单层铺砂条件下煤岩裂缝导流能力实验研究
Experimental study on the flow capacity of the fracturing fractures with monolayer proppant in coal beds
摘要
Abstract
The flow capacity of hydraulic fracturing fractures with low concentration proppant specifically monolayer proppant in coal beds is measured by using FCES-100 fracture flow capacity instrument, and on which the effects of proppant embedment and natural fractures are considered. The experimental results show that under lower closure pressure, monolayer proppant can support the hydraulic fracturing fractures in coal beds and good flow capacity of fracturing fractures can be obtained. There is difference in flow capacity of fracturing fractures in the coal beds of different mechanical properties. Under higher closure pressure, the flow capacity of fracturing fractures will be damaged by the proppant embedding into soft coal rock. Besides,time and natural fractures will produce influence on the flow capacity of fracturing fractures with monolayer proppant.关键词
