摘　　要：分层取样测试器通过选择性封隔地层,进行预测试,获取完整的不稳定试井曲线,可测得每个小层的地层静止压力、有效渗透率、污染系数等动态特性参数;该测试器可测试多个流量下其对应的稳定地层流动压力,并可获取地层流体真实样品,能够实时定量各小层在不同地层流动压力下的流体相态、流体成份和各流体体积流量,提前完成油气层产量定量测试。和普通试井相比, 测试时间短,操作简单,可节约油气资源,提高地层测试质量。分层取样测试器在纯油层和干气层中的应用效果良好。By isolating layers selectively,' Multi-Layer Sampling Tester can pretest formation and obtain integrated pressure transient curve, thus, estimate dynamic parameters of each layer, such as: formation static pressure, effective permeability and damage factor, etc. the apparatus also can complete deliverability test, measure every flow rate and its corresponding steady flow pressure, obtain true formation fluid samples, get fluid phase, fluid component and flow rate of each layer at different flow pressure real-time, and complete quantitative output test in advance. Compared with common well test, the apparatus costs very short time and are easy to operate, so can save lots of gas and oil resources and raise testing quality. All these characteristics make the apparatuses appropriate to use in gas-layer and oil-layer deliverability test in down-hole condition.
