为了弄清研究区储层的分布情况,准确地评价气田的潜在能力,减小勘探风险,需要建立比较精细的储层模型,然而该地区当前仅有5口钻井,难以获取有关砂体形态、宽厚比、接触关系等方面的信息。因此在研究区附近选择了相同目的层的20条露头剖面进行详细描述、测量和研究,获取了所需的相关信息,建立了相应的地质知识库,并在此基础上,结合钻井和岩心资料,采用随机模拟技术建立了比较合理的储层模型,为该气田储量的准确评价提供了可靠的地质依据。

A big gas field was found in xinjiang.In order to evaluate exactly the reserves of this gas field and decrease exploration risk and investment,we need to build a reservoir model which can describe reservoir distribution.But there are only five wells and the well distance is more than several kilometers,it is difficult to get the informations about sandbody geometrical form,the ratio between width and thickness,the contact types between different sandbody and so on.It is necessary for us to erect a geologica.
