A sputtering target and a backing plate are diffusion-bonded with or without an insert or inserts interposed there-between so as to have a solid phase diffusion-bonded interface. The sputtering target substantially maintains its metallurgical characteristic and properties even though it has been diffusion-bonded to the backing plate. The solid-diffusion bonding of the target and backing plate, is achieved at a low temperature and pressure and results in interdiffusion of constituent atoms to attain high adhesion and bond strength without attendant deterioration or large deformation of the target material, while inhibiting the crystal growth in the target material. The bond undergoes no abrupt decrease in bond strength upon elevation of the service temperature. One hundred percent bonding is achieved with non-bonded portions such as pores left along the interface.

The invention provides a reservoir capillary pressure curve determinator under a high temperature and a pressure. The determinator comprises a ring pressure system, an injection system, a core clamping system, a semi-permeable baffle plate, a back pressure system, a measuring system, a data automatically collecting and processing system, and a thermostat which are connected through pipelines. A semi-permeable baffle plate method is adopted to measure capillary pressure curves under a stratum condition, and the basic rationale is that a principle of balance between an impressed pressure and the capillary pressure is used to measure the capillary pressure curves under the high temperature and the pressure. Core saturated wetting phase fluid displaces a wetting phase with a nonwetting phase under a certain displacement pressure. When the impressed pressure overcomes the capillary pressure of a certain capillary in the core, the wetting phase fluid in the capillary is discharged gradually, and the wetting phase fluid saturation in the core is reduced. Pressure is increased stepwise, accumulated discharged quantity of the wetting phase fluid when the wetting phase fluid is no longer discharged and an injection pressure are measured, and the capillary pressure curves can be solved.
