摘要： A fast, efficient and accurate pseudo 2-D inversion scheme for resistivity determination of an anisotropic formation uses data from a tool (3DEX) comprising three transmitters and three corresponding receivers sampling the formation in a plurality of spatial directions. An initial model of the formation including invasion zones is obtained using a conventional multifrequency and/or multispacing logging tool. A pseudo 2-D inversion scheme combines an accurate full 2-D forward solution of the synthetic responses of the earth model with a 1-D approximation of the sensitivity matrix of the horizontally layered anisotropic background model. The timesaving compared to a regular 2-D inversion scheme can be tremendous. The applicability of this scheme is important in cases when borehole and near-zone effects do not allow an interpretation based on 1-D inversion. A comparison of the pseudo 2-D inversion scheme versus a full 2-D inversion using a realistic synthetic example shows that the pseudo 2-D inversion scheme performs as well as the full 2-D inversion, but in a much shorter time.

摘要： Data are acquired using multi-array logging tool in a borehole having an angle of inclination to a normal to the bedding plane of earth formations. The multi-array measurements are filtered using angle dependent filters to give a filtered curve corresponding to a target one of the multi-array measurements using angle dependent filters. Correlation coefficients are determined for a set of possible dip angles and a relative dip angle is estimated from the correlation coefficients. This dip angle estimate together with bed boundaries obtained from the multi-array measurements are used for inverting multi-component measurements alone or jointly with multi-array measurements to refine the relative dip angle interpretation and give horizontal and vertical formation resistivity.

摘要： A method is discussed for obtaining resistivity values in a horizontal or highly-deviated wellbore penetrating an anisotropic formation layer. Multi-component data is obtained from the formation layer. An initial value of horizontal and vertical resistivity can be determined by using a whole space model and assuming an isotropic layer. Revised values of the vertical and horizontal resistivities are obtained through a first and second inversion process. A first inversion is performed on the horizontal resistivity, holding a value of vertical resistivity constant. A second inversion is performed on the vertical resistivity, holding a value of horizontal resistivity constant. These inversions are iterated until a desired convergence is achieved.

摘要： Measurements made by a multicomponent logging tool in a borehole are inverted to obtain horizontal and vertical resistivities of a formation traversed by the borehole. The model includes layers of equal thickness, each layer having a horizontal resistivity and a vertical resistivity. For a vertical borehole, the inversion is done by first iteratively obtaining the horizontal resistivities of the layer using the Hzz component of the data wherein in successive steps of the iteration, the horizontal resistivity for each layer is multiplied by a ratio of a model Hzz output to the measured Hzz. The vertical resistivity model is set equal to the derived horizontal resistivities and the iterative process is repeated using the ratio of the model Hxx output to the measured Hxx. A similar process is used for boreholes with a known inclination. For such an inclined borehole, the two horizontal components Hxx and Hyy are summed to give a horizontal measurement Hxxyy that is independent of tool rotation. The first step uses a ratio of the model Hzz output to the measured Hzz data to obtain an apparent resistivity, and, in the second step, the ratio of the model Hxxyy output and the measured Hxyy data are used along with a known relationship between the apparent resistivity and the horizontal and vertical resistivities in an iterative manner. No Jacobians or gradients are necessary in the method, so that computational times are small relative to prior art gradient methods.
摘要翻译：通过钻孔中的多组分测井工具进行的测量被反转，以获得由井眼穿过的地层的水平和垂直电阻率。该模型包括相同厚度的层，每层具有水平电阻率和垂直电阻率。对于垂直钻孔，通过首先使用数据的Hzz分量迭代地获得层的水平电阻率来进行反演，其中在迭代的连续步骤中，每层的水平电阻乘以模型Hzz输出的比率到测量的Hzz。将垂直电阻率模型设置为等于导出的水平电阻率，并使用Hxx输出模型与测量的Hxx的比值重复迭代过程。类似的工艺用于具有已知倾角的钻孔。对于这样的倾斜钻孔，两个水平分量Hxx和Hyy相加得到一个与工具旋转无关的水平测量Hxxyy。第一步使用Hzz型输出与测量的Hzz数据的比率来获得视电阻率，并且在第二步中，使用模型Hxxyy输出和测量的Hxyy数据的比率以及已知的关系视电阻率和水平和垂直电阻率的迭代方式。在该方法中不需要Jacobian或梯度，因此相对于现有技术的梯度方法，计算时间较小。

摘要： An apparatus for performing a nuclear magnetic resonance (NMR) measurement in a borehole penetrating a subsurface formation includes an NMR tool having an outside diameter that is less than an inside diameter of a drill tubular disposed in the borehole, the drill tubular having an opening at the distal end of the drill tubular leading into the borehole, and a retaining device configured to allow at least a section of the NMR tool to protrude through the opening of the drill tubular and prevent an unrestrained release of the NMR tool through the opening. The apparatus also includes a transmitter antenna and a receiver antenna coupled to the NMR tool, wherein the transmitter antenna and/or the receiver antenna are extendable from the NMR tool.
