摘要 大斜度井测试同直井测试相比有较大的区别。在大斜度井进行地层测试时,常遇到封隔器漏失、在设计压力下N阀和循环阀打不开等问题。以巴基斯坦M-2斜井为例,对测试工具在斜井段的受力情况进行分析,对N阀和循环阀充氮压力值进行精确计算,在测试设计和操作上做出相应的调整,则大斜度井测试就会和直井测试一样取得较高的测试成功率。 The test to high deviated wells has bigger difference compared with the vertical Wells. During well test in high Angle Wells,problems of leakage of packer and not to be opened of N valve and circulating valve under design pressure are often encountered. Taking Pakistan M-2 inclined well as an example,through analyzing the force to the test tool in the inclined section,precisely calculation to filling nitrogen pressure value of N valve and circulating valve,and corresponding adjust of the test design and the operation,a much high success rate of test for the high deviated wells can be got as the vertical wells.
