偶极横波远探测测井识别碳酸盐岩地层异常体可靠性研究

为了研究偶极横波远探测测井识别碳酸盐岩地层异常体的可靠性，在碳酸盐岩地层中设计钻探了直井、水平井2种试验井，进行了偶极横波远探测测井。测井解释结果表明，偶极横波远探测测井在碳酸盐岩直井中能准确识别出异常体及其方位，在碳酸盐岩水平井中识别出的异常体位置基本可靠。塔河油田1口井和顺北油气田1口井采用了偶极横波远探测测井技术，2口井测井识别出的异常体位置与通过酸压曲线判断的异常体的位置相对应。研究结果表明，偶极横波远探测测井能准确识别出碳酸盐岩地层中的异常体，可为碳酸盐岩储层评价和碳酸盐岩油气藏的开发提供支持。 

Reliability Study of Anomalies Identified Through Logging by Dipole Shear-Wave Remote Detection in Carbonate Formations

Vertical and horizontal wells were designed and drilled in carbonate formations for the logging by dipole shear-wave remote detection to study the reliability of identified anomalies in logging data obtained by this way. The interpretation results of the logging data revealed that logging by dipole shear-wave remote detection could accurately identify the anomalies and their orientations in the vertical wells in carbonate formations, and their locations identified in horizontal wells were reliable. The logging by dipole shear-wave remote detection for logging were conducted in two wells of Tahe Oilfield and Shunbei Oil & Gas Field, and the locations of anomalies identified through logging were consistent with those from the acid-fracturing treatment curves. The research results indicate that logging by dipole shear-wave remote detection can accurately identify anomalies in carbonate formations, which can provide support for the evaluation and development of carbonate reservoirs.
