【摘要】：為了合理分析水力振蕩器的振動特性影響因素,文中根據(jù)水力振蕩器在井下的實際工況,通過條件假設(shè)、模型簡化,建立了關(guān)于水力振蕩器井下工具組合的振動分析模型,選取合適的鉆井參數(shù),分析得到水力振蕩器在靜閥板中心孔直徑不同、相對鉆頭的安放位置不同時的振動特性。通過室內(nèi)實驗與下井試驗,進一步分析這2個重要參數(shù)對工具振動特性的影響。研究表明:隨著靜閥板中心孔直徑的增大,水力振蕩器的振動位移和振動速度均逐漸減小;隨著安放位置與鉆頭距離的增大,水力振蕩器的振動位移和振動速度均逐漸增大。研究結(jié)果對下井工藝的應(yīng)用具有重要指導(dǎo)意義。
[Abstract]:In order to reasonably analyze the factors affecting the vibration characteristics of the hydraulic oscillator, according to the actual working conditions of the hydraulic oscillator in the underground, the vibration analysis model of the hydraulic oscillator downhole tool combination is established by the assumption of the conditions and the simplification of the model. By selecting appropriate drilling parameters, the vibration characteristics of the hydraulic oscillator with different diameter in the center hole of the static valve plate and different placement position relative to the bit are obtained. The effects of these two important parameters on the vibration characteristics of the tool are further analyzed through laboratory and downhole tests. The results show that the vibration displacement and velocity of the hydraulic oscillator decrease gradually with the increase of the diameter of the center hole of the static valve plate, and the vibration displacement and velocity of the hydraulic oscillator increase with the increase of the distance between the placement position and the bit. The results are of great significance to the application of downhole technology.
