摘要：

为了揭示物质组分对火成岩风化壳储层发育程度的影响,在全岩分析基础上,以碱度为分类依据选取了32块不同碱度的新鲜火成岩样品,通过室内溶蚀实验模拟岩石在风化淋滤作用下的增孔特征,比较样品溶蚀前后的孔隙分布特征以及孔隙度、渗透率值大小,结合井下不同碱度天然溶蚀火成岩样品的储层特征,对不同碱度火成岩发育风化壳储层的差异性进行了对比和分析。溶蚀实验中化学成分上判别为过碱性的火成岩绝对增孔平均约5%以上,碱性岩绝对增孔约4.6%,而钙碱性火成岩绝对增孔只有2.1%,表明碱度特征是火成岩次生储集空间发育的重要控制因素。通过岩石主量元素与增孔值回归分析,明确K、Na、Ca、Mg等元素含量与火成岩溶蚀增孔能力具有较好的相关性。碱度较高的火成岩中因为含有相对较多的活性组分,在相似的酸介质环境下,其比钙碱性火成岩溶蚀增孔的能力更强。

Abstract:

In order to get a clear understanding about the influence of volcanic rock composition on erosion in creating porosity during deuteric processes, 32 fresh igneous rock samples are picked out and sorted according to their whole rock alkaline. An indoor eroding experiment is employed to simulate the rocks' pore changing processes. Pore distributions are observed on cast thin sections before and after erosion and their porosity and permeability are also detected. Combining with the reservoir characteristics of igneous samples from drilling wells under natural erosion, the difference of different alkali content igneous rocks are compared and studied. The experiment show the strong alkaline igneous rocks have an absolute pore growth by more than 5%in average after erosion, and the values are 4.6%and 2.1%for alkaline and calc-alkaline igneous rocks respectively. The result indicates that the contents of alkali in igneous rocks act as one of the important internal factors in forming high-quality weathering crust reservoirs. By regression analysis of major elements and rock pore increasing value, it is revealed that the contents such as K, Na, Ca, Mg have good correlations with the pore increasing ability under erosion condition. Because of relatively more active components, the alkali-rich igneous rocks have a stronger ability to develop better reservoir than the calc-alkaline ones under the same acid erosion environment.

Key words: igneous rock, alkaline, erosion experiment, secondary porosity, difference
