【摘要】：为满足大庆油田不同阶段的水驱开发需求,油田通过几代人的攻关和完善形成了符合大庆油田的分层注水技术系列。但是,目前面对大庆油田进入特高含水开发后期的多层系井网精细开发需要,为有效缓解油田开发中的层间、层内和平面等矛盾,深度挖潜各层系开发潜力,不断提高水驱动用效果,需要进一步精细有效划分注入层段,并确保工艺管柱有效密封和施工安全,因此,需要开展多层细分注水工艺管柱及配套技术研究,设计工艺管柱及配套测调方法,了解工艺管柱的应力应变分布,为油田水驱开发有质量、有效益、可持续的发展目标实现提供技术支持。本文首先根据油田目前需求研究多层细分注水管柱的工艺原理,确定分层注水管柱结构,设计研发配套的工具和配套测调工具;其次开展了注水管柱的受力分析,建立管柱力学模型,获得分层注水管柱力学分析所需的边界条件;并对管柱的实际工况进行分析,确定其计算流程以及边界条件的处理方法,根据管柱力学基本理论进行分层注水管柱力学模拟分析软件的编制,模拟分析分层注水管柱受力,指导分层注水工艺施工,确保注水施工管柱安全。通过上述研究,最终形成了1套适合大庆油田特高含水开发阶段精细分层注水工艺管柱和配套测调方法;开发了1套分层注水管柱模拟分析系统,实现对工艺管柱的受力分析,可为分层注水施工工艺制定提供借鉴和指导,并具备进一步扩展功能;并开展了多层细分注水工艺效果的跟踪分析和评价,获得了显著的开发效果,得到了应用单位和相关部门的认可,证明了开展该项技术攻关研究是十分必要的。
[Abstract]:In order to meet the needs of water drive development in different stages of Daqing Oilfield, the oilfield has formed a series of stratified water injection technology in line with Daqing Oilfield through several generations of key problems and improvement. However, in the face of the need of fine development of multi-layer system well pattern in Daqing Oilfield in the late stage of ultra-high water cut development, in order to effectively alleviate the contradiction between layers, layers and planes in oilfield development, and tap the potential development potential of various layers in depth, In order to continuously improve the water driving effect, it is necessary to further divide the injection layer and ensure the effective sealing and construction safety of the process string. Therefore, it is necessary to carry out research on the multi-layer subdivided injection process string and its supporting technology. The process string and its matching measuring and adjusting method are designed, and the stress and strain distribution of the process string is understood, which provides technical support for the realization of the quality, benefit and sustainable development goal of oilfield water drive development. In this paper, firstly, according to the present demand of oilfield, the process principle of multi-layer subdivision injection string is studied, the structure of stratified water injection string is determined, the matching tool and the matching measuring and adjusting tool are designed, and the stress analysis of water injection string is carried out. The mechanical model of pipe string is established to obtain the boundary conditions needed for mechanical analysis of stratified water injection string, and the actual working condition of string is analyzed, and the calculation flow and the treatment method of boundary condition are determined. According to the basic theory of string mechanics, the software is compiled to simulate and analyze the stress of stratified water injection string, to guide the construction of stratified water injection technology, and to ensure the safety of water injection construction string. Through the above research, a set of fine stratified water injection process string and matching measuring and adjusting method are formed, and a simulation analysis system of stratified water injection string is developed to realize the stress analysis of the process string. It can provide reference and guidance for the construction process of stratified water injection, and has the function of further expansion, and carries out the tracking analysis and evaluation of the effect of multi-layer subdivision water injection process, and obtains remarkable development effect. It has been approved by the application units and relevant departments, which proves that it is necessary to carry out the technical research.
