阐述了中原油田应用于低压易漏井的3 项固井技术及其应用效果,即高强低密度水泥浆技术、前置低密度钻井液固井技术和双级注水泥技术。结果表明,这3 项固井技术的应用,成功地解决了中原油田目前低压易漏井固井时出现的井漏和固井质量等问题。

This paper illustrates three cementing techniques for the absorption wells of low pressure in Zhongyuan Oilfield , they are cementing techniques of high strength and low density , prepumping low density drilling fluid and two steps cernenting. The applied effect s show that these three cementing techniques have successfully settled the present cenlenting problems of the wells of low pressure and is apt to leak in the oilfield.
