    • 摘要: 大庆油田现阶段已经进入特高含水期,油田开采面临诸多困境,且由于地层能量不足、单井含水较高、套损等因素影响,造成一些井连续停产长达十年之久,形成了长关井.这些长关井的存在不仅使油水井利用率降低,而且还使区块注采系统不完善,储量动用不均衡,直接影响区块整体开发效果,造成油田资产浪费,并产生一定的安全环保风险.治理长关井,恢复生产,是老油田提质增效的重要手段.依据大庆油田某后续水驱区块的长关井现状,根据关井原因,通过注采调整、补孔等技术手段进行综合治理,使之复产增油.

    • 摘要: 为解决南海西部W油田采油井结垢问题,在结垢机理及危害认识基础上,结合历年结垢采油井治理措施效果和油井高含水的现状,从油藏角度提出RPD(RPM测井、补射孔、除防垢)综合治理技术,实现释放产能、控水稳油、暂缓结垢三重治理效果.W油田共计在两口井应用了 RPD治理措施,平均单井有效期809 d,为历史措施平均值631%,平均单井累计增油量3.11×104 m3,为历史措施平均值507%.该方法对海上及陆地油田结垢油井的治理具有重要指导意义.

    • 摘要: 油田在开发过程中,随着原油被举升至地面,外界温度、压力、流体流速等因素的变化会引起无机盐类在油井管壁或地层上形成沉积,造成油井结垢。油井结垢可以堵塞射孔孔道和地层孔隙,降低地层渗流能力,从而引起产液量下降等问题。为了解决以上问题,开发了同层段定方位二次射孔技术。

    • 摘要: 气田产出水具有高浊度、高矿化度、高腐蚀性、高含铁量、低pH值等特点,气田产出水不能注入生产层位影响天然气开采,需选择物性好的非生产层位进行回注.回注水中固体的悬浮物会堵塞地层,造成回注压力过高,为了缓解污水处理能力不足,确保采气系统顺利运行,根据大牛地气田的实际情况,开展酸洗、重复压裂、补孔等措施,制定适合回注井的有效措施并进行现场推广应用.

    • 摘要: The time or opportunity of perforations adding (i.e.the watercut for the perforation added oil well) for the low-saturation oil layer at the high water cut stage is of great significance for improving the multi-reservoir recovery degree.By means of the seepage theory and reservoir engineering methods,the mathematical flow model was established for the perforations adding of the high-watercut low-saturation multi-layer oil reservoir with the barriers;under the conditions of different dimensionless initial oil saturation,the dimensionless water injection rate,the dimensionless permeability and the dimensionless thickness,the influences of the time on the recovery degree were studied with the help of the model.And moreover the optimal adding time was obtained.The research achievements show that with the increase of the adding time,the recovery degrees of 98% comprehensive watercut and after 3 years of perforations adding increase as well;when the perforation time is more than 85%,with the reduction of the perforation adding,the increments of the degrees stated above also increase.The greater the different dimensionless initial oil saturation,the dimensionless thickness and the dimensionless permeability are,the higher both the recovery degrees will be;the greater the dimensionless velocity of the water injection is,the greater the recovery degree after 3 years will be;the dimensionless speed of the water injection does not affect the recovery degree of 98% comprehensive watercut.The study concludes show that taking the recovery of 98% comprehensive watercut as the goal,92%-96% watercut is regarded as the best for the time of the perforation adding;taking the recovery after 3 years as the goal,the velocity of the water injection should take as higher as possible,the time of the perforation adding should also take 92%-96% of it as the best.%高含水期低饱和度油层补孔时机(补孔时油井的含水率)对提高多层油藏高含水期采出程度有重要意义.运用渗流理论及油藏工程方法建立了存在隔层的多层油藏高含水期低饱和度油层补孔渗流数学模型;并运用该模型研究了不同无因次初始含油饱和度、无因次注水速度、无因次渗透率及无因次厚度条件下,补孔时机对采出程度的影响,并给出了最优补孔时机.研究结果表明:随着补孔时含水率的增加,综合含水率98%采出程度与补孔 3年后采出程度均增加;当补孔时含水率达到85%后,随着补孔时含水率上升,综合含水率98%采出程度与补孔3年后的采出程度增加幅度均变大;无因次饱和度、无因次厚度、无因次渗透率越大;综合含水率98%时的采出程度与补孔3年后的采出程度越大;无因次注水速度越大,补孔3年后采出程度越大;无因次注水速度不影响综合含水率98%的采出程度.研究结论:以综合含水率98%的采出程度为目标时,补孔时含水率取92%~96%为最佳;以开发3年后的采出程度为目标时,注水速度应在工程允许范围内尽量取大,补孔时含水率取92% ~ 96%为最佳.
