海拉尔油田钻头选型分析

Analysis on Drilling Bit Selection in Hailaer Oilfield

摘要:

根据2007年和2008年海拉尔油田使用的钻头实钻数据，结合其地层特点和钻井工艺，对各层段钻头选型及影响机械钻速的原因进行了分析，并优选出一套适合海拉尔油田使用的钻头序列，对正确选用钻头、提高钻井效率具有指导作用。2009年上半年（截止2009年6月）现场试验表明，钻速较2007和2008年分别提高20%和39%，进尺分别增加21.13%和17.49%，特别是希47-44井和希44-54井，取得了显著的应用效果。

Abstract:

Based on the real drilling data of the bits used in Hailaer oilfield in 2007 and 2008 and according to the formation characteristics and drilling technology, analysis on the bit selection for different layer section and the causes of affecting penetration rate were made, a series of bits fitting to drilling in Hailaer oilfield was selected out. Field test showed that the penetration rate increased 20% and 30% compared with that of 2007 and 2008, footage increased 21.13% and 17.49% and obvious application effect was obtained in Xi47-44 well and Xi44-45 well.
