【摘要】：某人工岛所在油田属于海上稠油油田,进入开发中、后期后,将以蒸汽吞吐方式进行开采。该海上油田开采方式,在国内外都尚属首次,对修井作业提出了更高的要求。通过文献查询及对海上、陆上服役机型进行调研,目前海洋修井机为海上修井作业的主要机型,但该机型一般是为导管架采油平台设计的,修井范围有限,且整机配套价格较高。由于某人工岛的油水井比较多,常规海洋修井机对于该岛修井作业的适用性将明显降低,且作业成本也将大幅增加。另外,陆上油田成熟的修井作业技术,也不能完全满足该油田海上修井作业的要求,对修井作业的安全、环保、井控及工艺技术等方面提出了更高的要求。本文从陆上、海上稠油油田的修井装备配套及修井作业技术现状出发,从中获取一定经验,进而针对某人工岛环境特点,分析和研究了某人工岛修井作业技术,包括修井机的选型、导轨式修井装备配套设施研究、管杆自动测量技术研究和修井作业工艺流程设计等内容。其中,导轨式修井装备配套设施研究,又包括井口管杆机械化输送系统、升高立管、BOP悬吊运移装置、高空操作起放装置、可调式喇叭管等内容。开展了陆地演装试验,在检验修井机及其配套设施等的性能、兼容性的基础上,提出了优化改进方案,通过联合调试,为后续登岛试运行提供了保障。在登岛修井作业时,升高立管、BOP悬吊运移装置、高空操作起放装置、可调式喇叭管等配套设施保障了安全作业,满足作业环境和施工工艺要求;井口管杆机械化输送系统、管杆自动测量及匹配优化系统提高了修井作业的自动化水平,降低了操作工人的劳动强度。通过对某人工岛井口槽双排密集布置方式及直线抽油机等岛面生产设施空间分布特点进行分析研究,采用HXJ135E轨道式修井设备、机械化配套设施及优化的洗井、冲砂等修井作业工艺,解决了某人工岛狭小空间内修井作业难题,提高了修井作业质量,对海上修井作业具有指导作用。
[Abstract]:An artificial island oil field belongs to offshore heavy oil field, which will be produced by steam huff and puff in the later stage of development. It is the first time at home and abroad that the offshore oil production mode has put forward higher requirements for workover operation. Through literature inquiry and investigation of offshore and onshore service models, at present, ocean workover machine is the main type of offshore workover operation, but this type is generally designed for jacket oil recovery platform, and the workover range is limited. And the complete set price is higher. Because there are many oil and water wells in a artificial island, the applicability of conventional ocean workover machines to the workover operation on the island will be obviously reduced, and the operating cost will be increased greatly. In addition, the mature workover technology in onshore oil fields can not fully meet the requirements of offshore workover operation in this oilfield, and puts forward higher requirements for the safety, environmental protection, well control and process technology of workover operation. In this paper, based on the status quo of workover equipment and workover technology in onshore and offshore heavy oil fields, some experiences are obtained, and then, according to the environmental characteristics of an artificial island, the workover operation technology of a artificial island is analyzed and studied. It includes the selection of workover machine, the research of supporting facilities of guideway workover equipment, the research of automatic measurement technology of pipe rod and the design of workover process flow. Among them, the research on the supporting facilities of guideway workover equipment also includes the mechanized conveying system of wellhead pipe rod, the suspended transportation device of raising riser and BOP, the high altitude operation lifting and releasing device, the adjustable horn pipe and so on. On the basis of testing the performance and compatibility of workover machine and its supporting facilities, an optimized and improved scheme is put forward. Through joint debugging, it provides a guarantee for the subsequent trial operation on the island. During the workover work on the island, the hoisting riser and BOP suspending and moving device, the high altitude operation lifting and releasing device, the adjustable horn pipe and other supporting facilities ensure the safe operation and meet the requirements of the working environment and the construction technology, and the mechanized conveying system of the wellhead pipe rod, The automatic measuring and matching optimization system of pipe rod improves the automation level of workover operation and reduces the labor intensity of operation workers. Based on the analysis and study of the spatial distribution characteristics of the island production facilities such as a manmade island wellhead groove with double rows and linear pumping units, HXJ135E track workover equipment, mechanized supporting facilities and optimized well washing are adopted. The workover operation technology of sand washing and other workover has solved the problem of workover operation in a small space of artificial island, improved the quality of workover operation, and has a guiding effect on offshore workover operation.
