加强排水采气工艺前期论证提高工艺措施效果

STRENGTHENING EARLIER STAGE PROOF OF DRAINAGE GAS RECOVERY TECH- NOLOGY TO IMPROVE THE EFFECT OF PRO- CESS MEASURES

蜀南气矿气田进入开发后期主要依靠排水采气工艺维持生产,目前新上工艺措施井都是一些地层压力较低、修井作业技术难度大、投资风险相对较大的气水同产井,为减少工艺投资风险,必须加强工艺措施的前期论证。文中对气矿后期开发潜力进行了认真分析,对排水采气工艺技术进行了总结与技术评价,提出了工艺技术前期论证的方法并列举实例。

In later - period oil field development, Shunan gas field depends on drainage gas recovery technology to maintain production. At present, formation pressure of some producing wells with water and gas are very low, workover job is difficult, and investment risk is great. In order to decrease investment risk, the earlier stage proof of process measures must be strengthened. The paper analyses the potential of later - period development in Shunan gas field, summarizes and evaluates the drainage gas recovery technology, and proposes the methods on earlier stage proof of the technology.
