摘要
三塘湖油田西山窑组为"低孔、低渗、低压、高粘"复合圈闭砂岩油藏,属于辫状河-三角洲前缘沉积,成南北向带状分布,储层非均质性强,开采难度较大。通过对该油田地质特征的分析,结合不同井网的实际生产情况、应用数值模拟技术合理优化井网类型,从而为新区开发提供了理论基础。
The Xishanyao Formation in the Santanghu Oilfield is a reservoir characterized by ＂low porosity, low permeability, low pressure and high viscosity＂ and belongs to braided river-delta front facies. This paper deals with geological features of the oilfield and optimization design of well pattern based on numerical simulation.
