文章先是阐述火驱技术的应用现状,火驱技术原理、分类及其具有采收率高、应用范围广的优点;高升合作区块块继续吞吐开发指标低,经济效益差,而进行火驱开发操作成本低,数模研究表明提高采收率30-35%,经济效益明显。先导试验现场实施一年半,主要开发指标均超过方案设计指标,井组日产油由驱前的24.7t/d上升到目前的42t/d,但同时也暴露出油藏地质、采油工艺集输及安全环保等方面一系列问题,为下步高升合作区块全面转驱积累了丰富的经验。
The article first elaborates the current situation of the application of fire flooding technology, the principle and classification of fire flooding technology, and has the advantages of high recovery rate and wide application range. The high flooding cooperation block continues to have low throughput and low economic benefit, Low operating costs, numerical simulation studies have shown that the recovery rate of 30-35%, significant economic benefits. Pilot test site for a year and a half, the main development indicators are beyond the program design indicators, well group daily output from the pre-flood 24.7t / d rose to the current 42t / d, but also exposed the reservoir geology, oil production process set And safety and environmental protection and other aspects of a series of questions, for the next high-ups cooperation block full diversification has accumulated rich experience.
