管柱脫落是自由式管柱結(jié)構(gòu)經(jīng)常發(fā)生的一種現(xiàn)象,這是由于正常運轉(zhuǎn)時轉(zhuǎn)子旋轉(zhuǎn)對定子產(chǎn)生的摩擦扭矩方向?qū)嶋H上是定子及油管的連接螺紋的卸扣方向,莫諾,如果摩擦力矩大于油管扣的上扣扭矩,油管就脫扣。當尾管很重時,還會出現(xiàn)螺紋擄扣。當管柱脫落時,通過作業(yè)重新連接好就能恢復生產(chǎn)。如果未發(fā)生螺紋擄扣,可以采取對扣方式打撈,如果發(fā)生擄扣,必須下打撈工具進行打撈。column shedding is a common phenomenon of free tube structure, which is due to the direction of rotation of the friction torque generated by the stator rotor during normal operation is actually a stator&tubing connection1 screw shackle direction, if the friction torque is greater than the pipe le on torque, oil pipe tripping. when the tail pipe is very heavy, there will also be a thread caption. when the pipe column falls off, the production can be restored by reconnecting the work. if the le is not threaded, it can be salvaged by the way of the le. if the le occurs, the fishing tool must be salvaged. 單螺桿泵有以下優(yōu)點: 1)因為泵內(nèi)的回轉(zhuǎn)部件慣性力較低,故可使用-的轉(zhuǎn)速; 2)結(jié)構(gòu)堅實,安裝保養(yǎng)容易; 3)單螺桿泵的壓力和流量范圍寬闊。壓力約在3.4-340千克力/cm2,流量可達18600cm3/分; 4)單螺桿泵的吸入性能好,具有自吸能力; 5)與其它回轉(zhuǎn)泵相比,對進入的氣體和污物不太敏感; 6)流量均勻連續(xù),振動小,噪音低; 7)單螺桿泵的運送液體的種類和粘度范圍寬廣。 單螺桿泵的缺點是,螺桿的加工和裝配要求較高;泵的性能對液體的粘度變化比較敏感。 管柱脫落的故障現(xiàn)象是:運行電流很低,基本上是電機的空載電流,除了有一股一股的氣外,井口基本上無產(chǎn)液,正發(fā)循環(huán)時油套連通。the failure phenomenon of the string is: the running current is very low, basically the motors no load current. besides the gas with a single strand of gas, the wellhead basically has no liquid production,&the oil sleeve is connected when circulating.減少管柱脫落的措施有:將油管上扣扭矩由原來的值提高到值;采用油管螺紋墊片;定子上的裝卸短節(jié)采用防松螺紋連接;采用油管錨或張力封隔器固定螺桿泵。the measures to reduce the falling off of the pipe string are as follows: increase the torque from the original value to the maximum value; use the oil pipe screw gasket; the loading&unloading joint on the stator is connected by loosening screw thread;&use the oil pipe anchor/tension packer to fix the screw pump. 莫諾-螺耐斯設備公司(圖)由武漢螺耐斯設備有限公司提供。莫諾-螺耐斯設備公司(圖)是武漢螺耐斯設備有限公司升級推出的,以上圖片和信息僅供參考,如了解詳情,請您撥打本頁面或圖片上的聯(lián)系電話,業(yè)務聯(lián)系人:余經(jīng)理。
