查询词典 sand blast apparatus

Given the Duri oil field adjacent to the consolidation of sand there is not serious sand greatly reduced pump rod pump efficiency, and horizontal wells using the naked eye is difficult to control completion of prefabricated sieve out the sand, so the use of horizontal wells Kulin tolerance strata of sand Rodless pump artificial lift.

鉴于相邻的Duri油田有不固结砂，严重的出砂大大降低了有杆泵泵效，而水平井采用裸眼预制筛管完井难以控制出砂，因此Kulin水平井采用耐受地层出砂的无杆泵进行人工举升。

The field experiments on the secondary flow developed on the lee side show that there are strong sand transport potential at the lee side of the dunes near the surface because of the decreasing of the sand grain size and the other factors. The transport directions are nearly vertical to the dune trends. Those factors and the sand slumping on slip face, and the sand transport processes on the stoss slope make the transverse dunes maintaining their morphology under the advance processes.

对沙丘背风坡发育的二次流的野外观测表明，近地面一定高度内沙丘背风坡气流仍有一定的强度，由于背风坡的沙丘沙粒径较小等因素，背风坡气流仍保持一定强度的输沙率，输沙方向与沙丘走向基本上垂直，这种作用与沙物质向背风坡崩落、迎风坡的输沙过程等共同作用，因而使横向沙丘在运动中保持其形态。

Finally, the thesis analyzes statistical laws of the maximum saltating height and saltating length of saltating sand grains and they follow Gamma function distribution. This is consistent with the results of water-sand motion. It shows that statistical laws of saltating height and saltating length of saltating sand grains are independent of the medium of flow. It is possible the nature of saltating sand grains.

最后，分析了沙粒跃移距离、跃移高度的相对量的统计规律，认为它们均服从Gamma函数分布，与在含沙水流中的研究结果一致，说明沙粒跃移运动的跃移高度与跃移距离的统计规律与流场、所处的介质无关，这可能是沙粒跃移运动的本质所在。
