齐家北地区FⅠ1油层成岩特征及有利储层预测
DIAGENESIS FEATURES AND FAVORABLE RESERVOIR PREDITION OF F Ⅰ 1 OIL LAYER IN NORTH OIJIA
摘要
Abstract
The numerical simulations are conducted respectively for individual diagenesis in these diagenesis field by the following chosen parameters: paleotemperature, Ro, self-quartz & turbid zeolite volumetric fractions and the relative volumetric fractions of smectite. At the same time, a diagenetic index (ID) that can comprehensively reflect the diagenesis intensity and facilitates dividing the facieses of diagenesis is constituted by the combination of these parameters. The complex analyses show that F I 1 oil layer of Gu708 Block of North Qijia can be classified as diagenesis period A I , A II and B, mainly distributed in A II Period. The diagenesis in A II Period is beneficial to the developments of primary and secondary porosities, three main controlling factors such as sedimentary and diagenetic facieses and hydrocarbon charge totally determine the evolution of the physical properties of the reservoir, the sedimentary facies dominates the development and evoluLion of the primary porosity, the other two factors controls the development of the secondary porosity. Finally the favorable blocks of the physical properties of the reservoir in F I 1 oil layer in Gu708 Block are pointed oul.关键词
