辽河油田开采的稠油油田有高升油田、曙一区及欢17块,日产原油1918吨.7英寸套管的蒸汽吞吐工艺已初步配套,井筒隔热管柱、高温封隔器和热采井口装置基本达到工艺技术要求,可以配套生产;现已能较好地完成1600米井深、高压、低干度和1000米井深、较高干度的吞吐工作.稠油井经蒸汽吞吐后产量普遍增加(初期日产一般都在20
The heavy oil fields exploited by Liaohe Oilfield are Gaosheng Oilfield, Shuyi District and Huanhuan Block, with 1918 tons of Nissan crude oil. The steam huff and puff process of 7-inch casing has been initially matched with wellbore thermal insulation columns, high-temperature packer and thermal wellhead The device basically meets the technical requirements and can be used for production. Now it can well complete the throughput work of 1,600 meters of well depth, high pressure, low dryness and 1,000 meters of well depth and higher dryness. The output of heavy oil wells generally increases after steam huff and puff The initial Nissan are generally 20
