摘要
针对国内外传统油气井释放水泥工具所存在的弊端,基于井下电动工具的设计原理,创新性地研制出了一套新型井下电控水泥释放工具.详细介绍了该工具的结构组成和工作原理,重点对工具动作部件进行了力学分析,探究了井斜、温度、压力及井液性质对工具开启的影响,所研制的井下电控水泥释放工具外径为73 mm,长度为1 400 mm,可根据不同施工井况,通过变扣灵活配备不同规格的储灰筒.高压地面试验和现场施工试验分别验证了工具耐高温高压性能以及倒灰作业施工的可行性.可为油气井封堵作业的安全施工提供更高效可行的技术支撑.
Abstract
In response to the shortcomings of traditional underground ash removal tools at home and abroad,a new type of underground electrically controlled cement release tool has been innovatively developed based on the working principle of underground electric tools.The structure and working principle of the tool have been described in detail,with emphasis on the mechanical analysis of the moving parts of the tool,and the effects of borehole inclination,temperature,pressure and borehole fluid properties on the opening of the tool have been studied.The rationality and reliability of the design were fully verified by high-temperature,high-pressure underground tests and on-site construction tests.Research experiments have shown that the developed underground electrically controlled cement release tool has an outer diameter of 73 mm and a length of 1 400 mm,and can be flexibly equipped with different specifications of ash storage cylinders according to different construction well conditions.Ground tests and on-site construction tests have verified the high temperature and high pressure resistance performance of the tool and the feasibility of ash dumping operations,respectively.The above conclusions can provide more efficient and feasible technical support for the safe construction of oil and gas well plugging operations.
