【摘要】：为提高企业在施工作业过程中生产效率,通过改善作业技术手段达到节约成本、提高效能的最终目的,促进企业的健康、快速、可持续发展,本次针对本企业的主力作业区域开展课题的研究工作。本文对在辽河油区从事深探井钻井作业过程中出现的各种复杂情况,从地层的客观条件、复杂情况产生的原因进行梳理、总结与分析,利用所学的知识结合专业特点确定新的施工作业技术思路和研究方向。该项目从解决防塌、防漏堵漏、改善润滑性及提高钻速等5个方面的问题入手,分别制定了侧重点不同的5个钻井液技术方案。在通用技术方案的基础上,针对不同区域施工难点分别相对固化了与各作业区域相配伍的钻井液体系。通过在实验室内的一系列工作筛选出能够适用于该地区作业的技术模板。最终经过现场单井试用和大规模推广试用两个阶段的工作对实验室内形成的实验结果进行验证和完善,确定了适合辽河油区深探井施工的、具有较高安全保障的钻井液体系与技术模板。通过本次研究成果的推广,本企业在辽河油区施工的生产效率得到了显著提高,单井生产成本得到了有效控制,达到了预期的效果。
[Abstract]:In order to improve the production efficiency of the enterprise in the process of construction operation, the ultimate goal of saving cost and improving efficiency is achieved by means of improving the operation technology, and the healthy, rapid and sustainable development of the enterprise is promoted. This work is aimed at the main operation area of this enterprise to carry out the research work of the subject. In this paper, all kinds of complicated situations occurred in the deep exploration well drilling operation in Liaohe oil area are sorted out, summarized and analyzed from the objective conditions of the formation and the causes of the complicated conditions. Make use of the knowledge learned and professional characteristics to determine the new construction operation technical thinking and research direction. In order to solve the problems of anti-sloughing, leakage prevention, improvement of lubricity and drilling rate, five drilling fluid technical schemes with different emphasis have been worked out in this project. On the basis of the general technical scheme, the drilling fluid system compatible with each working area has been relatively solidified according to the difficulties of construction in different areas. Technical templates suitable for operation in the area were screened through a series of tasks in the laboratory. Finally, through two stages of field single-well trial and large-scale popularization and trial, the experimental results formed in the laboratory are verified and perfected, which is suitable for the construction of deep exploration wells in Liaohe oil area. Drilling fluid system and technical template with high safety guarantee. Through the popularization of the research results, the production efficiency of the enterprise in Liaohe oil area has been significantly improved, the production cost of single well has been effectively controlled, and the expected effect has been achieved.
