摘要
低渗透油田油井的井筒防垢工艺中,需要在保证防垢针对性和效果的前提下,尽可能延长防垢有效期和降低日常管理难度。针对低渗透油田油井产液量低、多井且人工加注频繁、综合成本相对高和管理难等问题,首次在国内开展了A型胶囊防垢剂的物化性能、释放速度和防垢效果等系列评价研究。通过4口油井的现场实验,提出了此类防垢剂技术的适应井况、评价方法和下一步研究方向。
Abstract
In order to control the downhole scale problems of oil well,it is necessary to prolong the validity period of scale prevention and reduce the difficulty of daily management.In the light of the issues of low fluid output,large number of wells,frequent artificial injection and relatively high cost in low permeability oil fields,the evaluation experiments are carried out on physico-chemical properties,release velocity and scale inhibition effect of A-type capsule scale inhibitor.Furthermore,the adaptability,evaluation methods,and next research directions of this type of scale inhibitor technology have been proposed after on-site tests on four oil wells.
