    • Features of subsurface earth reservoirs of interest are made available for analysis and evaluation by forming three-dimensional, geologic block models based on field data. The field data include geological observations, such as lithofacies and porosity values obtained from well data and other sources, as well as geophysical data, usually from seismic surveys. The geologic models representative of subsurface reservoirs so obtained are optimized to match as closely as feasible geologic constraints known or derived from observed geologic data. The models also conform to geophysically based constraints indicated by seismic survey data. The modeled geologic lithofacies and porosity are converted into acoustic velocity and bulk density values, which are then formulated as a seismic response which is then compared with actual seismic data. A perturbation process on lithofacies and porosity can be iteratively repeated until a representation of the reservoir is obtained which is within specified limits of accuracy or acceptability.
    • 通过形成基于现场数据的三维地质块模型,可以对感兴趣的地下储层进行分析和评估。 现场数据包括地质观测资料,例如从井数据和其他来源获得的岩相和孔隙度值,以及通常来自地震勘测的地球物理数据。 如此获得的地下储层的代表性地质模型进行了优化,以便与已知或从观测地质资料得出的可行的地质约束尽可能接近。 这些模型也符合地震勘测数据所指示的地球物理学基础。 模拟地质岩相和孔隙度被转换为声速和体积密度值,然后将其制定为地震响应,然后与实际地震数据进行比较。 可以迭代地重复对岩相和孔隙度的扰动过程,直到获得在准确度或可接受性范围内的储层的表示。

    • A protection device and circuit for a fluid pump or the like including a motor control relay MS for actuating relay contacts MS-1, MS-2, MS-3 that control the communication of power to a drive motor 10a, and a manual reset motor protection device 24 that deenergizes the control relay in response to sensed malfunctions. The motor protection device comprises a manual reset motor protector 40 having switch contacts 42 connected in series with the motor control relay and a tripping coil 44 which, when energized, opens the switch contacts. A current shunt path 46 including serially connected pump assembly mounted sensors 48, 50, normally shunts current around the tripping coil and is interrupted in the event of a sensed malfunction, causing the energization of the tripping coil which opens the switch contacts and deenergizes the drive motor. The switch contacts must be manually reclosed to reactivate the pump assembly. The impedance of the tripping coil and the motor control relay are selected so that should the switch contacts fail to open in response to energization of the tripping coil, the impedance of the tripping coil will reduce the voltage on the control relay below its seal-in value, thereby deenergizing the control relay.
    • 一种用于流体泵等的保护装置和电路,包括用于驱动控制与驱动电动机10a的电力通信的继电器触点MS-1,MS-2,MS-3的电动机控制继电器MS以及手动复位电动机 保护装置24,其响应于感测到的故障而使控制继电器断电。 电动机保护装置包括具有与电动机控制继电器串联连接的开关触头42的手动复位电动机保护器40以及当被激励时打开开关触点的跳闸线圈44。 包括串联连接的泵组件安装的传感器48,50的电流分流路径46通常在脱扣线圈周围分流电流,并且在感测到的故障的情况下中断,导致断开线圈的通电,该跳闸线圈打开开关触点并使驱动器通电 发动机。 开关触点必须手动重新闭合以重新启动泵组件。 选择跳闸线圈和电动机控制继电器的阻抗,使得响应于跳闸线圈的通电,开关触点不能断开时,跳闸线圈的阻抗将使控制继电器上的电压降低到其密封 值,从而使控制继电器断电。
