摘要
青海油田自然环境恶劣、社会依托条件差,急需依靠先进的设备和工艺弥补自然条件的不足。借助集团公司连续管新技术推广专项平台,从油田实际情况出发,积极发挥连续管作业周期短、事故率低、地层伤害小和重入性好等优点,转变发展模式,持续技术创新,促进规模应用。建立起高水平的专业化技术服务队伍,形成了低压气井连续管氮气泡沫冲砂作业工艺、连续管通洗井一体化作业工艺、连续管注水井除垢等特色工艺,年作业量连续4年实现国内领先,达到国际规模应用的先进水平,实现了高原井下作业由低端劳务型向现代井下作业技术服务模式的转变,取得了显著的综合经济效益,推动了油气工程技术发展。连续管作业技术的成功推广,为油田推广高端技术成果、提升自主创新能力和工程技术服务水平、实现良好的经济效益提供了借鉴。
Qinghai Oilfield urgently needs the latest equipment and process technology to offset the harsh natural environment and poor social logistic conditions.With the help of the special platform provided by CNPC to extend new technology of coiled tubing,Qinghai Oilfield actively combined a series of advantages of coiled tubing-short service period,low accident rate,small formation damage and easy tripping-in-with its own actual conditions and conversed development pattern for continualtechnological innovation and application on a larger scale.The oilfield established a high-quality specialized technological service crew and developed a series of characteristic processes,such as low-pressure gas well coiled tubing nitrogen foam flushing service process,coiled tubing flushing well integrated service process and coiled tubing injecting well scale-removingprocess.With the annual service amount leading the nation for four consecutive years,the scale application has reached the advanced international standards,Qinghai Oilfield brought about conversion of plateau downhole service from low-end labor service to modern downhole operational technological service,achieving remarkable integrated economic performance and promoting oil and gas engineering technological development.Extension of coiled tubing service technology allowed Qinghai Oilfield to put high-end technological results into wide application,improve its independent creating ability and engineering technological service level,and make a satisfactory economic performance..
