摘　　要：文南油田属低渗高油气比油藏,地层伤害严重,主要表现在钻井过程中钻井液漏失及修井、洗井过程中粘土颗粒膨胀运移、入井液固相颗粒堵塞,乳化堵塞以及气井在生产过程中蜡质、胶质、沥青质的析出而造成的有机质堵塞,本文针对文南油田高油气比气井地层伤害原因开展了高油气比井综合解堵工艺技术,该技术熔酸化、热解堵、助排工艺于一体,通过在文南油田高油气比井实施,取得了好的效果,获得了良好的经济效益,为气井解堵提供了一定的指导意义。WenNan oil field is a high gas-oil ratio reservoir. The reservoir damage is serious. , The damage is displayed in the leakage of drilling liquid ,the swell and movement of clay grains in well workover and washing . The paraffin,colloid and asphalum separated out in producing of the gas--well is also a contaminated factor. This article introduces the technique aiming at the contamination in WenNan reservoir ,It combines the hot ,acidification plug remover with cleaning up. Application of this technique has obtained good benefit and social benefit .
