Aiming at the challenges of poor capping rock, and in view of the development of lower aqueous layer and natural fractures of Fan134-1 well, the research and application of secondary sand fracturing technology are conducted to the well. According to reservoir geological features and well conditions, and based on the technical difficulties of fracturing operation on Fan134-1, the research is conducted with respect to proppant quantity, optimization of proppant ratio to the second operation, pump-stopped time, selection and evaluation of fracturing fluids and proppant, and supporting technical measures. The secondary sand fracturing operation is thereafter carried out on November 26, 2012. The operation lasted 189 minutes with accumulatively loading of 468 m3 fracturing fluids and 46 m3 proppant. The pump stopping time was 115 minutes. Three days after operation, the average fluid flowing production is achieved at 27.1 t/d, and average daily oil production at 13.2 t, the stimulation effect and the economic benefit are remarkable.
