摘　　要：双靶定向井技术在开发复杂断块油气田中有其独特的作用 ,在油田开发中后期的增储上产中也是一种特别有效的手段。文中就近几年来双靶定向井技术在中原油田开发调整中的应用及其效果作了简要概述。中原油田几年来的实践证明 :双靶定向井钻遇油层厚度比直井多 1 / 4 ,钻穿同一油层厚度比直井多一倍 ,投产后的产油量比直井多 1～ 2倍 ,钻井成本比直井增加 1 0 %～2 0 %。中原油田目前双靶定向井的平均井深 3 0 4 9m ,最大井深 3 50 0m ;平均井斜 3 6.2°,最大井斜60 .5°;平均位移 1 61 .7m ,最大位移 4 4 3 .0m。The directional wells have played special role for the development of fault block in Zhongyuan Oilfield.Combining the practical experience and comparation with the straight wells,the directional wells have more advantages,the drilled oil zones are more than 1/4,the thickness of the same zone is 1 time over,the oil production after the oil field was put into production is more than 1 2 times, and the drilling cost is increased 10% 20% over.The average driling depth of the horizontal well is deep 3049 m,the biggest is 3500 m;The average inclination is 36.2°;the biggest is 60.5°;and the average displacement is 161.7 m,the biggest is 443 m。Therefore,the twin targets directional well technique has made specific action on the development of complicated fault block oil field,especially for the increasment of reserves and production at the middle late period of the oilfield development.
