With the complex of borehole structure, the well bore is also more and more deeper and smaller, and equipment and technical needs matching slim hole well becomes more and more bigger. The sbm hole testing tool belongs to full-bore pressure controlled testing tools, which is operated by annulus pressure. The operation is simple and annulus pressure need not to keep, reducing the possibility of incorrect operation caused by packer and casing damage to complete a variety of comprehensive testing technique.

Based on statistics to the applied well test technologies in Jidong oilfield in recent years, the problems existing in the test process are analyzed in-depth. According to supporting condition of the existing test tools, combined with field example of Nanpu XX well, test process optimization is used to effectively improve the targeted and scientific property of operation scheme, which forms a set of well test technology series under different well conditions to promote the further development of the well test technology to exploration and development in Jidong oilfield. ©, 2014, Well Testing.

The integrated technology of oil test and well test is that makes true of three processes of "perforation, well test, flow "as one test string to complete a number of oil testing operations. The integrated of " perforation , well test and jet pump , perforation, well test -and nitrogen gas lift flow " are introduced in Jidong Oilfield. At present, the integration technology of MFE tools, STV tools and negative pressure testing valve series is widely used, combining with advantages of the deep perforation technology, well test, hydraulic jet pump technologies, obtaining the formation parameters meanwhile reducing the number of washing well, preventing the second formation pollution.
