摘　　要：深层钻井取心是精细研究低孔渗致密储层的有效手段,而确保取心作业成功是开展储层实物研究的前提。文章通过分析曹妃甸A油田东三段致密砂砾岩沉积储层特征以及川式高强度取心工具在东三段砂砾岩储层中的应用,提炼了古近系硬质砂砾岩储层钻井取心的一系列技术措施,包括卡准取心层位,选择合适的取心工具,细化取心作业中每一道工序的具体实施措施,保证了深层砂砾岩取心的高收获率,为后期同类型致密储层的油藏开发提供参考。Deep drilling coring is an effective method for f ine study of low porosity and permeability tight reservoir,and ensuring the success of coring operation is the premise of physical study of reservoir.By analyzing the characteristics of tight sandstone sedimentary reservoir in the east third member of Caofeidian A oilf ield and the application of Sichuan high strength coring tool in the east third member of the oilf ield,this paper ref ines a series of technical measures for drilling coring in the paleogene hard sandstone conglomerate reservoir,including sticking the core horizon,selecting the appropriate coring tool,and ref ining the specif ic implementation measures of each process in the coring operation.It ensures the high yield of deep sand conglomerate core,and provides a reference for the development of the same type of tight reservoir in the later period.
