Milankovitch cycle is the manifestation of Milankovitch effect in the stratigraphic record. Its time property is an effective means to divide and constrast the high-resolution strata. In order to reveal the differences of Milankovitch information preserved among different stratigraphic units, enrich stratigraphic theory, especially cyclostratigraphic theory, Milankovitch features were extracted by means of the Extreme Mode method of one-dimensional Continuous Wavelet Transform from related strata based on the GR well logging data of 38 wells in Jiyang Depression Zone, and the thickness of the cyclothems recognized corresponding to the precession, obliquity and eccentricity was calculated respectively and their fluctuation was also analyzed. The results show that, in the study area, there widely exists Milankovitch information in several stratigraphic intervals. Among them, the thickness of the precession cyclothem varies in ranges of 3.4-17.1 m, 8.6-19.0 m and 7-11 m in Early Paleozoic (∈-O), Late Paleozoic (C-P) and Cenozoic (E-N) correspondingly. And among them, 13m, 14m and 10m cycles are the principal ones; the thickness of the obliquity cyclothem, in the same way, 7.2-27.8 m, 19.5-39.2 m and 14-26 m, with 27 m, 26 m and 21 m as principal cycles while eccentricities are 20.3-64.6 m, 37.2-75.1m and 40-60 m, and 60 m, 74 m and 51m being principal ones. The thickness of Milankovitch cyclothem in Mesozoic varies in ranges of 3.2-21.4 m, 6.2-42.8 m and 15.4-108.6 m, corresponding to precession, obliquity, and eccentricity respectively, with no obvious principal cycle. A conclusion can be drawn that the fluctuation of the thickness of Milankovitch cyclothem tends to strengthen with the aging of the geological intervals from Cenozoic (E-N), Late Paleozoic (C-P) to Early Paleozoic (∈-O), that is, the stability of Milankovitch cycle information preserved in the older strata is deteriorated more by the following geological events. The strongest fluctuation of the thickness of Milankovitch cyclothem in Mesozoic was probably resulted from the stronger sedimentary environment differentiation caused by the active tectonics. Furthermore, the accumulation rate was calculated and explained for different geological intervals in terms of the thickness of principal cyclethom.

Basing on the operation data of 4.0 ×104 t/a CO2 capture and purification system from power plant flus gas, the capture process and technisime was analyzed and a general renewable energy calculation model was conducted. The influences of absorber performance, absorbent characteristic and heat exchanger's ability on renewable energy consumption was analyzed respectively. Furthermore, the comparison of renewable energy between MEA and DEA along with the variation of absorbent concentration and absorbent regeneration level was conducted. Results indicate that the absorbent renewable energy consumption could be reduced by using of increasing absorbent concentration, proper blending absorbents type and content and enhancing the heat exchanger ability.

With the purpose of investigating the thermal efficiency of steam-injection boiler, the thermal efficiency calculation model was built. Basing on the measured data from Xianhe oil production plant in Shengli oil filed, both energy efficiency and exergy efficiency were calculated and the boiler operation state was analyzed. Moreover, the influences of smoke temperature, excess air ratio and steam quality on energy efficiency and exergy efficiency of steam-injection boiler was also analyzed, and the boiler operation parameters was optimized. © 2011 IEEE.
