Abstract

The bop sealing device for testing of layered water injection well is the supporting tools for blowout preventer of layered water injection well test. Many problems exists in the traditional sealing device, such as difficulty for down-pass instruments in testing initial stage, cable bending caused by the shaking of spring docking instrument, testing interruption caused by thorn water, gland has only one handle which is not convenient for rotation, need to be integrally replaced after sealing device main body broken, etc. Aiming at these design problem, a new bop sealing device for testing of layered water injection well is invented, and the low test efficiency, easy to stab the water environmental pollution in the process of test, cable loss more single well test cost increasing problems caused by technique defects of traditional device are solved. From the scene of the experimental area, the new spray seal parts structure size design is reasonable, possess the functions of oil lubrication, cable bending, realizing secondary seal, and rapid unloading gland, etc. After measuring by 26 teams application, the test time is saved for 20 minutes for each single team, cable free from wrecked, saving the cost by 5%, benefiting RMB 570,000 per year. Currently, the new type bop sealing device for testing of layered water injection well is popularized and applied in oilfield for more than 300 sets, the application effect is favorable, effectively improve the test efficiency and has a great application promotion value.
