中长筒取心技术在玛页1井的应用

APPLICATION OF MEDIUM AND LONG TUBE CORING TECHNOLOGY IN MAYE 1

根据玛湖风城组地层特点及历年的取心实践情况,优选取心工具,配套专用的取心钻头,优化后钻井参数等手段,在该区块玛页1井实施螺杆驱动取心工具进行中长筒取心工艺技术,并在取心钻具组合中采用满眼钻头,减少通井时间,获得了预期的效果,大大提高单筒取心进尺,节约钻井周期,降低钻井成本。为后期在该区中长筒应用中长筒取心技术有一定借鉴意义。

According to the stratigraphic characteristics of the Mahu Fengcheng Formation and the coring practice in the past years,coring tools are optimized,special coring bits are used,and drilling parameters are optimized.In this block,a screw-driven coring tool is implemented in Well Maye 1 the medium and long barrel coring process technology is adopted,and full-hole drills are used in the core drilling tool assembly to reduce the time of through-holes and achieve the expected results.The single barrel coring footage has been greatly improved,saving drilling cycles and reducing drilling costs.It has certain reference significance for the application of middle and long tube coring technology in the later period.
