Abstract

In order to accurately evaluate the Previous HitgasNext Hit production property of Previous HitshaleNext Hit Previous HitgasNext Hit reservoirs, the key parameters affecting the Previous HitgasNext Hit production in Previous HitshaleNext Hit Previous HitgasNext Hit reservoir were selected based on the analysis of the Previous HitgasNext Hit production test data of the Fuling Previous HitShaleNext Hit Previous HitGasNext Hit Field, and further divided into both the Previous HitshaleNext Hit Previous HitgasNext Hit production factor GPF and the reservoir evaluation index LEI. They formed the basis by which the GPF-LEI Previous HitgasNext Hit production property evaluation method for Previous HitshaleNext Hit Previous HitgasNext Hit reservoir was established by taking the evaluation parameter scoring standard as the constraint condition. The site verification in the Fuling Previous HitShaleNext Hit Previous HitGasNext Hit Field showed that the better the kind of Previous HitgasNext Hit production evaluation category, the higher the open flow capacity. The open flow capacity of Previous HitshaleNext Hit Previous HitgasNext Hit reservoir predicted by this method basically matches with actual test results, and the relative error is 15. 5%. Research results indicated that the Previous HitgasNext Hit production category of Previous HitshaleNext Hit Previous HitgasNext Hit reservoir evaluated by this method had a good correlation with open flow capacity, and provided a new method for evaluating the Previous HitgasNext Hit production property in Previous HitshaleNext Hit Previous HitgasTop reservoirs.
