Due to the slim hole at the lower part of the ultra-deep and deep wells, the eccentricity and rotation of drill string and drilling fluid properties have great effects on the annular pressure drop. This leads to the fact that conventional computational models for predicting circulating pressure drop are inapplicable to hydraulics design of deep wells. With the adoption of helical flow theory and H-B rheological model, a computational model of velocity and pressure drop of non-Newtonian fluid flow in the eccentric annulus was established for the cases where the drill string rotates. The effects of eccentricity, rotation of the drill string and the dimensions of annulus on pressure drop in the annulus were analyzed. Drilling hydraulics was given for an ultra-deep well. The results show that the annular pressure drop decreases with an increase in eccentricity and rotary speed, and increases with a decrease in annular flow area. There is a great difference between static mud density and equivalent circulating density during deep well drilling.

The delamination near the centre crack of ARALL under fatigue and static loads is investigated, and the effects on delamination by different residual stresses are analyzed. The results show that the situations under the two kinds of loads are *** the fatigue load, the typical delamination with crack growth presents symmetrical hi-ellipse-shape, whereas under the condition of static tensile, the edge-effect becomes more evident. Applying a proper pre-stress to the laminate can increase the ability of anti-delamination damage.

Interlayer slipping breccia-type gold deposit-a new type of gold deposit,defined recently in the northern margin of the Jiaolai Basin,Shandong Province,china-occurs in interlayer slip faults distributed along the basin *** has the features of large orebody thickness(ranging from 14 m to 46 m,with an average thickness of 3. m),shallow embedding(0-50 m thickness of cover),low tenor of gold ore (ranging from 3.g/t to 5 g/t),easy mining and ore *** type of gold deposit has promising metallogenic forecasting and potential for economic exploitation. A ground gamma-ray survey in the Pengjiakuang gold-ore district indicates that the potassium/thorium ratio is closely related to the mineralization intensity,*** larger the potassium/thorium ratio,the higher the *** gold mineralized alteration zone was defined by a potassium/thorium ratio of 0.3..A seismic survey confirms the location of the top and bottom boundaries and images various features within the Pengjiakuang gold mineralization *** gold-bearing shovel slipped belt dips to the south at an angle of 50-55°at the surface and 15-20°at depth. The seismic profile is interpreted in terms of a structural band on the seismic section characterized by a three-layered *** upper layer is represented by weakly discontinuous reflections that represent the overlying conglomerates.A zone of stronger reflections representing the interlayer slip fault(gold-bearing mineralized zone) is imaged within the middle of the section,while the strongest reflections are in the lower part of the section and represent metamorphic rocks at *** the same time,the seismic reflection survey confirms the existence of a granite body at depth,indicating that ore-forming fluids may be related to the granite.A CSAMT survey showed that the gold-bearing mineralized zone is a conductive layer and contains a low-resistivity anomaly ranging from 2Ωm to 200Ωm.

A glassy Zr41Ti14Ni8Cu12.5Be22.5Fe2 rod with a diameter of 9 mm was successfully pro-duced by water puenching. The effects of iron addition on thermal stability and hardness of Zr41Ti14Ni8Cu12.5Be22.5Fe2 bulk amorphous alloy were investigated by XR D, DSC and microhardness test. it is found 1that the full annealing would enhance the strength of the alloy significantly. The cause of the increase in hardness was analyzed and the formation mechanisms of the bulk amorphous alloy are discussed.
