莺歌海盆地乐东斜坡区LD-A气田的发现进一步证实了高温高压岩性圈闭领域的巨大资源潜力。该气田储层压力系数最高可达2.3,流体超压诱发的水力破裂对天然气的运聚起到重要的控制作用,明确超压条件下地层是否发生水力破裂及其演化过程是深入研究莺歌海盆地天然气成藏的关键。为此,在明确天然气垂向输导体系的基础上,以岩石破裂准则为理论依据,利用地应力及岩石抗张强度确定水力破裂模式,厘定了地层水力破裂条件;最终结合超压演化,分析了水力破裂动态演化过程对天然气成藏过程的控制作用。研究结果表明:(1)断裂、亚地震断裂和裂缝共同构成了LD-A气田天然气垂向输导体系,超压诱发的水力破裂控制了输导体系的启闭性和有效性,决定了天然气能否规模富集。(2)LD-A气田的中深层发育张性水力破裂,其中LD-A1气区现今黄流组顶部处于水力封闭状态,梅山组顶部处于水力渗漏状态;LD-A2气区和LD-A3气区上中新统黄流组顶部和中中新统梅山组顶部现今均处于水力封闭状态。(3)LD-A气田的水力破裂演化存在封闭—破裂—封闭型(LD-A1气区与LD-A2气区)和持续封闭型(LD-A3气区)2种类型,不同的水力破裂演化过程导致了天然气在不同层位砂体差异性充注和富集。结论认为,LD-A1气区与LD-A2气区浅层上新统莺歌海组二段和上中新统黄流组优质砂体是天然气有利富集对象,LD-A3气区应在埋藏更深的梅山组砂岩中寻找突破。

对质子交换膜燃料电池催化剂浆料制备工艺中浆料的混合过程进行了深入研究。通过实验测量获得了浆料流变特性、密度与铂-碳颗粒体积分数之间的关联关系,并建立了浆料混合过程的“液-固-气”三相流动模型。在此基础上,结合桨叶搅拌和高速剪切分散作用,对浆料混合过程中混浆装置内部的流场结构和铂-碳颗粒分散特性进行了数值模拟。结果表明,在搅拌桨叶作用下,混浆装置内形成的大尺度流动结构未能有效抑制铂-碳颗粒的沉降现象。然而,引入高速剪切分散装置后,不仅能够通过抽吸作用缓解铂-碳颗粒的沉降,还能通过狭缝喷射流动增强混合效果,从而显著改善铂-碳颗粒在流场中的分散特性。上述结果为混浆装置结构设计与改进提供了重要的指导,为质子交换膜燃料电池催化剂浆料的高效制备提供有力的理论支撑。

Various deep-water deposits developed in the Yinggehai Basin and Qiongdongnan Basin(Ying-Qiong Basin)in the northern South China Sea,making the two basins significantly hydrocarbon-producing areas and ideal for studying the genetic mechanism and sedimentary characteristics of deep-water clastic *** cores,image well logging,heavy mineral assemblages,and seismic data,we thoroughly studied the geometry,tectonic background,driving mechanism and source-to-sink process of deep-water deposits in the study *** results showed that:(1)there were five genetic mechanisms of deep-water clastic rock,i.e.,slides,slumps,debris flows,turbidity currents,and bottom currents.(2)The sliding deposits were distributed from the delta front to the continental slope *** slumping deposits were mainly distributed at the continental slope toe or the basin’s central area,far from the delta front The turbidity deposits were widely developed in the deep-water area,but with huge differences in *** bottom currents mainly reworked previous deposits far from the slope.(3)Slip and extension along the preexisting fault zone were the main structural factors that drive the axial channel formation at the slope foot.(4)The sand-rich gravity sediment flows in the Ying-Qiong basin were primarily caused by the direct supply of terrigenous debris into the marine environment over the slope break.

断裂体系发育是珠江口盆地文昌A凹陷西部地区新生代构造演化的重要表现形式。利用最新的三维地震资料,在精细刻画断裂体系静态特征的基础上,结合断层活动速率计算恢复断裂体系的动态演化过程,明确了文昌A凹陷西部地区新生代断裂体系发育的时空差异;并结合区域应力背景分析,探讨了断裂体系演化的成因机制,认为新生代以来三大板块间俯冲、碰撞及古南海俯冲消亡、新南海扩张共同造成的南海北缘区域伸展应力场顺时针旋转控制了断裂体系演化的时空差异。研究表明,文昌A凹陷西部地区断裂体系的发育演化经历了裂陷、拗陷与构造活化三个阶段,分别发育了NE(NEE)向、近EW向以及NW(NWW)向三组优势方向断裂,揭示了区域应力场伸展方向由NW—SE向到近SN向再到NNE—SSW向顺时针转变的过程;依据断裂的组合及沿承关系可将其划分为早期发育的NE向与后期发育的NW向两组交叠断裂带,NE向断裂带活动强度大、具有强烈伸展性质,NW向断裂带与基底先存断裂密切相关,活动强度弱、叠加一定走滑性质。文昌A凹陷西部新生代断裂体系演化的时空差异是对南海北缘区域应力场顺时针旋转的响应。

There are rich natural gas resources in the northwestern South China Sea deepwater areas, with poor degree of exploration. Because of the unique tectonic, sedimentary background of the region, velocity model building and time-depth conversion have been an important and difficult problem for a long time. Recent researches in this direction have revealed three major problems for deepwater areas, i.e., the way to determine error correction for drilling velocity, the optimization of velocity modeling, and the understanding and analysis of velocity variations in the slope areas. The present contribution proposes technical solutions to the problems：（1） velocity correction version can be established by analyzing the geology, reservoir, water depths and velocity spectrum characteristics;（2） a unified method can be adopted to analyze the velocity variation patterns in drilled pale structural positions;and （3） across-layer velocity is analyzed to establish the velocity model individually for each of the layers. Such a solution is applicable, as shown in an example from the northwestern South China Sea deepwater areas, in which an improved prediction precision is obtained.

在系统整理大地构造资料的基础上,研究莺歌海盆地隐蔽式走滑构造变形及其与沉积、超压、油气运移之间的关系。研究发现:(1)左行走滑伸展派生的局部张性破裂主要发育在距今10.5 Ma之前,这些破裂在东斜坡大型鼻状凸起大量分布,并在晚期流体超压作用下幕式活化,成为盆地斜坡地区油气垂向运移的主导通道;(2)右行走滑伸展有利于沉积速率增大和区域欠压实盖层形成,其派生局部张性破裂作用是底辟发育的诱发动力,而底辟发育又进一步放大局部张性破裂发育规模;(3)左行走滑作用在距今10.5 Ma开始减弱,产生北部挤压、南部旋转伸展(北挤南伸)的构造运动,造成盆地北部河内凹陷地层抬升剥蚀、南部莺歌海凹陷碎屑岩供应量激增,最终导致莺歌海凹陷在东、西非对称斜坡地貌上分别形成迁移式斜坡水道化海底扇和叠置式海底扇。

近年来,随着勘探程度提高,南海西部近海盆地勘探难度增大,大中型油气田勘探未获大的突破。2020年,通过解放思想、转变思路、创新认识,转向领域勘探,在珠江口盆地西部增压型断裂转换带、涠西南凹陷流一段湖底扇、琼东南深水梅山组海底扇等多个领域获得勘探突破。通过对南海西部近海盆地主要凹陷油气资源潜力和勘探阶段及其分布不均衡性的分析,以及对已发现大中型油气田分布与生烃强度、构造背景、裂隙(断裂)之间关系的研究,认为南海西部近海仍然具备寻找大中型油气田的广阔前景,提出了必须走领域突破之路,明确了大中型油气田勘探必须围绕六大富烃凹陷展开,天然气勘探要优先突破莺-琼盆地的高强度生气中心-优势汇聚背景-垂向裂隙带三元耦合区,原油勘探必须紧抓珠江口西部和北部湾断陷盆地的大型增压型断裂转换带和具有隆起背景的近源构造-岩性复合圈闭群。
