摘　　要：随着油田开发力度的加大,大斜度及水平井部署比例越来越大,同时碳酸盐岩储层易喷易漏,电缆及传输测井井控风险大,时效性慢,成功率低,为此引进了过钻杆存储式测井仪器。文章分析了该仪器在碳酸盐岩地层中的作业情况,通过对比电缆、随钻、传输测井资料,结合交会图分析技术,对该仪器测井资料的测井质量和评价方法进行了研究。分析表明该测井仪器资料适用于碳酸盐岩复杂地层,自然伽马、电阻率及声波、放射性测井资料质量较好,能够满足储层评价需要。经过测井资料储层评价后,优选了测试层段,多口井的试油结果验证了测井资料的准确性。Highly-deviated wells and horizontal wells are deployed more and more with oilfield development. Wireline logging and cable communication logging have disadvantages of high risk, slow time efficiency and low success rate because carbonate formation blows out and losses easily. So LWF is introduced. The paper analyzes the performence of the logging device in carbonate formation. The quality of logging data and evaluation method were studied though comparing with wireline, LWD, cable communication logging and combining with crossplot technique. Analysis demonstrates that this machine can do well in carbonate comprehensive formation and gamma ray、resistivity、acoustic wave and radioactivity logs are so good that it can satisfy the evaluation of carbonate reservoirs. The result of test zone optimized based on the evaluation verifies reliability of the logging data.
