摘要/Abstract

摘要： 目前在大斜度井、大位移水平井等钻进施工过程中,井底岩屑实际返出情况是影响钻井安全和钻井周期的直接因素。为了保障钻井安全,提升钻井时效,通过井眼清洁监测系统(BCM),可定量化监测井底岩屑返出情况,为现场第一时间提供井底清洁度和井壁稳定性数据分析,帮助井队不断提高钻井效率,为钻井施工实时预警,减少非生产时间(NPT),BCM采用在地面安装的在线岩屑称重装置,实时采集井筒返出岩屑重量,通过实时岩屑流量、岩屑返出理论体积、实际体积、环空岩屑浓度、综合录井等参数利用工程计算分析方法,实时监测井眼清洁、井壁稳定情况,优化分析钻井时效,可有效预防由沉砂或井壁失稳引起的卡钻事故的发生,并给出相应工程应用实例。该类设备已经在国外钻井市场(大位移井、水平井等)广泛应用,对于实时安全钻井,提高钻井效率以及节省钻井成本具有较高的实用价值。

Abstract: At present,in the drilling and construction of highly deviated wells and extended reach horizontal wells,the actual return of bottom-hole cuttings directly influences drilling safety and drilling cycle. For drilling safety and drilling efficiency improvement,the borehole cleaning monitoring system(BCM)quantitatively monitors the return of bottom hole cuttings and provides data analysis of bottom hole cleanliness and borehole wall stability immediately,helping drilling crew continuously improve drilling efficiency,warning the drilling construction in real time,and reducing non-productive time(NPT). BCM uses an online cuttings weighing device installed on the ground to collect the weight of cuttings returned from the wellbore in real time,and uses engineering calculation analysis methods through real-time cuttings flow,theoretical volume and actual volume of cutting return,annular cuttings concentration,and comprehensive mud logging to real-time monitor borehole cleanliness and borehole wall stability,optimize and analyze drilling efficiency,which effectively prevents sticking caused by sand setting or instability of borehole wall,and provides corresponding engineering application examples. This type of equipment has been widely used in overseas drilling markets,mainly extended reach wells and horizontal wells,and has high practical value for real-time safe drilling,drilling efficiency improvement and drilling costs saving.

Key words: drilling optimization, real-time cuttings flow, borehole cleaning, monitoring system, borehole wall stability, non-productive time
