本文针对目前套管加药需要放掉套压,由套管一次倒入一至二桶药剂的方式,一是放套压后,造成油井生产压差的变化,影响油井正常生产甚至躺井;二是一次性倒入药剂,作用时间短,增油效果差,并造成药剂的浪费。针对这个问题我们研制了通用套管连续加药装置。根据连通器压力平衡原理,采用外加储药罐的方式,用平衡管平衡罐体与套管内压力,罐内药剂依靠重力流入井底;同时加装调节阀调整药剂流入速度,实现带压连续加药。
In this paper, the current need to let go of cannula dosing nesting pressure, the casing poured into one or two barrels of drugs at a time, one is placed after the pressure, resulting in pressure changes in well production, affecting the normal production of oil well or even lie well; Is a one-time infusion of pharmaceutical agents, the role of a short time, poor oil, and resulting in waste agents. In response to this problem we developed a universal cannula continuous dosing device. According to the principle of pressure balance of the communicator, an external storage tank is adopted to balance the pressure in the tank and the casing with a balance pipe, and the medicament in the tank flows into the bottom of the well by gravity; meanwhile, a regulating valve is installed to adjust the inflow speed of the medicament, medicine.
