摘要(Abstract)：

喇嘛甸油田将直接面临上返的问题,但二类油层注聚开发合理的注采井距、井网如何优化等都是目前急需解决的问题。通过对喇嘛甸油田二类油层地质特点的精细研究,选取了能够代表喇嘛甸油田二类油层实际状况的喇南试验二区东南部作为解剖区块,开展了数值模拟和井网优化研究,从不同井网与原井网的匹配关系、对砂体的控制程度、注入速度与井距的关系、数值模拟预测以及今后上、下返井网的综合利用等不同角度进行了对比论证,优选出既适应二、三类油层,又能最大限度地提高最终采收率的合理井网、井距,对二、三类油层的井网部署和优化具有指导意义和参考价值。
How to determine reasonable injection-production well pattern and how to optimize well pattern in class II reservoirs during polymer flooding are the problems needed to be solved at right. According to fine research on geologic characteristics of class II reservoirs in Lamadian oilfield, the southeast part of test area II in southern Lamadian oilfield has been selected to carry out numerical simulation research and well pattern optimization research. The selected part can represent the practical conditions of class II reservoirs in Lamadian oilfield. The research concerns of the matching relationship between different well patterns and former well patterns, control extent to sand body, relationship between injection velocity and well distance, numerical simulation prediction, and the comprehensive utilization of upward and downward well patterns. Then the reasonable well pattern, which is not only suitable for class II and III reservoirs, but also improve the ultimate recovery factor furthest, can be optimized. This research is one kind of meaningful reference to well pattern design and optimization in class II and III reservoirs.
