ReelWell钻井反向射流抽吸技术及工具研究
|
摘要
ReelWell钻井技术以双壁钻杆为基础,钻井液从双壁钻杆环空进入钻头,携带岩屑的钻井液通过内钻杆返回地面,实现钻井液循环。在整个循环中,需要利用流动转换装置,此装置对岩屑能否顺利进入内钻杆产生巨大影响。鉴于此,根据射流泵理论提出一种利用高速反向射流抽吸岩屑的流动转换装置。建立了流动转换装置的水力模型,并对其进行优化设计。研究结果表明:摩擦因数越大,工具的水力效率越低,抽吸效果越差,建议水力流道在设计时应尽量光滑;密度比越大,工具的水力效率越低,抽吸效果越差,建议降低钻井液的密度比;该工具最优水力效率、最优压力比、最优流量比和最优面积比分别为16. 783%、0. 168 0、0. 974 1和0. 110 3。结论认为,反向射流抽吸技术的开发为提高ReelWell钻井携岩效率提供了一种新的方法。
ReelWell drilling technology is based on double-walled drill pipe. The drilling fluid flows into the drill bit from the double-walled drill pipe annulus,and then carries the cuttings and returns to the ground through the inner drill pipe to realize the drilling fluid circulation. Throughout the circulation,it is necessary to utilize a flow diverting device that has a large impact on the cutting to smoothly enter the inner drill pipe. In view of this,a flow diverting device for pumping cuttings using a high-speed reverse jet is proposed based on the jet pump theory.The hydraulic model of the device is established and optimized. The results show that the larger the friction factor,the worse the hydraulic efficiency and suction performance of the tool. The hydraulic flow channel should be as smooth as possible in design. Higher density ratio results in worse hydraulic efficiency and suction performance of the tool. The density ratio of the drilling fluid is proposed to be reduced. The optimal hydraulic efficiency,optimal pressure ratio,optimal flow ratio and optimal area ratio of the tool are 16. 783%,0. 168 0,0. 974 1 and 0. 110 3,respectively. The development of reverse jet suction technology provides a new method for improving the cutting carrying efficiency of ReelWell drilling.
