摘　　要：轮南油田1992年投入开发,目前部分油藏已进入特高含水开发阶段,经过20a的开采,剩余油分布高度分散,油水关系极其复杂,单井平均日产逐年下降,地下油水体系与开发初期有了极大的不同,加密井在钻井与生产过程中受到各方面条件的制约,极易受到污染从而严重影响单井产量。通过对取心井LN2-22-H2井储层敏感性进行实验评价,储层速敏类型为弱速敏,水敏类型为中偏弱水敏和弱水敏,盐敏类型主要为中偏弱盐敏,其次为弱盐敏和无盐敏,酸敏类型主要为无酸敏,其次为弱酸敏和中偏弱酸敏,碱敏类型主要为中偏弱碱敏和无碱敏。Tarim basin Lunnan oilfield was placed on production in 1992, and part of reservoir already attain extra high water content development phase. After decade years of exploitation, remaining oil distribute disperse highly, the relationship of oil and water is complex, single well average daily capacity drop year by year, subsurface oil - water system different from beginning of development, infill well is subjected to pollution and affect seriously yield because of various sides in the process of drilling and production. Reservoir sensitivity of LN2 - 22 - H2 well Trias- sic are evaluated, the type of velocity sensitivity is weak, the type of water sensitivity is medium - weak and weak, the main type of salt sensitivity is medium - weak salt sensitivity. Followed by a weak salt sensitivity and no salt sensitivity, the main types of acid sensitivity are none. Followed by weak and medium - weak acid sensitivity, the main type of alkali sensitivity is medium - weak and no alkali sensitivity. This paper provides useful suggestions for reservoir protection in the secondary development of Lunnan oilfield.
