    • Conventional organophilic clays, when used as rheological additives in oil based invert muds, display marked viscosity loses in the mud when these muds are heated much above 350° F., whereas muds prepared according to the present invention are dramatically more viscosity stable at temperatures through 500° F. The present invention relates to the discovery of oil based invert emulsion drilling fluids that provides more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional fluids containing organoclays. As a result, the inventive fluids of this invention are ideal candidates for high temperature applications. This invention in another aspect of this invention is a process for improving the rheological properties of oil well drilling fluids particularly useful for oil-based invert emulsion types of drilling fluids. The new process uses as a rheological viscosifer for such fluids as a specific organoclay which when added to a drilling fluid at from about 0.5 and 5% by weight creates an inventive drilling fluid composition less sensitive to the very hot temperatures found in the drilling hole, and in the long stem of drilling pipe.
    • 常规的亲有机粘土当用作油基反向泥浆中的流变添加剂时,当这些泥浆被加热到高于350°F时,在泥浆中显示出显着的粘度损失,而根据本发明制备的泥浆在通过 500°F。本发明涉及油基反相乳液钻井液的发现,当与含有机粘土的常规流体相比时,其能够在变化的温度下提供更稳定的钻井液粘度和抗沉降性能。 因此,本发明的发明流体是高温应用的理想候选物。 本发明在本发明的另一方面是一种改进油井钻井液流变性能的方法,特别适用于油基反相乳液型钻井液。 新方法用作这种流体的流变粘稠剂,例如特定的有机粘土,当以约0.5和5重量%的量加入到钻井液中时,会产生对钻孔中发现的非常高的温度敏感的本发明的钻井液组合物, 并在钻杆的长杆上。

    • A system for generating parametric stereo data from phase modulated stereo data is provided. A phase difference system receives left channel data and right channel data and determines a phase difference between the left channel data and the right channel data. A phase difference weighting system receives the phase difference data and generates weighting data to adjust left channel amplitude data and right channel amplitude data based on the phase difference data. A magnitude modification system adjusts the left channel amplitude data and the right channel amplitude data using the weighting data to eliminate phase data in the left channel data and the right channel data.
    • 提供了一种从相位调制立体数据产生参数立体声数据的系统。 相位差系统接收左声道数据和右声道数据,并确定左声道数据和右声道数据之间的相位差。 相位差加权系统接收相位差数据,并产生加权数据,以根据相位差数据调整左声道幅度数据和右声道幅度数据。 幅度修正系统使用加权数据来调整左声道幅度数据和右声道幅度数据,以消除左声道数据和右声道数据中的相位数据。
