由四川石油管理局和成都无缝钢管厂联合试制的CS—90SS高强度、抗硫化氢腐蚀φ178套管。于1992年3月30日在川东钻探公司铁山6井顺利下井,一次性注水泥固井成功。铁山6井φ244套管下至井深2233.73m。1992年3月19日用φ216钻头钻至井深4025m,层位:石炭系顶部。裸眼长1791.27m,全井最大井斜角11°(并深2800m处),泥浆密度1.67g/cm~3。钻进中先后在Tf~(3 1)、P_2~2、P_1~3_1层发现气显示,其中P_2~2中测,产气1.85万m~3/d。在全队职工及现场工程技术人员的共
CS-90SS high-strength, hydrogen sulfide corrosion-resistant φ178 bushing jointly piloted by Sichuan Petroleum Administration and Chengdu Seamless Steel Tube Works. On March 30, 1992, the company successfully went down well in the Tieshan 6 well of the drilling company in eastern Sichuan Province and succeeded in cementing and cementing once. Tieshan 6 wells φ244 casing down to the depth of 2233.73m. March 19, 1992 with φ216 drill to the well depth 4025m, horizon: the top of the Carboniferous. The unaided eye length is 1791.27m, the full well inclination is 11 ° (depth 2800m) and mud density is 1.67g / cm ~ 3. During the drilling, gas was found in Tf ~ (3 1), P_2 ~ 2 and P_1 ~ 3_1 layers, of which P 2 ~ 2 was measured and gas production was 18,500 m 3 / d. In the entire team of workers and field engineering and technical personnel of the total
