中国石油天然气股份有限公司成立5年来,上游业务勘探开发取得了骄人的成绩,2004年实现了新增探明地质储量第八次超过5亿吨,新增控制石油地质储量创历史最高水平,新增天然气三级储量保持较高增长,原油产量连续三年“箭头向上”,天然气产量继续保持两位数增长。然而,众所周知,经过几十年的勘探开发,随着我国勘探总体程度的加深,无论是新区还是老区,油气藏类型日趋复杂,勘探开发难度日益加大。尤其是一部分老油田,储采失衡,已进入“三高”开发阶段,易采区块资源基本采尽,稳产增产难度加大。作为中国石油最大的业务板块,中国石油勘探与生产分公司的各项工作乃是关系到中国石油乃至集团公司实现持续有效较快发展战略目标的关键。面对一系列挑战,中国石油勘探与生产分公司总经理胡文瑞秉持求真务实的理念,作出了将调查研究作为重要工作手段的决定。他认为,理论与技术的不断创新,是企业得以持续发展的灵魂。而创新源泉则基于调查研究,没有调查研究就没有决策权。中国石油勘探与生产分公司自2003年开始,坚持以“调查研究、创新典型”为主线,组织力量开展了勘探、开发、地面建设、钻井工程四个方面的重点调研,并在近两年的时间里,撰写了14篇具有较强典型性、先进性和示范性的调查报告。这些调研报告的出台,不仅是对各油气田成功经验的一次总结,更体现的是一种科学严谨、求真务实的态度,是一种奋发进取、开拓创新的精神,是一种开放的思维和前瞻的远见。为了让业界共享中国石油勘探与生产分公司这些极具推广价值和指导意义的典型经验,促进各油气田相互学习促进,引领和推动油气勘探开发领域实现新的更大突破,本刊将连续刊发这一系列调查报告,以飨读者。 In the five years since its establishment, China National Petroleum Corporation (CNPC) has achieved remarkable success in its exploration and development of its upstream business. In 2004, it achieved more than 500 million tons of new proved geological reserves and newly increased controlled petroleum geological reserves to a record high. The newly increased reserves of tertiary natural gas maintained its high growth. Crude oil output rose for “three consecutive years” and natural gas output maintained double-digit growth. However, as we all know, after several decades of exploration and development, with the deepening of the overall exploration in our country, the types of oil and gas reservoirs have become increasingly complex, both in new and old areas, and the exploration and development have become more and more difficult. In particular, part of the old oilfields have an imbalance between storage and production and have entered the development stage of the “three highs”. Resources in the easily-accessible mining blocks have basically been exhausted, making it more and more difficult to increase production steadily. As the largest business unit of PetroChina, all the work of PetroChina’s Exploration and Production Branch is the key to PetroChina’s and even group companies’ strategic goals of achieving sustained, effective and rapid development. Faced with a series of challenges, Hu Wenrui, general manager of PetroChina Exploration and Production Company, upheld the concept of seeking truth and being pragmatic, and made a decision to make investigation and study an important means of work. He believes that the continuous innovation of theory and technology is the soul of sustainable development of enterprises. The source of innovation is based on the investigation and study, there is no research without the right to decision-making. Since 2003, PetroChina Exploration and Production Branch has adhered to the principle of “research, innovation and model” as the main line and organized forces to carry out key investigations in four aspects of exploration, development, ground construction and drilling engineering. In the past two years During the time, he wrote 14 highly typical, advanced and exemplary investigation reports. The introduction of these research reports is not only a summary of the successful experiences of all oil and gas fields, but also a rigorous and pragmatic approach that is rigorous and innovative. It is an open mind and an open mind. Forward-looking vision. In order to allow the industry to share these typical experiences of great promotion value and guiding significance from the Exploration and Production Branch of CNPC, and promote mutual learning among oil and gas fields and to lead and promote new breakthroughs in the field of oil and gas exploration and development, this issue will be published continuously This series of survey reports to readers.
