摘要:
柱塞气举是一种高效的井下工艺技术，能够有效提高气井产量，解决常规井连续气举效果不佳的问题。在柱塞气举过程中，由于管柱与柱塞之间存在间隙，柱塞在速度、压力和气体滑脱等因素的作用下可能会发生液体漏失。为了提高柱塞气举的效率，准确评估柱塞的漏失量至关重要，而柱塞环隙含气率是评价柱塞漏失的关键参数。为此设计了一套基于图像处理的气泡检测方法,用来实现柱塞环隙截面含气率测定。通过采用高速摄像机对直径为60 mm的玻璃管柱内柱塞环隙气泡进行实时拍摄和图像采集，提出一种利用数字图像处理技术检测玻璃管柱内柱塞环隙截面含气率的方法。利用图像处理技术对图像进行梯度计算、形态学操作、边缘检测、二值化、连通域筛选和填充等处理得到截面含气率。最后与实验计算结果比较表明:该文方法测量得到的含气率与Hansan-Kabir方法计算得到的含气率误差在±15%以内，具有较高的测量精度和实用价值，为今后柱塞漏失量计算和柱塞环隙含气率的在线检测提供新的思路。
Abstract:
Plunger lift is an efficient downhole process technology that can effectively increase gas well production and address the poor performance of conventional continuous gas lifting. During the plunger lift process, due to the gap between the tubing and the plunger, the plunger may experience liquid leakage under the influence of factors such as velocity, pressure, and gas slip.To improve the efficiency of plunger gas lifting, accurately assessing the leakage of the plunger is crucial, and the gas content in the plunger annulus is a key parameter for evaluating plunger leakage. To achieve this, a bubble detection system based on image processing was designed to measure the cross-sectional gas volume fraction in the plunger annulus. A high-speed camera is used to capture real-time images and collect data on the bubbles in the plunger annulus within a 60mm diameter glass tube. A method is proposed to detect the cross-sectional gas volume fraction in the plunger annulus inside the glass tube using digital image processing technology. This involves gradient calculation, morphological operations, edge detection, binarization, connected domain filtering, and filling processes to determine the cross-sectional gas volume fraction. Finally, comparison with experimental calculations shows that the error in the gas volume fraction obtained by this method is within ±15% of the Hansan-Kabir method, indicating high measurement accuracy. This provides a new approach for future calculations of plunger leakage and online detection of gas volume fraction in plunger annuli.
