摘　　要：分析了准噶尔盆地小拐断块Ｊ１１，Ｔ１ｚ，Ｐ２ｘ的储层特征及潜在损害因素。根据分析结果，提出在该区块采用油溶性树脂屏蔽暂堵技术来保护油气层的方案。研制了适用的暂堵剂——ＪＨＹ油溶性树脂和适合于该区块的钻井液体系，并评价了该体系对油气层的损害程度和深度。结果表明，所研制的钻井液体系能较好地实现油溶屏蔽暂堵，有效地保护油气层。例如，其动态损害评价的渗透率恢复值大于６５％，静态损害评价的渗透率恢复值大于７０％。In Junggar basin, the reserviors J11, J12, P2x in the Xiaoguai faulted block are important oilgas formations Firstly, the characteristics and potential damage factors for these reserviors are analyzed and then, an oilsoluble shielding temporary plugging technique is suggested to protect oilgas formation A drilling fluid system suitable to this area is developed and the degree and depth of formation damage caused by this drilling fluid is assessed Tests indicate that this drilling fluid system is capable of realizing oilsolube shielding temporary plugging and protecting formation effectively For example,the restoration of permeability is over sixtyfive percent in dynamic damage test and over seventy percent in static damage test 
