松辽盆地英台地区北部沉积旋回模式的马尔柯夫链模拟

MARKOV CHAINS SIMULATION ON THE SEDIMENTARY CYCLIC IN NORTH YINGTAI AREA SONGLIAO BASIN

本文从马尔柯夫链原理出发,在系统地统计松辽盆地英台地区北部9口探井所揭示的地层基础上,结合探区的地质特征,对该区的沉积模式进行了极限概率、差值矩阵、置换、熵和沉积旋回最优分解等综合分析。实际应用表明,应用马氏理论所揭示的沉积旋回模式,其理论计算方法可行,成果可靠,综合分析的结论与地质结论完全一致。

<ABSTRACT>: Starting from Markov chains principles, this paper, based on the core information revealed by 9 Wells in the north of yingtai in Songliao basin, systematically counts, up all rock types and their transitions in geological terms.Combined with the geological features, the comprehensive analyses of the sedimentation model of this area, the limit probability analysis, the difference matrix analysis, the substitutility analysis, the entopy analysis and sedimentary cycle, as well as tne optimum decomposition analysis have been made.The actual applications Indicate that the cyclicpa tterns disclosed by Markov chains theory have practicable calculating procedu-res and credible results, whereas the geological conclusions and the results of the comprehensive analyses are identical.
