well tube (鉆井)套管。

well- born

Designning well tube and drill - hole diameter in order to increase thickness of both annular packing gravel and water - resisting clay , nylon net packing around well tube filters , designing filter layer on the boundary between packing gravel and water - resisting clay and ramming the gravel by working the piston into the well after gravel packing completion and the filling clay for salt - water resisting etc . we succeeded in constructing 3 drinking - water wells in minqin county , proved the affectivity and feasibility of using it and giving a certain technical demonstration of construction of drinking - water well in the same similar to this area 通過孔徑與管徑的調配設計,增大環狀粒料層和止水粘土層的厚度;濾水管外包尼龍紗網;粒料與止水粘土接觸界面上設計反濾層;填粒后先行拉活塞利用水力夯實粒料層,再投粘土球止掉上部咸水等措施,在民勤縣三口人飲水井施工中取得顯著效果,證明了該套成井工藝的有效性和可行性,有望為同類地區人飲水井施工提供技術示范作用。

Abstract : addressing the problems encountered in localizing oil well tubing production , the co ? authors analyze the influences by aspects , namely , product quality , product r d , operation , technical level of equipment and competition in this specific industrial circles , emphasize the necessity of speeding up localization of oil well tubing production , and find out the elements hindering current development of the said localization 文摘:針對油井管國產化遇到的問題,分析論述了產品質量、品種開發、使用操作、裝備技術及行業競爭的影響,指出了加強油井管國產化的必要性以及阻礙當前發展的原因。

In the light of the status that there are caustic faults in the oil well tubing and there are not effective inspections , in this paper the plane roundness fault model of the is studied , and the magnetic leakage flux distributing model at the direction of the normal of the roundness fault is proposed 針對油管容易遭到腐蝕性損傷而目前缺乏有效檢測手段的現狀,本文系統的研究了平面圓形缺陷模型,提出了圓形缺陷的法線分量漏磁場的實驗分布模型。
