Experiments on the conductivity of propped fracture in tight dolomite reservoirs were conducted to analyze the effects of different factors on the conductivity of propped fractures and thus explore the adaptability of proppant fracturing technology to dolomite reservoir stimulation. The experimental results showed that the factors affecting the conductivity of propped fractures in dolomite reservoirs are as follows：the particle sizes of proppants，proppant concentrations，proppant injection modes，proppant laying methods，and proppant strength. Compared with a single proppant，the mixed proppant can obtain better conductivity，and a larger particle size is accompanied by a higher proportion of proppants and better conductivity. In addition，the conductivity of fractures registers significant fluctuations under the pulsed proppant injection mode，but it can satisfy the stimulation requirement of dolomite reservoirs. Considering the fracturing effect and cost，the on-site sand fracturing needs in the dolomite reservoir can be met with the proppant strength of 69 MPa and an average proppant concentration of 1.8 kg/m2. The dolomite reservoir has a small fracture width because of the large Young’s modulus and high closure stress. Hence，the risk of proppant plugs in proppant fracturing can be reduced to a certain extent by the pulsed proppant injection mode.
