【摘要】：世界海洋石油资源量占全球石油资源总量的34%,全球海洋石油蕴藏量约1000多亿吨,其中已探明的储量约为380亿吨。随着人类对海洋油气开发的认知不断提升,以及技术进步导致海洋油气开采成本大幅下降,全球油气开采将进入海洋时代。全球油气消费稳步增长,中国需求增长迅速。尽管海洋资源量巨大,但是目前由于深海勘采技术及实际控制等原因,中国仍以近海石油勘采为主,90%以上的海洋石油产量来自浅海。因此,国内海洋油气生产还主要集中在近海浅海区域,对近海浅海区域油田进行的维护和进一步的开发,是当前海洋石油必须牢牢把握的重点。浅海油田的开发和维护是以导管架平台作为依托的生产方式,导管架的顺利建造关系到油田的顺利生产,关系到国家的能源安全。本文以WZ12-1B平台外挂式导管架作为研究对象,针对特定条件下的导管架翻转方式进行研究,研究内容如下：(1)对典型导管架装船方式进行研究,针对本课题导管架的特点,采取新的装船方式；(2)利用海洋平台结构设计与分析软件SACS对导管架翻转过程关键状态进行力学分析；(3)对翻转工装进行设计、校核,对吊机和钢丝绳进行校核与选型；(4)对导管架翻转及装船方式进行现场施工,完成装船作业。通过对WZ12-1B平台导管架翻转方式的研究和应用实施,对生产任务的合理安排进行了有效的创新,为导管架的建造方式和装船方式的提供了新的思路。
[Abstract]:The world offshore oil resources account for 34 percent of the world's total oil resources. The global offshore oil reserves are about 100 billion tons, of which the proven reserves are about 38 billion tons. With the increasing awareness of offshore oil and gas exploitation and the decline of offshore oil and gas exploitation cost due to technological progress, global oil and gas exploitation will enter the ocean age. Global oil and gas consumption has steadily increased, while China's demand has grown rapidly. Despite the huge amount of marine resources, at present, because of the deep-sea exploration and mining technology and practical control, more than 90% of offshore oil production in China is mainly offshore oil exploration and production from shallow water. Therefore, the domestic offshore oil and gas production is mainly concentrated in the offshore shallow area, the maintenance and further development of offshore oil field is the key point that must be firmly grasped at present. The development and maintenance of shallow water oil field is a production mode based on jacket platform. The successful construction of jacket is related to the smooth production of oil field and national energy security. In this paper, the external jacket of WZ12-1B platform is taken as the research object, and the reverse mode of jacket under specific conditions is studied. The research contents are as follows: 1) the typical jacket loading mode is studied, and the characteristics of the jacket in this subject are discussed. A new loading method is adopted: the structural design and analysis software SACS of offshore platform is used to carry out mechanical analysis on the key state of jacket turning process. (3) the turning tooling is designed and checked. The crane and wire rope are checked and selected. (4) to carry out on-site construction on the way of jacket turning and loading, and finish the loading operation. Through the research and application of the WZ12-1B platform jacket reversal mode, the reasonable arrangement of production tasks is effectively innovated, which provides a new idea for the construction mode and loading mode of the jacket.
