METHOD AND APPARATUS FOR INCREASING THE EFFICIENCY OF A FLUORESCENCE MEASUREMENT CELL |
摘要 |
An apparatus for estimating a property of a fluid in an earth formation, the apparatus including: a logging instrument configured to be conveyed in a borehole penetrating the formation; and a plurality of light sources disposed at the logging instrument; wherein each of the light sources is configured to illuminate a sample of the fluid with a light beam causing the sample to fluoresce light with a characteristic related to the property, each of the light sources being configured to provide a light beam with a solid angle and a distance traveled to the sample, the solid angle and the distance being configured to concentrate the beam at an area of the sample that is overlapped substantially a same amount by a beam from another light source in the plurality. |
