摘要
针对克拉玛依油田六东区克下组油藏原油粘度较高、注水开发效果差的现象,从开采机理、国内外实例、油藏自身条件等方面对其转注蒸汽开发进行了可行性分析;应用油藏工程方法和数值模拟技术,对转注蒸汽开发层系划分、合理井网井距设计和开采方式、注采参数确定以及不同油层厚度转注蒸汽开发效果进行了研究。提出了转注蒸汽开发方案,经现场实施,取得了良好的效果。
In view of high viscosity of crude oil and poor waterflooding performance in Lower Karamay formation in east District No.6 Karamay field feasibility study was conducted on the conversion to steam injection in terms of production mechanism case history from home and abroad and reservoir conditions. By applying reservoir engineering and numerical simulation the authors studied the classification of target layers establishment of reasonable well pattern and spacing determination of recovery method and injection production parameters and performance of steam injection of different net pay. The paper also presents steam injection scheme. Case study showed that it performed well.
