大庆龙西油田高台子油层为一高含泥低渗透油藏．为高效开发该油田，从研究油层的敏感性着手，系统研究了入井流体对油层岩心的伤害，提高了使用强抑制复合离子聚合物水基钻井液、 Ｐ Ｔ Ａ 和 Ｋ Ｃｌ保护射孔液、 Ｂ Ｃ Ｓ－ ８５１ 瓜胶压裂液、 Ｋ Ｃｌ保护修井液及综合注水质控制等系统技术，大大提高综合开发效宜．
Daqingzi Longxi Oilfield reservoir is a high muddy, low permeability reservoir. In order to develop this oilfield efficiently, the paper studies the damage of oil in the reservoir core by studying the sensitivity of the oil layer, and improves the use of water-based drilling fluid with strong inhibitory effect of composite ionic polymer, P T A and K Cl protection perforating fluid, B C S- 851 guar fracturing fluid, K Cl protection and workover fluid and integrated water quality control system technology, greatly enhance the comprehensive development effectiveness.
