姬塬油田吴仓堡区长6油藏为典型的低渗、低压、低产油藏,沉积相类型为湖盆三角洲沉积体系,在构造上处于陕北斜坡中西部,为一平缓的西倾单斜。开发初期为实现和确保该油藏的持续稳产和高效开发,在精细刻画储层微相的基础上,制定出适合该区储层特征的高效开发模式及分层注水开发技术政策。吴仓堡区实施目标差异化管理:分油藏、分开发阶段、分区域进行动态分析,实施以来取得一定的效果。本文主要从注水开发技术政策实施以来油藏动态变化进行分析,分区域评价注水开发实施效果,最终得出目前适应吴仓堡区不同区域合理的注采方式,并对目前困扰和影响该油田高效开发和持续稳产的因素,提出了下步的稳产思路和注采调整建议。
The reservoir of Changbu-6 reservoir in Wuyuanpu, a Jiyuan oilfield, is a typical low-permeability, low-pressure and low-productivity oil reservoir. The sedimentary facies is a basin-delta sedimentary system and is structurally located in the central and western parts of northern Shaanxi. oblique. In the early stage of development, in order to realize and ensure the stable and efficient development of this reservoir, based on the fine characterization of reservoir microfacies, an efficient development mode and stratified water injection development technical policy suitable for the reservoir characteristics in this area were worked out. Wucangbao District, the implementation of the target differential management: sub-reservoir, sub-regional development phase, dynamic analysis, implementation has yielded some results. This paper mainly analyzes the dynamic changes of reservoirs since the implementation of the technical policy of waterflooding development and evaluates the implementation effect of waterflooding development by subregion. Finally, it draws a reasonable way of adapting to injection and production in different regions of Wucubu district at present, Development and sustained steady production factors, put forward the next step of steady production ideas and suggestions for adjustment of production and injection.
