土耳其盐穴储气库是中石化在国外的首个盐穴储气库钻井项目,盐层取芯为首次采用。通过分析影响盐层取心的主要难点,结合常规取心工具在易碎地层的取心经验,优选取心工具、优化取心工艺,制定出盐层长筒取芯配套工艺技术。在实际的盐层取芯现场施工中,平均收获率达到96%以上,高质量地完成了盐岩层取心任务,为盐岩层分析和后期钻井提供了准确可靠的岩心资料。 The Turkish salt cavern gas reservoir is the first salvage gas reservoir drilling project undertaken by Sinopec abroad. The coring of the salt cavern is the first time it is adopted. By analyzing the main difficulties that affect the coring of the salt coring, combined with the coring experience of conventional coring tools in the fragile formation, the coring tools are optimized and the coring process is optimized. In the field of actual salt coring on-site construction, the average yield was over 96%, and the coring task of salt rock formation was completed with high quality, which provided accurate and reliable core data for salt rock formation analysis and post-drilling.
