摘要： Methods and apparatus for the characterization of formation fluids are disclosed. A downhole tool disposed in a borehole penetrating a subterranean formation obtains a NMR measurement, effects a change in a characteristic of the formation fluid, and obtains another NMR measurement subsequent to the change. Alternatively, the downhole tool effects a radial gradient of a characteristic of the formation and obtains NMR measurements at two or more selected radial distances from the wellbore wall. A parameter representative of the subterranean formation or the formation fluid is further determined from the NMR measurements.

摘要： The present invention provides methods for determining the bound fluid volume (BFV) of a formation utilizing nuclear magnetic resonance (NMR) techniques in which less than full polarization occurs and in which less than a complete NMR distribution is acquired. The effect of the polarizing static magnetic field is shortened in time by applying a shortened wait time between NMR measurements so that only the bound fluid of the formation is polarized. The shortened wait time is effectuated by early application of the oscillating magnetic field to the formation which, in conjunction with a limited number of refocusing pulses, induces signals in the formation that are measured by the NMR tool. The peak amplitude of these signals corresponds to the BFV. The present invention provides information so that a partial polarization calculation curve in T2 lies almost equally between an empirical tapered cutoff curve and a theoretical tapered cutoff curve. Moreover, because no T2 information must be acquired, the method is especially suited for logging-while-drilling operations, where the drill string moves uncontrollably during the NMR measurement.
摘要翻译：本发明提供使用核磁共振（NMR）技术测定地层的结合流体体积（BFV）的方法，其中发生少于全极化，并且其中获得小于完整的NMR分布。通过在NMR测量之间施加缩短的等待时间来缩短偏振静磁场的效果，使得只有结合的结构的流体被极化。缩短的等待时间是通过将振荡磁场早期应用于地层来实现的，其结合有限数量的重聚焦脉冲，通过NMR工具测量地层中的信号。这些信号的峰值幅度对应于BFV。本发明提供信息，使得T2中的部分极化计算曲线几乎等同于经验锥形截止曲线和理论锥形截止曲线之间。此外，由于不能获得T2信息，所以该方法特别适用于在钻井操作期间的钻井操作，其中钻柱在NMR测量期间不受控制地移动。

摘要： A method and apparatus for determining gas corrected porosity using nuclear magnetic resonance (NMR) and density measurements is disclosed. The total porosity (TCMR) or an earth formation is determined using an NMR tool. A log output is generated that indicates the density of the formation. The density porosity of the formation is determined from the log output. The difference between the TCMR-density porosity log accurately indicates the presence of gas. A gas corrected porosity, .phi., and gas saturation, S.sub.g, are determined based upon the density porosity and TCMR.
