Abstract:

 The relations of net overburden pressure with rock porosity and permeability under the reservoir condition are important for reserve calculation and study of oil and gas field development. Through CMS-300 overburden pressure test system, combined with core mercury injection, cast thin section, scanning electron microscope, field emission and many other experimental analysis data, this paper studied the difference of the relationship between porosity,permeability and the net overburden pressure under the reservoir condition and conventional reservoir condition. The results show that: ①with the increase of net overburden pressure, the overburden pressure porosity and permeability are diminishing with power function; ②compared with the low porosity and low permeability re servoir, the loss ratio of tight oil porosity and permeability caused by compaction is smaller; ③after the pressure recovery, the porosity and permeability of tight oil can return to the initial value almost, so the tight oil sample has good elasticity.
