泥饼粘附卡钻在钻中深井及深井过程中是极易发生的事故。钻具在井内停留稍久,往往酿成泥饼粘附卡钻事故。近年来我局泥浆工作在这方面摸索了不少新方法。川西北矿区、川中矿区、川东钻探公司采用固体粉状解卡剂 SR—301和油基泥浆解卡液,均收到满意的效果。川中的台4井1984年5月用钢丝打捞筒打捞牙轮后,起钻至离井底10.25m 接单根配立柱时发生了卡钻,卡点约在1600～1750m井段,最初采用8m~3柴油浸泡无效,便用粉状解卡剂 SR—301,浸泡卡点32小时29分钟,使被禁锢在
Mud cake sticking stuck drill in the deep and deep well process is extremely prone to accidents. Drilling stays in the well for a long time, often resulting in mud cake stuck stuck accident. In recent years, our bureau mud work in this area to explore a lot of new ways. Sichuan Northwest Mining Area, Sichuan Central Mining Area, East Sichuan Drilling Company using solid powdered anti-card agent SR-301 and oil-based mud solution, have received satisfactory results. After drilling the cone with a steel overshot in May 1984, a stuck drill occurred when drilling a single root with 10.25m from the bottom of the well. The stuck point was about 1600-1750m. The initial interval was 8m ~ 3 diesel immersion is invalid, they use powder card-dissolving agent SR-301, soak the card point for 32 hours and 29 minutes, so be imprisoned
