红柳构造坡折带层序地层学模式与油气分布

在对地震、测井和钻井等资料详细分析的基础上，将济阳坳陷红柳地区下第三系划分出了7个三级层序、19个体系域．在层序地层单元划分和对比的基础上，结合断层上下盘地层厚度的差异变化所反映的古地形，认为济阳坳陷红柳地区在下第三系沉积时期，发育两种不同类型的构造坡折带，并建立了该区的构造坡折带层序地层学模式，研究了构造坡折带层序地层学模式与油气的关系，认为第Ⅰ，Ⅱ层序间的界面附近可形成有利的地层不整合覆盖圈闭与构造-岩性圈闭；第Ⅳ层序低位域可作为油气的运载层，在合适构造的匹配下，可形成有利的构造圈闭或构造-岩性圈闭，并对有利区带做出了预测．     

Pool-formation and secondary change of biodegraded viscous oils: Case study of reservoir section in the Zhengjia-Wangzhuang Oilfield, Jiyang Depression

It is demonstrated by various geochemical indexes that the Zhengjia-Wangzhuang Oilfield with viscous crude oil in the Jiyang Depression has been sourced from the contribution of matured source rocks in the upper Es4. The principal cause leading to the densification of crude oils would be biodegradation, with the degradation level of crude oils being ranked as 2-8; vertically, the biodegradation level increases from the top to bottom of the oil column, with a distinctive biodegradation gradient occurring. Calculated parameters of sterane, terpane and methyl-phenanthrene have indicated that the source-rock's maturity of crude oils and asphaltic sands ranges from 0.7 to 0.9, and based on the calculation of Easy Ro model, the temperature of hydrocarbon generation in the source rock would be within 120-140℃, which coincides with the measurements of reservoir inclusions. The measured homogenization temperature would represent the generation temperature of the source rock, and be fairly different from that of reservoir while being charged with hydrocarbons, which reflects the hydrocarbon-charging to be a fast process, and the period of pool-formation to be consistent with that of peaked generation. According to the evaluation of generation history, the pool-formation could have been occurring in 7-15 Ma. And the biodegradation of crude oils in the study area would be considered to take place in 4-15 Ma based on the examination of biodegradation order and dynamic calculations.     

The generation and accumulation of natural gas from Yinan 2 gas pool in Kuqa Depression

By using the methods of hydrocarbon generation kinetics and carbon isotope kinetics, combined with geological background of natural gas pool formation, the generation and accumulation of natural gas from Yinan 2 gas pool was studied in Kuqa Depression of the Tarim Basin. Natural gas of Yinan 2 gas pool is mainly derived from Middle and Lower Jurassic coal-bearing source rocks, and generally belongs to long time-accumulated gas. It is suggested that Yinan 2 gas is chiefly accumulated in the last 5 Ma, its Ro ranges from 1.25% to 1.95%, and the loss rate of natural gas is about 25%-30%. This work not only complements and reduces the deficiency of formation model of natural gas pools which traditionally depends on the matching relationships between source rock, reservoir, cap rock, and trap, but also is a useful reference in the study of other gas pools.     

取精估计法在八面河探区资源潜量评价中的应用

针对油气勘探过程中的取精现象 ,即随着勘探程度的提高油藏规模逐渐减小这一规律 ,通过已发现油藏规模的对数值和发现序数呈一负斜率的直线关系 ,可以外推未来待发现油藏的规模分布。对前人提出的油藏大小对数值符合变方差正态分布的观点提出了改进方案 ,并将其应用于渤海湾盆地济阳坳陷南斜坡八面河探区油气潜力和勘探效益的预测。预测结果表明 ,从模拟的勘探效益变化趋势可知 ,未来 1口探井的勘探量平均将低于 30×10 4 t,且处于一种低效且稳定下降的阶段。预计再钻探井 16 0口 ,将发现 48个油藏 ,资源潜量均值为 2 7× 10 6t。这种预测方法最适宜应用在勘探程度较高、产量比较稳定的探区。     

未成熟油藏的储层成岩作用

金湖凹陷西园－崔庄地区阜二段储层（不论是生物粒屑灰岩还是砂岩）的成岩作用及其孔隙结构都与其含油性关系密切。含油的储层成岩作用浅、物性好、孔喉大、孔隙连通性好；不含油的砂岩和灰岩碳酸盐胶结和颗粒次生加大作用明显加强，物性和孔隙结构差，基本上失去了储集性。由该区的油气成因模式发现，未熟油的生成和聚集时间早（相当于早成岩Ａ亚期与Ｂ亚期的过渡期），较早进入储层的油气抑制了进一步的胶结、颗粒加大等作用，使其仍保持着早成岩Ｂ亚期初期的物性和孔隙结构。储层性质受控于成岩演化，又受控于油气聚集和断块差异活动。     

艾司西酞普兰与帕罗西汀治疗抑郁症的临床对照研究

目的比较艾司西酞普兰与帕罗西汀治疗抑郁症的有效性和安全性。方法将在精神科治疗病例随机分为艾司西酞普兰组和帕罗西汀组,应用汗密顿抑郁量表（}IAMD）（17项）评定治疗效果,应用副反应量表（TESS）评定不良反应,在入院时、1、2、4周分别进行对照,分别完成43、44例。结果研究终点两组疗效显示：艾司西酞普兰组有效率为83．7％,帕罗西汀组有效率为86．4％,两组有效率无统计学差异（P〉0．05）,但艾司西酞普兰起效要快,2周时艾司西酞普兰组的HAMD减分率较帕罗西汀组明显（P〈0．05）;艾司西酞普兰副作用要少,但共有副作用两者发生率无显著性差异（P〉0．05）。结论艾司西酞普兰治疗抑郁症疗效与帕罗西汀相当,但起效要快、不良反应要少,是治疗抑郁症的较好选择。     

库车坳陷东部下—中侏罗统砂岩流体包裹体特征与油气成藏期次研究

库车坳陷东部下—中侏罗统砂岩储层中发育丰富的液烃包裹体.对与液烃包裹体共生的含烃盐水包裹体特征和显微测温数据的系统分析表明,该地区自中新世中—晚期以来油气持续充注,并存在2期主要的充注过程.第一期发生在早成岩阶段晚期,主要为低成熟油气充注,充注时间为12～10 Ma(大致相当于中新世吉迪克期);第二期发生在中成岩阶段早期,充注时间为9～7 Ma(大致相当于中新世康村期),主要为低成熟油气充注,并伴有少量的发浅黄色荧光的成熟油气充注.不同层位包裹体的丰度有明显差别,下侏罗统阿合组(J1a)和阳霞组(J1y)包裹体丰度(GOI)明显比中侏罗统克孜勒努尔组(J2k)和恰克马克组(J2q)高,这可能与砂岩的粒度有关.下侏罗统砂岩粒度较大,发育比较优质的储层,有利于包裹体发育;中侏罗统砂岩粒度较细,储层物性较差,不利于包裹体发育.

川西拗陷中侏罗统沙溪庙组储层特征及综合评价

川西拗陷中段中侏罗统沙溪庙组为多物源背景下发育的三角洲—滨浅湖沉积体系，不同物源背景对储层影响较大且勘探效果差异明显。以岩屑、岩芯等实物资料为基础，结合薄片观察及储层测试分析资料，对研究区沙溪庙组龙门山中段（近物源）及龙门山北段和米仓山（远物源）两大物源沉积体系的储层特征进行了对比性研究。结果表明，近源体系储层砂岩整体成分成熟度低、粒度较粗，有利储层为成分成熟度高、碳酸盐胶结物含量低、裂缝发育的细粒砂岩，保孔效应的强弱决定了优质储层的发育；远源体系优质储层的特征主要为成分成熟度相对较低、碳酸盐胶结物含量低、长石富集的中粒砂岩，溶蚀作用的增孔效应强度决定了优质储层的发育。以此为基础，分别建立了两大物源体系的储层综合分类评价标准，评价结果显示，远源体系的储层发育更优，其有利储层分布面积远大于近源体系。
