A correction method for a microseism interpretation fracturing fracture parameter result. The method includes classifying the communication modes of a block sampling fractured wells to be corrected according to the matching degree of micro seismic monitoring result and sand adding amount; correcting the volume coefficient of each said classified fractured well single well, and the volume correction coefficient Bv of each said fractured well is: wherein, [LH]is a calculation value of a micro seismic monitoring interpretation result; [LH]is a theoretical calculation value obtained by using field construction parameters; C, calculating the classification volume correction coefficient of each class of fractured wells according to the calculated single well volume correction coefficient of each said fractured well. The micro seismic interpretation result can be corrected in combination with the field construction parameters, so that the micro seismic monitoring data can be utilized to truly interpret the effective fracture morphology after fracturing.

A method for producing stable fertilizer by nano-carbon sol comprising: the pH of the nanometer carbon sol is &#x3c;2.2, conductivity is 2800-3400 &#x3bc;s/cm; the content of carbon content of nano-carbon sol reaches 0.57-2%, particle size&#x3c;100 nm, potential difference is &#x2212;30-35 mv; The addition of nano carbon sol as synergist in nitrogen-containing fertilizers was 1.05 to 10% of the weight of nitrogen-containing fertilizers. Nano-carbon sol is added in the growing process of crops, or in the production process of nitrogen-containing fertilizers. The invention can make fertilizer nutrient supply stable and increase yield obviously: there was no lack of fertilizer in the late stage of crop, and the average yield increased by 5-18%; the utilization rate of fertilizer can be improved. The nitrification inhibition rate of the present invention reaches 6.3-6.8%, the inhibition rate of nitrification of nitrogenous compound fertilizer was 19-25%, it is an environmental friendly fertilizer synergist, and it will not cause any residual damage to soil crops.
