摘要
将吐哈油田玉西区块深层稠油天然气吞吐试验与国外稠油二氧化碳吞吐对比,吐哈玉西深层稠油天然气吞吐天然气利用率高,增油效果好。通过国内外文献调研及数值模拟研究,提出了进一步提高玉西深层稠油天然气吞吐开发效果的3项主要措施:提高注气速度及增大压裂半径;试验不同比例的天然气混合气体吞吐方式、注水保持压力。
Compared with CO2 huff and puff for producing heavy oil at abroad,the pilot test of natural gas huff and puff for deep heavy oil in the Yuxi block of the Tuha oilfield has seen high natural gas utilization rate and remarkable oil increment.Through literature investigation and numerical simulation,three methods are proposed to further improve the development effect of natural gas huff and puff,i.e.to improve gas injection rate and fracturing radius,to test for hybrid gas huff and puff at different gas proportions,and to maintain reservoir pressure by injecting water.
