【摘要】：多次激活井下旁通閥是為了解決隨鉆堵漏、隨鉆大排量洗井和卡鉆等問題而設(shè)計的一種石油鉆井工具,該閥可實現(xiàn)外循環(huán),使用方便,安全可靠。國外公司已有成熟的商業(yè)應(yīng)用,國內(nèi)目前對此研究較少,未見相關(guān)報道。文章設(shè)計了一種多次激活井下旁通閥,詳細闡述了多次激活井下旁通閥工作原理,主要通過投球憋壓的方式實現(xiàn)旁通的開關(guān)。由于閥本體需要開孔且受到拉伸、扭轉(zhuǎn)、內(nèi)壓等復(fù)雜載荷,并運用有限元分析軟件ANSYS workbench模擬多次激活井下旁通閥在井下實際工況下,對所設(shè)計的井下旁通閥結(jié)構(gòu)進行了結(jié)構(gòu)強度分析,結(jié)果表明該結(jié)構(gòu)強度上滿足設(shè)計要求。
[Abstract]:Multiple activation of downhole bypass valve is a kind of oil drilling tool designed to solve the problems of plugging while drilling, washing well while drilling and sticking. The valve can realize external circulation, convenient to use, safe and reliable. Foreign companies have mature commercial applications, the domestic research on this is less, there is no related report. In this paper, a multi-activation downhole bypass valve is designed, and the working principle of multiple activation downhole bypass valve is described in detail. The bypass switch is mainly realized by throwing ball holding pressure. Because the valve body needs to be opened and subjected to complex loads such as tension, torsion, internal pressure and so on, the structural strength analysis of the designed downhole bypass valve structure is carried out under the actual underground working conditions by using the finite element analysis software ANSYS workbench. The results show that the strength of the structure meets the design requirements.
