摘要
从储层伤害的机理出发,结合修井液的特点对其造成的储层敏感性伤害进行了分析,分别从减少修井液的固相和液相伤害进行了体系构建。结合实验研究研制出了封堵性能好、抑制性强、易返排、储层保护效果优异的修井液技术体系及配套完井液;并以南海西部乐东15-1气田为目标区块进行了现场应用。结果表明,该技术系列能够有效地保护油气层,提高修井作业后的产量恢复效率,效果十分显著。
From the mechanism of reservoir damage,according to the analysis of characteristics of workover fluid for reservoir sensitivity,a protecting formation workover fluids derived from reducing solid and fluid phases damage relatively was constructed. The experimental research result indicated that this systems have a good sealing performance,strongly inhibition performance,easy flowback and excellent reservoir protection technology during workover process,combined with the application of LD15-1 as target oilfield district,field application results show that the system can effectively protect the reservoir,promptly enhance the production rate after operation.
