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

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.
