随行振动固井的耦合共振效应与应用评价
Coupling Resonance Effect and Application Evaluation of Accompanying Vibration Cementing
摘要
Abstract
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.关键词
