深部成盐盆地大口径绳索取心设备机具的选配

Match of Large Diameter Coring Equipments and Tools for Deep Salt Formation Basin

叶舞凹陷盐矿普查项目需在2000 m以深取心,根据项目书要求,采用小口径岩心钻探与大口径石油、水文水井钻探技术。结合几种类型设备机具的优点,采用石油钻井和绳索取心"二合一"钻探新技术,快速的、经济的、高效的完成了施工任务。介绍了盐矿大口径深部钻探和取心设备机具的选配,可供类似工程项目设备机具的选配借鉴。

In the survey project in Yewu depression salt mine, it was required to core at the depth of more than 2000m un- der the ground surface. According to the requirement of the project book, small diameter core drilling and large diameter petroleum drilling and hydrological well drilling technologies were adopted. With the collection of the advantages of several types of equipment and tool by the new technology of combination of petroleum drilling and wire-line coring , the construc- tion was effectively completed with low cost. The paper introduces the match of equipments and tools for large diameter deep drilling in salt mine, which can be the reference to the similar projects.
