松南地区复合钻井技术分析

Analysis on Combined Drilling Technology in Songnan Area

摘要:

松南地区地层岩石可钻性级值高,油气勘探过程中面临的关键问题是钻速低,钻井周期长,严重影响了该地区的油气勘探。为了提高该地区的机械钻速，进行了较多复合钻井等提速技术的研究及应用。针对松南地区已开展的复合钻井技术实验进行了分析，分析了复合钻井技术提速机理，以及松南地区开展复合钻井技术适用的地层。

Abstract:

To improve the penetration rate in Songnan area, many speed-up technologies like combined drilling were studied and applied. Based on the combined drilling experiments in Songnan area, analysis was made on the speed-up mechanism of combined drilling and the applicable formations.
