12月24日,大庆油田第三采油厂工程技术大队研发的机采井作业井下防喷技术通过油田采油工程系统项目验收评定。截至当日,这一系列技术申报2项国家专利,应用创效831多万元,较好解决了油田机采井作业防喷难题,为打造绿色油田提供强有力的技术支撑。大庆油田机采井进行起下管柱和检泵等作业过程中,经常遇到地层压力较高和采出液从井下喷出的问题,不仅威胁作业工人的施工安全,而且易造成污染。仅以萨北油田为例,年平均压井作业300井次之多。此外,利用泥浆压井费用较高,作业效率较低且容易对油层和
December 24, Daqing Oilfield Third Production Plant Engineering and Technology Research and Development team of production wells operating wellbore blowout prevention technology through the oil field engineering project acceptance evaluation. As of the date of this series of technologies to declare the two national patents, the application of more than 831 million yuan, a better solution to the oil well drilling machine blowout problem, to create a green field to provide strong technical support. In Daqing Oilfield, the production wells are used for pipe stringing and pump detection. In the process of operation, the high formation pressure and the eduction of produced liquid from the well often threaten the construction workers’ safety and cause pollution easily. Taking the Saabei oilfield as an example, the annual average well killing operation is as many as 300 wells. In addition, the cost of using mud-killing is high, making operations less efficient and easier for reservoirs and reservoirs
