“井工厂”技术能大幅度提高作业效率、降低工程成本，在致密油气、页岩油气等低渗透、低品位的非常规油气开发中具有显著的技术优势，因此该技术在北美地区进行了大规模应用，取得了巨大的经济效益。为了使该技术更好地应用于我国非常规油气开发中，在详细阐述“井工厂”技术的概念和特点的基础上，介绍了国外该技术的发展和应用现状，梳理了国内中国石油、中国石化对该技术的探索应用情况，并分析指出，国内配套的装备仪器还不能完全适应“井工厂”作业的需求，还没有实现真正意义上的流水线式施工，还没有形成一套成熟的“井工厂”作业模式。因此，建议树立“全过程低成本”的基本理念，总结我国致密气藏开发的成功经验，有针对性地集成和发展相配套的工程技术，设立“井工厂”技术项目部，规范管理，以形成真正符合我国非常规油气资源类型和开发规律的“井工厂”技术。

Multi-well pad technology can improve drilling efficiency and save cost ,so it has an advan-tage in developing tight gas ,shale gas and unconventional oil and gas ,it had been widely used in North A-merica and got huge economic benefits .In order to speed up the popularization of multi-well Pad technology in the development of unconventional oil and gas in our country ,this paper analyzed the status quo and ap-plication of multi-well pad in other countries by introducing the concept and characteristics of multi-well pad technology .The application of multi-well pad technology in PetroChina and Sinopec were summarized . Comparison and analysis indicated that domestic equipment can not meet the demand of multi-well pad technology now ,the production line for drilling is still not perfect ,and a set of well-factory operation modes hasn’t taken shape .It was recommended that corresponding engineering technology should be integrated and developed ,and multi-well pad department should be established based on the low cost concept to form a set of well-factory technologies suitable for developing unconventional oil and gas resources in China .
