王庄油田沙一段粉细砂岩因敏感性严重,导致该油藏长期处于低效开发状态。对王庄油田敏感稠油油藏进行了油层保护技术的研究,介绍了钻井过程中的油层保护技术、作业过程中的油层保护技术、注汽过程中的油层保护技术。研制和筛选了BPS强抑制性防膨泥浆体系、高效CFP-1和GFP-2常温高温防膨剂及JJ-8降pH值剂,配套了适合王庄敏感稠油油藏钻井、作业及注汽全过程的油层保护技术,现场应用取得了较好的效果。 Wangzhuang Oilfield sand section of fine sandstone due to the sensitivity of serious, resulting in the reservoir in the long-term inefficient development. The paper studies the reservoir protection technology in the sensitive heavy oil reservoirs of Wangzhuang Oilfield, introduces the oil layer protection technology during drilling, the oil layer protection during operation and the oil layer protection technology during steam injection. Developed and screened the BPS strong inhibition of anti-swelling mud system, high efficiency CFP-1 and GFP-2 room temperature high temperature anti-swelling agent and JJ-8 down pH agent, matched for Wangzhuang sensitive heavy oil reservoir drilling, operation and note Steam the whole process of reservoir protection technology, field application has achieved good results.
