The highest heat transfer coefficient for air flowing in the nine 3-D IFT with staggered arrangement fins is No9 tube. In the turbulent region, the heat transfer coefficient of No9 tube is a factor of 10.36 compared with smooth tube, and its thermodynamic performance coefficient is as high as 6.49; The average Nusselt number in the most superior 3-D IFT with staggered arrangement can be increased by about 1.04 times in the laminar flow, and 6.38 times in the transitional flow as compared with that in the smooth tube. The friction factor between fluid and tube wall can be 0.96 times in laminar flow, and 12.68 times in transitional flow as compared with that inside the smooth tube.

The suitability of the different processes was analyzed by observing the weld appearance,studying the microstructure and measuring the mechanical properties of the joint.The results show that a favorable weld can be obtained under the suitable parameters by laser beam welding or tungsten inert gas welding with filler metal.The TIG welded joint has a wider HAZ,and the laser welde...

试验结果表明：在工艺参数合适的条件下，加焊丝TIG焊和激光焊均能获得成形较好的焊接接头；TIG焊接头热影响区较宽，焊缝深宽比小，而激光焊时热影响区不明显，焊缝深宽比大；两种焊接方法所获得的焊缝区组织均为均匀的等轴晶，但激光焊时焊缝组织更细，从而使接头抗拉强度大幅度提高，达到母材的94%左右。

Firstly, with the analysis of electric characteristics of a condensate gas reservoir, we find that there are some differences between Tri\|porosity logging amplitude, Deep Investigation Laterolog, Shallow Investigation Laterolog, and Microlaterolog, etc; secondly, in view of the feature of the condensate gas reservoir, the log interpretation model is built on the basis of the correlation of four reservoir parameters, and the reservoir grade scale is completed using conventional logging techniques combined with cross plot technique and the result of well testing; finally, according to the feature of Qiketai Formation and Sanjianfang Formation in the Hongtai oil field, we set up the reservoir classification criteria and divide the reservoir parameters into four types.
