Emulsion explosive density influencing its pressure desensitization is mainly due to the emulsion breakage around the density regulator particulates.

Feasibility study and effect evaluation on infill adjustment in Mu 147 fault block.;

Taking Gaotaizi infill adjustment area in Sanan oilfield as an example,the oil remaining potentials and distributions were known by multidisciplinary reservoir analysis,and the quantitative description of oil remaining in each sedimentation unit was realized.

Applications of C/O log result in good effect in identifying flood layer,direct perforation-selecting in new well or perforation-adding in old well,as well as block off,etc,in middle and high porosity and permeability region,and provide bases for infill adjustment and syntheses measure.

The paper gives a design of four-DOF precision adjustment mechanism.

This paper introduces the structure and operating principle of double eccentric mechanism used in a special environment to realize the two-dimension precision adjustment, establishes its precise mathematic model, analyzes the theory model with simulation model, and researches it by test.

To accomplish a task of optical precision adjustment,a 6-DOF precise parallel robot with architecture of HTRT is presented,which is driven by AC servo motors.
