PILOT APPLICATION OF VIBRATION CEMENTING TECHNIQUE IN LIAOHE OILFIELD

As a new cementing technique, vibration cementing technique is developed to improve quality of cementing, based on the principle of vibration in concrete placement in construction sector. This paper mainly presents development and principle of downhole pulse vibration. The field application of vibration cementing technique is also discussed. The field application indicates that vibration cementing technique not only improves the flowability of slurry and shorts initial and final setting times as well as hardening time, but also increase hardness of cement and lasts the working life of oil wells.
