摘要： Methods, apparatus and products for separating oil and mud filtrate down hole and production of each to the surface via separate tubing, that includes custom engineered drill pipe for which two types of openings called ports have been cut or drilled: production ports and isolation ports. The production port produces formation fluid (normally hydrocarbons) from a perforation. In one non-limiting embodiment, a tube is welded to the inside of the casing at each production port to transmit the formation fluid to the top of the drill pipe section where it is attached to a custom engineered casing collar (described below) designed to allow flow to the next drill pipe section of the device. The isolation port produces mud filtrate from the adjacent borehole wall exterior to the casing, and these isolation ports are arranged in a pattern around each production port to keep mud filtrate in the invaded zone from reaching the production port. The number and placement of the production ports as well as the number, placement and shape of the isolation ports are determined using the information regarding the perforating design and other information such as the filtrate type and estimates of invasion depth as determined by well logs. Packers are set above and below the apparatus to provide an “isolation” chamber to contain the produced filtrate. Tubing through the upper packer will produce the filtrate to the surface via differential pressure or pumping. After the casing has been cemented, the perforating guns in the production ports are fired to begin production of formation fluid.

摘要： A method for calculating the orientation of a geologic feature with respect to the axis of a wellbore drilled through earth formations. The method uses finely detailed measurements of a selected property of the earth formations made along the wall of the wellbore. The method includes the steps of segregating the finely detailed measurements by an angle subtended with respect to an arbitrary reference on the circumference of the wellbore. The measurements are further segregated into a selected axial interval along the wellbore. For each segment, for each subtended angle, the segregated measurements are spectrally analyzed with respect to spatial frequency. Coefficients of a best fit curve are determined for the phase components of the spectrally analyzed measurements with respect to the subtended angle. The orientation of the geologic feature is calculated from the best fit curve. In the preferred embodiment a noise floor is calculated in each segment by stacking the amplitude components at each spatial frequency in each interval. For each spatial frequency, the stacked amplitude is compared to the noise floor. Only spatial frequencies having amplitudes above the noise floor are used to generate the best fit curve from their respective phase components.

摘要翻译： 一种用于计算地质特征相对于通过地层钻井钻井的轴线的取向的方法。 该方法使用精细详细测量沿井身壁形成的地层的选定性质。 该方法包括以下步骤：将精细细节的测量值相对于井筒圆周上的任意参考对准的角度分离。 测量进一步沿着井眼分离成选定的轴向间隔。 对于每个段，对于每个对角，相对于空间频率对分离的测量进行频谱分析。 针对光谱分析的测量值相对于对角度的相位分量确定最佳拟合曲线的系数。 从最佳拟合曲线计算地质特征的方向。 在优选实施例中，通过在每个间隔中堆叠每个空间频率处的振幅分量，在每个段中计算噪声底限。 对于每个空间频率，将堆叠幅度与本底噪声进行比较。 仅使用具有高于本底噪声的幅度的空间频率从其各自的相位分量产生最佳拟合曲线。

摘要翻译： 用于分离油和泥浆滤液井下的方法，设备和产品，以及通过单独的管道生产每个到表面的方法，设备和产品，其包括已经切割或钻出了称为端口的两种类型的开口的定制设计的钻杆：生产端口和隔离端口。 生产端口从穿孔产生地层流体（通常为碳氢化合物）。 在一个非限制性实施例中，管在每个生产端口处焊接到壳体的内部，以将地层流体传递到钻杆部分的顶部，在该顶部附接到设计为 允许流到设备的下一个钻杆部分。 隔离口从壳体外部的相邻钻孔壁产生泥浆滤液，并且这些隔离口以围绕每个生产端口的图案布置，以将泥浆滤液保持在入侵区域中，从而不会到达生产口。 使用关于穿孔设计的信息和诸如由测井确定的滤液类型和侵入深度的估计等信息来确定生产端口的数量和布置以及隔离端口的数量，布置和形状。 封隔器设置在设备的上方和下方，以提供“隔离”室以容纳生成的滤液。 通过上封隔器的管道将通过差压或泵送将滤液输送到表面。 套管固井后，生产港口的射孔枪开始生产地层流体。
