川西南矿区由于勘探程度很高,勘探难度逐年增加。本文介绍了该矿区近两年来,根据二叠系阳新统断层裂缝圈闭气藏勘探的需要,利用钻井工程手段打准井底50m半径地质靶区,提高勘探成功率的钻井实践。

Using the Means of Drilling Engineering to Raise Exploration Success Ratio

As the exploratory level of Southwest Sichuan Mine is more higher, the exploration difficulties are added year by year. According to the exploration need of fault fissure trap gas reservoirs in Yangxin Series of Permian, it is described in this paper that the Mine in recent two years accurately drills the ge- ologic target area within a radius of 50m in bottom hole by using the drilling engineering recalls and raises exploratory Success ratio.
