辽河边台潜山双分支鱼骨水平井钻完井技术
|
摘要
分支水平井技术的进步使得开发低品质块状潜山高凝油藏的经济效益日渐凸显。在论述辽河油田边台潜山北构造地质特征的基础上,重点介绍该区块基于系统设计理念的短水平段双分支鱼骨水平井井身结构优化设计技术,分析该区钻完井施工的工艺技术难点,总结了钻井施工关键技术和利用套管外封隔器施工的TAML4级完井技术。辽河油田经过多年的复杂结构井开发实践形成的较为成熟的潜山油藏开发技术,具有一定推广应用价值,可供国内开发类似潜山油藏借鉴。
The improvements of multi-lateral well make the development of the high condensation oil reservoir in block buried hill with low quality gets more and more economic benefits.Firstly,this paper introduced the northern tectonic geological characteristics of Bian-tai buried hill in Liaohe oil field,and then mainly introduced the optimal design techniques of the casing program for the fish bone dual-lateral well with a short horizontal section based on the systematic designing concept,and analyzed the technical difficulty of drilling and completion,and summarized the key techniques of drilling and the TAML4 completion techniques by using the external casing packer at last.The mature technology for developing buried hill reservoir has been formed based on the long term development practice with complicated structure well in Liaohe oil field,and it has regular value for popularization application,it can be referred for developing similar buried hill reservoirs for other national oilfields.
