沙参2井于1984年9月22日凌晨4时发生强烈井喷,为塔里木盆地东北坳陷石油普查勘探揭示了光明前景。本井于3876—3892米井段(中新统吉迪克组)发现油气显示,测井解释为可能含油层。据测井资料,在侏罗系中也可能有油气存在。井深5391.18米提钻过程中发生井喷,出油井段应在5335.76米(7英寸尾管深度)与5391.18米之间。由于泥浆比重达1.23时仍漏失20余立方米,估算井底压力应小于663大气压。根据 K-83-05线、TB-80-302线、K-82-92线地震资料,可知在沙参2井附近,海
Shashen 2 well developed a strong blowout at 4:00 on September 22, 1984, revealing a bright prospect for oil census exploration in the northeastern depression of the Tarim Basin. Wells in the 3876-3892 m interval (Miocene Kitidic) found that oil and gas logging, log interpretation may be oil-bearing. According to well logging data, there may be oil and gas in the Jurassic. Well depth 5391.18m Blowout occurred during withdrawal, the outlet section should be 5335.76 meters (7 inches tail pipe depth) and 5391.18 meters. As the proportion of mud reached 1.23 still lost more than 20 cubic meters, the bottom hole pressure should be estimated less than 663 atmospheres. According to the K-83-05 line, TB-80-302 line and K-82-92 line seismic data, we can see that near the Shashen 2 well, the sea
