深井试油攻关组,是根据一九七五年全国石油勘探开发科技会议的决定,由大庆、胜利、江汉等油田的八名同志和大港油田有关同志共同组成的,在大港油田开展了攻关试验,在深井试油方面取得了一定成绩。试油工艺方面:在三口井进行了封隔器分层试油新工艺试验。1.用现有的251-5、151型封隔器、JG-2型胶筒,在板870井封隔器下至井深2700多米,上下压差200大气压,井下温度100℃以上,封隔器在井下工作10天后仍正常。在板846井,封隔器在井深2660米左右,140大气压下,在井内停留26天,起出胶筒仍然完
According to the decision of the National Petroleum Exploration and Development Science and Technology Conference in 1975, the deep well test set consists of eight comrades in Daqing, Shengli, Jianghan and other comrades in Dagang Oilfield and carried out tackling tests in Dagang Oilfield , In the deep well oil test has made some achievements. Test oil process: a packer stratified oil test in three wells new technology test. 1. With the existing 251-5,151 packers, JG-2 plastic cartridge, under the packer in the well 870 well down to depth of more than 2700 meters, pressure up and down 200 atm, downhole temperature above 100 ℃, packer The device is still working 10 days downhole. In Well 846, packer 2660 meters in depth, at 140 atmospheric pressure, stay in the well for 26 days, play a plastic cartridge is still finished
