Well-Sun - Segmented Cement Bonding Tool for Precise Cement Bond Logging
The Segmented Cement Bonding Tool (SBT) is an advanced cement bond logging tool designed for precise measurement and evaluation of cement bond quality. The tool segments the casing, cement annulus, and formation into six areas for detailed analysis. It features sensors that are pressed against the well wall, ensuring high measurement accuracy, unaffected by external factors like casing fouling, micro annulus, formation speed, or changes in mud properties. The SBT generates a comprehensive cement image, depicting grooves and voids with precision. The tool also includes a Variable Density Log (VDL) at the bottom of the tool string that captures the full wave train, analyzing the bond between the formation and cement annulus. Incorporating a Casing Collar Locator (CCL) and Gamma Ray Tool (GRT), it provides accurate depth information for the acoustic signals. The SBT is specifically used to measure cement bond quality at both the first and second interfaces – between casing and cement annulus, and between cement annulus and formation. Additionally, it facilitates gamma ray measurements for precise depth correction.Most popular related searches
