| 1 | 鄂尔多斯盆地南部地区上三叠统延长组6段地层水成因及其油气意义显示文摘鄂尔多斯盆地南部地区延长组6段(长6段)地层水化学分析结果表明,地层水总矿化度较高,离子以Cl-、(Na++K+)和Ca2+占绝对优势,水型主要为Ca Cl2型。总矿化度主要受Cl-和(Na++K+)控制,纵向上,其随深度的增加具有递增趋势,反映深部地层水逐渐浓缩,环境封闭性增强。平面上总矿化度与砂体厚度具有较好的一致性,沉积相控制了总矿化度的分布。南部地区长6段地层水具有较小的钠氯系数、镁钙系数、脱硫系数和阳离子交换系数,较大的变质系数,表明长6段地层水整体位于交替停滞带,为封闭缺氧的还原环境,有利于油气聚集和保存。分析表明,南部地区长6段地层水为与地表水隔绝的深层封闭水,总矿化度及Ca2+浓度均与孔隙度具有一定正相关关系,结合区域热演化史,综合表明长6段地层水成因与成岩作用和有机质的热演化等有密切联系,其是经过较强浓缩变质作用并受油气等有机流体影响的原始沉积成因水。综上所述,长6段油气伴生地层水反映的盆地南部油气藏处于稳定封闭的环境下,油气勘探前景良好。 | 刘福田 李荣西 左智峰 刘雪峰 赵帮胜 吴小力 李得路 | 2018 | 石油与天然气地质2018，39，6： | 10 |
| 2 | Distribution and Geochemical Characteristics of Fluids in Ordovician Marine Carbonate Reservoirs of the Tahe Oilfield显示文摘The Ordovician carbonate reservoirs in the Tahe Oilfield are highly heterogeneous, which have undergone multiple superimposed transformations by tectonic activities and karst processes, leading to an extremely complex fluid distribution. The geochemical characteristics of geofluids also display great disparities. Results show that the vertical distribution of oil and gas are continuous, however the oil-water interfaces in different blocks of the Tahe Ordovician Oilfield are numerous. Meteoric water infiltration is regarded as the main reason for the high oil-water interface and high water content to the north of Tahe Oilfield, especially in well blocks S78–S73. The isotopic values of deuterium-oxygen in the groundwater and carbon-oxygen from calcite veins confirm that formation water in Ordovician reservoirs of the Tahe Oilfield was a mix of meteoric water and connate water, and the proportion of meteoric water gradually increases from south to north, while connate water decreases. The Tahe Ordovician reservoirs are characterised by multiple hydrocarbon charges, and the general migrating direction is from southeast to northwest and from east to west. High production could be obtained in the northern area of the Tahe Oilfield since the oil layers are thick and oil is highly saturated. The residual water within the reservoirs is low, and heavy oil is dominant in this area. Only a small amount of pore water has been replaced by oil in the southern Tahe Oilfield, leading to low oil saturation and a high content of residual water. Crude oil is herein mainly of medium-light type. During the process of exploration in this region, acid fracturing reformation is usually required for wells to increase their output; however the yield is still low. | Mei Li Zhanghua Lou Rong Zhu Aimin Jin Ying Ye | 2014 | Journal of Earth Science2014，25，3： | 7 |
| 3 | 下扬子区上古生界构造作用与油气保存条件分析显示文摘基于中、新生代构造形变对下扬子地区海相地层及上覆盖层的影响,应用整体构造框架下的宏观保存体系评价思路,通过研究构造演化与隆升剥蚀、断裂构造作用、岩浆活动、水文地质条件、盖层的有效性等,对该区上古生界油气宏观保存条件进行了评价。(1)下扬子区上古生界油气保存条件地区差异性明显,具有'南北分带,东西分块'的特点;(2)下扬子区油气保存条件分为3类:句容—黄桥地区、海安凹陷中北部为Ⅰ类(有利)保存区;苏北盆地(东台—大丰地区、射阳地区、宝应—金湖南地区、姜堰—海安地区)、苏皖南地区(无为地区、望江—潜山地区、句容—常州地区)为Ⅱ类(较有利)保存区;下扬子其他地区为Ⅲ类(差)保存区。 | 彭金宁 张敏 刘光祥 吕俊祥 | 2015 | 石油实验地质2015，37，4： | 6 |
| 4 | 上扬子地块黔北坳陷及周缘水文地质-地球化学特征与油气保存显示文摘从地下水化学-动力学角度对上扬子地块黔北坳陷及周缘油气保存条件进行了研究。结果表明:黔北坳陷及周缘自震旦纪以来共经历了3次重要的水文地质旋回,即加里东期、海西期—印支期和燕山期—喜马拉雅期。黔北坳陷及周缘在加里东期和海西期—印支期是两次主要的油气成藏期,但加里东末期和燕山期—喜马拉雅期运动使得区内原已形成的油气藏几乎被破坏殆尽。多次构造运动和多期大气水下渗作用使得现今黔中隆起埋深小于2 500 m、黔北坳陷埋深小于3 000 m的地层水矿化度低,处于自由交替带且底界尚不清楚,油气保存条件较差;川南坳陷在埋深800 m的浅部地层已进入交替阻滞带,油气保存条件相对较好。 | 朱振宏 楼章华 金爱民 张润合 斯春松 姚根顺 | 2016 | 石油与天然气地质2016，37，6： | 6 |

| 6 | 渤海湾盆地东濮凹陷南部地区古水动力演化与油气运聚显示文摘油气的运移、聚集与地下水动力场密切相关。从古水动力场演化角度分析东濮凹陷南部油气运聚机理,流体流动与断裂开启性之间的匹配关系,并利用流体包裹体均一温度数据,结合研究区热演化史和生烃史特征分析了油气藏形成时间,恢复其油气充注过程。结果表明:研究区可划分为3个水动力单元:东、西次凹带发育泥岩压实水离心流;兰聊断裂带发育大气水下渗向心流;中央隆起带位于东西两侧离心流汇合越流泄水区,是油气聚集成藏的有利区域。东营组沉积期是石油最主要的运移、聚集期,该阶段油气主要聚集在中央隆起带断层下盘的底部;东营运动抬升剥蚀期是石油的主要调整运移期。早期形成的深层油气藏向构造高部位的顶部运移调整,重新聚集形成浅层次生油藏;馆陶组-明化镇组沉积期为天然气主成藏期,断层封闭性增强,天然气聚集在构造翼部的深部地层,形成'上油下气、顶油边气'的分布格局。 | 焦大庆 李梅 慕小水 徐田武 | 2014 | 石油与天然气地质2014，35，5： | 4 |

| 8 | Regional Geochemistry and Fluid Flow in the Palaeogene Aquifers of the Gaoyou Subbasin in the Southern Part of North Jiangsu Basin, China显示文摘Chemical analysis of groundwater in petroliferous basins can be an effective way to determine the regional hydrogeological regime and to evaluate the preservation conditions of hydrocarbons. This paper presents the hydrochemical distribution of both individual aquifers and different structural units within the Palaeogene strata of the Gaoyou subbasin in the North Jiangsu Basin, east China. The results show that the salinity of the Palaeogene aquifers in the Gaoyou subbasin displays a systematic increase from the central deep depression to the periphery areas, and shows a reverse trend as the burial depth increases. Salinity maps of individual aquifers suggest that formation water in the deep layers at the centre of the study area probably retains original features of fresh lake water. Geofluids near the central deep depression of the Gaoyou subbasin migrate vertically through the Zhenwu and Hanliu faults, while those of the northern slope belt mainly flow laterally through aquifers. Both low and high salinity formation water can be found in the hydrocarbon producing areas. The low salinity zones commonly affected by infiltrated meteoric water are unfavourable conditions for the preservation of trapped hydrocarbons. | LI Mei | 2016 | Acta Geologica Sinica(English Edition)2016，90，3： | 0 |
