应用分支水平井技术开发低渗透高凝油油藏

Applying Branch Horizontal Well Technology to Develop the Low Permeability and High Pour-Poing Oil Reservoir

针对静 1 7块存在单井产量递减快 ,注水井发效果差等一系列问题 ,在综合研究论证基础上 ,应用分支水平井技术开发低渗透高凝油油藏 ,使得静 1 7- 31 - 5 9FP井在投产初期产量达到近 2 0t/d ,至今仍稳产在 1 3t/d。为分支水平井技术在类似油藏中的应用提供有益的借鉴作用。

To a series of questions existed in the Jing 17 block,such as fast decrease of individualwell producing rate,and bad effect of waterflooding etc On the basis of integrated study and demonstrate,and applying the branch horizontal well technology to develop the low permeability and high pour point oil reservoir The production of Jing 17 31 59FP well was up to 20 t/d at early stage,and still stable at 14t/d at present.It provides the profitable reference effect for the similar oil reservoir to apply branch horizontal well technology
