摘要
延川南区块地质储量丰富,具有较大的发展潜力。根据延川南区块储层特征,通过室内实验和数值模拟方法开展了压裂参数（裂缝参数、施工材料、施工规模、施工管柱）的优化研究,形成了适合延川南区块煤层气压裂配套的工艺技术系列。现场应用表明,延川南区块煤层气井压裂后,经过1~2年的排采,增产效果显著,有效地提升了延川南区块整体开发水平。
South Yanchuan block has rich geological reserves with great development potential. According to the characteristics, in- door tests and numerical simulation methods, optimization of fracturing parameters such as fracture parameters, construction materi- als, construction scale and construction strings is carried out, and the suitable fracturing technology series of CBM in South Yanch- uan block are formed up. Field application shows that during 1-2 years＇ drainage after fracturing, production increasing effect is obvious, therefore, the overall development level of South Yanchuan block is promoted effectively.
