| Abstract: | Based on the analysis of compression pore evolution, fracture, mineral component and the study of effect of diagenesis stages on reservoirs, the physical base of effects of diagenesis stages on reservoirs is discussed by applying well logging information. These results indicate that the effect of diagenetic stages on reservoirs are available by means of well log information. The method include as fellows:(1) In Early diagenesis stage, the porosity and lithology well logging data are applied to analysis compression curve, and to determine the compression area. (2) In Middle diagenetic stage, first, it is used to analysis the secondary pores by means of acoustic porosity and density-neutron porosity. The crossplot technique is used to determine mineral component and the types of cementation and replacement. The mud content is able to be determined by means of mud indication log. The clay mineral can be studied by using the gamma spectrometry, special thorium, and potassium content. (3) In the late diagenetic stage, the distributions of secondary pore, fracture, grain component, grain content and clay mineral can be researched by logging. The above methods are tested in Th-Ha basin and show an ideal effect. |
