由于注水水质等问题,造成注水井管柱结垢严重,尤其造成分注井测调遇阻率不断攀高,并且随着分注井数的持续增多,使这一情况持续恶化,带来小层注水量失控,只能通过常规及带压检串进行治理,所需费用巨大,已严重影响到了油藏的高效开发,给正常生产和成本控制带来了空前的压力。本文结合胡尖山油田注水井结垢的实际现状,提出解决及缓解目前注水井管柱的思路和对策。
As a result of water quality problems, resulting in a serious injection of water well pipe scaling, in particular, caused by the injection well test met resistance rate continues to rise, and with the number of wells continued to increase, so that the situation continued to deteriorate, bringing a small layer Water loss is out of control. It can only be managed by conventional and pressure-tested bunches. The cost is huge. It has seriously affected the efficient development of oil reservoirs, putting unprecedented pressure on normal production and cost control. In this paper, the actual situation of water injection wells scaling in Hujian oilfield is put forward to solve and mitigate the current ideas and countermeasures of water injection well strings.
