＜正＞This report aims at traits of national enterprises, and presents a set of integrative system about advance warning synthetic indexes of management crisis. This system reflects enterprise management process and result from financial indexes and non-financial indexes. Two kinds of indexes not only link to quantitative and non-quantitative indexes but also integrate experts’ experience and support of impersonal data. With the Delphi Method, AHP Method and Fuzzy Evaluation Method, this system can evaluate the management operations of company ,thus attaining the purpose that warning the management crisis in advance.

Diagenesis of clastic rock and hydrocarbon generating capacity are closely related with diagenetic *** on diagenetic evolution,reservoir diagenetic stages prediction method is proposed through making a contrastive study of simulation results and test results using core measurement *** essence of this method is illustrated and its effectiveness is demonstrated using Ed2 clastic sandstones in the west of Bozhong sag,Bohai Bay Basin,*** of paleo temperature(T),vitrinite reflectivity(Ro%)and the proportion of smectite in illite/smectite interstratified minerals(I/S-S%)indicate that there are there types of diagenetic stages in the study area,including early diagenetic stage B,middle diagenetic stage A1 and middle diagenetic stage *** only considering T index for diagenetic stages prediction,the simulation results are more conservative than measured data with some situations,and the simulation result using Ro%for diagenetic prediction is less than measured data in some *** I/S-S%is used,the two situations above both *** depth,temperature,time duration,pressure and some chemical variables can change synchronously or asynchronously,it is difficult to attribute with certainty the parameters that affect the apparent diagenetic stages evolution *** stage variations can be significantly different in different parts of one sedimentary basin.A synthetic indexes method considering T,Ro%,I/S-S%to predict its distribution,and the simulation result has proved that the reliability of the model has greatly improved.
