利用水平井技术提高新庄南三块稠油油藏储量实践及认识

Practice and recognition of using horizontal well technology to improve Xinzhuang south 3 block heavy oil reserves

摘要: 河南油田新庄南三块地质储量405.6×104t,由于油质稠、厚度薄或受边水的影响,利用直井无法实现经济有效开发。2008年以来,通过水平井开发技术研究,形成了一系列水平井开发薄层稠油的主要技术。该技术现场实施取得了较好的开发效果,有效地解决了目前直井开发薄层稠油所遇到的难题。

Abstract: The geological reservoir quantity of Xinzhuan south 3 block in Henan oilfield is 405.6×104 t.Because the oil layer is viscous,thickness is thin or influenced by edge water,Using vertical well can't realize the effective and economic development.Since 2008,through horizontal well development technology,a series of horizontal well developing thin layer heavy oil technology have been formed.The site implementation of this technology have gained good development effect and,and effectively solved the problem which is met in the vertical well developing thin layer heavy oil.
