摘要：

松辽盆地资源与环境深部钻探工程计划实施两井四孔，其中松科2井东孔是钻探的主体钻孔，设计井深为6 400 m，拟穿透白垩纪地层。松科2井东孔的实施对于开展白垩纪沉积环境和气候研究、实现油气勘探新突破、提升深部钻探技术和复杂井况的测井技术水平等具有重要意义。围绕钻探的科学目标和任务，结合松科2井东孔钻井工程设计及井况特点，开展了测井设计。提出松科2井东孔拟采用先进的测井仪器设备采集测井数据，设计的测井方法系列包括裸眼井综合测井和套管井固井质量检查测井2大类。根据钻井开次和钻进计划情况，设计了8次裸眼井综合测井和5次套管井固井质量检查测井。不同钻井开次的裸眼井综合测井项目有所不同；考虑到井深4 500 m以下高温测井的挑战性，设计了必测项目和选测项目。总之，松科2井东孔测井设计既力求取全取准各项测井资料，又体现了应对复杂井况的灵活性，有利于松辽盆地资源与环境深部钻探科学目标的顺利实现。

Abstract:

CCSDSK2 East Borehole is the main borehole of China Continental Scientific Drilling Project in Songliao Basin, which is designed to reach a depth of 6400 m to penetrate Cretaceous strata. Its implementation is important for the research of the Cretaceous sedimentary environment and climate, for the achievement of new breakthroughs in oil and gas exploration, for the enhancement of the deepdrilling level and geophysical logging techniques, etc. Based on the scientific objectives and tasks of this project, combined with the design of drilling engineering and the characteristics of well conditions, the authors carried out the logging design of CCSDSK2 EastBorehole，intending to adopt the most advanced equipment to acquire log data. The adopted logging suits include comprehensive logging in openhole and cementevaluation logging in cased hole. Based on the situation of drilling times and programs, eight times of comprehensive logging and five times of cementevaluation logging are designed respectively, and comprehensive logging suits in different drilling times are different; taking into account the challenge of high temperature under the depth of 4500 m, logging items are designed including both required and selected ones. This logging design not only seeks to completely acquire all kinds of log data, but also conduces to flexibly deal with complex conditions of the borehole, which would be beneficial to the achievement of scientific goals.
