摘要： Systems, methods, and devices for determining neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, neutron detector, two gamma-ray detectors, and data processing circuitry. Neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. Neutron detector may detect a count of neutrons representing the extent of the neutron cloud. Gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.
摘要翻译：提供了用于确定在液体和气体填充地层中准确的地下地层的中子 - 伽马密度（NGD）测量的系统，方法和装置。例如，用于获得这样的NGD测量的井下工具可以包括中子发生器，中子探测器，两个γ射线检测器和数据处理电路。中子发生器可以将中子发射到地层中，形成快中子云。中子检测器可以检测代表中子云范围的中子数。伽马射线探测器可以检测由不规则地离开地层的中子引起的非弹性γ射线的计数。由于快中子云的程度可以根据地层是液态的还是气体填充而变化，数据处理电路可以至少部分地基于归一化到计数的非弹性γ射线的计数来确定地层的密度的中子。

摘要： Downhole drilling fluid measurements are made as a function of time or as a function of depth. A change in the downhole drilling fluid measurements is correlated to a feature of a formation penetrated by a drill bit or to a feature of fluids in the formation. The downhole drilling fluid measurements may include density, photoelectric factor, hydrogen index, salinity, thermal neutron capture cross section (Sigma), resistivity, slowness, slowing down time, sound velocity, and elemental composition. The feature may include fluid balance, hole-cleaning, a kick, a shallow water flow, a formation fluid property, formation fluid typing, geosteering, geostopping, or an environmental correction. A downhole system has a measurement-while-drilling tool or a logging-while-drilling tool and a processor capable of obtaining the downhole drilling fluid measurements and correlating the change in the downhole drilling fluid measurements.

摘要： An apparatus for measuring characteristics of earth formations surrounding a borehole, comprises a resistivity measurement device having a multiplicity of antennae spaced between each other in a longitudinal direction of the apparatus. A neutron measurement device of the apparatus comprises at least a neutron source and at least a neutron detector, each of the neutron detectors being at a distance from the neutron source in the longitudinal direction of the apparatus. The multiplicity of antennae are interleaved with the neutron measurement device in order to reduce a total length of the apparatus and in order to allow a determined area of the earth formation to be measured simultaneously using the neutron measurement device and the resistivity measurement device.
