摘要
针对鲁克沁稠油开采难度大的问题,提出了化学吞吐技术这项新的增产措施,筛选优化了吞吐剂配方,试验结果表明,该配方与鲁克沁地层以及流体配伍性良好,能够有效降低油水界面张力在90%以上,具有较强的乳化降粘能力以及洗油能力,现场作业8井次均获得成功,有效期目前长达13个月,累积增油3207.24t。
To resolve the problem of hard to produce heavy oil in Lukeqing oilfield,presented is the new measurement of chemical stimulation to increase production.The formula of stimulation agent is seized and optimized.Experimental re-sults show that the formula is well compatible with horizons and fluids in Lukeqing oil field with the ability to decrease the surface tension up to 90%,so the formula has high ca-pacity of reducing viscosity by emulsification and oil washing power.In the field,all eight operations are successful with accumulative oil increase as 3,027.24 t and the effective peri-od is as long as 13 months till now.
