    • A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole is disclosed. In one step, a bottomhole assembly is inserted into the borehole. The formation is drilled with the bottomhole assembly. The formation may be characterized with logging tools, probes, sensors, seismic system and/or the like to create first information. One or more fractures are placed in the formation without removal of the bottomhole assembly from the wellbore. Further, continuous drilling of the formation is performed with the bottomhole assembly after/during placing the fractures. Further characterizing of the formation with the probes, sensors/systems or the like is performed to produce second information. Another fracture is placed with feedback from the second information. Repeating the drilling, characterizing and placing of fractures as necessary during the formation preparing process.
    • 公开了一种通过钻孔制备围绕井筒以承载烃的地层的方法。 在一个步骤中,将井底组件插入钻孔中。 井底组件钻出地层。 地层可以用测井工具,探测器,传感器,地震系统等来表征,以产生第一信息。 将一个或多个裂缝放置在地层中,而不从井筒移除井底组件。 此外,在放置裂缝之后/期间,利用井底组件进行地层的连续钻孔。 执行用探针,传感器/系统等进一步表征形成以产生第二信息。 第二个信息的反馈放置另一个裂缝。 在成型准备过程中,根据需要重复钻孔,表征和放置骨折。

    • Tubewaves are used to transmit an indication of the depth at which a condition is detected in a well. In particular, the depth is calculated based on the difference in arrival time at the surface of a first tubewave which propagates directly upward in the borehole and a second tubewave which initially travels downward and is then reflected upward. The tubewaves may be generated by a canister designed to implode at a certain pressure. The canister is carried downhole by gravity and the fluid being pumped. At a depth at which its pressure tolerance is exceeded, it implodes and generates the tubewaves. An analyzer at the surface detects the tubewaves and generates a pressure versus depth profile of the well. Canisters may be acoustically tagged in order to generate tubewaves having particular frequency and amplitude characteristics. Canisters may also be configured to produce multiple implosions.
    • 涡卷用于传输在井中检测到条件的深度的指示。 特别地,深度是基于在井眼中直接向上传播的第一管风管的表面到达时间的差异以及最初向下行进并然后被向上反射的第二管道涡流来计算的。 管道可以由设计成在一定压力下膨胀的罐产生。 罐通过重力运送在井下,并且被泵送的流体。 在超过其压力公差的深度处,它渗透并产生管道。 表面上的分析仪检测管道,并产生井的压力与深度分布。 罐可以被声学标记,以便产生具有特定频率和幅度特性的波管。 罐也可能被配置为产生多个内爆。
