    • 摘要: 为进一步提高特低渗透油藏水驱开发后的采收率,将界面活性较强的新型两性离子双子表面活性剂MGS-3和乳化能力较强的阴离子型表面活性剂AES相结合,研制了一种适合特低渗透油藏的复合表面活性剂驱油体系,具体配方为0.2%MGS-3+0.1%AES,并评价了其界面活性、乳化性能、吸附性能、润湿性能和驱油效果。结果表明:该复合表面活性剂驱油体系具有良好的界面活性,能使油水界面张力达到10^(-3)mN/m数量级;体系具有较强的乳化能力,乳状液静置120 min后的析水率约为50%;此外,该复合表面活性剂驱油体系还具有良好的抗吸附性能和润湿改变能力;特低渗岩心水驱后注入复合表面活性剂驱油体系能使采收率继续提高20%以上,驱油效果明显优于单一表面活性剂。现场应用结果表明,S区块实施复合表面活性剂驱油措施后生产井的日产油量显著提升,含水率有所下降,取得了明显施工效果,具有较好的推广应用前景。

    • 摘要: 传统数值模拟方法未能精细刻画特低渗透油藏非达西渗流规律,导致预测开发指标比实际生产数据偏高.针对上述问题,首次建立五参数法对油藏非均质性进行定量计算,根据不同的储层非均质性和开发程度,提出三种特低渗透油藏数值模拟方法来精细刻画流体渗流规律.并通过特低渗透油藏渗流阻力等效表征及流动单元间双向渗流阻力赋值方法,精准求得了单井及各层的产量.将上述方法应用到渤海X特低渗透油藏产量预测中,方法预测的产量与实际产量相对误差小于0.4%,较传统数模方法预测精度可提高20个百分点以上.该模型不仅为特低渗透油藏产量预测奠定了坚实基础,且可应用于致密油气藏、稠油油藏等数值模拟模型中,具有较强的推广价值.

    • 摘要: 安塞特低渗透油田进入中高含水期后,主力油层普遍遭到水洗,多井低产,剩余油挖潜方向不明.以王窑区为例,基于现代沉积学、高分辨率层序地层学、测井及开发地质学理论基础,结合野外露头、检查井取心及开发测试资料,揭示了单油砂体尺度储层非均质特征、注采连通状况及剩余油分布规律.研究表明,单砂体非均质性对低渗透油藏水驱过程具有重要影响,对开发层系划分组合、井网形式及井排距选择、注水开发调整具有重要启示.通过开展缩小井排距加密调整、单砂体注采对应关系完善、精准压裂、调驱调剖等综合调整,预测采收率提高4%~6%,对同类油田中后期稳产意义重大.%After the low permeability oil field of Ansai enters the medium and high water-cut stage,the main oil reservoir is washed,the production of many wells is low,and the direction of remaining oil digging is unknown.Taking Chang 6 oil layers of Yanchang formation in Wangyao area as the object,on the basis of modern sedimentology,high-resolution sequence stratigraphy,basic logging theory and development geology,combining the rock outcrop,sealing core drilling in-spection well and test data,the characteristics of single oil sands scale reservoir heterogeneity,injection and mining connectivity and distribution of residual oil are revealed.The results show that the heterogeneity of single sand bodies has an important influence on the water flooding process of low permeability reservoir,and it also has important inspiration for the division and combination of the development oil layer,the form of well network and the adjustment of water injection.The recovery rate is increased by 4 % ~ 6 % through comprehensive adjustment as pattern infilling,adjustment of injection-production relation of the single sand body,the precise fracturing and profile control.

    • 摘要: 开展注入水中微生物对特低渗透储层伤害规律及推荐指标研究,对特低渗透油田精细注水、效益注水有着重要的指导作用.在注入水中微生物特征分析和特低渗透储层孔喉特征分析的基础上,针对3种级别的特低渗透储层,分别开展了3种微生物硫酸盐还原菌(SRB)、铁细菌(IB)和腐生菌(TGB)的低、中、高3种浓度的27组岩心流动实验.结果表明:微生物的注入浓度、注入量及匹配度(自身形态与储层喉道的匹配程度值)是影响特低渗透储层渗透率损失值的3种主导因素;随着微生物注入浓度、注入量及匹配度的增大,最终渗透率损失值将增大;在3种微生物中,对储层伤害程度呈现硫酸盐还原菌(SRB)>腐生菌(TGB)>铁细菌(IB)的规律,应以SRB作为微生物指标中重点控制指标.针对特低渗透油藏储层,提出了注入水中微生物控制指标.%Researches on the damage laws and recommended indicators to the ultra-low permeability reservoir caused by the microbiles in the injected water have important guiding roles for the fine and effective water injection development of this kind of the oilfield.Based on the analyses of the microbial properties in the injected water and the pore throat characteristics of the ultra-low permeability reservoir,three kinds of the microbile (Sulfate reducing bacteria-SRB,iron bacteria-IB and total growth bacteria-TGB) were considered with three different microbial concentrations for twenty-seven core flow experiments with three levels of the ultra-low permeability.The results show that the injection concentration,injection rate and compatibility (The matched degree between the self-configuration and reservoir pore throat) of the microbile are three leading factors that influence the permeability loss value of the ultra-low permeability reservoir;with the rise of the injection concentration,injection rate and compatibility of the microbile,the ultimate permeability loss value will be increased;for the three microbiles stated above,the rule of the damage degree to the reservoir is presented as SRB>TGB>IB,SRB should be used as the key control index.For the ultra-low permeability reservoir,the microbial controlling indicators in the injected water were recommended.

    • 摘要: X油田特低渗透油藏储层平均埋藏深度2300 m,平均渗透率仅为2.1 mD,在开发过程中多数断块单井日注水低于15 m3,采油速度低于0.3%,严重制约该类油藏的规模上产.为实现该类储层的有效注水开发,引入了大规模压裂技术,在对大规模压裂提高单井产量及缩小注采井距主要机理研究的基础上,进行了压后水驱动态模拟,确定了大规模压裂井具有初期产量高、注水受效快、见效后含水上升快的水驱开发特征.针对压后水驱开发特征,提出了"邻井错层、隔井同层"的压裂方式及压后提压与周期注水相结合的注水能量补充方法.研究表明:大规模压裂技术可使单井产量提高至常规压裂的2.0倍,通过压裂设计及注水补充能量方式的优化可使水驱采收率提高至26%,实现了特低渗透油藏的有效注水开发.%The average reservoir burial depth of extra low permeability oil reservoirs in X Oilfield is 2 300 m and their average permeability is only 2.1 mD. And in the process of development, the single-well daily water injection is lower than 15 m3in most fault blocks and the oil production rate is lower than 0.3%. Thus, the large-scale produciton increase of extral low permeability oil reservoirs is restricted seriously. In this paper, the large-scale fracturing technology was introduced to realize the effective water flooding devel-opment of extral low permeability oil reservoirs. After the main mechanisms of increasing single-well production rate and decreasing injection/production well spacing by large-scale fracturing were investigated, the dynamic simulation of postfrac water flooding was estabished. It is confirmed that large-scale fracturing wells have the following water flooding development characteristics, i.e., high pro-duction rate in the early stage, fast water flooding response and fast rising of water cut after the response. In view of these characteristics of postfrac water flooding development, it was proposed to adopt the fracturing mode of "different layers in neighboring wells and the same layer in interval wells" and implement the water flooding energy implement method which combines postfrac pressure boosting with cyclic water flooding. It is indicated that the single-well production rate after the application of large-scale fracturing techlogy is 200% that of conventional fracturing, the water flooding recovery factor is increased to 26% based on the optimization of fracturing design and water flooding energy supplement mode, and thus extra low permeability oil reservoires can be developed effectively by means of water flooding.

    • 摘要: 高压压汞、恒速压汞、核磁共振实验在表征特低渗透砂岩储层的微观孔隙结构时存在局限性,其结果与铸体薄片和扫描电镜观察到的特征吻合度不高.为了解决这一问题,更加精细地刻画孔喉分布特征,以鄂尔多斯盆地合水地区砂岩储层样品为例,提出了多方法协同表征全孔径孔喉结构的方法.利用高压压汞所得毛管压力曲线与核磁共振联合高压压汞计算所得的伪毛管压力曲线对比,根据喉道分类分别计算吸附喉、微喉、细微喉、中细喉对应的孔隙空间的连通比.根据核磁共振实验原理,利用公式实现横向弛豫时间向孔径的转换,公式中比表面积利用高压压汞计算,弛豫率利用恒速压汞对比核磁共振T2谱标定,将协同计算所得孔喉分布结果与对应的孔喉连通比相乘得到不同尺度喉道及孔隙连通空间分布曲线.结果显示:吸附喉连通比最低,其他类型的喉道连通比较高,且差异不大.喉道分布范围(0.003~3.661μm)较恒速压汞结果变大,孔隙半径(0.8~91.4μm)减小,孔喉比(16.4~58.6)减小,与铸体薄片与扫描电镜观察结果基本相符.说明多种方法协同计算一定程度上克服了高压压汞喉道与孔隙的叠加以及恒速压汞的计算误差,更接近于储层真实状态.
