套管开窗侧钻水平井技术应用于老油田套损井综合治理和老区剩余油挖潜改造，对开发未受控面积内的储油和死角残余油效果明显；应用于低渗透、薄油层，可有效提高单井产量和采收率。要保证侧钻水平井的工艺效果，必须仔细研究油井地质状况，制定完善的施工方案和适宜的完井方式，使之充分满足后期开发作业的要求。
套管開窗側鑽水平井技術應用于老油田套損井綜閤治理和老區剩餘油挖潛改造，對開髮未受控麵積內的儲油和死角殘餘油效果明顯；應用于低滲透、薄油層，可有效提高單井產量和採收率。要保證側鑽水平井的工藝效果，必鬚仔細研究油井地質狀況，製定完善的施工方案和適宜的完井方式，使之充分滿足後期開髮作業的要求。

The application of case overshot for sidetrack drilling horizontal welltechnology in overall managing casing damage wells and tapping the potential remainingoil in the maturing oilfield has got obvious effects on opening up the oilstorage in uncontrolled areas and residual oil in dead space, while itsapplication inless permeable and thin oil paylayer may increase single well production and recovery. To guaranteetechnology effects of sidetrack horizontal well requires making a careful studyof geological condition about oil wells and deciding a sound operational planand a proper well completion pattern to fully meet the demand for later perioddevelopment operation.
