Using harmonic analysis of the calculated tidal level and current, the distributions of co-tidal lines for K1, O1, M2 and S2 are obtained, whose maximum amplitudes can reach 112 cm, 96 cm, 50 cm and 15 cm, respectively. The distribution of the maximum probable current velocities in Qinzhou Bay is basically the same as that of isobaths, and the maximum probable current velocity can reach 200cms^(-1) nearby the Longmen Harbor. It is concluded by the analysis of K1 and M2 tidal current ellipses that the flow is rotating at the mouth of the bay, while its retilinear flow is in the nearshore area, estuaries and channels. The distributions of the major axes are closely related to the topography, and the rotation directions of both constituents are clockwise.

In operation, the downhole devices will be laid down with tubings which will move up and down using the operation machine. Since the injection head can rotate in the determined speed, the rotating flow, compared with the conventional stable axial flow, can prevent the sands from depositing in the horizontal annular and washing the screen. The jet from high-efficiency jet nozzle will wash the screen directly with concentrated hydro-power. The working fluid can be clean water, without damage to the formation.

作业时用油管下入该井下装置，利用作业机带动油管上下移动，由于喷头可按照既定速度旋转，返回流体在水平段由常规的平稳轴向流动变为旋转流动，既可实现对防砂管的全方位解堵，又能避免砂粒沉积；高效喷嘴产生的射流直接对着防砂管冲击，能量集中；工作介质为清水，不会对地层带来二次污染。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.
