RECOGNITION OF GAS-BEARING RESERVOIR WITH UNDERBALANCE DRILLING METHOD
-
摘要: 欠平衡钻井是天然气钻探最有效的钻井工艺技术之一,在大港、大庆油田等勘探区域成效显著.欠平衡钻井过程中,气层钻开后,气测井的背景值大幅抬高,甚至达到饱和状态,导致后续气层无法识别.在分析气测井技术局限性的基础上,针对欠平衡钻井工艺的特点,探讨了通过对岩屑进行破碎、脱气和含气分析,对地层含气情况进行识别和评价的方法,并给出了应用实例.Abstract: Underbalance drilling is one of the most effective drilling technologies in natural gas exploration.Good results have been made in the prospecting areas of Dagang Oilfield and Daqing Oilfield,et al.Some forward requirements for the identification and evaluation of geological logging with drilling gas-bearing reservoirs have been carried out by the application of underbalance drilling technology.In this paper,the localization of logging techniques for gas has been analyzed,and the application method of cutting gas analysis technology for recognition gas-bearing reservoirs in natural gas exploration has been discussed on the basis of characteristics of underbalance drilling technology,and some application examples have been shown.
