山东省页岩气有利勘探层系与资源评价
|
摘要
页岩气是一种新型的高效、清洁能源,具有自生自储的特点,主要以游离气、吸附气和溶解气等多种形式赋存于富有机质泥页岩中。利用地球化学、测井、录井等资料系统地分析山东省页岩气的形成条件,认为干酪根类型为Ⅱ—Ⅲ型的上古生界山西组—太原组海陆交互相泥页岩、Ⅱ—Ⅲ型的新生界孔二段湖相泥页岩和Ⅰ—Ⅱ型的新生界沙四段—沙三段湖相泥页岩是山东省页岩气的有利勘探层系。以钻探参数井的现场解析气数据为基础,建立以总有机碳含量计算干酪根类型为Ⅱ—Ⅲ型的湖相和海陆交互相泥页岩、以气油比计算干酪根类型为Ⅰ—Ⅱ型湖相泥页岩的适用于山东省的含气量计算模型。基于已确定的页岩气资源评价的关键参数,估算山东省页岩气有利区的资源量为1.42×10~(12)m~3。
Shale gas is a new type of efficient and clean energy. It has the feature of"self-generation and self-accumula-tion",and it is hosted in organic-rich shale in various forms such as free gas,absorbed gas and solution gas. According togeochemical,well logging,mud logging and other data,the shale gas forming conditions in Shandong Province are systemati-cally analyzed. It is believed that the marine-continental transitional shale with type Ⅱ-Ⅲ kerogen in Upper PaleozoicShanxi-Taiyuan Formation,the lacustrine shale with typeⅡ-Ⅲ kerogen in the 2 nd member of Kongdian Formation in Ce-nozoic,and the lacustrine shale with typeⅠ-Ⅱkerogen type in the 3 rd member and the 4 th member of Shahejie Formationin Cenozoic are favorable exploration strata of shale gas resources in Shandong Province. Based on the on-site desorptiongas data extracted from the parameter wells,shale gas content calculation models suitable for Shandong Province are pro-posed,the total organic carbon is used to estimate the gas content of lacustrine facies and marine-continental transitional fa-cies shale with typeⅡ-Ⅲ kerogen,and the gas/oil ratio is used to estimate the gas content of lacustrine shale with typeⅠ-Ⅱkerogen. According to the identified key parameters of shale gas resource evaluation,the resources of favorable shale gasarea in Shandong Province is estimated to be 1.42×10~(12) m~3.
