摘要： An x-ray tool for determining a characteristic of an oilfield fluid. The tool may include a generator portion housing a collimator about a target from which x-rays are emitted. In this manner x-rays may be attenuated right at the target such that a majority of shielding otherwise necessary for safety concerns may be eliminated. Rather, by employing the target within the collimator, shielding of the generator may be limited to a single shielding plate within the generator portion that is positioned parallel to the target at the opposite end of an x-ray tube therebetween. As a result of this configuration, an x-ray tool for analysis of oilfield fluids may be provided that is no more than about 50 lbs. in total weight. Thus, hand-held user friendly embodiments may be safely employed at the oilfield.

摘要： Disclosed is a radiation logging tool, comprising a tool housing; a compact generator that produces radiation; a power supply coupled to the compact generator; and control circuitry. Embodiments of the compact generator comprise a generator vacuum tube comprising a source generating charged particles, and a target onto which the charged particles are directed; and a high voltage supply comprising a high voltage multiplier ladder located laterally adjacent to the generator vacuum tube. The high voltage supply applies a high voltage between the source and the target to accelerate the charged particles to a predetermined energy level. The compact generator also includes an electrical coupling between an output of the high voltage supply and the target of the generator vacuum tube to accommodate the collocated positions of the generator vacuum tube and the high voltage power supply.

摘要： A scintillator type radiation detector package is provided including a scintillation crystal directly coupled to the window of a photomultiplier. A scintillator package is also provided having a longer life at wellbore temperature with minimal deterioration of a hygroscopic scintillation crystal(s). Direct optical coupling of the scintillator to the photomultiplier reduces the amount of light lost at coupling interfaces and improved detection resolution over the conventional structures having separate packages for crystal and photomultiplier.

摘要： Systems and methods for neutron porosity well logging with high precision and reduced lithology effects are provided. In accordance with an embodiment, a downhole neutron porosity tool may include a neutron source, a neutron monitor, a neutron detector, and data processing circuitry. The neutron source may emit neutrons into a subterranean formation while the neutron monitor detects a count of neutrons proportional to the neutrons emitted. The neutron detector may detect a count of neutrons that scatters off the subterranean formation. The data processing circuitry may determine an environmentally corrected porosity of the subterranean formation based at least in part on the count rate of neutrons scattered off the subterranean formation normalized to the count rate of neutrons proportional to the neutrons emitted by the neutron source.

摘要： An apparatus for determining fractional amounts of each phase of a multiple phase fluid includes an x-ray generator includes a sample chamber is configured to admit therein a sample of fluid for analysis. The chamber is disposed in a radiation path output from the generator. A filter is disposed in the radiation path between the output of the generator and the radiation input of the sample chamber. A first radiation detector is positioned in a radiation path from the sample chamber after radiation has passed through the sample chamber. A thickness and a material of the filter are selected to optimize resolution of radiation detected by the first detector to changes in volume fraction of oil and water in the fluid sample when a gas fraction thereof is between about 90 to 100 percent.

摘要： An apparatus and method for determining the density and other properties of a formation surrounding a borehole using a high voltage x-ray generator. One embodiment comprises a stable compact x-ray generator capable of providing radiation with energy of 250 keV and higher while operating at temperatures equal to or greater than 125° C. In another embodiment, radiation is passed from an x-ray generator into the formation; reflected radiation is detected by a short spaced radiation detector and a long spaced radiation detector. The output of these detectors is then used to determine the density of the formation. In one embodiment, a reference radiation detector monitors a filtered radiation signal. The output of this detector is used to control at least one of the acceleration voltage and beam current of the x-ray generator.
