白庙凝析气田水平井多段压裂技术的实践与认识

Practice and Understanding of Multi-Stage Fracturing Technology to Baimiao Condensate Gas Field in Horizontal Well

白庙气田属构造复杂,储层变化大,物性差的低渗—特低渗高含凝析油气藏,采用衰竭式开发方式开发,效果很差。尝试应用水平井技术进行改善开发效果试验,由于水平井压裂工艺限制,效果不理想。应用非常规油气藏开发技术,对白庙凝析气田白庙平1井进行多段压裂改造,取得了良好的增产效果,为改善白庙复杂断块凝析气田的开发效果探索出了一条有效的技术思路。

Baimiao gas field belongs to the low and extra low permeability condensate gas reservoir of being complex structure,big changes of reservoir,poor physical property,the effect to which failure development approach is taken is very poor. Applying horizontal well technology to improve the development effect,due to the limitation of horizontal well fracturing,the effect is not ideal. Application of unconventional oil gas reservoir development tech,multi-interval fracturing to Baimiao condensate gas field in Baimiao horizontal 1 well is operated,and good effect of increasing yield is achieved,which explores an effective technical way for development of improving Baimiao complex fault block in condensate gas field.
