摘要：马深1井是中石化部署幕在川东北通南巴构造带马路背构造高部位上的一口重点预探并，完钻井深8418m，二开 0444.5mm/0406.4mm大并眼钻达4295m，为该地区最深大井眼段。该井段以陆相地层为主，地质条件复杂，地层可钻性差，并壁不稳定以及地层软硬交错且倾角较大，且在水力参数和破岩能量等方面存在一系列问题。针对不同地层特征和岩石性质优选了气体钻井、大担矩螺杆+PDC、涡轮+孕镶、混合钻头、旋冲工具等多项新技术、新工具，基于动力学防斜打快理论，在保证并身质量的前提下大幅提高了机械钻速。同时，自主研制了KCI聚胺防竭钻并液体系，有效解决了井壁失稳的问题，

Abstract: Well Mashen-1 is a keyvertical exploration well which located at high part of Malubei structure of Tongnanba structure belt and was deployed by SINOPEC. The main part of this well is continental formation.This area is with complex geological conditions, poor drillability, the problem of bore-hole stability, formation alternating hard and soff,and dip angle is bigger. And in the hydraulic pa-rameters and break-rock energy, as well as a series of problems. Through in-depth study and analysis. According to different strata char-acteristics and rock properties, the application of gas drilling, high torque screw + PDC, turbine + impregnated diamond bit, hybrid bit and rotary percussion tool such as new drilling technology and new tools are optimized. Based on the theory of dynamic anti oblique and fast drilling.Ensure wellbore quality and effectively improve mechanical drilling speed. At the same time, adopted the self-developed KCl polyamine an-ti-cavingcapacities drilling fluid system. This technique successfully cope with the wellbore instability
Key words: Well Mashen-1; big hole; quick and optimal drilling; stable borehole
随着大尺寸井段的加深，机械钻速慢的问题越来越突出，严重地影响到全井的钻井周期和钻井成本【1]。马深1井主探下寒武统龙王庙组和上震旦统灯影组，完钻井深8418m，刷新了亚洲陆上第一超深井钻井记录。该井位于川东北通南巴构造带马路背构造，二开封隔嘉二段产层以上易漏地层，为下开次揭开嘉陵江组、飞仙关组高压气层创造条件。采
用了0444.5mm/0406.4mm钻头钻进至嘉二段地层，中完井深4295m，为当前川东北地区最深的大尺寸井段。
该并段以陆相地层为主，钻遇侏罗系沙溪庙组、千佛崖组和自流井组，三叠系须家河组、雷口坡组以及嘉陵江组上部。地质条件复杂，井眼尺寸大、进尺深，给大井眼优快钻井带来诸多难题，成为全并
