Video Log Visual Detection Technology of Horizontal Well and Its Application

Horizontal wells increase the contact surface area between wells and reservoirs, so they can enhance oil recovery efficiency effectively. In order to obtain more logging information of horizontal wells, this paper studies the visualization detection technology of horizontal well. By using two-way coding and local large capacity high-speed storage equipment to realize three operation mode-three operation modes of surface readout mode, memory mode and compatibility mode. Special connectors are used to make VideoLog tool to work in three methods by parallel transmission. Video acquisition and analysis software realizes 3D modeling and quantitative analysis of casing pipe. Field tests of 8 horizontal wells show that VideoLog can provide a new horizontal well detection scheme.
