The blasting test demonstrates that the horizontal stress wave contributes more to water drainage than vertical stress wave, reducing water drainage distance is favorable to squeezing water and consolidation of soil, the blasting powder amount influences test result greatly. 爆炸试验表明,水平向应力波对土体排水的贡献大于竖向应力波,缩短排水距离有利于土体的排水固结,炸药用量对试验有很大影响。
The diversification of the competitive entities and resources in the market is squeezing the profits of petroleum companies which results in severe test of competition, survival and development of them. 市场竞争主体和资源的多元化,使得石油企业的盈利空间进一步受到挤压,石油企业面临着竞争、生存与发展的严峻考验。生存与发展环境的巨大变化,迫使胜利油田必须做出战略抉择。
