摘要:
分析黔西发耳矿区的开发地质条件,基于煤储层可采性对多煤层开发层段进行优选,建立可动资源指数评价指标,并依据该指标开展了多煤层合采开发层段优选研究。结果表明:合层开发的煤层等温吸附曲线离散度越小、可动资源指数越高越适宜进行合层开发。研究区FE-S1井优选7#,13-1#,15-2#三个煤层进行分层压裂、合层排采,开发效果好,可采性最高。根据可动资源指数对研究区的一口开发井开展合采开发层段优选,优选后该井平均日产气超过2 000 m3,产气效果好。验证了可动资源指数可作为多煤层合层开发层段合理性的评价指标,该研究为多煤层合采开发提供了理论参考。
Abstract:
Analyzing the development geological conditions of western Guizhou Fa′er mining area, the optimum selection of multi-seam development intervals was carried out on the basis of the recoverable coal reservoirs, and the evaluation of movable resource index was established. The results show that: the smaller the dispersion of the isothermal adsorption curve of coal seams developed in combination, the higher the movable resource index, the more suitable for layer development; Well FE-S1 in the research area was optimized to conduct stratified fracturing and combined seam drainage for three coal seams(7#, 13-1# and 15-2#), with good development effect and highest mining feasibility; according to the movable resource index, it is preferred to carry out the combined mining development section of a development well in the study area. After that, the average daily gas production of the well is more than 2,000 m3/d, and the gas production effect is good; it is verified that the movable resource index can be used as an evaluation index for the rationality of the multi-coal layer development interval. This study provides a theoretical reference for the development of multi-coal mining.
