1. Dab tsi yog lub twj tso kua dej?
A Puv Stroke Txeeyog ib qho cuab yeej siv los ntsuas thiab sau cov reciprocating taw ntawm lub twj tso dej khov lub piston. Nws yog ib txwm ntsia rau ntawm lub twj tso drilling lossis cuam tshuam nrog cov kab ke hydraulic. Los ntawm sensors lossis cov txheej txheem zoo sib xws, nws saib xyuas cov twj tso dej num hauv lub sijhawm thiab hloov tshuab rau hauv lub sijhawm thiab hloov tshuab qhia cov khoom siv tawm mus rau lub twj tso kua dej stroke. Nws cov ntsiab cai ua haujlwm feem ntau cia siab rau kev siv tshuab, hluav taws xob, lossis cov txheej txheem hydraulic. For example, mechanical counters connect to the pump's moving components and use gear transmission mechanisms to record strokes, while electronic counters detect electrical signals or magnetic field changes generated by the pump's motion for counting.
2. Lub luag haujlwm hauv kev tswj tau zoo
Qhov tseeb kev ntsuas ntawm Drilling cov kua dej tsis haum Los ntawm kev sib txuas ua ke cov twj tso kua mis suav los ntawm cov twj tso kua mis kaw nrog cov twj tso kua mis uas muaj qhov ntev thiab linplacement tus nqi ntawm cov kua dej yuav muaj peev xwm suav tau meej. Qhov no pab tswj cov neeg ua haujlwm saib xyuas cov neeg ua haujlwm hauv dej hauv dej hauv dej.
Kev soj ntsuam downhole siab hloov: lub twj tso kua mis stroke cov ntaub ntawv raug khi tau raug khi ze rau hauv qab siab. Kev tswj hwm kev mob stroke ruaj khov thaum lub sijhawm xyaum ua kom ruaj khov ua kom nruj ib ce zoo ib ntus. Thaum muaj kev sib tw khiav lossis ploj ncig, hloov pauv hauv tus nqi stroke muaj cov cim tam sim ntawd. Piv txwv li, yog tias tus nqi stroke tas mus li tab sis cov kua dej ua kom muaj cov kua dej rov qab, nws tuaj yeem qhia txog qhov tsis zoo, qhia tias muaj kev tswj hwm kho tau yooj yim.
Pab nyob rau hauv kev tua cov haujlwm tau zoo: zoo tua, ib tug tseem ceeb tswj kev tswjhwm zoo, xav tau kev tswj cov kua dej drilling thiab siab. Lub twj tso cua nyob sab nrauv muab cov kev tawm tsam muaj tseeb, ua rau cov neeg ua haujlwm muaj tseeb, ua rau cov neeg ua haujlwm raug tshem tawm cov khoom npaj tua tau raws li cov phiaj xwm ua ntej. Qhov no yuav pab maj mam rov kho cov dej qis qis qis sib npaug, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo tua.
Cov ntaub ntawv txhawb rau kev tswj hwm cov kev txiav txim siab tau zoo: txuas ntxiv sau tseg stroke suav cov ntaub ntawv cov ntaub ntawv kab nkhaus. Los ntawm kev txheeb xyuas cov curves, cov neeg ua haujlwm tswj tau zoo tuaj yeem txheeb xyuas cov ncauj lus hauv kev ua haujlwm, xws li mob stroke tus nqi lossis kev sib txawv. Cov ntaub ntawv-tsav insrivs txhawb kev txiav txim siab txiav txim siab, cia cov kev hloov kho kom muaj sijhawm kom daws cov haujlwm drooreguard drilling.
