【摘要】：针对俄罗斯移动式振动器启动困难和不能长时间工作的缺陷,通过研制井下振动器和简化压力平衡机构,根据力学分析优化振动器偏心块的结构,并配套地面电控系统,形成了适用φ139.7mm套管的移动式振动固井装置。地面试验表明,移动式振动固井装置适用于井斜角不大于50°的井段,启动容易,可以长时间工作。在胜利油田营13-斜161井的现场试验表明,采用移动式振动固井装置进行振动固井井段的固井质量显著提高,与未采用振动固井的邻井相同井段相比,第一界面优质率和第二界面合格率分别平均提高17.5和45.0百分点。研究表明,自主研发的移动式振动固井装置克服了俄罗斯移动式振动器的缺陷,适用于井斜角不大于50°的井段,能够有效提升第一、二界面的胶结质量。
[Abstract]:In view of the difficulties of Russian mobile vibrator in starting and not working for a long time, through the development of downhole vibrator and simplified pressure balancing mechanism, the eccentricity block structure of vibrator is optimized according to mechanical analysis, and the ground electric control system is matched. A movable vibratory cementing device suitable for 蠁 139.7mm casing is formed. The surface test shows that the mobile vibratory cementing device is suitable for the section with inclined angle less than 50 掳, which is easy to start up and can work for a long time. Field tests in Ying13- inclined 161 well in Shengli Oilfield show that the cementing quality of vibrating cementing section with mobile vibratory cementing device is significantly improved, compared with the same section of adjacent wells without vibration cementing. The quality rate of the first interface and the qualified rate of the second interface increased by 17.5% and 45.0% respectively. The study shows that the self-developed mobile vibratory cementing device overcomes the defects of the Russian mobile vibrator and is suitable for wells with a slope angle of less than 50 掳, which can effectively improve the cementing quality of the first and second interfaces.
