近日，中(zhong)國石化(hua)重點探(tan)井(jing)馬(ma)深1井(jing)順(shun)利完(wan)鉆(zhan)(zhan)(zhan)，完(wan)鉆(zhan)(zhan)(zhan)井(jing)深8418米，創亞洲第一超深鉆(zhan)(zhan)(zhan)井(jing)紀錄。
馬深1井(jing)(jing)的成功鉆探，進一步豐富完善了超(chao)深井(jing)(jing)鉆井(jing)(jing)綜合配套技術，為國內(nei)超(chao)深井(jing)(jing)鉆探積累寶貴經驗，標志著中(zhong)國石(shi)化超(chao)深井(jing)(jing)鉆井(jing)(jing)工程技術跨入世(shi)界領先技術行列。
馬深1井(jing)(jing)是中(zhong)(zhong)國石(shi)化(hua)部署在(zai)四川(chuan)(chuan)盆地(di)川(chuan)(chuan)東北地(di)區的一(yi)(yi)口(kou)重點(dian)探井(jing)(jing)，井(jing)(jing)位所處(chu)構(gou)造帶地(di)質狀況復(fu)雜，需要分別(bie)鉆(zhan)(zhan)(zhan)(zhan)遇陸(lu)相(xiang)地(di)層(ceng)、海相(xiang)地(di)層(ceng)，難度國內罕見。該井(jing)(jing)由石(shi)化(hua)油服(fu)所屬中(zhong)(zhong)原石(shi)油工程公(gong)司90106ZY鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)隊承鉆(zhan)(zhan)(zhan)(zhan)，鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)過程中(zhong)(zhong)創(chuang)出(chu)一(yi)(yi)系列高(gao)(gao)指標和新紀錄。一(yi)(yi)是在(zai)陸(lu)相(xiang)地(di)層(ceng)積(ji)極推(tui)廣應(ying)用泡沫鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)、“高(gao)(gao)速(su)(su)渦輪(lun)+孕鑲(xiang)金剛石(shi)鉆(zhan)(zhan)(zhan)(zhan)頭”“低速(su)(su)大扭矩(ju)螺桿(gan)+高(gao)(gao)效PDC鉆(zhan)(zhan)(zhan)(zhan)頭”等新技(ji)術，機(ji)(ji)械鉆(zhan)(zhan)(zhan)(zhan)速(su)(su)平均(jun)提高(gao)(gao)64%；二(er)是在(zai)下(xia)部海相(xiang)地(di)層(ceng)，采用旋沖鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)和高(gao)(gao)效螺桿(gan)復(fu)合鉆(zhan)(zhan)(zhan)(zhan)井(jing)(jing)技(ji)術，機(ji)(ji)械鉆(zhan)(zhan)(zhan)(zhan)速(su)(su)較常規牙(ya)輪(lun)鉆(zhan)(zhan)(zhan)(zhan)頭提高(gao)(gao)近3倍,并(bing)創(chuang)下(xia)單(dan)只鉆(zhan)(zhan)(zhan)(zhan)頭最高(gao)(gao)進尺和最高(gao)(gao)機(ji)(ji)械鉆(zhan)(zhan)(zhan)(zhan)速(su)(su)。
