Evaluation of the BKS LWD Tool Spatial Resolution Based on the Numerical Simulation Results

Abstract

Reservoir microimaging tools are currently one of the most high-tech devices used in wireline logging and logging-while-drilling. Based on a three-dimensional numerical simulation, the spatial resolution of the first Russian lateral scanning logging-while drilling tool was estimated. An algorithm for constructing a geoelectric model with an arbitrary distribution of electrical resistivity in the near-wellbore space is described.

Impact of High‐Tech Image Formats Based on Full‐Frame Sensors on Visual Experience and Film‐Television Production

“…In order to adapt to the function of ODVS that can simultaneously shoot 360-degree panoramic images of the scene, the mobile surface laser generator must project a laser light source that can cover 360 degrees in the horizontal direction of the scene. It can move up and down in the vertical direction to complete the scan of the scene [20]. Based on this design goal, the following article will first introduce the principle of laser ranging and then explain the specific design of the moving surface laser generator in ASODVS and the assembly method of the moving surface laser light source [21].…”

“…Commonly used laser ranging principles are triangle ranging method, time-of-flight method, and phase method [20]. The triangulation method is a method of measuring the distance between the target point and the known end point of a fixed reference line, as shown in Figure 3.…”
