Abstract

In order to fulfill the present need for downhole lifting pumps in various cutting-edge drilling techniques, a double jet pump is ingeniously devised. The internal three-dimensional characteristics of this pump are utilized to optimize its structural parameters through the flow field simulation method. Extensive evaluations are conducted to assess the alterations in jet performance under different parameters, including area ratios, throat lengths, nozzle exit positions, and nozzle area ratios. The pivotal structural parameters of the double jet pump are optimized as follows: area ratio $m_{a} = 0.22$ , throat length $L_{h} = 84.5$ mm, nozzle exit position $L_{c} = 6.76$ mm, and nozzle area ratio $m_{b} = 0.3$ . Furthermore, an experimental platform is meticulously erected to validate the principles of the double jet pump and to analyze its jet performance. This ascertains the feasibility of the double jet pump and validates the accuracy of the simulation and analysis results. This device can be effectively employed in the oil and gas production characterized by a high sand content extraction.

研究石油和天然气生产中用于高含沙量提取的双喷射泵的工作特性

为了满足目前各种尖端钻井技术对井下提升泵的需求，我们巧妙地设计了一种双喷射泵。利用该泵的内部三维特性，通过流场模拟方法对其结构参数进行了优化。对不同参数（包括面积比、喉管长度、喷嘴出口位置和喷嘴面积比）下的射流性能变化进行了广泛的评估。双喷射泵的关键结构参数优化如下：面积比 ma=0.22，喉管长度 Lh=84.5毫米，喷嘴出口位置 Lc=6.76毫米，喷嘴面积比 mb=0.3。此外，还精心搭建了一个实验平台，以验证双射流泵的原理并分析其射流性能。这确定了双喷射泵的可行性，并验证了模拟和分析结果的准确性。该装置可有效用于含沙量较高的石油和天然气生产。

期刊介绍： Flow Measurement and Instrumentation is dedicated to disseminating the latest research results on all aspects of flow measurement, in both closed conduits and open channels. The design of flow measurement systems involves a wide variety of multidisciplinary activities including modelling the flow sensor, the fluid flow and the sensor/fluid interactions through the use of computation techniques; the development of advanced transducer systems and their associated signal processing and the laboratory and field assessment of the overall system under ideal and disturbed conditions. FMI is the essential forum for critical information exchange, and contributions are particularly encouraged in the following areas of interest: Modelling: the application of mathematical and computational modelling to the interaction of fluid dynamics with flowmeters, including flowmeter behaviour, improved flowmeter design and installation problems. Application of CAD/CAE techniques to flowmeter modelling are eligible. Design and development: the detailed design of the flowmeter head and/or signal processing aspects of novel flowmeters. Emphasis is given to papers identifying new sensor configurations, multisensor flow measurement systems, non-intrusive flow metering techniques and the application of microelectronic techniques in smart or intelligent systems. Calibration techniques: including descriptions of new or existing calibration facilities and techniques, calibration data from different flowmeter types, and calibration intercomparison data from different laboratories. Installation effect data: dealing with the effects of non-ideal flow conditions on flowmeters. Papers combining a theoretical understanding of flowmeter behaviour with experimental work are particularly welcome.
