水平井是通过扩大油层泄油面积提高油井产量,提高油田开发经济效益的一项开发技术,具有直井无法比拟的突出优势:1可以实现少井高产,油田高速高效开发;2较大幅度增加泄油面积,提高单井产量;3增加可采储量、提高油藏最终采收率。本文主要总结了利用水平井对古云集沙一中薄油层开发中的技术难点,以及解决这些难点我们采用的技术和在应用中的经验教训,并通过对古云集油田沙一中油藏开发方案的实施,进行验证,达到了很好的经济效益。
Horizontal well is a developing technology that can increase oil well production and increase the economic benefits of oilfield development by expanding oil drainage area. It has the unparalleled outstanding advantages of vertical well: (1) it can realize the production of less well and the high-speed and efficient development of oilfield; (2) Oil area, improve single-well production; 3 increase recoverable reserves, improve the ultimate recovery of the reservoir. This paper mainly summarizes the technical difficulties in the development of thin oil reservoirs in the ancient sand through the use of horizontal wells, as well as the technologies we used to solve these difficulties and the experiences and lessons in their application. Through the exploration and development of the Shayizhong Reservoir Development Project The implementation of verification, to achieve a very good economic returns.
