The electrophysical property of saturated rocks is very important for reservoir identification and evaluation. In this paper, the lattice Boltzmann method （LBM） was used to study the electrophysical property of rock saturated with fluid because of its advantages over co.ventional numerical approaches in handling co.plex pore geometry and boundary co.ditions. The digital co.e model was co.structed through the accumulation of matrix grains based on their radius distribution obtained by the measurements of co.e samples. The flow of electrical current through the co.e model saturated with oil and water was simulated on the mesosco.ic scale to reveal the non-Archie relationship between resistivity index and water saturation （I-Sw）. The results from LBM simulation and laboratory measurements demonstrated that the I-Sw relation in the range of low water saturation was generally not a straight line in the log-log co.rdinates as described by the Archie equation. We thus developed a new equation based on numerical simulation and physical experiments. This new equation was used to fit the data from laboratory co.e measurements and previously published data. Determination of fluid saturation and reservoir evaluation co.ld be significantly improved by using the new equation.

This paper presents a new aquathermolysis study of co.ventional heavy oil in superheated steam. A new high temperature autoclave was designed, where volume and pressure co.ld be adjusted. Aquathermolysis was studied on two different co.ventional heavy oil samples under different reaction times and temperatures. Experimental results show that aquathermolysis does take place for co.ventional heavy oil. As reaction time increases, the oil visco.ity reduces. However, the reaction will reach equilibrium after a certain period of time and won＇t be sensitive to any further reaction time any more. Analysis shows that, while resin and asphaltenes decrease, saturated hydrocarbons and the H/C ratio increase after reaction. The main mechanism of aquathermolysis includes hydrogenization, desulfuration reaction of resin and asphaltenes, etc.

为深入探讨煤对甲烷气体吸附—解吸机理及可逆性,作者从物理化学和界面化学以及现代煤层气吸附理论的角度,并通过系统的煤对甲烷气体吸附—解吸可逆性物化模拟实验,进一步科学地求证了煤对甲烷气体吸附—解吸可逆性问题。根据理论分析和实验成果,明确地提出了:①煤对气体分子的物理吸附特性决定了吸附与解吸的可逆性;②吸附在煤内表面的甲烷分子被解吸需要一定的能量,以摆脱煤表面与甲烷分子之间的范德华力,因此解吸过程会不同程度地滞后于吸附。

火山是地球物质重新分配的一种形式。火山的成因是地幔中物质的态变而导致物质分异,进而导致地幔顶层物质置换,物质置换导致置换空间的载荷下降,进而导致浮力上升,最终导致火山喷发。火山的形成条件有3个:置换物质、置换空间和喷发通道。火山的存在状态有5种:常流火山、间喷火山、开口火山、终结火山和未喷火山。火山的存在状态与物质的置换速度相关,物质置换速度又与固体物质态变速度相关。火山喷发是地球内部物质排放,它会导致地球体变,即地壳运动。火山喷发的强度与地壳的厚度成正比,地壳较薄时以溢流为主,地壳较厚时才能聚集更大的压力。火山内部的压力与置换高度和置换物质的密度相关,根据置换高度和置换物质的密度可以计算火山内部的压力。火山的分布与地幔中固体物质的分布相关。地史早期的火山分布主要受撞击星子的影响,晚期的火山分布主要受俯冲板片的影响。
