Accompanying vibration cementing technology is a new technology and equipment that can effectively overcome vibration wave attenuation and improve cementing quality during the oil and gas drilling process. In this article

the equipment structure and excitation load of self-developed equipment is first presented

and the coupling resonance excitation mechanism of this technology is also elaborated. Though theoretical analysis and simulation

we obtained the amplitude expression of the resonance of simply supported beam casing

the shock wave pressure function in the fluid

and the shock wave attenuation characteristics in the fluid

and quantified with the vibration response parameters and shock wave characteristics of 30 W equipment in 5-1/2 inch casing cementing. Through application testing in 8 gas wells in Qinghai Oilfield

it has been further verified that this technology is an effective process measure to improve cementing quality.
