渤海油田深井深层防漏堵漏技术策略研究

Research on the technical strategy of leakage prevention and plugging in thedeep well and deep formation of Bohai Oilfield

通过分析渤海油田近三年来漏失事件的漏失程度及类型,从工程角度提出渤海深井深层防漏技术策略和堵漏工艺选择策略,针对渤海深井深层漏失情况,从工程角度对漏失程度及类型进行统计分析,并结合现场情况和堵漏技术,提出渤海深井深层防漏技术和工艺选择策略,以提高钻前避漏的有效性和堵漏工艺的高效性,给海上油气田勘探开发提供一种安全、经济和高效新的思路。

Based on the analysis of the leakage degree and type of leakage events in Bohai oilfield in recent three years,this paper proposes the deep-layer leakage prevention technology strategy and plugging process selection strategy of Bohai deep well from the engineering perspective.According to the deep-layer leakage situation of Bohai deep well,this paper makes a statistical analysis of the leakage degree and type from the engineering perspective,and combines the on-site situation and plugging technology to propose the deep-layer leakage prevention technology and process selection strategy of Bohai deep well.In order to improve the effectiveness of pre-drilling leakage avoidance and high efficiency of plugging technology,it provides a safe,economic and efficient new idea for offshore oil and gasfield exploration and development..
