摘要/Abstract

摘要： “十三五”期间，为改变传统井下作业“脏、险、苦、累”现状，大庆油田开展了清洁化、自动化作业技术研究与应用。按照“井液不出井、出井不落地、落地不污染”绿色作业要求，针对井下作业过程中井液出井污染环境问题，攻关形成了以井筒溢流控制为主、地面集液回收为辅的清洁化作业技术系列，累计应用20.8万井次，回收废液382.7×10⁴m³，减少固体废物6.3×10⁴t，清洁作业覆盖率由23.6%提升到100%。针对传统井下作业劳动强度大、安全风险高的特性，发展形成了小修、大修自动化作业技术，通过配套自动化作业装备，单队操作人员比例降低25%，年节约人工成本100万元以上，劳动强度和安全风险大幅降低。清洁化、自动化技术的发展与应用实现了井下作业安全、绿色、高效施工，推动了劳动组织方式和生产运行模式的变革。

Abstract: Daqing Oilfield focused on research and application of clean and automation service technology to change the traditional downhole service conditions of formation damage, safety risk and high labor intensity during the 13^th Five-year Plan period. The green service requires “no fluid out of the well, no fluid on the ground, and no environmental pollution on the ground surface”. A series of clean service technologies focusing on wellbore overflow control with the effects on surface fluid collection and recovery was developed to solve the environmental pollution issues caused by fluid out of the well. This technological series was used cumulatively for 208,000 well times, recovering waste liquid for 382.7×10⁴m³ and reducing waste solids for 6.3×10⁴t. The coverage rate of clean service was raised to 100 percent from 23.6 percent. The automated service technology for workover was developed in the efforts to alleviate high labor intensity and high safety risks of downhole service. Development and application of systematic automated service equipment reduced the service personnel proportion of a single crew by 25 percent, saving labor cost for more than 1 million yuan a year and dramatically lowering labor intensity and safety risks. Development and application of clean and automation technology brought about safety, greenness and high-efficiency of downhole service and promoted transformation of labor organizational mode and production operational pattern.
