    • The apparatuses and methods herein relate to techniques for extracting fluid from a subsurface formation. A downhole sampling tool is provided with a probe having an internal wall capable of selectively diverting virgin fluids into virgin flow channels for sampling, while diverting contaminated fluids into contaminated flow channels to be discarded. The characteristics of the fluid passing through the channels of the probe may be measured. The data generated during sampling may be sent to a controller capable of generating data, communicating and/or sending command signals. The flow of fluid into the downhole tool may be selectively adjusted to optimize the flow of fluid into the channels by adjusting the internal wall within the probe and/or by adjusting the flow rates through the channels. The configuraton of the internal wall and/or the flow rates may be automatically adjusted by the controller and/or manually manipulated to further optimize the fluid flow.
    • 这里的装置和方法涉及从地下地层中提取流体的技术。 井下采样工具设置有探头,该探头具有能够将原始流体选择性地转移到原始流动通道中的内壁,用于取样,同时将污染的流体转移到待丢弃的污染的流动通道中。 可以测量通过探针通道的流体的特性。 采样期间产生的数据可以发送到能够生成数据,通信和/或发送命令信号的控制器。 可以选择性地调节进入井下工具的流体流动,以通过调节探针内的内壁和/或通过调节通过通道的流速来优化流入通道的流体流。 内壁和/或流速的配置可以由控制器自动调节和/或手动操作以进一步优化流体流动。
