西非北加蓬次盆G区块UPC段油气成藏模式及主控因素

 加蓬盆地作为西非被动大陆边缘重要的含油气沉积盆地,是目前油气勘探的热点地区,而G区块是中国在北加蓬次盆地的重要投资勘探开发区块。对该区块地层和沉积特征,以及烃源岩、储层、盖层、输导体系等油气成藏条件的分析表明,Ｇ区块石油地质条件优越,发育有优质烃源岩,而U.P.C.段作为G区块的主力产油层,储层物性很好,且该区块储盖组合配置关系良好。G区块油藏多为受构造控制的断背斜、断块油藏,油气主要富集在构造高点。研究表明,Ｇ区块油气成藏模式为“深源充注,断层盐边砂体输导,构造成藏”,油气成藏的主控因素为与盐运动相关的构造圈闭。

双阳盆地构造单元划分及构造演化史

根据吉林中部双阳盆地二维地震剖面解释和盆地地层分布特征,对盆地内断裂和褶皱构造的发育特征进行了研究,认为双阳盆地为一不对称的复向斜断陷型改造盆地,盆地长轴方向NW-SE,近圆形,由央凹陷区,东北部隆起区,南部隆起区,西部斜坡区四个构造单元组成;盆地形成于晚侏罗-早白垩世早期,石炭、二叠系变质岩和海西期花岗岩构成盆地的沉积基底,其构造演化经历了石炭-三叠纪稳定沉降及火山喷发阶段、侏罗纪断陷初始阶段、白垩纪断陷发展阶段、古近纪-新近纪广泛抬升阶段4个演化阶段。本文的研究,不仅划分了盆地的构造单元,也建立了盆地构造演化模式,为该盆地的油气资源勘探提供了一定的科学依据。     

沁水盆地东部构造演化特征及构造物理模拟

沁水盆地东部煤层气勘探潜力巨大,构造演化特征相对独特。依据野外地质踏勘资料,对沁水盆地东部的构造特征进行系统研究。利用平衡剖面回剥方法,定量分析典型剖面的运动学参数。在研究区构造几何学、运动学特征分析基础上,基于构造物理模拟实验,再现了沁水盆地东部的构造演化过程,从而对研究区构造演化取得了新的认识。研究表明,沁水盆地东部依次经历了弱挤压-强挤压-弱伸展-强伸展的演化过程,可将其构造演化划分为板块拼合盖层沉积(J_1前)、陆内强烈挤压变形(J_2～J_3)、微弱伸展活化(K-E)和陆内伸展裂谷(N-Q)4个阶段。此构造演化对沁水盆地东部煤层气的聚集与勘探开发具有重要影响,其动力来源主要受控于区域构造应力场的重大转变。早侏罗世以前,板块碰撞拼合及印支运动的辐射将沁水盆地东部置于NNW-SSE向挤压应力场;中-晚侏罗世,研究区开始出现重要构造分异与转折,整体转向NW-SE向强挤压应力场,逆冲断裂雏形在此阶段形成;白垩纪-古近纪,区域应力场由NW-SE向挤压应力场转变为NW-SE向伸展应力场,研究区构造体制发生重大转折;21世纪以来,研究区进入陆内伸展改造,构造格局至此基本定型。     

北非NK地区上白垩统灰岩裂缝油藏成藏因素

北非Pelagian盆地是一个重要的含油气盆地,在North Kairouan地区已经取得了一些积极的勘探成果,但仍存在油藏成藏条件复杂,主控因素不清、勘探难度大、勘探成效低等问题。以地震、钻井及分析化验资料为基础,对研究区上白垩统灰岩裂缝储层成藏条件进行了综合分析,认为该区油气成藏主要受裂缝的走向及发育程度、有效输导层以及盖层的分布共同控制,北西向断层及裂缝发育、具备复式输导层和厚层盖层的构造发育区为有利油气聚集区,指出NK地区中部复杂背斜带和东部鼻状隆起带为两个有利油气勘探带,对该区碳酸盐岩油藏勘探具有指导意义。     

季曼-伯朝拉盆地油气地质特征及勘探潜力分析

季曼-伯朝拉盆地是俄罗斯重要的含油气盆地之一,经历了前裂谷、裂谷、被动陆缘和前陆4期演化阶段,形成现今古被动边缘-前陆叠合的构造格局。盆地不同期次的构造演化及叠合效应控制着盆地的烃源岩、储层发育和分布,进而控制了油气分布规律。盆地的主要烃源岩和储盖组合多发育于中晚古生界,上泥盆统多马尼克组烃源岩是盆地的主力烃源岩;主力储层为中上泥盆统、石炭系-下二叠统的碳酸盐岩和碎屑岩,储层物性整体较好;圈闭类型多为岩性-构造型圈闭;盆地油气主要沿着早期裂谷的反转隆起分布。盆地勘探程度分布不均,其中东部前渊区以及海域勘探程度较低,油气地质综合分析表明,前渊地区是最有潜力的含气区,海域仍具有良好的勘探前景,是未来勘探的两个有利区带。

Since 1972, he has engaged in the research work in oil & gas reservoir engineering in RIPED, holding the posts of the director of Oil & Gas Field Development Department, vice president and chief engineer of RIPED.For more than 50 years, academician Han Dakuang has been engaged in the scientific research and teaching work of oil and gas field development engineering. On the one hand, he went deep into the oilfield production realities, carried on the comprehensive study of Reservoir Engineering and gave the strategic countermeasures; on the other hand, he actively carried out the research and application of seepage mechanics and interface physical chemistry, and became one of the pioneers of reservoir numerical simulation and enhanced oil recovery technology. His contributions and achievements in oil and gas field development engineering include:Reservoir Engineering Study area: In the early 1950s, academician Han Dakuang took part in China's first oil field waterflooding program — the design of Yumen Laojunmiao Oil field waterflooding program, who was responsible for the seepage calculation. Since then, he was repeatedly responsible for or participated in the compiling work of the oil and gas field development plans, annual plans and the discipline development plans, which made contributions to the strategic arrangements and the scientific and technological progress of China's oil field development over the years. Aiming at the development problem of China's old oilfields at high water-cut late stage, he systematically studied the new pattern of residual oil distribution and the new changes of the oil field development situation, and proposed strategies, concepts and new technology development direction, which is of important guiding significance for the elderly Oilfield enhanced oil recovery and to increase recoverable reserves.
