摘要
文古3井是中石油一口重点探井。为了达到保护储层、及时发现油气层和加快文安潜山文古1断块潜山圈闭油气勘探步伐的目的,华北油田根据文古3井潜山地层的具体地质特征,在四开井段应用无荧光水包白油成功实施了欠平衡钻井作业,达到了流钻欠平衡勘探效果,而且钻进过程中欠平衡点火管线一直连续点火燃烧,表明华北油田欠平衡钻井技术初步走向成熟,为今后华北油田古潜山油气藏的勘探开发提供了技术支持和保证。
Well Wengu3 is an important exploration well of Petrochina.In order to protect the reservoir,to discover timely hydrocarbon zones and accelerate the exploration speed in Wenan buried hill of Wengu1 block buried hill of oil and gas traps,and to think about the specific geological feature of well Wengu3,the underbalanced drilling technique of Huabei oilfield was used in the section of Sikai well,which reached effects of flowing drilling underbalanced exploration. In addition,the underbalanced point has been continuous ignition combustion of the ignition line in the drilling process,this indicates that the underbalanced drilling technique of Huabei oilfield preliminary mature,and provide the technical support and guarantee for the future exploration and development of oil and gas reservoirs in ancient buried hill of Huabei oilfield.
