Weatherford安全钻井系统使原来不能钻的井变得可钻,适用于孔隙压力和地层压裂梯度差值较小的井。该安全钻井系统使用微流控制技术,通过采用一种专有的计算方法,来实时发现和测量井下微小的流量进出。回流用带节流阀的管线上安装的高精度流量计进行测量,能非常及时地自动探测到
The Weatherford safety drilling system makes drillable wells drillable for wells with small differences in pore pressure and formation fracturing gradients. The safe drilling system uses microfluidic control technology to detect and measure downhole minute flows in and out by using a proprietary method of calculation. The return flow is measured with a high-precision flow meter mounted on a line with a throttle valve and can be automatically detected very timely
