Lub hom phiaj ntawm lub zog qis ntawm cov roj-raws li drilling kua, uas tuaj yeem yooj yim ua rau muaj teeb meem loj xws li xuab zeb sinking thiab yeeb nkab sticking, Lub Tsev Kawm Qib Siab Petroleum Engineering ntawm Yangtze University tau tsim cov polyether fatty acid roj-raws li drilling kua Gel Modifier LQZ.
Siv infrared spectroscopy, thermo-gravimetric nkhaus, gel lub zog thiab interfacing expansion rheological tsis, thiab lwm yam., cov qauv, thermal stability, gel kev ua tau zoo thiab mechanism ntawm kev txiav txim ntawm tus neeg sawv cev shearing tau soj ntsuam, thiab lub hauv paus roj, roj-dej piv, ceev thiab cov nyhuv ntawm qhov kub thiab txias ntawm nws cov nyhuv lifting. Cov txiaj ntsig tau pom tias cov molecule ntawm Gel Modifier muaj cov pab pawg hydroxyl, amide pawg, ester pawg thiab ether daim ntawv cog lus, uas tuaj yeem tsim cov qauv hauv network, txhim kho lub peev xwm ncua kev kawm, thiab muaj cov yam ntxwv ntawm kev ceev thiab tsis muaj zog gelation; tsis muaj qhov pom tseeb thermal decomposition ntawm 300 degree ; cov nyiaj ntxiv yog tsawg dua 0.85 feem pua yog qhov zoo rau kev ruaj ntseg ntawm emulsion; Gel Modifier feem ntau siv tau rau cov roj dawb-raws li, diesel-based thiab hluavtaws-based drilling kua tshuab, thiab cov nyhuv yog qhov zoo tshaj plaws hauv cov roj dawb; Thaum cov roj-dej piv ntawm cov kua dej drilling yog 8: 2 thiab qhov ceev yog 2.1 g / cm3, 190 degree, Gel Modifying efficiency yog qhov zoo tshaj plaws, thiab dynamic shearing quab yuam, φ6 thiab φ3 nyeem thiab zoo li qub shearing quab yuam nce los ntawm txog 1 zaug; piv nrog cov khoom txawv teb chaws zoo sib xws, LQZ muaj qhov zoo ntawm kev ua kom cov viscosity tsis muaj plasticizing.
Thaum LQZ siv rau hauv shale roj thiab roj qhov dej, qhov dynamic shear quab yuam, φ6 thiab φ3 nyeem ntawv thiab static shear force pib nce 100 feem pua, thiab cov yas viscosity tsis nce ntau. LQZ tuaj yeem txhim kho lub peev xwm ncua ntawm cov roj-raws li cov dej drilling yam tsis muaj qhov ua kom cov yas viscosity, yog li nws muaj kev cia siab zoo rau kev nyiam thiab kev siv.
