致密油属非常规油气资源范畴,具有储层物性差、资源丰度低等特点,目前致密油气研究主要采用“七性关系”评价方法,岩性和总有机碳含量(TOC)是致密油“七性”评价中重要的组成部分。由于组成致密储层由矿物、干酪根、孔隙度和束缚水等多种组分构成,常规测井方法进行定量评价致密储层的组分特征及总有机碳含量(TOC)存在很大难度。Geolog软件为定量评价致密储层的矿物组成和总有机碳(TOC)含量提供了有效手段。本文以辽河坳陷大民屯凹陷致密油为例,应用Geolog软件的Multimin模块和Unconventional模块对致密储层岩性及总有机碳(TOC)含量进行定量评价,与常规测井评价方法对比,该软件在致密油领域的应用具有较好的效果。
The tight oil belongs to the category of unconventional oil and gas resources. It has the characteristics of poor reservoir properties and low resource abundance. At present, the research on tight oil and gas mainly adopts the method of “seven-relationship”, lithology and TOC Oil “seven sex ” evaluation of the important part. Due to the composition of tight reservoirs composed of minerals, kerogen, porosity and irreducible water, it is very difficult for conventional logging methods to quantitatively evaluate the component characteristics and total organic carbon (TOC) in tight reservoirs. Geolog software provides an effective tool for quantitative assessment of mineral composition and total organic carbon (TOC) in tight reservoirs. Taking the tight oil in Damintun depression of Liaohe depression as an example, the Geolog software Multimin module and Unconventional module were used to quantitatively evaluate the lithology and total organic carbon (TOC) in tight reservoirs. Compared with the conventional logging evaluation methods, The application of software in the field of tight oil has a good effect.
