摘要

针对静17 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17 - 31 - 59FP 井在投产初期产量达到近20 t/ d ,至今仍稳产在13 t/ 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。

Abstract

To a series of questions existed in the Jing 17 block ,such as

fast decrease of individualwell producing rate ,and bad effect of

waterflooding etc1On the basis of integrated study and

demonstrate ,and applying the branch horizontal well technology

to develop the low permeability and high pour2point oil

reservoir1The production of Jing 17231259FP 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.
