摘要

针对河坝地区储层埋藏深、成岩作用强、非均质性严重、含气富集条件复杂等地质特点

对河坝地区进行了地层划分和对比、沉积相研究、储层基本特征分析、测井解释、储层预测、储层定量综合评价等研究

建立了河坝地区储层沉积模式

确定了储层的储集空间类型.预测了储层的空间展布、评价出有利储层发育区

形成了一套适用于河坝地区储层预测和综合评价方法。

Abstract

Reservoirs in Heba area are characterized by large burial depth

strong diagenesis

extreme heterogeneity

and complicated gas accumulation conditions.Based on stratigraphic division and correlation

study of sedimentary facies

analysis of basic features of reservoirs

logging interpretation

and reservoir prediction and quantitative evaluation in Heba area

depositional patterns of these reservoirs are established

the types of reservoir space are defined

the spatical distribution of the reservoirs are predicted

and the favorable areas for development of quality reservoirs are evaluated.A set of methods that are suitable for prediction and comprehensive evaluation of the reservoirs in Heba area is presented.
