Description
技术领域technical field
本实用新型涉及一种陆地油田注水配套设备，属于油气田开发技术领域。The utility model relates to a water injection matching equipment for an onshore oil field, which belongs to the technical field of oil and gas field development.
背景技术Background technique
小型配水间是一种用于分散井组或者边缘井组的一种小型配水器，其中包含注水自控仪、流量计以及相关闸阀等。配水支线进入配水间后，经过过滤器，通过不同的高压流量计向各个水井注水。为解决注水的集中分配提供了很好的基础，常见的有7井式、5井式、3井式等，为获得更高的采油质量与效率，各注水点的注水量须严格控制。但由于目前普遍的注水压力相当高，加之常规的电磁流量计本身误差精度不高，导致注水量的录取失真，甚至随着仪器的磨损造成泄压，为注水的管理和注水开发效果埋下了巨大的隐患。为此，高压流量计须间隔三个月标定一次，以保证其流量准确，目前所采用的方法大都是关闭进出口阀门，拆卸流量计并对其进行实验室校准，这种方法准确度较高，但会影响整个注水作业，且拆卸过程管道存水会弄湿配水间，不利于仪器和设备防腐的要求。因此有必要需要一种用于简单实用的误差测量装置。The small water distribution room is a small water distribution device for scattered well groups or marginal well groups, which includes automatic water injection control devices, flow meters and related gate valves. After the water distribution branch line enters the water distribution room, it passes through the filter and injects water into each well through different high-pressure flow meters. It provides a good foundation for solving the centralized distribution of water injection. The common types are 7-well, 5-well, and 3-well. In order to obtain higher oil production quality and efficiency, the water injection volume of each water injection point must be strictly controlled. However, due to the generally high water injection pressure at present, and the low error accuracy of the conventional electromagnetic flowmeter itself, the recording of the water injection volume is distorted, and even the pressure is released with the wear of the instrument, which has buried the water injection management and water injection development effect. Huge hidden danger. For this reason, the high-pressure flowmeter must be calibrated every three months to ensure its flow rate is accurate. Most of the methods currently used are to close the inlet and outlet valves, disassemble the flowmeter and perform laboratory calibration on it. This method is more accurate. , but it will affect the entire water injection operation, and the water in the pipeline during the dismantling process will wet the water distribution room, which is not conducive to the anti-corrosion requirements of instruments and equipment. Therefore it is necessary to need a simple and practical error measuring device.
