摘要: 伴随着“两会”的春风,西南石油大学学报2008年第2期如期与您相见。
  2008年3月5日,国务院总理温家宝在十一届全国人大一次会议上所作的政府工作报告中指出:2008年工作的主要任务包括“实施基础研究、高技术研究和科技支撑计划以及优先发展教育”。与此相呼应,本期的学报具有以下两大特点:(1)及时报道了我国石油工业主要领域的科技成果(国家级重大科研基金资助论文11篇);(2)体现了我国石油天然气行业高校师生的学术水平(84%的文章第一作者来自全国8所高校)。
  资料显示,2007年中国生产天然气693.1×108 m3,并预计2008年天然气产量将达到760×108 m3。四川盆地东北部三叠系飞仙关组是近年来我国发现的重要天然气储集层,可采储量已达5 000×108 m3左右,川东北已成为我国油气的重点勘探地区之一。西南石油大学教授、博士生导师司马立强结合国家863专项研究课题(2006AA06Z220)的研究成果,撰写了《川东北飞仙关组储层孔隙度计算方法探讨》。详细讨论了缝洞对三孔隙度曲线的影响,提出了缝洞性储层求取孔隙度的新思路及模型计算方法,该方法提高了孔隙度计算精度,值得借鉴。
  《大尺度溶洞裂缝型油藏试井新模型》由“油气藏地质及开发工程”国家重点实验室博士(后)彭小龙等人撰写,从主要特征、试井模型、实例分析方面针对常规试井模型解释结果与大尺度缝洞型油藏地质特征不相符问题,以一个缝洞和两个缝洞为例,建立了拟稳态条件下的流动方程,采用Laplace变换和逆变换,得到实空间的解析解。其研究内容为国家重点基础研究发展计划973项目(2006CB202403)的部分研究成果,对于石油天然气工程及其相关领域的研究具有重要的指导意义。
  受世界石油供需变化的影响,如何在新形势下调整产品结构、合理利用有限资源,成为石蜡开发应用值得关注的热点问题。成都理工大学教授、博士生导师汪灵在国家自然科学基金资助项目、国家“十五”科技攻关计划重点项目研究的基础上,撰写了《硬脂酸对石蜡熔点及力学性能的影响》,其研究成果对石蜡在工业中的进一步运用有一定的参考价值。
  提高硬地层钻井速度是世界公认的钻井难题。从事钻井工程的读者不妨阅读一下由西南石油大学副教授伍开松等人撰写的《粒子冲击钻井技术述评》。论文以粒子冲击钻井系统的整个工艺流程为依据,评述了粒子冲击钻井技术的优点和缺点,阐述了其破岩机理,推介了一种高效经济的深井硬地层钻井的新方法。
  《油田产量构成二层规划模型及其应用》由西南石油大学教授谢祥俊等人完成,论文针对目前油田的实际管理组织结构,采用二层规划模型,对油田生产过程中的最优化问题进行了研究。模型应用于国内多个中、后期开发油田的开发规划中,产生了很好的经济效益。研究内容对油田生产规划具有一定的指导意义。
  库车拗陷位于塔里木盆地北部南天山山前地区,是近年来塔里木盆地油气勘探的主战场。中国石油大学教授、博士生导师汤良杰率领的研究团队在国家自然科学基金项目、国家“973”计划项目研究的基础上,撰写了《库车西秋里塔格构造带中、新生代构造演化》,根据平衡剖面原理,对两条地质剖面进行构造复原,结合两口井的沉降史分析,研究得出了该带中、新生代的构造演化特征。对于该区下一步的油气勘探具有重要的指导意义。
  一年之计在于春。我们在春天播种希望,希望广大读者一如既往地对学报给予关心和支持,多提宝贵意见,帮助改进工作。让我们共同努力,把西南石油大学学报办得更好!

Abstract: Along with the spring of the "two sessions", the second issue of 2008’s Journal of Southwest Petroleum University is on schedule to meet you.
On the March 5, 2008, Chinese Premier Wen Jiabao’s government work report at the 1st Session of the 11th National People’s Congress pointed out that: the main tasks in 2008 include "the implementation of basic research, high-tech research and technical support plans, and education priorities". Echoing this, this issue's Journal has two characteristics as follows: (1) timely reports the scientific and technological achievements of the main oil industry areas in China (11 papers of the National major scientific Fund research), (2) reflects on our oil and gas industry college academic standards (84 percent of the first author of the articles are from the national eight colleges and universities).
Data shows that in 2007 China's natural gas production is 693.1 × 108m3, and is expected natural gas production in 2008 will reach 760 × 108m3. The Triassic Feixianguan formation of Northeast Sichuan Basin is the major natural gas reservoir in China in recent years, whose recoverable reserves has reached about 5000 × 108m3, and Northeastern Sichuan has become one of the important exploration areas in China. The Southwest Petroleum University professor and doctoral tutor Sima Liqiang wrote "The Probe in Porosity Calculation Method of Fractured and Caved Reservoirs in Feixianguan Formation, Northeastern Sichuan Basin" on the basis of the National 863 Special Research Projects (2006 AA06Z220) research results. This paper detailedly discusses the fracture-cavity’s influence on three porosity curve, and proposes new idea and model calculation method of porosity calculation in fracture-cavity reservoir, which improves the calculation accuracy of the porosity, is worth learning.
The paper of "A New Well Test Model for the Big Size cavity-fracture Reservoirs" was written by the National Key Lab of Oil and Gas Reservoir Geology and Exploitation Engineering doctor (postdoctoral) Peng Xiaolong etc. Considering the problem that the well test data of constant rock reservoirs was quite different from the big size cavity-fracture reservoirs from the aspects of the main characteristics, well test models and example analyses, two pseudo-steady state flowing were set up separately for the reservoirs with one and two bulk, then Laplace transfer and inverse transfer were used to obtain the solutions in real space of the two models. The research is a part of research results of the National Basic Research Program of China "973" Program (2006CB202403), which has important guiding significance on the research of oil and gas project and related fields.
Influenced by the world's petroleum supply and demand changes, how to adjust the product structure and put resources to rational use in the new situation, are hot issues in the development and application of paraffin. Chengdu University of Technology professor and doctoral tutor Wang Ling wrote the "Influence of stearic Acid on Paraffin Melting Point on the basis of the National Natural Science Fund Project and the study of the State “The Tenth Five-year Plan” Key Science and Technology Project, whose research results have certain reference value for the further use of paraffin in oil industry.
Improving the drilling rate of hard formation is a problem in the world. The readers who engage in drilling engineering may wish to read the "Comment on Particle Impact Drilling Technology", which was written by the Southwest Petroleum University associate professor Wu Kaisong etc. According to the full operation of the particle impact drilling system, the advantages and disadvantages of the technology and the rock breaking mechanismis are described, and the technology will probably become a new method of drilling deep well hard formation efficiently and economically.
The Southwest Petroleum University professor Xie Xiangjun etc. completed the "Oil Production Composition Bilevel Programming Model of Oilfield and It’s Application", according to the current oil field practical management organizational structure, adopted the bi-level programming model, and researched the optimization problem of oil field production process. The satisfactory economic benefit can be obtained in the application of the model to the development programming in several oilfields in the mid-late stage. The research has certain significance on oil field production planning.
Kuqa Depression is in the South Tianshan Piedmont region of the northern Tarim Basin, which is the main battlefield of the Tarim Basin oil and gas exploration in the recent years. The research team led by The China University of Petroleum professor and doctoral tutor Tang Liangjie wrote "Tectonic Evolution of the Western Qiulitage Tectonic Belt in Mesozoic and Cenozoic, Kuqa Depression" on the basis of the National Natural Science Fund Project and the National "973" Program research. Two geologic profiles are restored according to balanced section theory, with two wells’ subsidence history analysis, and reached on the mesozoic-cenozoic Characteristics of Tectonic Evolution of the belt, which is of important guiding significance for the next step of the oil and gas exploration.
A year’s plan stars with spring. We sow hope in the spring, and hope the readers of the Journal as always give more care and support and more valuable advice to help improve our work. Let us work together to make the Journal of the Southwest Petroleum University even better!
