【正文】 on transformation in view of this kind of condition under Daqing petroleum administrative bureau mine shaft well drilling pany39。s coordination to this oil field drilling machine。 finally elaborates this system technological transformations plan. The scene movement situation indicated that this frequency conversion system performance well, which the reliability is high and the ease of operation, its each target has achieved the transformation anticipated effect. We believed the inverter will be able to have the broad market and the development potential on oil field drilling machine successfully. Key words: Oil field drilling machine Frequency conversion system 一、引 言 油田鉆機(jī)是油井生產(chǎn)的最主要的設(shè)備之一，它的正常運(yùn)轉(zhuǎn)和工作效率直接關(guān)系到油井的經(jīng)濟(jì)建設(shè)和成井率 。 由于其鉆井工藝的特殊性，對鉆機(jī)電控設(shè)備要求特別苛刻，特別在變頻器選用上非常謹(jǐn)慎，一直是國外產(chǎn)品的天下。由于國外變頻器存在價(jià)格昂貴，調(diào)試周期長，維修周期長的缺點(diǎn)，油田上因變頻器故障卻得不到及時(shí)維修造成質(zhì)量事故的現(xiàn)象時(shí)有發(fā)生。并且國外變頻器在結(jié)構(gòu)上采用變頻器并聯(lián)的形式，占地面積大，給井隊(duì)搬家?guī)聿槐匾穆闊Ｔ谶@種形式下，我們針對鉆機(jī)的特殊工況，自主研發(fā)了可替代進(jìn)口機(jī)的高性能國產(chǎn)鉆機(jī)專用變頻器。該變頻器采用單元并聯(lián)，體積小，重量輕，便于安裝、維護(hù)，調(diào)試容易，效率高，性能穩(wěn)定。 變頻驅(qū)動(dòng)鉆機(jī)較傳統(tǒng)鉆機(jī)有以下優(yōu)點(diǎn)：節(jié)能，操作
