涪陵页岩气水平井定向技术

涪陵页岩气产能示范区作为国内首个国家级页岩气示范区,自2012年启动以来,通过不断的技术攻关和技术创新,形成了完善的国产化水平井钻井技术系列。2015年随着区块的转移,地质条件更趋复杂,定向施工面临着更多新的技术难题,在已有成熟技术的基础上,通过技术优化和先进的降摩减扭工具的应用,有效地解决了新区块的施工难题,推进了页岩气产能区的建设。

Directional Technology of Shale Gas Horizontal Wells in Fuling Area

As the first national shale gas demonstration area, Fuling shale gas productivity demonstration area was started in 2012. Through continuous technological research and innovation, a perfect domestic horizontal well drilling technology series has been formed. With blocks transfer in 2015, the geological conditions became more complex, new technical difficulties were encountered in directional construction. On the basis of the existing mature technologies, by the technology optimization and the application of advanced friction and torsion reducing tools, the construction difficulties in new blocks have been effectively solved, which promotes the construction of shale gas productivity zone.
