Long delays and poor real-time transmission are disadvantageous to well logging networks consisting of multiple subnets. In this paper, we proposed a time-driven transmission method （TDTM） to improve the efficiency and precision of logging networks. Using TDTM, we obtained well logging curves by fusing the depth acquired on the surface, and the data acquired in downhole instruments based on the synchronization timestamp. For the TDTM, the precision of time synchronization and the data fusion algorithm were two main factors influencing system errors. A piecewise fractal interpolation was proposed to fast fuse data in each interval of the logging curves. Intervals with similar characteristics in curves were extracted based on the change in the histogram of the interval. The TDTM is evaluated with a sonic curve, as an example. Experimental results showed that the fused data had little error, and the TDTM was effective and suitable for the logging networks.

Quenching and Partitioning (Q&P) steel is a new type ultrahigh strength steel with transformation induced plasticity (TRIP) effect. Uniaxial tensile experiments of the Q&P steel at room temperature were carried out to investigate the effects of sampling angle and strain rate on its mechanical properties. Experimental results show that the flow stress-strain curve, the hardening component n, the anisotropy coefficient through thickness r and the elongation of the Q&P steel are not sensitive to the sampling angle. However, the hardening component n and the elongation of the Q&P steel decrease with increasing the strain rate. Due to the Q&P steel with TRIP effect, when the strain rate greater, the deformation work will transform to the internal energy of specimen, and the TRIP effect of the Q&P steel will be inhibited, which results in less transformed retained austenite. X ray diffraction experiments were performed to verify it.
