油田开发进入中后期,随着含水的上升,油井结垢矛盾凸显,结垢引起球座漏失、垢卡、管网堵塞、站内设备堵塞成为制约生产运行的棘手问题。球座漏失、垢卡一般通过检泵维护作业恢复产能,结合检泵作业对井筒开展化学防垢配套,能够有效抑制油井结垢。集输管网设备一般采用传统酸洗清垢,具有易造成金属损伤缺失,产生有毒有害气体,无法酸溶硫酸钡锶垢的缺陷。介于此,复合物理清垢工艺应运而生。 Oilfield development enters the middle and late stages. With the rise of water content, the contradiction between well fouling is prominent. The fouling causes ball seat leakage, fouling, pipe network blockage, and blockage of station equipment, which becomes a thorny problem that restricts production and operation. Ball seat loss, fouling card generally through the pump maintenance operations to restore production capacity, combined with the pump operation of the wellbore chemical anti-scaling support, can effectively inhibit the well scaling. Collection and transmission network equipment commonly used traditional pickling dirt, with easy to cause the loss of metal damage, produce toxic and harmful gases, can not be acid-soluble barium strontium sulfate defects. Between here, the complex physical cleaning process came into being.
