摘要
中原油田钻井四公司在文明寨油田钻成了3口拔套侧钻井,与?139.7mm套管开窗侧钻井相比,很好地解决了小尺寸钻头机械钻速低和小井眼固井质量差两大难题,开辟了油气井大修新途径。文中详细叙述了拔套侧钻工艺技术,对今后进一步开展拔套侧钻施工具有一定的指导意义。
Abstract
A new sidetracking technology is conducted in Zhongyuan Oilfield, which leads the sidetracking in the original open hole with the casing pulled out. Comparing with window milling in the 139.7mm casing, this technology avoids the use of small size bit and the difficulty of cementing in the slim-hole, thus greatly improves ROP and the cementing quality. Casing pulling operations and sidetracking in 3 wells are described in detail, and it proves to be a good alternative to conventional sidetracking in cased wells.
