长庆油田压裂工艺技术的现状及发展方向

Fracturing Technology Status and Development Direction of Changqing Oilfield

压裂工艺技术是长庆低渗透油层试油、气配套技术的重要组成部分,也是提高单井产量和增加可采储量的关键技术,在长庆低渗、特低渗油、气田开发中具有特殊的地位。经过多年研究及现场试验与改进推广,形成了针对不同储层和油藏条件的一整套完备的增产措施技术模式,为实现低渗透油田高效勘探、经济有效开发提供了重要技术手段。通过对长庆油田压裂工艺的总结,探讨了油田压裂技术发展方向。

Fracturing is not only the important component of oil test to low-permeable oil (gas) reservoir and gas matching technique in Changqing oilfield. But also is the key method to improve single well production and recoverable reservoirs. It is in the special position for development of Changqing low-permeability, ultra-low permeability oil (gas) field. Through many years' research by lots of technical personnel, locale experiments, improvement and actively application, a suit of completed stimulation technology model has been formed for different reservoir conditions, which provides an important method to effectively exploration and develop low-permeability oil (gas) field. By summarizing fracturing tech in Changqing Oil field, development direction has been discussed.
