摘　　要：2018年西部钻探首次在苏里格气田项目经理部的召51区块进行小井眼的开发试验。总共完成9口小井眼的固井施工,固井质量合格率100%。苏里格召51区块属于鄂尔多斯盆地伊陕斜坡,该区块属于低压、低渗、致密气田,分析固井存在的难点以及风险,进而从固井工艺以及水泥浆体系等方面着手,形成小井眼的固井技术与措施,提高该区块小井眼气井的固井质量。In 2018,western drilling carried out the development test of slim hole in zhao51 block of Sulige gas field project management department for the first time.A total of 9 slim holes have been completed,and the qualified rate of cementing quality is 100%.Block 51 of suligezhao belongs to Yishan slope of Ordos Basin,The block belongs to a low pressure,low permeability and tight gas field.The difficulties and risks of cementing are analyzed,Then,from the aspects of cementing technology and cement slurry system,the cementing technology and measures to form slim hole are proposed to improve the cementing quality of slim hole gas wells in this block.
