摘要
马北一号油藏规模小、含油带窄、边底水发育,早期开发采取一套不规则基础井网控制主力油层、边认识边布井的开发模式,油井投产后普遍出现地层能量较弱、含水上升快、产量递减迅速等问题。针对油田开发现状,应用灰色综合评价技术对油田水驱开发潜力地质影响因素和开发效果进行评价,在油藏剩余油、加密调整潜力分析基础上,基于数值模拟技术,有针对性地转变油藏开发模式,调整层系井网,充分动用挖潜油藏剩余油。研究表明,调整对策能有效减缓含水上升和产量递减速度,改善油藏开发效果。
The MB1 reservoir is a small reservoir with narrow oil-bearing zone and edge-bottom water. In early development period, an irregular basic well pattern was used to control the main layer and wells were placed while understanding. After putting into production, oil wells generally showed problems of insufficient formation energy, rapid increasing of water cut, and rapid production decline. The geological influence factors and development response of waterflooding have been evaluated by grey comprehensive evaluation technology according to current development performance. On the basis of analysis of remaining oil and infilling adjustment potential, the reservoir development model is converted accordingly based on numerical simulation to adjust well pattern and produce remaining oil. The results indicate that this adjustment strategy has effectively slowed down water cut increasing and production decline, and has improved reservoir development effect.
