　　成(cheng)(cheng)井(jing)工(gong)(gong)藝1、下(xia)(xia)井(jing)管(guan)(guan)(guan)(guan)前，應對鉆(zhan)孔(kong)(kong)孔(kong)(kong)壁，孔(kong)(kong)徑(jing)(jing)、孔(kong)(kong)深(shen)(shen)進行(xing)校核，查(cha)明孔(kong)(kong)壁是否規(gui)則圓滑，發現有(you)縮徑(jing)(jing)等(deng)不規(gui)則孔(kong)(kong)壁時(shi)(shi)(shi)及(ji)時(shi)(shi)(shi)修整(zheng)，以(yi)后(hou)續工(gong)(gong)序的順利實施，并(bing)實測孔(kong)(kong)深(shen)(shen)。2、換(huan)漿(jiang)(jiang)。用稀(xi)漿(jiang)(jiang)或清(qing)水(shui)孔(kong)(kong)底，自下(xia)(xia)而上將原成(cheng)(cheng)孔(kong)(kong)時(shi)(shi)(shi)的濃漿(jiang)(jiang)換(huan)出孔(kong)(kong)。當(dang)井(jing)內返上泥漿(jiang)(jiang)與的稀(xi)漿(jiang)(jiang)水(shui)的濃度基本相同(tong)時(shi)(shi)(shi)，換(huan)漿(jiang)(jiang)即已(yi)完成(cheng)(cheng)。3、下(xia)(xia)管(guan)(guan)(guan)(guan)。下(xia)(xia)管(guan)(guan)(guan)(guan)按技術要求進行(xing)。要安裝(zhuang)井(jing)管(guan)(guan)(guan)(guan)找中器(qi)，焊(han)工(gong)(gong)作業，并(bing)加(jia)焊(han)2-4塊拉板(ban)，必要時(shi)(shi)(shi)管(guan)(guan)(guan)(guan)內須加(jia)浮板(ban)，管(guan)(guan)(guan)(guan)底用鋼板(ban)焊(han)封。4、填(tian)(tian)礫料。將選好的礫料投入井(jing)管(guan)(guan)(guan)(guan)過(guo)濾器(qi)及(ji)孔(kong)(kong)壁之(zhi)間的環狀空間內。根據(ju)地質技術要求和(he)地層(ceng)(ceng)情況選用靜(jing)止投礫法(fa)，管(guan)(guan)(guan)(guan)外投礫法(fa)，抽(chou)(chou)水(shui)填(tian)(tian)礫法(fa)等(deng)工(gong)(gong)藝。5、止水(shui)。常用為粘(zhan)土(tu)球止水(shui)法(fa)。粘(zhan)土(tu)球，并(bing)分層(ceng)(ceng)填(tian)(tian)入，逐層(ceng)(ceng)填(tian)(tian)滿(man)，填(tian)(tian)實。6、洗(xi)井(jing)。洗(xi)井(jing)的目的是鉆(zhan)井(jing)中孔(kong)(kong)內巖屑(xie)等(deng)對含水(shui)層(ceng)(ceng)的封堵(du)，同(tong)時(shi)(shi)(shi)濾水(shui)管(guan)(guan)(guan)(guan)周圍含水(shui)層(ceng)(ceng)中泥漿(jiang)(jiang)、粉、細砂(sha)等(deng)沉淀，以(yi)含水(shui)層(ceng)(ceng)通暢。7、井(jing)孔(kong)(kong)在驗收前，進行(xing)簡易抽(chou)(chou)水(shui)試(shi)驗，測定(ding)井(jing)的實際可開采水(shui)量，在開泵后(hou)30min取水(shui)樣測量含沙量和(he)進行(xing)水(shui)質分析采樣。而后(hou)編(bian)寫鑿井(jing)工(gong)(gong)程報告。
