 杜84 块是辽河油田稠油区块，馆陶组油层存在边顶水，无底水，物性条件比较
好。在采用水平井开发过程中,由于热采造成环空水泥石过早破坏，边顶水锥进严重，缩短了水
平井的寿命。为解决这一问题研制出上翘型水平井工艺技术，并在该区块成功施工杜84-馆平
11 井和杜84-馆平12 井2 口井。介绍了杜84-馆平12 井的设计与施工，总结了上翘型水平井
开采边底水稠油油藏的经验，对同类型油藏的开发具有指导意义。

Block Du84 of Liaohe oil field is a heavy oil block with
top-water and edge-water, no bottom-water. There is a good
physics character in heavy oil reservoir of Guantao Group. The
annular cement of horizontal well is destroyed so early by the
hot steam during the production. The life-span of horizontal
well is shortened because of the top-water and edge-water
coning and the cement destruction. The upturned horizontal
well technology has been developed to resolve this problem
and has been applied to Well Guanping 11 and Well Guanping
12 successfully in the Block Du84. The design and
implementation of Well Guanping 12 is introduced in the
paper. The experience of producing heavy oil reservoir with
top water and edge water by upturned horizontal well is
summed up and it is useful for the same reservoirs.
