摘要： A method and system for monitoring the operation of downhole equipment, such as electrical submersible pumps, is disclosed. The method and system rely on the use of coiled fiber optic sensors, such as hydrophones, accelerometers, and/or flow meters. These sensors are either coupled to or placed in proximity to the equipment being monitored. As the sensor is perturbed by acoustic pressure disturbances emitted from the equipment, the length of the sensing coil changes, enabling the creation of a pressure versus time signal. This signal is converted into a frequency spectrum indicative of the acoustics emissions of the equipment, which can then be manually or automatedly monitored to see if the equipment is functioning normally or abnormally, and which allows the operator to take necessary corrective actions.

摘要： A method for detecting the presences of fractures in a subsurface formation being penetrated by a drill bit during drilling. Teeth on the drill bit act as individual seismic sources, generating both shear wave energy and compressional wave energy. As the drill bit passes through a formation, the shear wave energy generated by the bit propagates along the formation in a waveguide mode between the adjacent formations. As the shear wave signal passes through a fractured zone of the formation, two shear wave signals are generated, each polarized in relationship to the orientation of the fractures in the formation. As the polarized signals propagate along the formation, secondary shear wave signals are generated which return to the surface and are detected by appropriate sensors. The sensors have a plurality of detectors in order to detect the polarity or direction of particle motion cuased by the polarized wave, providing information that a fracture zone exists in the subsurface.

摘要： A method for predicting the formation pore-pressure ahead of the drill bit while drilling is disclosed. During the drilling process, the drill bit impacting the earth generates a seismic signal. The seismic signal propagate away from the drill bit in a radial fashion with some rays paths propagating directly towards the surface, while others propagating downward are reflected back towards the surface. The direct and reflected seismic signals are received by seismic sensors at one or more locations. The signals produced by the sensors are recorded for later processing. From the recorded signals an interval velocity for each formation behind the drill bit is determined much in the same way a vertical seismic profile is made. From the reflected seismic signals, an acoustic impedance for each formation ahead of the drill bit is determined. The results of the interval velocity determination and the acoustic impedance information are combined to produce a log-like impedance estimation curve which reflects the pore-pressure present in the subsurface units ahead of the drill bit. This information is helpful to the drilling engineer who can predict the appropriate weight of the drilling mud and thus prevent possible blow-outs and pressure kicks.
摘要翻译：公开了一种用于预测钻头在钻头前方的地层孔隙压力的方法。在钻井过程中，撞击地球的钻头产生地震信号。地震信号以径向方式传播离开钻头，其中一些射线路径直接传播到该表面，而另一些向下传播的射线路径朝向表面反射。直接和反射的地震信号由地震传感器在一个或多个位置接收。由传感器产生的信号被记录以供稍后处理。从记录的信号中，钻头后面的每个形成的间隔速度以与制造垂直地震剖面相同的方式被确定。从反射的地震信号中，确定钻头前面的每个地层的声阻抗。将间隔速度确定和声阻抗信息的结果组合起来产生一个对数似的阻抗估计曲线，该曲线反映钻头前面地下单元中存在的孔隙压力。这些信息有助于钻井工程师，他可以预测钻井泥浆的适当重量，从而防止可能的爆破和压力踢。
