Drilling Construction Technology of Well Qiping 3

摘要:

齐平3井是部署在松辽盆地中央坳陷区齐家凹陷的一口水平探井，完钻斜深3574.03 m，垂深2201.1 m，水平段长1195.35 m。在施工前对井身结构和井眼轨迹剖面进行了优化设计，施工中应用井眼轨迹控制技术、地质导向技术，并配以钻井安全施工工艺，保证了该井的顺利完钻，实现了设计要求的各项技术指标，取得了良好的施工效果。

Abstract:

Qiping 3 is a horizontal well in Qijia depression at central depression area of Songliao basin with slant depth of 3574.03m, vertical depth of 2201.1 m and horizontal section length of 1195.35 m while finishing drilling. Optimized designs were made on the casing program and well track section before the construction, and hole trajectory control and geo-steering as well as drilling safety construction technologies were applied during the construction to ensure the smooth operation and achieve the various technical indicators in the design with good effects.
