为此，以渤海J Z S潜山油藏为例，利用其丰富的动态资料，分析了不同油井的见水特征，总结得出了该潜山裂缝性油藏“台阶形”见水特征及由局部裂缝见水逐渐发展为整体见水的含水率上升规律；基于该潜山裂缝性油藏的见水规律，选取剖面压力均等模型作为裂缝性油藏见水预测模型，通过拟合实际油井的见水特征反算了地下裂缝的分布情况，分析得出潜山裂缝性油藏具有较强的非均质性以及其裂缝具有对数正态分布的特征。

研究认为，将裂缝对数正态分布这一特征作为约束条件应用到潜山裂缝性油藏的地质建模中，可在很大程度上提高该类油藏含水率拟合结果的准确性，这对类似裂缝性油藏的数值模拟和有效开发具有借鉴意义。

After that,the investigations arrived at a conclusion,considering the buried-hill reservoi strong anisotropy,with the characteristics of log-normal distribution of fractures.Researc that the log-normal distribution of fractures could be taken as a constraint in the geologic m odelingied-hill fracture reservoirs and could be used to improve the accuracy of history matching the water cut inthese reservoirs,providing valuable references for numerical simulation and high-efficiency development ofsimilar fracture reservoirs.Key words： fracture reservoir；buried-h i l l reservoir；water breakthrough rule；fracture distribution；log-normally distribution；numerical simulation.随着成像测井技术的日趋成熟，对潜山裂缝性油藏井眼 裂缝的识别越来越准确，而对井间裂缝分布的识别，虽然相关理论研究比较多，但截至目 尚未 ，更没有成熟的技术[19]。

潜山裂缝油藏开发特征及挖潜方向房娜;姜光宏;李云鹏;程奇;郑浩【摘要】潜山裂缝油藏储集空间与渗流规律复杂,开发难度大,不同开发阶段制订合理的挖潜策略是决定该类油藏高效开发的关键.以渤海锦州A油田潜山裂缝油藏为例,在总结裂缝油藏产量递减快、含水上升快以及基质系统原油挖潜难度大等开发难点的基础上,采用数值模拟技术,研究基质系统和裂缝系统在不同开发阶段的供油特征,划分潜山三大开发阶段,针对不同开发阶段提出相应的挖潜方向.结果表明,开发早、中、晚期分别采用液流转向技术、周期注水技术及降压开采技术可充分控制含水上升速度,提高裂缝油藏的最终采收率.该项配套技术对于改善裂缝油藏开发效果具有广泛的实际意义,为同类油藏的开发提供借鉴.%Buried-hill fractured oil reservoirs are characterized by complex reservoir space and flow laws and their development is of high difficulty.The key to the efficiency development of this type of oil reservoirs is to formulate rational potential tapping strategies for different development stages.In this paper, the buried-hill fractured oil reservoir in Jinzhou A Oilfield, Bohai Bay was taken as the example.First, the development difficulties of fractured oil reservoirs were summarized, including fast declines of oil production, fast increasing of water cut and high-difficulty potential tapping of crude oil in matrix systems.Second, the oil supply characteristics of matrix systems and fractures systems in different development stages were investigated by using the numerical simulation technology, and three development stages of buried-hill oil reservoirs were classified.And third, the potential tapping directions corresponding to different development stages were defined.Itis indicated that the rising velocity of water cut can be controlled effectively and the ultimate recovery factor of fractured oil reservoirs canbe improved if fluid diversion technology, cyclic water flooding technology and blowdown technology are used in early, middle and late development stage, respectively.This set of technology is widely of practical significance to the improvement of fractured oil reservoir development effects, and it can be used as the reference for the development of similar oil reservoirs.【期刊名称】《特种油气藏》【年(卷),期】2017(024)003【总页数】5页(P90-94)【关键词】潜山裂缝油藏;数值模拟;挖潜方向;液流转向;周期注水;锦州A油田【作者】房娜;姜光宏;李云鹏;程奇;郑浩【作者单位】中海石油(中国)有限公司天津分公司,天津 300452;中海油能源发展股份有限公司工程技术分公司,天津 300452;中海石油(中国)有限公司天津分公司,天津 300452;中海石油(中国)有限公司天津分公司,天津 300452;中海石油(中国)有限公司天津分公司,天津 300452【正文语种】中文【中图分类】TE349潜山裂缝油藏具有裂缝发育、非均质性强、储集空间与渗流规律复杂等特征，因此，裂缝油藏的开发与常规砂岩存在较大差异[1-6]。

渤海湾盆地潜山油气富集规律与勘探
渤海湾盆地中、古生界或前古生界潜山油气藏非常发育,到目前为止共探明67个油气田(藏).其油气富集规律①是冀中坳陷富集程度最高,济阳坳陷、辽河坳陷次之,黄骅坳陷、渤中坳陷最低;②是中位序潜山油气田(藏)富集程度最高,低位序次之,高位序、顶位序最低;③是潜山油气田(藏)以断块山圈闭为主,以褶皱山圈闭为辅;最后是潜山油气田(藏)以大、中型为主,以小型为辅.盆地内潜山油气富集原因是"新生古储"的结果,即是古近系多套烃源岩覆盖多位序潜山地层,并经断层、地层不整合通道将极为丰富的烃类运移至不同位序潜山圈闭成藏.指出了多个有利勘探目标,为下一步的潜山油气勘探提供了建议.

JZS油田潜山裂缝储层形成机制及分布预测黄保纲;汪利兵;赵春明;杨庆红;曹树春;童凯军;宋洪亮【摘要】According to litho-chemical index and microscopic features,the buried hill in JZS oilfield can be divided vertically from top to bottom into three zones with different levels of chemical weathering: weathered, semi -weathered and un-weathered zones. Similarly, based on core observation, thin section analysis and image logging and in combination with production logging data, it also can be divided into three zones from surface to core: weathered crust, semi-weathered crust and basement, corresponding to the three chemical weathering levels respectively. The reservoir space of buried hill is dominated by structural fractures in semi-weathered crust and the solution fractures in weathered crust. The development of fracture reservoir is controlled by multiple factors such as lithology, tectonic movement, weathering and dissolution, of which tectonic movement is the main controlling factor. According to the timing of faults and their dip angle, the structural fractures of buried hill in JZS can be grouped into four types: early semi-filled/filled horizontal fracture, early semi-filled/filled vertical fracture, late semi-filled cataclastic fracture and late open slant fracture. By using crude oil inclusion detection technique,we recognized that the main effective fracture types of the buried hill in JZS are late semi-filled cataclastic fracture and late open slant fracture. We also established criteria for identifying effective fractures with conventional logging data calibrated by core and image logging data andrestructured a new effective structure identification curve for fractured reservoir inversion and distribution prediction. Application shows that the prediction results of this method correlate well with that of other geophysical methods. This method provides the neccesary geological basis for development well emplacement.%依据岩石化学指标和微观特征,JZS潜山纵向上自上而下化学风化程度相应地可划分为风化、半风化和未风化3个级别.以岩心观察、岩石薄片鉴定和成像测井等资料为基础,结合生产测井资料,认为JZS潜山由表及里也可分为风化壳、半风化壳和基岩3个带,与化学风化级别相对应；潜山储层储集空间主要为半风化壳的构造缝及风化壳的溶蚀缝；裂缝储层发育受岩性、构造运动及风化溶蚀作用等因素综合控制,主控因素是构造运动.按断裂期次及倾角大小,JZS潜山构造缝可划分为4类,即早期半充填—充填水平缝、早期半充填—充填垂直缝、晚期半充填碎裂缝和晚期开启倾斜缝.应用原油包裹体检测技术确定JZS潜山主要有效裂缝为晚期开启倾斜缝和半充填碎裂缝.通过岩心和成像测井资料标定,建立了JZS潜山常规测井资料识别有效裂缝的标准并重构有效裂缝识别曲线.利用重构曲线,进行裂缝储层反演及分布预测.该方法预测结果与其他地球物理方法预测结果吻合较好,为开发井部署提供了地质依据.【期刊名称】《石油与天然气地质》【年(卷),期】2011(032)005【总页数】8页(P710-717)【关键词】裂缝储层;形成机制;储层预测;变质岩潜山;太古宇;辽西低凸起;渤海海域【作者】黄保纲;汪利兵;赵春明;杨庆红;曹树春;童凯军;宋洪亮【作者单位】中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452;中国海洋石油(中国)有限公司天津分公司,天津300452【正文语种】中文【中图分类】TE122.2Key words：fractured reservoir，formation mechanism，reservoir prediction，metamorphic rock buried hill，Archaean，Liaoxi low uplift，Bohai SeaJZS油田位于渤海辽东湾海域辽西低凸起中段，与辽西凹陷和辽中凹陷毗邻。

生物标志物参数表明沙西北地区已发现的原油位于沙河街组。

曹妃甸2-1油田的潜山储层岩性为碳酸盐岩，潜山的原油具有高的伽马蜡烷指数（G/H)以及相对低4-甲基甾烷参数（4M S I)，具有相对轻的正构烷烃碳同位素值（整体轻于-29%。

），主要为沙河街组一段（沙一段）的油源。

曹妃甸1-6油田为花岗岩潜山储层，潜山的原油具有相对高的4M+I( >0.4)，正构烷烃的碳同位素值偏重（重于-29%)，可能指示着以沙三为主的油源。

曹妃甸2-1潜山直接披覆沙一段，沙一段源岩生成的原油可近距离充注至潜山储层中，为披覆式的源储对接成藏模式。

曹妃甸1-6油田上覆为东营组，其丰度与热演化程度低，主要作盖层。

歧口凹陷的原油侧向通过砂体运移侧向充注至曹妃甸1-6潜山圈闭中，表现为侧向砂体输导油气成藏特征。

通过岩心观察和铸体薄片实验分析了C F D2-1-2井潜山风化壳结构特征，揭示了沙西北地区潜山风化壳结构可能不具备侧向长距离输导油气的能力，与潜山直接披覆接触的有效烃源岩或者发育沟通源储的砂体是潜山油气成藏的基础。

【摘要】针对X油田纵向及平面水淹不均、剩余油分布规律复杂等问题,从层内、层间及平面等角度进行研究.研究认为,层内水淹受韵律性及重力共同作用,层间水淹受层间夹层影响,平面水淹规律受沉积相带控制.纵向上剩余油分布于各小层顶部,平面上主河道侧向、断层附近、潜山井区等剩余油富集.采取油井转注实现井网重塑、增加新井完善注采井网等针对性挖潜策略,在实践中取得了显著效果.
