Pressure-while-drilling measuring device and measurement method thereof

ActiveCN102121377ASave drilling timeAvoid difficulty in going down wellSurveyPush outEngineering
The invention relates to a pressure-while-drilling measuring device and a measurement method thereof. The pressure-while-drilling measuring device is characterized by comprising an outer shell in which a central flow channel is formed; the outer shell is provided with a split-flow pressurization mechanism, an execution mechanism and an oil line reversing mechanism sequentially; the execution mechanism is provided with a pumping mechanism; the split-flow pressurization mechanism controls the opening and closing of the execution mechanism by using the acting force of slurry in the central flow channel and a split-flow piston; and the execution mechanism and the oil line reversing mechanism are matched with each other to push out and reset all sliding blocks in the pumping mechanism, so thatthe stretching and retraction of a probe can be realized, and bottom fluid is pumped by a pumping cylinder and a piston rod of the pumping mechanism and is measured. The pressure-while-drilling measuring device can accurately acquire the underground formation pressure in real time, staff can timely identify the complex underground geological factors by using the formation pressure data and further adjust the drilling parameters, and the complex conditions of leakage, collapse, overflowing, blowing and the like during drilling can be effectively avoided, so that the pressure-while-drilling measuring device can be widely used in the drilling process.

Integration device for stacking, bundling and labeling bank notes and tickets

The invention discloses an integration device for stacking, bundling and labeling bill coupons. The integration device comprises a controller, a stacking mechanism, a bundling mechanism and a labeling mechanism, wherein a bill coupon stack transfer mechanism is arranged between the stacking mechanism and the bundling mechanism; a bill coupon bundle transfer mechanism is arranged between the bundling mechanism and the labeling mechanism; the stacking mechanism can be connected with a bill dispenser port of a sorter for stacking a certain quantity of bill coupons into bill coupon stacks and sending the bill coupon stacks to the bundling mechanism to bundle the bill coupon stacks into bill coupon bundles; and then the bill coupon bundles are transferred into the labeling mechanism through the bill coupon bundle transfer mechanism to finish labeling the bill coupon bundles. Due to the stacking mechanism, the defect of inclined bill coupon bundles caused by consistent direction of all bundling belts during stacking the bill coupon bundles is overcome. In addition, a guide block is also arranged, so that a PE (Poly Ethylene) film stretched due to the influence of a heat-seal knife faces downwards when a product is sent to the labeling mechanism, and the label cannot be unrecognized because of deformation, cracking or dropping out after labeling. The integration device can be used as a pre-seal bundling machine and lays a better foundation for the intellectualization of a packet processing system.

Mandibular condyle fracture reduction dilator

A mandibular condyle fracture reduction dilator comprises two forceps handles which are connected in a cross hub manner. Front ends of the two forceps handles are dilating portions while rear ends of the two forceps handles are holding portions, the dilating portions comprise a lower dilating portion and an upper dilating portion, the lower dilating portion matches with a mandibular incisura, and the upper dilating portion matches with a zygomatic arch corresponding to the mandibular incisura. The mandibular condyle fracture reduction dilator further comprises a positioning component for locking a gap between the upper dilating portion and the lower dilating portion, the positioning component comprises a screw stem and a nut matching with the screw stem, the screw stem is provided with a scale graduation area for displaying the size of the gap between the upper dilating portion and the lower dilating portion, the holding portions comprise an upper holding portion and a lower holding portion which match with each other, a perforated hole is arranged on the lower holding portion, one end of the screw stem penetrates through the perforated hole to be pivotally connected with the upper holding portion, and the nut is sleeved at the other end of the screw stem in a screwed manner, and is located on the outer side of the lower holding portion. The reduction dilator can be used for directly operating in a surgical site of the maxillofacial region of a patient, exerts force on the outside of the oral cavity of the patient, leads joint clearances to be exposed easily, and is convenient in operation, an additional incision is omitted, and tissue injury is low.

3D curved surface AF coated screen mobile phone protective film and preparation method thereof

The invention discloses a 3D curved surface AF coated screen mobile phone protective film and a preparation method thereof. A hardened layer, a PET layer with the polarization angle of 70-100 degrees, a modified photo-thermal dual-curing acrylic polyurethane layer, a non-optical-axis optical elastic layer and a special silica gel pressure-sensitive adhesive layer for an AF screen are adopted as main structures; thenon-optical-axis optical elastic layer has no polarization angle; an upper protection layer can realize a self-separation function, and the modified photo-thermal dual-curing acrylic polyurethane layer adopts specific material components, so that both thermal curing and photo-curing can be carried out. The protective film and the preparation method thereof have the advantages that bending forming molds of different specifications do not need to be customized according to the sizes of different 3D curved surface AF coated screen mobile phones during production, forming can be completed only through cutting and flaking, film pasting can be achieved at a client side in the follow-up process only through positioning film covering and ultraviolet lamp UV curing and attaching, hot-pressing high-temperature operation and demolding are not needed in the whole process, the overall production efficiency is remarkably improved, and the production cost is greatly reduced.
