| 摘 要： | 大宛齐油田新近系库车组油藏含油砂体厚度薄,砂体规模小,该井区油井生产均采用衰竭式、多层合采方式,层间矛盾突出,影响了开发效果。结合该区油藏地质及生产特征,采用正交试验设计方法,通过数模技术研究单因素影响程度,认为大宛齐油田多层油藏合采时影响单层采收率的控制因素主要为水体能量,其次为砂体延伸长度和砂体厚度；而单层产量贡献的控制因素主要为砂体延伸长度,其次是砂体厚度和水体能量。据此提出砂体分类、精细注水、分级补充能量的开发对策。

| Abstract: | Oil reservoir of Neocene Kuqa Formation in Dawanqi Oilfield features in thin oil-bearing sandbody and small sandbody size. Blowdown depletion and multi-layering production are adopted for well production, which causes great layering paradox and interference. Based on the geological and development characteristics, this paper uses orthogonal experiment designing method and studies the recovery controlling factors with numerical simulation method. The results show that the main controlling factors of the single-layer recovery are aquifer energy, sandbody length and formation thickness sequentially, while the main controlling factors of the absolute layer production are sandbody length, formation thickness and aquifer energy sequentially. Based on this, such development method of sandbody classification, fine injection and grading energy supplying is proposed. |
