一、概述 地层测试器是及时评估油气井生产层的潜在能力的有效工具。目前许多国家已普遍采用它来对油气井进行测试。地层测试器用于钻井过程中的测试叫做中途测试,用于完井后的测试叫做套管测试。我国曾在江汉、四川等地少数裸眼井中进行过中途测试,测试工具是封隔器加玻璃接头,由于工具陈旧,工艺水平落后,不能对测试层作出定量分析,所以未能推广使 I. INTRODUCTION The formation tester is an effective tool for evaluating the potential capabilities of the production well in time. At present, it is widely used in many countries to test oil and gas wells. Formation Tester The test used during drilling is called midway test, and the test after completion is called casing test. In our country, Jianghan, Sichuan and other places a few open-hole wells in the mid-test, the test tool is a packer plus glass joints, due to outdated tools, the level of technology behind the test layer can not be quantitative analysis, it failed to promote
