    • Disclosed is a device and method and/or system for generating pulses to improve drilling rates, the ability to drill straighter and farther or fracturing or injection efficiencies in a geological formation that may contain desirable hydrocarbons. This system may also be used in other types of drilling or fracturing operations, whether to unclog arteries or to open formations for underground storage in conjunction with pulsing/fracturing. Alternately, this system could be used to create large pulses downhole for seismic purposes in that they are of such magnitude that they could be readily received in nearby wells or several of uphole locations. The system and method comprises several pulse generating devices longitudinally and axially positioned within an annular drill collar flow channel or PIM such that the PFD medium flows through the annular drill collar flow channel and the PFD medium is guided into one or more sets of selectively reversible flow, upper and lower flow connecting channels, wherein the connecting channels are connected to an inner flow channel and the annular drill collar flow channel, and wherein the annular drill collar flow channel is acted upon by one or more flow throttling devices. In one of the devices listed, the device utilizes one or more turbines residing near and within proximity of a flow diverter that diverts drilling mud into and away from turbine blades such that the force of the PFD medium causes the turbine blades and the turbine to rotationally spin around a coil assembly for power.
    • 公开了一种用于产生脉冲以提高钻井速率的装置和方法和/或系统,能够在可能包含所需烃的地质层中钻更直和更远或压裂或注入效率的能力。 该系统还可以用于其他类型的钻井或压裂作业,无论是停止动脉还是与脉冲/压裂一起打开用于地下储存的地层。 或者,该系统可以用于为了地震目的而在井下产生大的脉冲,因为它们具有如此大的程度,使得它们可以容易地接收在附近的井或几个井上位置。 系统和方法包括纵向和轴向地定位在环形钻铤流动通道或PIM内的多个脉冲发生装置,使得PFD介质流过环形钻铤流动通道,PFD介质被引导到一组或多组选择性可逆流 上部和下部流动连接通道,其中连接通道连接到内部流动通道和环形钻铤流动通道,并且其中环形钻铤流动通道由一个或多个流量调节装置作用。 在所列出的装置之一中,该装置利用一个或多个位于分流器附近和附近的涡轮机,其将钻井泥浆转入和离开涡轮机叶片,使得PFD介质的力导致涡轮叶片和涡轮旋转 旋转绕线圈组件供电。
