数多和水平井与油层接触面积大、产量高的优势，从而提高复杂断块油藏的开发效果。     

中国石油未来油气勘探重点领域分析

根据近几年来的研究认识与勘探成果分析,未来几年中国石油油气勘探主要集中于如下五大重点领域:大面积低渗透岩性油气藏、成熟区复杂隐蔽油气藏、前陆盆地复杂构造油气藏、海相碳酸盐岩油气藏和渤海湾滩海第三系油气藏。

蒙古尼尔金盆地石油地质特征及勘探前景

位于蒙古国中部的尼尔金盆地是一个中生代裂谷盆地，目前仍处于勘探早期。盆地内下白垩统湖相泥岩和纸状页岩具有很强的生油能力，下白垩统的煤系地层及上二叠统-下侏罗统中富含有机质的泥岩和煤层是可能的气源岩；盆地内广泛分布着3套储集层；上侏罗统、下白垩统、上白垩统的泥岩是潜在的盖层；存在多种生储盖组合及远景圈闭类型。通过对石油地质条件的分析，认为尼尔金盆地很可能形成多套含油气层系和多种油气藏类型，推测在盆地中部和南部会有大的油气藏存在。     

Quality of Crude Fish Oil Extracted from Herring Byproducts of Varying States of Freshness

ABSTRACT: Herring byproducts were stored at 2 and 15 °C for up to 72 h. Over time, significant increases of total volatile bases (TVB), histamine, putrescine, cadaverine, and tyramine were detected. However, only tyramine and TVB levels were temperature-dependent. The level of total polyunsaturated fatty acids (PUFAs) was constant. Longer byproducts storage gave rise to an oil with higher levels of free fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and total PUFAs, while fluorescent compounds were lower. A higher storage temperature led to oil higher in α-tocopherol and EPA levels and lower in anisidine value. Surprisingly, the oil with the highest content of PUFAs was not produced from the freshest byproducts, and oil with low oxidation products can be extracted from stored byproducts.

N.m.r. line shape-relaxation correlation analysis of bitumen and oil sands

The first results of the analysis of bitumen and oil sands using the recently developed n.m.r. spingrouping technique are presented. The n.m.r. relaxation experiments were carried out on bitumen, and on natural and dried oil sands samples. The results indicate that the spin-grouping can resolve and quantify several components of the samples studied. The bitumen and bitumen fraction of the oil sands are resolved according to their spin-spin relaxation times into three major groups: solid-like (rigid), solid-like (mobile) and semi-liquid. The water in the oil sands exists in two different environments. Tentatively one environment is assigned to be the bridges between the sand grains, while the other is assigned to be the clay surface. One can conclude that with spin grouping of complex mixtures the decomposition (in which components are resolved according to their dynamic state) is possible. The accuracy of such resolution is of the order of a few per cent.     

文13西块数值模拟研究

中原油田文13西块纵向和平面非均质严重，油水分布规律性不强。针对油藏存在的问题，采用油藏数值模拟方法，对油田开采历史进行了拟合，得出了剩余油分布状况，找出了剩余油的富集区域。同时还设计了4个开发方案，通过对比分析，推荐出最优开发方案。
