Oilwell cementing additive cenosphere
Cenospheresmuaj ntau daim ntawv thov hauv kev lag luam oilfield vim lawv cov khoom tshwj xeeb.
Nov yog qee qhov ntawm lawv siv:
1.Drilling kua : Cenospheres tuaj yeem muab ntxiv rau cov dej drilling los txhim kho lawv cov kev ua tau zoo. Lawv txhim kho cov kua dej ntom ntom, nce lubricity, thiab txo qhov hnyav tag nrho ntawm cov kua dej drilling. Qhov no pab tswj lub siab exerted ntawm qhov tsim tau drilled thiab tiv thaiv blowouts.
2.Cement Slurries : Cenospheres yog siv hauv cov roj zoo cement slurries los txhim kho lawv cov khoom. Los ntawm kev sib koom ua ke ntawm cenospheres rau hauv cov cement formulations, slurry ceev yuav txo tau yam tsis muaj kev cuam tshuam nws lub zog. Qhov no yuav pab tiv thaiv kom tsis txhob muaj siab dhau ntawm lub qhov dej thiab txo qhov kev pheej hmoo ntawm kev tsim kev puas tsuaj.
3.Cov khoom siv rwb thaiv tsev : Cenospheres yog siv rau hauv kev tsim cov khoom siv hluav taws xob sib sib zog nqus siv hauv cov roj thiab cov kav dej thiab cov khoom siv. Lub hollow xwm ntawm cenospheres muab zoo heev thermal rwb thaiv tsev, txo tshav kub hloov thiab txhim kho zog efficiency nyob rau hauv oilfield ua hauj lwm.
4.Proppants : Cenospheres tuaj yeem coated nrog resins lossis lwm yam khoom siv thiab siv los ua cov khoom siv hauv hydraulic fracturing. Cov khoom siv hnyav no pab tswj cov pob txha pob txha qhib thiab tso cai rau cov roj ntws los yog cov pa roj thaum txo qhov hnyav tag nrho thiab qhov ntom ntawm cov pob khoom.
5.Vaj tse thiab Enclosures : Cenospheres tuaj yeem muab tso rau hauv cov khoom siv sib xyaw siv los tsim cov khoom siv roj av, xws li vaj tse thiab cov ntaub thaiv npog. Qhov sib ntxiv ntawm cenospheres txhim kho lub zog-rau-qhov hnyav piv ntawm cov khoom sib xyaw, ua rau lawv muaj zog dua thiab hnav.
Cov no tsuas yog qee qhov piv txwv ntawm kev siv cenospheres li cas hauv kev lag luam oilfield. Lawv lub teeb yuag, thermal rwb thaiv tsev, thiab cov khoom muab tub lim ua rau lawv cov khoom tseem ceeb hauv ntau yam kev ua haujlwm thiab cov ntaub ntawv.
