【摘要】：为了得到煤储层特征与测井资料间的关系,从区域地质背景出发,通过对煤心特征、测井、录井及地震等资料分析,研究了沁水盆地樊庄-郑庄区块煤层结构及高阶煤储层的岩性、物性、含气性、含水性、产气性等"五性"特征。结果表明:平面上,樊庄-郑庄区块煤层结构的演化横向上具有较强的规律性,即樊庄地区南部夹矸个数最少,一般为1~2个,其次是郑庄地区,一般2~4个,樊庄北中部夹矸数量最多,一般为3~6个;樊庄灰分整体较低,平均为11%;而郑庄地区的灰分相对较高,平均为18%;樊庄地区平均孔隙度为9%,郑庄地区平均孔隙度为5%;煤质参数越大,单井产能就越高,其中樊庄西南部、中部区域煤质参数最好;郑庄地区的煤质参数整体比樊庄地区差,与实际生产相对应。
[Abstract]:In order to obtain the relationship between coal reservoir characteristics and logging data, based on the regional geological background, the coal core characteristics, logging, logging and seismic data are analyzed. The coal seam structure and high-order coal reservoirs in Fan-zhuang-Zhengzhuang block, Qinshui Basin, are studied in this paper, such as lithology, physical properties, gas-bearing properties, water-bearing properties, gas-producing properties, and so on. The results show that: on the plane, The evolution of coal seam structure in Fanzhuang-Zhengzhuang block has strong regularity, that is, the southern part of Fanzhuang area has the least number of gangue, which is generally 1 ~ 2, followed by Zhengzhuang area (2 ~ 4), and the central part of Fanzhuang has the most quantity of gangue, which is generally 3 ~ 6. The overall ash content in Fanchang is relatively low, with an average of 11. In the Zhengzhuang area, the ash content is relatively high, with an average of 18. The average porosity in the Fanchang area is 9, and the average porosity in the Zhengzhuang area is 5. The larger the coal quality parameters, the higher the productivity of a single well, among which the southwest of Fangzhuang, The coal quality parameter in the central region is the best, and the coal quality parameter in Zhengzhuang area is worse than that in the Fanzhuang area as a whole, which corresponds to the actual production.
