摘　　要：塔南凹陷铜钵庙组与南屯组储层含大量凝灰质,由于其具有较强敏感性,钻井过程中极易受到地层损害。为解决这一问题,以该区储层特征为基础,通过对岩心进行水敏性、速敏性、盐敏性、酸敏性和碱敏性室内实验,对该类储层进行系统研究。研究结果表明,该类储层具有较强的水敏性、中等偏弱-弱-无速敏性、中等偏强的盐敏性和强-中等偏强的酸敏性,无碱敏性。该实验研究为钻井过程中的油层保护提供了理论依据。The rock type of Tongbomiao and Nantun formations in Tanan depression mainly comprises pyroclastic rock,which is different from common sandstone reservoirs and contains substantial tuffaceous matters.This paper studies the sensitivity of the tuffaceous reservoir through experiments of water sensitivity,velocity sensitivity,salt sensitivity,acid sensitivity and alkali sensitivity.The results show that such reservoirs have certain water sensitivity,velocity sensitivity and salt sensitivity,and extensive acid sensitivity,but have no alkali sensitivity.
