摘要:
隨著地下儲氣庫建設、天然氣開發的大規模進行,對油套管螺紋的氣密封性要求越來越高。由于油套管的加工公差配合,運輸過程中的磕碰、微腐蝕,螺紋脂不合理使用,作業過程中上扣扭矩不合理等因素,極易造成螺紋密封性能下降,從而導致油套管泄漏,影響管柱和井筒的完整性與安全性。因此,需要在油套管下井過程中對螺紋連接進行氣密封性能檢測。論述了檢測裝置的液氣動力系統、增壓系統、檢測執行系統、控制系統以及輔助系統的研發、選配等工作。經室內試驗和現場應用表明,研發的檢測裝置操作性強,現場應用效果良好,性能指標達到國外同類產品水平。
Abstract:
With the construction of underground gas storage and the development of natural gas on a large scale, the gas tightness of tubing casing thread is required more and more. Due to the processing tolerance of oil casing, bump and microcorrosion during transportation, unreasonable use of thread grease, and unreasonable torque during operation, etc., the sealing performance of oil casing declined easily, leading to the leakage of oil casing and affecting the integrity and safety of pipe string and wellbore. Therefore, it is necessary to test the gas sealing performance of thread connections during casing running. The development and selection of the hydropneumatic power system, supercharging system, test execution system, control system and auxiliary system of the testing device are discussed. The laboratory test and field application show that the developed testing device has great operability and application, the performance index reaches the level of similar foreign products.
