HW902稠油水平井是总公司“九五”重点科技项目“浅层稠油水平井开采新技术研究”的第一口科学试验水平井,也是目前国内钻成的第一口浅层大位移水平井(实钻井深493m)与垂深(174.8m)之比为2.82)。该井经过油藏工程、钻井工程、采油工程等多方面的反复研究论证,选取克拉玛依九8区齐古组稠油油藏为斜直井钻机钻水平井实验区进行实验。HW902水平井完钻井深493m,垂深174.8m,井斜90.5°,闭合方位267.37°,水平位移408.4m,各项技术指标达到设计要求,多项技术指标创国内水平井最新记录。
The HW902 heavy oil horizontal well is the first scientific experiment horizontal well of the “Nine Five-Year Plan” key science and technology project of “new technology of shallow heavy oil horizontal well exploration” and also the first shallow horizontal large displacement horizontal well drilled in China Actual drilling depth 493m) and the vertical depth (174.8m) ratio of 2.82). The well is subjected to repeated research and demonstration of various aspects such as reservoir engineering, drilling engineering and oil recovery engineering. The experiment is carried out by selecting the Qigu Formation heavy oil reservoir in Karamay as the inclined well drilling horizontal well. The horizontal drilling well of the HW902 horizontal well has a depth of 493m, a depth of 174.8m, a well inclination of 90.5 °, a closed orientation of 267.37 ° and a horizontal displacement of 408.4m. Various technical indicators have met the design requirements. A number of technical indicators have hit the domestic horizontal well Latest record.
