近日，中(zhong)國石化重點探井(jing)馬深1井(jing)順(shun)利完(wan)鉆(zhan)，完(wan)鉆(zhan)井(jing)深8418米，創亞洲第(di)一超深鉆(zhan)井(jing)紀錄(lu)。
馬深(shen)(shen)1井(jing)(jing)的成功鉆(zhan)探(tan)(tan)，進(jin)一(yi)步豐富(fu)完善了(le)超深(shen)(shen)井(jing)(jing)鉆(zhan)井(jing)(jing)綜合配套技(ji)(ji)術，為國內(nei)超深(shen)(shen)井(jing)(jing)鉆(zhan)探(tan)(tan)積(ji)累寶貴經(jing)驗(yan)，標志著中(zhong)國石化(hua)超深(shen)(shen)井(jing)(jing)鉆(zhan)井(jing)(jing)工程技(ji)(ji)術跨入世界領(ling)先(xian)技(ji)(ji)術行列。
馬深1井是中(zhong)國(guo)石化部署(shu)在四川盆地(di)川東北(bei)地(di)區的一(yi)口(kou)重點(dian)探井，井位(wei)所(suo)處構造帶地(di)質狀況復雜(za)，需要分別(bie)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)遇陸相地(di)層、海相地(di)層，難度國(guo)內罕見。該井由石化油服(fu)所(suo)屬中(zhong)原石油工程公司90106ZY鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)井隊(dui)承鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)，鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)井過程中(zhong)創(chuang)出一(yi)系列(lie)高(gao)指標和新(xin)(xin)紀(ji)錄。一(yi)是在陸相地(di)層積極(ji)推廣應用泡沫鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)井、“高(gao)速(su)渦輪(lun)+孕鑲金剛石鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)”“低(di)速(su)大(da)扭矩螺桿(gan)+高(gao)效(xiao)PDC鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)”等新(xin)(xin)技術，機械鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)速(su)平均(jun)提高(gao)64%；二(er)是在下部海相地(di)層，采用旋沖(chong)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)井和高(gao)效(xiao)螺桿(gan)復合鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)井技術，機械鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)速(su)較常規牙輪(lun)鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)提高(gao)近3倍,并創(chuang)下單只鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)頭(tou)最高(gao)進尺和最高(gao)機械鉆(zhan)(zhan)(zhan)(zhan)(zhan)(zhan)速(su)。
