摘要
在水驱油田开发中后期,多轮次调剖是一项重要的稳油控水措施。本文提出了高含水期油藏三维三相多轮次调剖数学模型,研制出多轮次调剖模拟器。模拟器中综合考虑了堵剂驱油过程中的物理特性,并使用了局部网格加密技术,为高含水期油藏进行多轮次调剖油藏工程方案研究提供了有力的工具。并结合实际生产情况,对一试验区块进行了多轮次调剖油藏工程方案研究,研究了调剖时机、堵剂用量对调剖效果的影响。
In the late stage of water flooding, multi-round profile control is an important measure to stabilize oil production and control water cut. In this paper, a mathematical model for multiround profile control is built, and a numerical simulator with 3D and 3 phases is also proposed. In order to describe the relationship between formation and plugging agents more precisely, a local mesh refinement technique is applied. This simulator provides an effective simulating tool for the research of multi-round profile control reservoir engineering. Using this simulator, the reservoir-engineering project on a practical producing model is researched.
