煤层气井压裂液的研究郑秀华地矿部探矿工程研究所与常规油气井开发一样，水力压裂工艺是目前应用最广泛的煤层气增产措施，尤其是低压低渗地层，压裂技术经常起关键作用。但是二者存在许多不同之处，主要在于：①煤层与常规储层的机械性质不同。与常规储层相比，煤层杨氏...
Research on Fracturing Fluid in CBM Well Zheng Xiuhua Institute of Prospecting and Mines, Ministry of Geology and Mineral Resources As with the development of conventional oil and gas wells, hydraulic fracturing is the most widely used CBM stimulation measures, especially in low pressure and low permeability formations. Fracturing technology often plays a key role effect. However, there are many differences between the two, mainly because: ① the mechanical properties of coal seams and conventional reservoirs are different. Compared with the conventional reservoir, the coal seam Yang ...
