Description
技术领域technical field
本发明涉及一种涡街流量计，具体涉及一种适用于油水井井下的涡街流量计。The invention relates to a vortex flowmeter, in particular to a vortex flowmeter suitable for downhole oil and water wells.
背景技术Background technique
随着油田开发的深入，注入井和采出井层数逐年增加，其分层测试的难度也逐年增大，测试工作量明显提高。提高油田分层测试技术，能有效的改善注入井和采出井的开发效果，为进一步选择合理的采油工艺措施，为油田采油方案提供依据。With the deepening of oilfield development, the number of layers of injection wells and production wells has increased year by year, and the difficulty of layer-by-layer testing has also increased year by year, and the testing workload has increased significantly. Improving oilfield layering test technology can effectively improve the development effect of injection wells and production wells, provide a basis for further selection of reasonable oil recovery technology measures, and oil recovery plans.
常用的井下流量计包括以下几种：Commonly used downhole flowmeters include the following:
电磁流量计：测量精度受被测介质导电率影响，且感应电极易被油污覆盖从而影响测试效果；Electromagnetic flowmeter: The measurement accuracy is affected by the conductivity of the measured medium, and the sensing electrode is easily covered by oil, which affects the test effect;
超声波流量计：只能用于测量清洁的液体和气体，井下介质油水混合不均匀从而影响测试效果；Ultrasonic flowmeter: It can only be used to measure clean liquid and gas, and the uneven mixing of oil and water in the downhole medium will affect the test effect;
涡轮流量计：测量精度受油污粘度影响，涡轮易被污垢铁锈卡死，导致测量不准，影响测试效果。Turbine flowmeter: The measurement accuracy is affected by the viscosity of oil, and the turbine is easily stuck by dirt and rust, resulting in inaccurate measurement and affecting the test effect.
井下流量计对液体流量测试的准确性直接影响了采油效果的好坏，因此针对高精度井下流量测调系统进行了开发研究。因此，选用更具有井下工况适用性能的涡街流量计作为油田井下的流量测试单元。The accuracy of the downhole flowmeter for liquid flow testing directly affects the oil recovery effect, so the development and research of the high-precision downhole flow measurement and adjustment system was carried out. Therefore, the vortex flowmeter, which is more suitable for downhole working conditions, is selected as the flow test unit in the downhole of the oil field.
综上，现有的用于油水井井下的流量计由于受到井下环境的影响，检测传感器流量计使用寿命短、不直接接触被测介质，导致流量计测试效果不准确。In summary, due to the influence of the downhole environment, the existing flowmeters used for downhole oil and water wells have a short service life of the detection sensor flowmeter and do not directly contact the measured medium, resulting in inaccurate test results of the flowmeter.
