为提高庆深气田侧钻小井眼水平井钻井速度，缩短钻井周期，开展了扭力冲击器配常规导向动力钻具提速技术的研究与应用。首先，重点分析新钻具组合强度是否满足钻进需求，从而防止应力集中造成钻具疲劳破坏；其次，利用扭力冲击器泵压-排量回推公式，优化钻井参数；最后，按照钻具允许的弯曲半径必须小于井眼/套管实际弯曲半径的原则，分析了?215.9 mm和?152.4 mm钻具组合通过能力，从而实现了钻具安全下入，形成了庆深气田扭力冲击器小井眼水平井提速技术，并在宋深9H井成功实施，为加快深层砂砾岩气藏的勘探开发提供了新的技术手段。

In order to improve drilling rate in sidetracking of slimholehorizontal well in Qingshen Gasifeld and shorten drilling pe-riod, research and application has been conducted on the technology of increasing drilling rate by TorkBuster assisted with conventional geosteering power drill. Firstly, analysis was conducted to see if the new assembly had enough strength for drilling, thus preventing fatigue and damage of the drillstring caused by stress concentration; secondly, the TorkBuster pump pressure-displacement back-push equationwasusedtooptimizethedrillingparameters;ifnally,thepassingcapacityof?215.9mmand ?152.4 mm assembly was ana-lyzed as per the principle that the allowable bending radius must be less than the actual bending radius of slim hole/casing, hence realiz-ing safe running of the assembly and generating this technology for increasing drilling rate in slim hole horizontal well by TorkBuster in Qingshen Gasifeld, which was successfully used in Well Songshen 9H, providing a new technical approach for accelerating the explora-tion and development of deep sandy conglomerate gas pools.
