Abstract: In general Hanilcatam area of the Tarim Basin, oil and gas reservoirs are deep, the open hole section of second spud is long, and the deep layers are of strong abrasivity with the crossing of competent and incompetent beds. Therefore, the drilling in this area is faced with multiple difficulties, e.g. poor penetration of bits, rapid failure of PDC bits, low ROP and low bid price. To solve these problems, the torsion-impact drilling technology was introduced to increase the ROP and decrease the cost by using high-efficiency rock breaking technology. This technology was tested and applied in 36 wells from 2012 to 2015. It is indicated that it is remarkable in ROF improvement results and economic benefit. The average ROP of hole sections where this technology was tested and applied is 5.74 m/h, which is over 2 folds that of rotary drilling technology and over one fold that of combined drilling technology. And the drilling period of each well is reduced by 25.87 days on average. It provides the technical support for ROP increase and cost decrease of deep and ultra deep well drilling in the platform-basin area of the Tarim Basin

泛哈拉哈塘地区主要包括哈拉哈塘、金跃、跃满、热普等区块，是塔里木油田油气勘探开发的重要区域之一。该地区油气藏理藏深度超过7000m，二开裸眼段长5500m以上，深部地层研磨性强，软硬交错，具有钻头吃入地层效果差，PDC钻头失效快、
寿命短，钻并机械钻速低以及低油价导致的投资减少，中标周期短费用低等特点和难点。为了加快钻井速度，降低成本，在泛哈拉哈塘地区引进了扭力冲击钻井技术【19]，力求通过高效破岩技术有效地消除 PDC钻头在深并、超探深并等难钻地层的黏滑效应，提
