摘要
介绍了苏丹六区钻井取心工具及技术,分析了保形取心和玻璃钢取心工具的结构特点,结合苏丹六区地质特征,通过改进取心工具、优选取心钻头、合理选择钻进参数等措施,解决了该地区松散地层取心收获率低、常规取心岩心质量差等问题。
This paper introduces the coring tools and technique of block six in Sudan, especially the structural features of coring which formation kept technique tool and fiber glass coring tool. The problem of low coring recovery rate in unconsolidated formation and bad core quality is solved by tool improvement, optimizing the coring operations, drilling parameter.The selection of coring bite based on the status of stratum of block six in Sudan. It summarizes some experience about core drilling in block six and offers useful references for other wells in other areas in Sudan.
