川·克6英寸C_2—01型金刚石取心钻头(简称“川克”)与川·石6英寸金刚石取心钻头(简称“川石”)在结构上大致一样,川克与川石的区别在于川克金刚石颗粒较粗而长,成柱状,嵌于胎体上露高约1.5mm,水槽浅一点,内台阶改为用扶正块。 1990年2月22日用川克钻头在池20井开始取心。地层:石嵌系;岩性:白云岩;取心深度:3068.86m,泥浆密度1.41g/cm~3。使用钻压40KN,转速60r/min,排量81/s,泵压9MPa。纯钻15:00,进尺10.20m,机械钻速0.68m/h。钻速较慢认为是卡心。起钻检
Chuanke grams 6 inches C_2-01 diamond coring bit (referred to as “Chuanke”) and Chuan Stone 6-inch diamond coring bit (referred to as “Chuan Shi”) in the structure is roughly the same, Chuanke and Chuanshi difference is that Chuan Grained diamond particles thick and long, into a columnar, embedded in the carcass on the exposed high about 1.5mm, shallow sink, the steps to the right to use correction block. February 22, 1990 Chuan Ke drilling bit in the pool 20 began to coring. Stratum: Stone embedded system; Lithology: dolomite; Coring depth: 3068.86m, mud density 1.41g / cm ~ 3. Use the weight-40KN, speed 60r / min, displacement 81 / s, pump pressure 9MPa. Pure diamond 15:00, into the ruler 10.20m, penetration rate 0.68m / h. Slow drilling speed is considered card center.
