致密砂岩支撑裂缝气测导流能力研究

Abstract

Abstract:

After the guidance of the results of gas flow conductivity test for the optimization of fracturing design of tight gas reservoirs, the prediction of post fracturing effect and the optimization evaluation of proppant were more pertinent and reasonable. The current common gas flow conductivity tests mainly focused on the influence of the closure pressure, proppant particle size and proppant type on the flow conductivity. Based on the analysis, we designed the experimental scheme about the influence of fracturing fluid type and laying mode on gas flow conductivity by using the DL—2000 fracture support conductivity tester and according to the SY/T6302—1997 "proppant filling layer short-term conductivity evaluation and recommendation method". The results showed that the fracture conductivity decreases when the closure pressure increased; the larger the proppant diameter was, the greater the conductivity would be; while the greater the closure pressure was, the greater the decreasing amplitude of the flow conductivity would be. The laying mode for the rear gas logging fracture conductivity was the best. The fracturing fluid damage made the cracks in the gas logging diversion capacity decreased by 80 %~95 %.

Key words: supporting fractures, gas flow conductivity, permeability, fracturing fluid damage, paving methods
