摘要: 牛心坨油田20年注水开发,平面和层间的注水矛盾突出,急需进行吸水剖面调整,尤其是深度调剖。利用现有的调剖剂体系进行调剖改善,成胶效果差,调剖效果不理想。经调研发现调剖剂中溶解氧的存在是破坏调剖成胶效果的主要因素。通过现场提供的聚合物、交联剂和水样品,利用油田常用除氧剂对牛心坨油田调剖剂成胶改善效果开展了一系列室内实验研究。结果表明,苯甲酸钠和硫代硫酸钠对于改善调剖剂成胶有一定的效果。

Abstract: In the 20 years of waterflood development in the Niuxintuo oilfield, the contradiction between water injection in plane and interlayer is prominent, so it is urgent to adjust the injectivity profile, especially for depth profile control. Using the existing profile control agent system to improve the profile control, the effect of gel formation is poor, and the profile control effect is not satisfactory. It has been found that the presence of dissolved oxygen in the profile control agent is the main factor affecting the effect of profile modification. The site provides the polymer, crosslinking agent and water samples, the use of commonly uses deoxidant on Niuxintuo oilfield profile control agent to improve the effect to carry out a series of laboratory experiments.The results show that sodium benzoate and hyposulphite for improving the effect of gumforming compound have certain effect.

Key words: Niuxintuo oilfield, Profile control agent, Deoxidant, Influence factors, Experimental analysis
