安徽北部地区小口径地质调查井施工技术研究

Drilling technology for small diameter geological survey wells in northern Anhui

摘要:

皖亳地1井是部署在安徽省亳州市谯城区境内的一口油气调查井，该井旨在通过钻探、录井、测井等工作方法查明安徽亳州地区地层层序及发育特征，获取寒武系储层物性及含油气性等评价参数。本文详细介绍了该井的地质概况、钻探施工技术及施工中遇到的难题，并提出了针对性解决方案，圆满完成了各项施工任务，可为国内同类型小口径地质调查井施工提供经验及借鉴。

Abstract:

Well Wanbodi-1 was an oil and gas survey well deployed in Qiaocheng district， Bozhou city， Anhui province. The purpose of this well was to find out the stratigraphic sequence and development characteristics in Bozhou district， Anhui province by drilling， logging and testing methods， and to obtain the evaluation parameters of Cambrian reservoir physical properties， and oil and gas properties. The geology， drilling technology and problems encountered in well drilling are introduced in detail with the specific solutions put forward. The successful completion of the drilling work can provide experience and reference for drilling of similar small-diameter geological survey wells in China.
