得克萨斯蒙屯东北的斯拉士兰奇油田上钻了2口相邻的生产井。第一口于1975年3月完成,用了144天时间,24只钻头,井深6599米。第二口井于1975年10月17日开钻,1976年2月22日钻达6644.8米,用了129天时间,16只钻头。第二口井打得好,主要是吸取了第一口井成功的经验,包括良好的准备计划、钻井设备、人员、维护保养以及配合协作。钻杆在使用前都经过彻底检查,并采用腐蚀控制措施加以保护。井场管理非常好,准备计划把绝大部可能遇到的问题都预计到了,钻井和泥浆工作人员也都是精干而富有经验的。蒙屯区在特拉华盆地,30多年来对钻深井是个“禁区”。蒙屯的严重困难的钻井问题
Two adjacent production wells were drilled in the Slaskran field north-east of Montenton, Texas. The first port was completed in March 1975, spent 144 days, 24 drill bits, well depth of 6,599 meters. The second well was drilled on October 17, 1975, drilling 6644.8 meters on February 22, 1976, for 129 days and 16 bits. The second well fought well, mainly drawing on the successful experience of the first well, including good preparation plans, drilling equipment, personnel, maintenance and collaboration. Drill rods are thoroughly inspected before use and are protected by corrosion control measures. Well site management is very good, preparation plan to predict most of the problems that may be encountered, drilling and mud workers are lean and experienced. In the Delaware Basin, the Tuen Mun District is a “closed area” for drilling deep wells for more than 30 years. A serious hardship drilling problem in Meng Tun
