随着油田开采时间的延长,油水井服役年限随之增加。各类井下卡钻落物事故频繁发生。加之超深井、侧钻开窗井、水平井等特殊井身结构井增多,使井下作业环境日益复杂。井下作业伴随安塞油田的发展同样有二十多年的里程,二十多年的井下作业历程积累了丰富的经验,开发研制了大量作业工具。但现有的井下作业设备、技术、作业工具还是不能满足生产现场的要求。引进新设备、新技术、新的作业工具、提高作业人员技术水平是提高井下作业质量有效解除事故的唯一出路。
With the extension of oilfield mining time, the service life of oil and water wells will increase accordingly. All kinds of downhole card accident occurs frequently. In addition, ultra-deep wells, side-drilled windows and wells, horizontal wells and other special well structure wells increased, making the work environment increasingly complex underground. Downhole operations with the development of Ansai Oilfield also have more than 20 years of mileage, 20 years of underground operations has accumulated rich experience in the development of a large number of operating tools. However, the existing downhole operation equipment, technology and operating tools still can not meet the requirements of the production site. The introduction of new equipment, new technologies, new operating tools, and improvement of the technical level of workers is the only way to improve the quality of underground operations and effectively eliminate accidents.
