Bedrock hybrid drilling

A method of utilizing a millimeter wave drilling apparatus (300) is provided. The method may include monitoring penetrability of a first portion of a borehole of a well while forming the borehole using a drilling apparatus including a drill bit for mechanically removing material from within the borehole. The method may also include determining to utilize a millimeter wave drilling device based at least on the penetrability of the borehole falling below a penetrability threshold, the millimeter wave drilling device including a waveguide (430) configured to be inserted into the borehole. The method may further include forming a second portion of the borehole with the millimeter wave drilling apparatus in response to the determination. A method for controlling downhole pressure of a well is also provided. Related systems for performing the methods are also provided. 提供了一种利用毫米波钻井设备(300)的方法。所述方法可包含在使用钻井设备形成钻孔的同时监测井的所述钻孔的第一部分的穿透性，所述钻井设备包含用于从所述钻孔内机械去除材料的钻头。所述方法还可包含至少基于所述钻孔的所述穿透性下降到低于穿透性阈值而确定利用毫米波钻井设备，所述毫米波钻井设备包含被配置成
