摘要:
近年來,一種新型纖維增強熱塑性復合管開始在井下分層精細注水領域進行應用。研究了該復合管用于油田井下注水時在組合載荷作用下的尺寸及力學性能的變化規律。選取中國石油吉林油田某油井作為研究對象,該井井深1 000 m,正常注水壓力25 MPa,選取了上、中、下三處典型位置的組合載荷,并模擬管柱多種使用工況。試驗過程中測量復合管的尺寸變化,模擬試驗完成后進行破壞性試驗,最終得到40 ℃和60 ℃下爆破值較常溫分別下降7.6 %和11.6 %,說明溫度對復合管爆破壓力有較大影響。并且在一定溫度范圍內,軸向力和管材的伸長率幾乎呈線性關系,內壓對管材伸長具有一定的抑制作用。通過對組合載荷下復合管力學性能變化規律的研究,有助于指導該類型復合管更好地應用于井下注水領域。
Abstract:
In recent years, a new type of fiber reinforced thermoplastic composite pipe has been applied in downhole precision water injection. The main research content of this paper is to find the variation of geometrical dimensions and mechanical properties of this kind of pipes when used as downhole water injection pipe under combined loads. An oil well in Jilin Oilfield was selected as the research object. The well depth is 1 000 m,the normal water injection pressure is 25 MPa. Combined loads at three typical locations of upper, middle and lower were selected to simulate various operating conditions of pipe string. During the test, the geometrical changes of the composite pipe were measured. After the simulation test was completed, the destructive test was carried out. Finally, the burst pressure at 40 ℃ and 60 ℃ decreased by 7.6 % and 11.6 % respectively compared with that at the normal temperature. The results show that temperature has great influence on the burst pressure of composite pipe. Furthermore, within certain temperature range, the relationship between the axial force and the elongation of the pipe is almost linear. However, the internal pressure has an inhibitory effect on the elongation of the pipe. It is helpful for this type of composite pipe to be better applied in the field of downhole precision water injection by studying the variation of the mechanical properties of the composite pipe under combined loads.
