使其滿足鉆井(jing)(jing)(jing)(jing)要求。操作要求。這個過程叫(jiao)做(zuo)洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)。洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)是(shi)抽(chou)水(shui)試驗(yan)前(qian)的(de)一個必要階段。泥(ni)漿更換、洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)和(he)泵(beng)(beng)送是(shi)三種連(lian)續作業。洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)方法包括：用(yong)(yong)原鉆井(jing)(jing)(jing)(jing)泵(beng)(beng)向井(jing)(jing)(jing)(jing)內泵(beng)(beng)入(ru)清(qing)水(shui)，即(ji)用(yong)(yong)泥(ni)漿代(dai)替淡(dan)水(shui)后，繼續循環洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)，稱為(wei)清(qing)水(shui)洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing);停(ting)止清(qing)水(shui)循環，繼續提升(sheng)上下(xia)移動井(jing)(jing)(jing)(jing)管，產生壓力激勵(li)，破壞(huai)井(jing)(jing)(jing)(jing)壁泥(ni)皮(pi)，疏通含水(shui)層(ceng)孔隙，稱為(wei)沖洗(xi)(xi)(xi)，沖洗(xi)(xi)(xi)需交替反復進入(ru)井(jing)(jing)(jing)(jing)內。抽(chou)水(shui)試驗(yan)前(qian)，采用(yong)(yong)離心泵(beng)(beng)或壓縮(suo)空氣機抽(chou)取地(di)(di)下(xia)水(shui)，達(da)到水(shui)的(de)清(qing)潔度和(he)的(de)流(liu)出量，抽(chou)水(shui)試驗(yan)稱為(wei)泵(beng)(beng)吸(xi)洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)和(he)壓縮(suo)空氣洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)。此外(wai)，還采用(yong)(yong)了(le)二氧化碳洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)和(he)酸性洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)。以上內容由(you)洗(xi)(xi)(xi)井(jing)(jing)(jing)(jing)小編整理(li)，本(ben)文觀(guan)點不代(dai)表(biao)本(ben)站觀(guan)點。2.注意地(di)(di)面排(pai)水(shui)。地(di)(di)下(xia)水(shui)靠近地(di)(di)面，經(jing)常，排(pai)水(shui)。3.到處都是(shi)干旱。中間只有一個的(de)地(di)(di)方，那(nei)里的(de)作物(wu)很晚(wan)才。
