Introduced are the surface system and downhole tools for screw pump well and its testing technologies. In order to carry out production profile testing for screw pump well, a new type of production profile logging tool is designed. Presented are the structure, characteristics, main technical specifications and principle of the logging tool. The tool adopts flexible join structure, and it distributes 5 measured parameters including temperature, pressure, casing collar location, flow rate and water hold-up into multi-tool string. So it can passes through screw pump well mouth and the test channel easily. The bending part of the tool has good flexibility and high load pressure with special manufactural technique. It can withstand high temperature and high pressure as well. The measurement part for water hold-up uses 2 different measure patterns: resistance pattern or flow-by pattern for different testing fluids, and this makes the measurement range enlarged and the accuracy increased as well. Practical application of 2 wells in Daqing oilfield shows good result, and it is proved that the combination logging tool has an important role in the dynamic monitoring of screw pump well.
