摘要

针对低勘探程度致密砂岩气区的特点，优选资源丰度地质类比法和基于储层体积的随机模拟法进行致密砂岩气资源评价，并根据国内外多个典型致密砂岩气藏的地质条件对比建立了致密砂岩气地质评价和资源丰度类比标准。以库车盆地东部侏罗系致密砂岩气为例，首先采用多要素叠加预测了致密砂岩气有利分布区块，对不同区块分别进行地质评价和参数研究，然后分别利用资源丰度类比法和随机模拟法对各个区块进行资源量的计算。计算表明库车东部侏罗系致密砂岩气资源量约为1.4×10¹²m，具有较大的勘探开发潜力。

Abstract

According to the characteristics of tight sandstone gas plays of low exploration degree,two methods such as geological analogy in resource abundance and stochastic modeling based on reservoir volume were chosen to assess tight sandstone gas resources.Based on the geological analogy of some typical tight sandstone gas reservoirs,criteria of geological evaluation and resource abundance analog were established.The Jurassic tight sandstone gas in East Kuqa Basin has been taken as an example.Firstly,using the multi-factor congregating method,favorable zones of tight sandstone gas were predicted,and geological evaluation and parameters were studied for each zone.Then,using resource abundance analogy method and stochastic simulation method,gas resources of each tight sandstone gas zone were calculated.The results show that Jurassic tight sandstone gas resource in East Kuqa Basin is about 1.4 trillion square,which has great exploration and development potential.

Key words： Tight sandstone gas; Geological analogy; Resource evaluation; Stochastic simulation; Kuqa Basin
