    • 摘要: 随着持续几十年的注水开发,大庆油田已逐渐步入高含水甚至特高含水阶段,油藏及流体的非均质性使优势通道更加发育,大量剩余油多集中在平面弱波及区域,如何进一步深入挖潜平面剩余油已成为矿场EOR(强化采油)的主要矛盾.在聚驱开发基础上,运用非均质油藏的数值模拟及平面物理模型的室内驱替实验,提出了控制采油井流压进一步改善平面开发矛盾的方法.研究结果表明:流压调整需充分考虑聚驱过程油墙富集的影响,在低含水期流压调整可使剩余油动用更加均匀,流压调整需考虑层内物性等因素,并形成了"含水下降期流压略微提升,低含水期反向调整,含水回升期恒定调整"的调整模式.该调整模式应用于矿场效果较好.

    • 摘要: Aiming at the problem of reasonable formation pressure and reasonable flow pressure in low permeability oilfield , the variation law of formation pressure under different water cut ,recovery degree and injection‐production ratio was studied ,a new method for calculating reasonable formation pressure was established ,and the rational strat igraphic pressure range and the adjustment of pressure system in each block in Pubei area was obtained.Considering the effect of water content and liquid production on correcting the actual IPR curves of each fault block in Pubei area the reasonable flow pressure range of each fault block was calculated ,the correction equation of inflow performance under various connected conditions of single well in Pubei area was established ,and the reasonable flow pressure range of some single well was calculated.The results show that the evaluation method of formation pressure and flow pressure is more reasonable.According to the calculated minimum reasonable formation pressure and the minimum reasonable flow pressure of each fault block ,the oil increasing effect of the adjustment well is obvious and the formation pressure tends to be reasonable.The gas influences of the wells were well controlled and the pump efficiencies were improved by adjusting flow pressure.%针对低渗透油田合理地层压力保持水平及合理流压界定等问题,开展了不同含水率、采出程度和注采比下的地层压力变化规律研究,建立了合理地层压力计算新方法,给出了葡北地区各区块合理地层压力范围和压力系统调整意见.考虑含水率和产液量影响,修正了葡北地区各区块IPR实际曲线,计算了各区块合理流动压力范围,建立了葡北地区单井各种连通情况下流入动态修正方程,计算了部分单井合理流动压力范围.结果表明,研究的地层压力和流动压力评价方法更合理,依据计算的各区块最小合理地层压力及最小合理流动压力开展的压力系统调整井增油效果明显,地层压力趋于合理;通过调整流动压力井的气影响得到有效控制,泵效得到了提高.

    • 摘要: 大庆外围油田随着开发的进行油层出现了不同程度的污染,同时由于流动压力的不合理,导致了多数采油井处于低于饱和压力条件下开采.针对这一现象,本文以一种井下关井测压工艺在低渗透油田的应用为例,探讨了井下关井测压工艺缩短产油井出现径向流时间的可行性.应用效果表明:井下关井测压工艺能够降低井筒储存效应,可以明显缩短产油井压力恢复时出现径向流的时间.

    • 摘要: 为了降低苏里格气藏苏25区块新井建产地质风险,提升区域Ⅰ+Ⅱ类井钻井比例,针对该区气藏“低孔隙度、低渗透率、低地层压力、低含气丰度、含气砂体厚度和分布变化大”的特点,需要开展井位优化部署方法研究.在系统整理试气资料的基础上,分析累计产量与无阻流量、套管压力、油管压力、静止压力、流动压力等参数之间的关系发现,求产初期地层流压与平均年产量具有较好的相关性,在原有区域井位优选方法的基础上,结合井底流压与单井平均年产量的相关关系,把求产初期地层流压与换算好的单井平均年产量分别绘制成等值线图并进行叠合,提出了区域“流压—平均年产量”井位部署方法.经过实际应用,该方法实施效果良好,Ⅰ+Ⅱ类井钻井比例明显增加,提高了单井控制储量和气田的采收率.

    • 摘要: Traditional IPR curve test is characterized by severe influence on time-rate, less curve number, poor applicability, etc.A new method is proposed to gain IPR curve based on periodic production data and 5-category IPR curves are summarized, namely negative-correlation, near-horizontal, positive-correlation, near-vertical, cluster.Research indicates that negative-correlation IPR curve presents relatively stable formation pressure and a specific relationship between daily liquid production and bottom-hole flowing pressure.Near-horizontal and positive-correlation IPR curves indicate change in periodic formation pressure and the daily well liquid production is dependent on both static pressure and bottom-hole flowing pressure.Near-vertical IPR curve shows a mismatching between lifting capability and liquid production capacity and the lifting capacity is less than the theoretical formation liquid production capacity.Cluster IPR curve reveals a stable periodic production without specific relationship between daily liquid production and bottom-hole flowing pressure.The liquid production capacity of production well, formation pressure trend, lifting condition can be determined according to distribution of production data in IPR, which could provide certain guidance for injection-production adjustment.%针对传统IPR曲线测试影响时率、曲线数量少、矿场应用范围小等问题,提出了利用油井阶段生产数据制作IPR曲线的方法,并归纳出了负相关型、近水平型、正相关型、近垂直型、簇型等5种IPR曲线类型.研究表明:负相关型IPR曲线反映井区地层压力相对稳定,日产液量与井底流压关系明确;近水平型、正相关型IPR曲线反映阶段地层压力存在变化,日产液量受静压、流压变化共同影响;近垂直型IPR曲线反映井下举升能力小于地层理论产液能力,举升工况与产液能力不匹配;簇型IPR曲线反映阶段生产状况稳定,但日产液量与井底流压的相关性不明.结合生产数据点位于IPR曲线的位置,可对油井产液能力、地层压力变化趋势、举升工况合理性做出判断,指导井区注采调整.

    • 摘要: 针对储气库井油管弯曲段气蚀严重的问题,利用k-ε湍流模型,通过理想气体状态方程确定了油管内天然气流动的初始条件和边界条件,基于有限元方法,研究了不同注气速度、弯曲角度等对油管任意截面位置处静压、波动压力、速度场分布的影响规律。结果表明:储气库油管内压力波动大小与注采气密度、速度等相关,且与注采气速度平方成正比;在油管弯曲段由于能量的急剧转化导致油管内压力出现波动,而垂直段和水平段内压力变化较为平缓,弯曲段油管B点压力波动程度较A点明显降低,而该截面静压分布则刚好相反,且油管内压与注气速率之间呈现非线性关系。
