【摘要】：地面测试是在动态条件下检查油藏的一种常规测试技术,决定油藏生产能力和油藏物性。在如今的油气井测试计量过程中,三相分离器地面测试技术的应用越来越广泛。伴随着油气田的深入开发,含硫油气井,甚至高含硫油气井的测试计量工作也逐渐的开展起来。本文介绍了三相分离器的性能、工作原理及其使用现状,开展了针对高含硫井地面测试工艺的流程设计、设备材质的选择以及气产量计算公式的选择。由于硫化氢气体剧毒、强腐蚀等特殊属性,对使用三相分离器进行地面测试计量工作时的设备及相关附属设备设施要求不同于不含硫井所使用的设备。为了确保高含硫井测试计量工作的连续性,准确性以及安全性,结合现场生产的实际情况,对常用的三相分离器测试流程、设备进行改造,并进行了现场试验,对实验获得数据进行了总结与分析。对项目完成后的总体效果进行了评述。
[Abstract]:Surface testing is a conventional testing technique for checking reservoirs under dynamic conditions, which determines reservoir productivity and reservoir physical properties. In the process of oil and gas well measurement, the surface test technology of three-phase separator is more and more widely used. With the further development of oil and gas fields, the testing and metering of sulfur-bearing oil and gas wells, even high-sulfur oil and gas wells, has been carried out gradually. In this paper, the performance, working principle and application status of three-phase separator are introduced. The design of surface test process, the selection of equipment material and the selection of calculating formula of gas production are carried out. Due to the special properties of hydrogen sulfide gas such as high toxicity and strong corrosion, the requirements of equipment and related ancillary facilities for surface testing and metering with three-phase separators are different from those used in non-sulfur wells. In order to ensure the continuity, accuracy and safety of the testing and metering work of high sulfur containing wells, combined with the actual situation of field production, the test flow and equipment of the commonly used three-phase separator were reformed, and the field tests were carried out. The experimental data are summarized and analyzed. The overall effect after the completion of the project is reviewed.
