据悉 ,迪那 2井是位于新疆塔里木油田库车山前迪那 2号构造上的一口探井。该井于 2 0 0 0 - 0 8- 0 5开钻 ,钻井技术难度大 ,风险高。于 2 0 0 1 - 0 4 - 2 9钻至井深为 4875 m时 ,钻遇高压气层 ,地层压力高达1 0 0多 MPa。经科技攻关后 ,才解决了膏盐层、井壁垮塌、井漏严重、
It is reported that Dina 2 well is located in Tarim Oilfield in Xinjiang Kuqa Hill front Dina structure on a exploration well. The well was drilled from 2000-0805, drilling technology is difficult and risky. When drilling at a depth of 4875 m between 20 001 and 04 2 9, a high pressure gas reservoir was drilled and the formation pressure was as high as more than 1 000 MPa. After scientific and technological tackles, it solved the gypsum salt, wall collapse, serious well leakage,
