【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(wèn)題而設(shè)計(jì)的一種石油鉆井工具,該閥可實(shí)現(xiàn)外循環(huán),使用方便,安全可靠。國(guó)外公司已有成熟的商業(yè)應(yīng)用,國(guó)內(nèi)目前對(duì)此研究較少,未見(jiàn)相關(guān)報(bào)道。文章設(shè)計(jì)了一種多次激活井下旁通閥,詳細(xì)闡述了多次激活井下旁通閥工作原理,主要通過(guò)投球憋壓的方式實(shí)現(xiàn)旁通的開(kāi)關(guān)。由于閥本體需要開(kāi)孔且受到拉伸、扭轉(zhuǎn)、內(nèi)壓等復(fù)雜載荷,并運(yùn)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(shí)際工況下,對(duì)所設(shè)計(jì)的井下旁通閥結(jié)構(gòu)進(jìn)行了結(jié)構(gòu)強(qiáng)度分析,結(jié)果表明該結(jié)構(gòu)強(qiáng)度上滿(mǎn)足設(shè)計(jì)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.
