鉆(zhan)井泥漿(jiang)當屬膨(peng)潤土產業的第二大用戶了,每年的膨(peng)潤土用量(liang)至少60~70萬噸。
膨潤(run)(run)土(tu)(tu)是(shi)一種(zhong)理想的(de)低固(gu)相鉆(zhan)(zhan)井(jing)(jing)造(zao)漿材料,遇(yu)水后具(ju)有較好的(de)潤(run)(run)滑(hua)(hua)性(xing)、懸浮性(xing)、粘(zhan)結性(xing)、膨脹性(xing)。我(wo)們按照一定比例(li)將膨潤(run)(run)土(tu)(tu)與水充(chong)分溶(rong)解后可以(yi)發(fa)現膨潤(run)(run)土(tu)(tu)可以(yi)呈現出高粘(zhan)度(du)的(de)懸浮狀凝膠溶(rong)液,這(zhe)類凝膠溶(rong)液具(ju)有較好的(de)造(zao)漿性(xing)、粘(zhan)結性(xing)、潤(run)(run)滑(hua)(hua)性(xing)以(yi)及(ji)懸浮性(xing)和觸變(bian)性(xing)。膨潤(run)(run)土(tu)(tu)在鉆(zhan)(zhan)井(jing)(jing)泥(ni)漿中的(de)主要作用(yong)是(shi):冷卻鉆(zhan)(zhan)頭、潤(run)(run)滑(hua)(hua)鉆(zhan)(zhan)桿、上返(fan)巖(yan)屑、保(bao)護井(jing)(jing)壁、平衡地層壓(ya)力。當鉆(zhan)(zhan)井(jing)(jing)遇(yu)到各(ge)類復(fu)雜的(de)地質(zhi)(zhi)層時極易(yi)出現井(jing)(jing)壁塌陷(xian)、掉塊(kuai)、埋鉆(zhan)(zhan)等事故,這(zhe)時候(hou)必須(xu)使(shi)用(yong)優(you)質(zhi)(zhi)鈉(na)基膨潤(run)(run)土(tu)(tu)進行泥(ni)漿護壁,防止各(ge)類塌孔、埋鉆(zhan)(zhan)事故的(de)發(fa)生,減少損失,提高鉆(zhan)(zhan)井(jing)(jing)效(xiao)率。
我公司膨潤土在鉆井(jing)泥漿(jiang)方面的應用廣(guang)泛,目前長春地鐵5號線(xian)(xian)(xian)(xian)一(yi)(yi)期(qi)、6號線(xian)(xian)(xian)(xian);7號線(xian)(xian)(xian)(xian)一(yi)(yi)期(qi)、9號線(xian)(xian)(xian)(xian)一(yi)(yi)期(qi);4號線(xian)(xian)(xian)(xian)南(nan)延(yan)(yan)、2號線(xian)(xian)(xian)(xian)東(dong)延(yan)(yan)主(zhu)體;2號線(xian)(xian)(xian)(xian)東(dong)東(dong)延(yan)(yan)、3號線(xian)(xian)(xian)(xian)南(nan)延(yan)(yan),1號線(xian)(xian)(xian)(xian)南(nan)延(yan)(yan),都在建設中(zhong),雖(sui)然供貨一(yi)(yi)部(bu)分,但(dan)是市場占有(you)率還是遠遠不(bu)夠(gou),地鐵的盾構應用還要(yao)大力(li)開發(fa)。
