近年来,我们在压裂工艺技术、压裂液和压裂设备的研究改进方面,做了许多工作,取得了很好的成果。现在我们拥有50个压裂酸化车组,有500多台主机和1000台辅助车辆,每年完成压裂工作量约5000井次,增产原油200多万吨,队伍和装备,在世界上是名列前茅的。但在技术方面还比较落后。现在,在压裂领域中,除了大庆油田不断发展分层压裂和选择性技术,连年获得较好增产效果外,其他如渤海湾地区深层压裂,长期未能突 In recent years, we have done a lot of work on the improvement of fracturing technology, fracturing fluid and fracturing equipment and have achieved very good results. Now we have 50 fracturing and acidifying carriages, more than 500 mainframes and 1,000 auxiliary vehicles, completing fracturing work volume of about 5,000 wells each year and increasing production of more than 2 million tons of crude oil, with ranks and equipment ranked among the best in the world . But in terms of technology is still relatively backward. Now, in the field of fracturing, in addition to the continuous development of fracturing and selective technologies in Daqing Oilfield, it has achieved good stimulation effects in successive years. For example, the deep-sea fractures in the Bohai Bay area have failed to burst
