胜利油田测井公司研究所研制的SLQ89—1型井壁取心器近日在渤深5井、桩古13—2井和渤深4井等超深井井壁取心试用一次成功,取心深度实破5400m大关。它标志着胜利油田井壁取心技术又上了一个台阶。渤深5井,取心器下放深度为5455.93m,取得最深位置的岩心深度是5426.8m。井内压力为74MPa、地层温度为191℃、取心井段属砂泥岩剖面。结果:点火31颗,发射26颗,取得20颗岩心,发射率为84%,收获率为77%。桩古13—2井,井深为5083m,取得
The Shengli Oilfield Logging Company Institute developed the SLQ89-1 wellbore take-up device recently successfully performed well-coring tests on wellbores such as Bo-Shen 5 well, Pangu 13-2 well and Bo-Shen 4 well, and coring depth Broke 5400m broken mark. It marks Shengli Oilfield shaft wall coring technology to a higher level. Well Bo 1 deep well 5, divertorial depth of 5455.93m, to obtain the deepest position of the core depth is 5426.8m. Well pressure was 74MPa, formation temperature of 191 ℃, coring section of sand and shale profile. Results: 31 fires, 26 shots, 20 cores, an emissivity of 84% and a yield of 77%. Pile ancient 13-2 well depth of 5083m, made
