| 1 | Quantitative characterization of reservoir space in the Lower Silurian Longmaxi Shale,southern Sichuan,China显示文摘Based on the drilling data of the Upper Ordovician Wufeng Shale and the Lower Silurian Longmaxi Shale in southern Sichuan Basin,the construction of matrix pores and the development condition of fractures in a marine organic-rich shale are quantitatively evaluated through the establishment of the reservoir petrophysical models and porosity mathematical models.Our studies show that there are four major characteristics of the Longmaxi Shale confirmed by the quantitative characterization:(1)the pore volume of per unit mass is the highest in organic matter,followed in clay minerals,finally in brittle minerals;(2)the porosity of the effective shale reservoir is moderate and equal to that of the Barnett Shale,and the main parts of the shale reservoir spaces are interlayer pores of clay minerals and organic pores;(3)the porosity of the organic-rich shale is closely related to TOC and brittle mineral/clay mineral ratio,and mainly increases with TOC and clay mineral content;(4)fractures are developed in this black shale,and are mainly micro ones and medium-large ones.In the Longmaxi Shale,the fracture density increases from top to bottom,reflecting the characteristics with high brittle mineral content,high Young’s modulus,low Poisson's ratio and high brittleness at its bottom. | WANG YuMan DONG DaZhong YANG Hua HE Ling WANG ShiQian HUANG JinLiang PU BoLing WANG ShuFang | 2014 | Science China Earth Sciences2014，57，2： | 36 |
| 2 | Differences between Marine and Terrestrial Shale Gas Accumulation:Taking Longmaxi Shale Sichuan Basin and Yanchang Shale Ordos Basin as Examples显示文摘1 Introduction With the rapid development of theory and practice,shale gas has gradually become an important part in diversified energy structure.Though a lot of research have been done mainly for shale gas exploration prospects,geological conditions and shale gas accumulation have been analyzed and summarized,prospective resources have been preliminarily predicted,and favorable exploration | PU Boling DONG Dazhong ZHAO Jingzhou ER Chuang HUANG Jinliang | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 3 |

| 4 | OPTIMAL DECAY RATE OF THE COMPRESSIBLE QUANTUM NAVIER-STOKES EQUATIONS显示文摘For quantum fluids governed by the compressible quantum Navier-Stokes equations in R^3 with viscosity and heat conduction, we prove the optimal L^p- L^q decay rates for the classical solutions near constant states. The proof is based on the detailed linearized decay estimates by Fourier analysis of the operators, which is drastically different from the case when quantum effects are absent. | Xueke Pu Boling Guo | 2016 | Annals of Applied Mathematics2016，32，3： | 1 |
| 5 | Regular solutions for multiplicative stochastic Landau-Lifshitz-Gilbert equation and blow-up phenomena显示文摘The two-dimensional Landau-Lifshitz-Gilbert equation of motion for a classical magnetic moment perturbed by a multiplicative noise is considered. This equation is highly nonlinear in nature and, for this reason, many mathematical results in stochastic partial differential equations (SPDEs) cannot be applied. The aim of this work is to introduce the difference method to handle SPDEs and prove the existence of regular martingale solutions in dimension two. Some blow-up phenomena are presented, which are drastically different from the deterministic case. Finally, to yield correct thermal-equilibrium properties, Stratonovitch integral is used instead of Ito integral. | PU XueKe 1, & GUO BoLing 2 1 College of Mathematics and Statistics, Chongqing University, Chongqing 400044, China 2 Institute of Applied Physics and Computational Mathematics, P.
