摘要:
NH201区块高气油比原油在举升过程中脱气后造成井筒结蜡,严重影响生产。为治理油井结蜡,以油井信息化建设为依托,逐步形成了以示功图和有功功率双参数组合为主的结蜡预警工艺、以油井自循环热洗井和自动化密闭加清蜡剂为主的结蜡预防工艺、以调快冲次生产和解卡自救为主的蜡卡处置工艺。现场应用表明,清防蜡工艺的实施显著降低了蜡卡井次,节约了平均处置时间和清防蜡成本。2020年以来,未出现因蜡卡导致检泵作业的情况,平均处置时间由4 d下降至3 h,年减少产量损失超300 t,节约成本45×104元。
Abstract:
High gas-to-oil ratio crude oil in NH201 Block caused wax formation in the wellbore after degassing during the lifting process,which seriously affected production. To control the paraffin formation of oil wells,based on the construction of oil well informatizations,we have gradually formed the wax formation early warning technology based on the combination of dual parameters of work diagram and active power,the wax formation prevention technology based on self-circulation hot washing of oil wells and automatic confinement with paraffin removal agent,and the wax card disposal technology based on adjusting the number of wells with fast stroke production and self-rescue of paraffin. Field application shows that the wax removal and prevention process significantly reduces the number of wax-stuck wells,and saves the average disposal time and the cost of wax removal and prevention. Since 2020,there has been no case of pump inspection operation caused by wax card,the average disposal time has dropped from 4 days to 3 hours,the annual production loss has been reduced by more than 300 tons,and the cost has been saved by 45×104 yuan.
