寻找非构造油气藏的新思路

目前,一种新的理论体系和研究方法已经形成,并正在发展和逐步完善。那就是层序地层学和油气成藏系统理论的诞生和发展;以及由计算机的快速发展带动起来的地震测井资料的采集、处理、显示和各种地质问题的计算机模拟技术,使得地质学和石油地质学都在朝着从定性到定量,从推测到更科学的预测方向发展。在今后的5～10年中,中国的石油地质家们不仅要注意方法和技术方面的进步,还应当重视在陆相层序地层学和陆相层序中油气成藏机制等基本理论方面的研究。     

用边界拟合坐标下的有限差分法评价城市的地下水资源

本文给出了边界拟合坐标系下的二维地下的二维地下水流的基本方程，并且用该坐标系下的有限差分法对江苏某市的承压水和潜水资源进行评价。预测了１９９１－２０００年的地下水流场，边界拟合坐标下的ＡＤＩ法的计算结果和实测水位比较一致，表明该方法在地下水资源评价中有实际应用价值，尤其在处理边界几何形状复杂的地下水流问题时更为有效。

Finances and Well-Being: A Dynamic Equilibrium Model of Resources.

This study of 513 Dutch farmers tested a dynamic equilibrium model of resources (an extension of the conservation of resources theory; S. E. Hobfoll, 1989, 1998, 2001). With structural equation modeling, the advantages of a 3-wave longitudinal design were comprehensively used, such as addressing bidirectional causal effects and within-individual vs. between-individual change. This allowed for a careful analysis of the management function of resources in the stress process. Results showed that well-being had stronger within-person stability than finances. Increased levels of financial problems temporarily increased psychological distress but not self-reported illness. Conversely, farmers with higher stable baselines of psychological distress also had higher baselines of self-reported illness and experienced more negative changes in their financial situation.

Wind energy resource assessment for five locations in Saudi Arabia

The analysis of recently collected wind data at five sites in Saudi Arabia namely, Dhulum, Arar, Yanbu, Gassim and Dhahran is presented. The five sites represent different geographically and climatologically conditions. The data collected over a period spanned between 1995 and 2002 with different collection periods for each site. Daily, monthly and frequency profiles of the wind speed at the sites showed that Dhulum and Arar sites have higher wind energy potential with annual wind speed average of 5.7 and 5.4 m/s and speeds higher than 5 m/s for 60 and 47% of the time, respectively. The two sites are candidates for remote area wind energy applications. The costal site's, i.e. Yanbu and Dhahran wind speed data indicated that the two sites have lower annual wind speed averages and wind blows at speed higher than 5 m/s during afternoon hours. That makes the two sites candidates for grid connected wind systems for electrical load peak shaving. The data of Gassim site showed that the site has the lowest wind energy potential compared to the others. The annual energy produced by a Nordex N43 wind machine is estimated to be 1080, 990, 730, 454 and 833 MWh for Dhulum, Arar, Yanbu, Gassim and Dhahran, respectively. The analysis showed that the estimated annual energy produced by the machine based on 10 min averaged data is 2.5% higher than the estimated energy based on 30 min averaged data.

中国碎屑岩隐蔽油气藏勘探进展与问题

介绍了中国陆上与海上碎屑岩隐蔽油气藏的勘探历程.总结了伴随碎屑岩隐蔽油气藏勘探过程中新理论新技术的进展情况,理论上包括层序地层理论在中国的不断创新、坡折带理论、复式输导体系、相势控藏及三元控藏理论,这些理论推动了隐蔽油气藏从个别识别到定性和定量预测,促进了盆地不同构造位置、不同层系、不同领域隐蔽油气藏的勘探;技术上主要体现在高精度层序地层研究、为高精度层序地层研究而发展的保幅处理和高分辨率处理技术、验证和预测隐蔽砂体的反演技术、隐蔽砂体快速直观识别的可视化技术、分析隐蔽砂体含油性的AVO技术及分频等地球物理技术.尽管如此,隐蔽油气藏勘探失败案例暴露了许多问题,这些问题在于缺乏系统运用隐蔽油气藏理论或者由于隐蔽油气藏成藏理论不完善难以准确快速评价是否成藏,此外,由于地球物理预测具有多解性也会导致错误的认识.因此,今后应充分利用高分辨率地震资料,大力推进叠前处理和反演技术,进一步弄清隐蔽油气藏成藏机理及主控因素.

Hydrocarbon exploration risk evaluation through uncertainty and sensitivity analyses techniques

The evaluation of the exploration risk in the oil industry is a fundamental component of the decision process related to the exploratory phase. In this paper the two basic components of the exploratory risk: trap geometry and trapped hydrocarbon quantities (fluid), are compounded in a single coherent uncertainty and sensitivity approach. The results clarify that the model geometry influences each Petroleum System Modeling step and that the geometric uncertainty is correlated with the fluid uncertainty. The geometric uncertainty evaluation makes use of geostatistical techniques that produce a number of possible realizations of the trap geometry, all compatible with available data. The evaluation of the fluid uncertainty, through a Monte Carlo methodology, allows us to compute the possible quantities of oil and gas, generated in a basin and migrated from the hydrocarbon source location to each single trap. The final result is the probability distribution of oil and gas for each trap in the basin, together with other useful indicators like: the hydrocarbon filling probability map, the closure probability map, the drainage area probability map, the spilling paths probabilities, the trap-filling scenarios.
