碳酸盐岩双孔隙网络模型的构建方法和微观渗流模拟研究

碳酸盐岩油藏作为全球的主力油气储集层,在微观尺度上分布有大量发育的大孔隙和微孔隙,研究不同孔隙对其微观渗流特征的影响具有重要意义．本文基于碳酸盐岩中分别描述大孔隙和微孔隙特征的单一尺度孔隙网络模型,利用整合法构建出能够同时描述大孔隙和微孔隙特征的双孔隙网络模型,最后模拟各网络模型的渗流过程,计算相应的渗流特征参数并同岩心实验室渗透率进行了对比．结果表明,基于整合法构建的双孔隙网络模型可根据区间域随机产生任意大小的网络尺寸,不仅同时包含大孔隙和微孔隙的几何拓扑结构信息,而且可同时描述大孔隙和微孔隙的渗流特征,能够较好描述真实碳酸盐岩油藏中多尺度孔隙特征．双孔隙网络模型的绝对渗透率和实验室岩心结果基本一致,水湿油藏条件下对比各网络模型的相对渗透率曲线发现,双孔隙网络模型的等渗点含水饱和度均大于大孔隙和微孔隙网络,其残余油饱和度明显减少,这是由于大孔隙和微孔隙的整合极大地提高了双孔隙网络的连通性,进而大幅度提高网络的渗流能力,本研究为碳酸盐岩微观渗流研究提供了重要的理论基础．     

State of the art for dry tree semi technologies

Dry tree semi is a fast developing technology and becomes more and more appealing to the operators as a solution for producing deepwater reserves. Utilizing a dry tree semi means spending less cost on well mainte-nance and interventions,while the production platform can be integrated and commissioned at quayside. This paper presents a comprehensive overview of various technologies for dry tree semi,such as E-semi,T-semi,paired-column semi and long stroke tensioners. Each dry tree semi concept is briefed in terms of global performance,top tension riser (TTR) tensioner system,quayside integration and feasibility to environment.

Building a high-resolution regional climate model for the Heihe River Basin and simulating precipitation over this region

Based on the Regional Integrated Environmental Model System （RIEMS 2.0） developed by START TEA-COM RRC and Department of Atmospheric Science of Nanjing University, a dataset of observation and remote sensing over the Heihe River Basin （HRB） was used to recalibrate the model＇s parameters, including topography elevation, land cover type, saturated soil water po- tential, saturated soil hydraulic conductivity, field moisture capacity, wilting point moisture, soil porosity, and parameter b of soil hydraulic conductivity, to build a high-resolution regional climate model for the HRB. Continuous simulation for the period from January 1 to December 31, 2000 was conducted using the regional climate model, with NCEP-FNL reanalysis data as the driving fields. The study focused on the ability of the model to simulate precipitation in the HRB. The analysis results showed the following： （1） For precipitation, the model could reproduce well the spatial pattern and seasonal cycle in different regions of the HRB, simulated precipitation was overestimated in the upper reaches of the HRB and underestimated in the lower reaches of the HRB, and seasonal precipitation biases were mostly in the range of -39.9%-9.6% of observations, which is mostly consistent with the IPCC report （2001）. （2） The model could reproduce reasonably temporal evolution of pentad precipitation in different regions. Correlation coefficients between the simulated and observed pentad precipitation were 0.8123, 0.5064, and 0.7033 in the upper, middle, and lower reaches of the HRB, respectively. They reached a significance level of 1%. （3） Dynamical downscaling of a high-resolution regional climate model was used to overcome the deficiency of long-term, high-temporal/spatial-resolution meteorological dataset in the HRB, and to drive directly the integrated model that coupled ecological-hydrological and socioeco- nomic processes in the HRB.
