摘要
白马庙气田蓬莱镇组气藏属红色陆相碎屑岩远源次生气藏，主要储层为分流河道及河口坝砂岩。蓬莱镇组气藏是典型的中～高孔、低渗、弱超压致密砂岩气藏，储层非均质性强，纵横向变化大，储层宏观裂缝发育较差。该气藏部分井未钻遇分流河道及河口坝砂体最佳部位，导致效果不佳，为有效沟通远井地带储层与井筒，通过再造新的油气渗透通道，增大泄流半径与面积，最终提高单井产能是这类难动用气藏高效开发的关键。水力喷射径向钻孔技术在现场应用取得了工艺和增产效果的成功，值得在气井挖潜中推广应用。
The Penglaizhen formation gas reservoir of Baimamiao gas field belongs to the red continental clastic rocks far source gas reservoir which main pay zone is distributary channel and mouth bar sandstone. Penglaizhen formation gas reservoir is typical tight sand gas reservoir with mid to high porosity and low permeability,strong reservoir heterogeneity,large vertical and horizontal change and with poor macroscopic fracture development. Some wells had not been drilled to the best part of distributary channel and mouth bar sandstone in Penglaizhen formation gas reservoir,leading to poor operation effect. In order to effectively communicate the far wellbore reservoir and the wellbore,the key efficient developing measure is to reengineer a new oil and gas permeability channel,increase the discharge radius and area,and finally to improve the productivity of single well. Application of hydraulic jet radial drilling technology in the field has made much success in the processing and the stimulation. It is worthy of popularization and application in the old gas well potentialities.
