Abstract

Fractured horizontal wells are widely applied in the development of tight reservoirs nowadays, which will stimulate the seepage zone, reduce resistance near the wellbore and increase productivity. Through analyzing all factors affecting fracturing development effectiveness, select the key factors, and then introduces a series of dimensionless variables to describe reservoir characteristics. All influencing factors with varying values are calculated through a Box-Behnken design. The results are interpreted by a response surface method, and then a quick screening model is obtained to evaluate fractured horizontal wells in tight reservoirs. Sensitivity analysis of single factor and its interaction is carried out based on this model. The research manifests that directing to fractured horizontal wells development in tight reservoirs, this evaluation model and numerical simulation have less error, so it is acceptable to predict the tight reservoirs development and select the optimal development program with this model.
