Abstract: Aiming at the issues that low porosity and low permeability reservoir deliverability prediction model is impacted a lot by sensitivity factors,there is an unapparent difference between the main and secondary factors when deliverability is low,and deliverability prediction and evaluation are relatively difficult,the Xia wells 77 and 79 in Xiazhijie area,Junggar Basin are taken as examples to carry out pilot test for low porosity and low permeability reservoir deliverability prediction,different deliverability prediction models and the applicable conditions are summarized,further,the optimized Darcy model,Jones.et al model,Vogel/Harrison (1968) model and fracture model are selected to predict and test low porosity and low permeability reservoir deliverability.By analyzing the compatibility of predicted and tested deliverability,it is verified that predicted result based on well logging data matches well with test result,reliability of the prediction deliverability model can be confirmed.

Key words: well logging, deliverability prediction, low porosity and low permeability, reservoir, prediction model
