摘　　要：深分支井一般温度较高、压力较大,从安全角度考虑,双管柱在深分支井中下入的可行性很低,如何采取单一管柱实现对深分支井分采/合采的智能控制是国内外都在不断改进和发展的重要研究方向。设计了一种深分支井分采/合采智能控制的采油管柱,不但实现了分支井分采/合采的智能化,而且可以有效解决目前国内分支井采油面临的几个技术难题:(1)有效解决分支井井间干扰、窜流等问题,能保证各分支的产能得到充分发挥,为用分支井开采裂缝、孔洞型油藏提供了技术支持;(2)无需另行下入专用测试工具及封堵工具,即可找到哪一个分支出水并有效封堵出水分支;(3)能够满足高温、高压井的需要,为用分支井开采较深油层提供了技术支持。The feasibility of double column entering in the deep branch well is very low because of the high temperature and pressure,how to use the unitary column realizing intelligent control of commingled production of deep branch well is important research direction of study and unceasing improvement at home and abroad.The oil extraction is realized intelligent control of commingled production.This column has not only realized the branch selective mining from the branch well and the intelligent commingled production,but can also be used to effectively resolve the domestic oil extraction of the branch well that is confronted with several technology problems,i.e.,effectively resolve the problem of disturbance and channeling inter-branch well,ensure that the productivity of every branch well is bought in full play and provide the technology hold for branch well to extract fracture and pore-type reservoirs,no need to run a specialized test tool and blank off tool and find out the branch producing water,as to effectively blank off the branch,be able to meet the need of the high temperature and high pressure well,provide the technology hold for branch well to extract deeper oil.
