Conoco公司在北海英国与荷兰所属海域范围内,钻成了两口水平井,并取得测试结果。Conoco公司与英国合作,在北海North Valiant气田钻成英国第一口水平井——Dunchunter井,该井采用中曲率半径钻井工艺技术,垂直井深(TVD)2470米,测量总深度为3353米,在Rotliegendes砂岩层中水平井段为607米。井眼斜度,平均造斜率39.4°/100米,是常规定向斜井的5倍。完钻成本比该地区常规井高35％,但稳定气产量提高3倍,原始产气量就更高。 Conoco公司与荷兰合作,在荷兰的Kotter油田同样采用中曲率半径钻井工艺技术,完钻的K8/1A井,该井是以一口报废的生产油井开窗侧钻成功的一口水平井,测量总深度为
Conoco drilled two horizontal wells over the North Sea and the Dutch maritime area and obtained the test results. Conoco, in partnership with the United Kingdom, drilled the UK’s first horizontal well, the Dunchunter, in the North Valiant gas field in the North Sea. The well uses a medium radius of curvature drilling technique with a vertical depth of TV (TVD) of 2470 meters and a total survey depth of 3353 meters. The horizontal section of the Rotliegendes sandstone is 607 meters. Wellbore slope, the average slope of 39.4 ° / 100 meters, is 5 times the conventional directional incline. The cost of drilling is 35% higher than conventional wells in the region, but the stable gas production is tripled and the original gas production is even higher. Conoco, in cooperation with the Netherlands, also drilled a K8 / 1A well drilled in the Kotter field in the Netherlands using a medium radius of curvature drilling technique. The well is a horizontal well that has been successfully drilled in a scrapped production well and has measured total depth for
