涪陵大安寨页岩油气藏表面活性剂改善贾敏效应实验研究

摘要

近几年来，随着天然气价格急剧上涨、开采技术不断进步，我国逐渐把页岩气开发作为未来勘探开发的重要目标。但在开发过程中，贾敏效应对油气藏开发影响很大，然而在目前技术条件下消除贾敏的影响很难实现。因此，文章采用表面活性剂研究减轻贾敏效应影响来提高采收率。%In recent years ,with the natural gas prices rising sharply and the developing trend of mining technology in China ,shale gas de-velopment has become an important objective of future exploration and development .However ,in the development process there is great im-pact of Jamin effect on the oil and gas development ,it is difficult to eliminate with current technology .Therefore ,this paper makes a re-search on surfactants mitigating the Jamin effect to improve oil recovery .
