宜興(xing)打，宜興(xing)承接(jie)10至100米水(shui)(shui)井，宜興(xing)機器打水(shui)(shui)井

射(she)(she)孔(kong)(kong)完(wan)井(jing)(jing)：是指鉆穿油(you)氣層(ceng)(ceng)，將(jiang)油(you)層(ceng)(ceng)套管(guan)下(xia)過油(you)氣層(ceng)(ceng)底部，固(gu)井(jing)(jing)封隔油(you)氣層(ceng)(ceng)，再用射(she)(she)孔(kong)(kong)器射(she)(she)穿油(you)氣層(ceng)(ceng)井(jing)(jing)段的(de)套管(guan)與水泥(ni)環，以形(xing)成油(you)氣流入井(jing)(jing)內(nei)通道的(de)完(wan)井(jing)(jing)。貫(guan)眼完(wan)井(jing)(jing)：是鉆穿油(you)氣層(ceng)(ceng)后將(jiang)帶(dai)孔(kong)(kong)眼（或割縫）套管(guan)下(xia)至油(you)氣層(ceng)(ceng)底部，油(you)氣層(ceng)(ceng)以上井(jing)(jing)眼注水泥(ni)封隔的(de)完(wan)井(jing)(jing)。襯管(guan)完(wan)井(jing)(jing)：是鉆至油(you)氣層(ceng)(ceng)頂部、下(xia)油(you)層(ceng)(ceng)套管(guan)，注水泥(ni)封隔，再用小鉆頭鉆穿油(you)氣層(ceng)(ceng)，下(xia)入帶(dai)孔(kong)(kong)眼（或割縫）的(de)襯管(guan)的(de)完(wan)井(jing)(jing)。

在井(jing)(jing)內泥(ni)漿液柱壓(ya)(ya)(ya)力和地(di)層孔隙壓(ya)(ya)(ya)力近似(si)平衡的條件下進行鉆(zhan)井(jing)(jing)，稱平衡壓(ya)(ya)(ya)力鉆(zhan)井(jing)(jing)。可顯著鉆(zhan)速(su)，也有利(li)于發現(xian)油、氣(qi)藏。 　井(jing)(jing)控(kong)技(ji)術當鉆(zhan)達異常高壓(ya)(ya)(ya)地(di)層而發生泥(ni)漿氣(qi)侵(qin)或井(jing)(jing)涌時，用(yong)計算和恰當的技(ji)術措施，泥(ni)漿比(bi)重和流動(dong)特性(xing)，配合使用(yong)液動(dong)高壓(ya)(ya)(ya)防噴設備進行控(kong)制和排除井(jing)(jing)內溢流，以防止井(jing)(jing)噴。

為防止井(jing)(jing)(jing)(jing)(jing)斜(xie)角和井(jing)(jing)(jing)(jing)(jing)眼曲率過大(da)，選用(yong)合理的下部鉆具。水(shui)(shui)(shui)井(jing)(jing)(jing)(jing)(jing)自古就有，而且它一直為人們供給水(shui)(shui)(shui)資(zi)源，并為農田灌溉做出(chu)了突(tu)出(chu)的貢獻(xian)，發(fa)展到(dao)現在，井(jing)(jing)(jing)(jing)(jing)也已經(jing)有了很大(da)發(fa)展，現在有空調井(jing)(jing)(jing)(jing)(jing)、樁(zhuang)基工程井(jing)(jing)(jing)(jing)(jing)等(deng)多(duo)種(zhong)類型的井(jing)(jing)(jing)(jing)(jing)。洗井(jing)(jing)(jing)(jing)(jing)根(gen)據GB50296-994.6的要求洗井(jing)(jing)(jing)(jing)(jing)及時，洗井(jing)(jing)(jing)(jing)(jing)后進行(xing)抽(chou)水(shui)(shui)(shui)試(shi)(shi)驗(yan)(yan)，確定(ding)該(gai)(gai)井(jing)(jing)(jing)(jing)(jing)量(liang)(liang)、含(han)沙(sha)量(liang)(liang)，該(gai)(gai)井(jing)(jing)(jing)(jing)(jing)采(cai)用(yong)拉孔和空壓(ya)機反沖(chong)、正掏聯(lian)合洗井(jing)(jing)(jing)(jing)(jing)法，已達到(dao)量(liang)(liang)和含(han)沙(sha)量(liang)(liang)的要求，抽(chou)水(shui)(shui)(shui)試(shi)(shi)驗(yan)(yan)后期取水(shui)(shui)(shui)樣進行(xing)水(shui)(shui)(shui)質(zhi)分析(xi)。
