随着大型油田的大规模开发,到油田开采的中后期,许多油田的油藏都呈现出过度分散的特征,传统的钻井方式很难挖掘这些资源。侧钻井技术利用地上和地下的原有资源可以实现高效低成本开发,对于开采老区剩余油有极大的优势。侧钻井技术在国外已经有成熟的技术和配套设备,国内技术性对比较落后,本文首先简单介绍了国内外的技术现状,然后介绍了侧钻井技术的完井技术和采油技术两个方面。
With the large-scale development of large-scale oilfields, oil reservoirs in many oilfields are characterized by over-dispersion in the middle and later stages of oilfield exploration. The traditional drilling methods make it difficult to mine these resources. Side drilling technology using the original resources above and below the ground can achieve efficient and low cost development, which has great advantages for the remaining oil in the old mining area. Side drilling technology in foreign countries already have mature technology and ancillary equipment, the domestic technical backwardness, this paper first briefly introduced the status quo of technology at home and abroad, and then introduced the side-drilling technology completion technology and oil production technology in two aspects.
