中文摘要:在浅层气区进行小口径岩心钻探,最重要的是井控防喷技术。发生井喷是钻探施工中最严重的事故。根据地质岩心钻探特点,针对浅层气埋藏浅、在区块内分布范围广、发生井喷的概率大、施工风险高等高危特征,制定了在浅层气地区进行小口径岩心钻探施工的工艺技术;按照《大庆油田钻井井控实施细则》(征求意见稿)相关规定,结合大庆长垣南浅层气区地质条件,以及地质钻探全孔取心要求,制定了小口径岩心钻探井控设备配置标准和技术措施,以确保安全生产,不发生井喷事故。

Research on Well Control and Blowout Prevention Technology for Small Diameter Core Drilling in Shallow Gas Area of Daqing Oilfield
Abstract:The well control and blowout prevention is a most important technology in small diameter core drilling in the shallow gas area, for blowout is the most serious accident in drilling construction. According to the geological core drilling characteristics, and in view of the high risks characteristics of shallow gas such as shallow buried depth, wide distribution in the block, large probability of blowout and high risk of construction, the small diameter core drilling construction technical methods in shallow gas area are worked out; according to the relevant regulations of “Implementation Details for Well Control in Daqing Oilfield Drilling”(draft for comments), and combining the geological conditions in shallow gas areas in southern Changyuan of Daqing as well as the requirement of full hole coring in geological drilling, the well control equipment configuration standard of small diameter core drilling and technical measures are established to ensure safe production and no blowout accident.
