The sandstone grain sizes of cores in YC35-1-1 and YC35-1-2 wells are analogous (mainly middle-fine sandstones and very fine sandstones), and their content of interstitial materials are both less than 10%.
However the intergranular volume (including interstitial materials and pores) of these two wells is basically the same, which indicates the decrease of reservoir porosity by compaction with depth in YC35-1-2 is obviously lower than that in YC35-1-1.

An Investigation on the Nose Mass Abrasion of Projectile Fei Qian1, Haijun Wu*1,a, Fenglei Huang1, Yinan Wang1 1State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing, 100081, China *awuhjbit@hotmail.com (corresponding author) Key words: Mass abrasion, High-speed penetration, Kinetic energy penetrator, Concrete target Abstract: Based on the dynamic spherical cavity expansion theory of concrete and the analysis of experimental data, a mass abrasion model of projectile considering the hardness of aggregates, the relative strength of target and projectile and the initial impact velocity is constructed in this paper.
However, relatively speaking, the sensitivity of strength of projectile to mass abrasion is higher, which indicates that the effect of projectile material on mass abrasion is more important than the hardness of aggregates. 1 Introduction The mass abrasion of projectile would occur obviously in high-speed penetration.
The hardness of aggregates and the strength of projectile is also the significant factor, but relatively speaking, the sensitivity of the strength of projectile to mass abrasion is higher, which illustrates that the effect of projectile material on mass abrasion is more important than the influence of the hardness of aggregates.
