【摘要】：海洋深水測(cè)試管柱系統(tǒng)是深水測(cè)試的重要設(shè)備之一,其安全問題直接關(guān)系到試油、采油過程的成功與否。在海洋深水測(cè)試過程中,管柱系統(tǒng)受到的沖擊荷載主要來自于以下兩個(gè)工況：射孔工況和隔水管脫開工況。兩種工況產(chǎn)生的沖擊荷載都會(huì)使管柱系統(tǒng)發(fā)生沿管柱軸線方向的振動(dòng),并對(duì)管柱系統(tǒng)上方儀器、設(shè)備等產(chǎn)生沖擊。因此,為了確保在此沖擊荷載作用下,管柱系統(tǒng)與海洋環(huán)境或測(cè)試儀器、設(shè)備等不產(chǎn)生共振及管柱系統(tǒng)、鉆井平臺(tái)的張拉設(shè)備、測(cè)試設(shè)備等不發(fā)生破壞,這就催生出很多管柱系統(tǒng)動(dòng)力學(xué)行為研究方面的問題。如：新型減振器的設(shè)計(jì)、管柱系統(tǒng)在沖擊荷載下的動(dòng)力響應(yīng)、管柱系統(tǒng)模型的建立等,亟待探討和解決。 本文針對(duì)射孔模式及脫開模式下深水測(cè)試管串的安全問題,采用微元法分別建立了考慮管柱自重、管柱實(shí)際長(zhǎng)度、流體摩阻影響的射孔管柱-減振器動(dòng)力學(xué)模型及考慮海洋環(huán)境影響的實(shí)際隔水管串縱向振動(dòng)動(dòng)力學(xué)模型,給出了相應(yīng)的初始條件、邊界條件以及模型的差分格式,編制了相應(yīng)的計(jì)算程序,開發(fā)了相應(yīng)的仿真軟件；并以南海某實(shí)際測(cè)試管串的設(shè)計(jì)為例,分別開展了射孔沖擊荷載作用下射孔管柱的動(dòng)力學(xué)行為研究及脫開模式下隔水管串的動(dòng)力學(xué)行為研究,這對(duì)提高井下管柱系統(tǒng)的安全性能具有重要的理論和實(shí)際意義。
[Abstract]:Marine deep-water test string system is one of the most important equipment in deep-water testing, and its safety is directly related to the success of oil testing and oil recovery. The impact loads on the string system are mainly from the following two working conditions: perforation and riser detaching. The shock loads generated under both conditions will cause the string system to vibrate along the axis of the string. Therefore, in order to ensure that under this impact load, the string system and the marine environment or test instruments, equipment and so on do not produce resonance and string system, the tension equipment of drilling platform, There are many problems in the study of the dynamic behavior of the string system, such as the design of the new damper, the dynamic response of the string system under impact load, the establishment of the string system model, etc. It needs to be discussed and solved urgently. Aiming at the safety problem of deep water test string in perforation mode and decoupling mode, the actual length of pipe string and self-weight of pipe string are established by means of micro-element method. The dynamic model of perforation string and shock absorber affected by fluid friction and the dynamic model of longitudinal vibration of actual riser string considering the influence of marine environment are given. The corresponding initial conditions, boundary conditions and the difference scheme of the model are given. The corresponding calculation program and simulation software are developed, and the design of a real test tube string in the South China Sea is taken as an example. The dynamic behavior of perforated string under perforation impact load and the dynamic behavior of riser string under detaching mode are studied respectively. It is of great theoretical and practical significance to improve the safety performance of downhole string system.
