摘　　要：BURUN油区因开采时间长,部分断层油藏枯竭,地层压力极低。油区初期使用第二代地层测试器,其预测试次数、速度、体积等设置不灵活,低渗透率地层和大压差导致这类仪器测压成功率低、压力资料超压严重。根据第三代电缆式地层测试器的设计原理,针对中低渗透率枯竭层的特征,研究了一套新型采集方法。该方法基于哈里伯顿公司的第三代电缆式地层测试器,并在油区获得成功应用。其中涉及电缆地层测试的思想和物理模型,为第三代电缆式地层测试器的研发和推广提供了思路。Due to the long extraction time,some fault reservoirs in the BURUN oil field have been depleted,resulting in extremely low formation pressure.In forepart of the project,second generation WFT tool is used.With nonadjustable pretest number,rate and volume,the low permeability intervals and big differential pressure caused a lot of matters for the tool,such as low success ration and supercharge.This article is based on the basic theory of the third generation formation tester,a new method of data acquisition has been developed,which successfully implemented with Halliburton RDT tools in the oil field.The operating principle and the diffusion model which are mentioned in the article provide theoretic guides for wireline industry.Provide ideas for the development and promotion of the third-generation wireline formation tester tools.
