Determining acid injection treatment parameters

摘要

The present disclosure relates to determining acid injection treatment parameters. One example method includes identifying one or more characteristics of a rock structure; and determining one or more parameters of an acid injection treatment to produce a specified flow structure in the rock structure when the acid injection treatment is applied, the one or more parameters of the acid injection treatment determined based on the one or more characteristics of the rock structure and including at least one of an injection flow velocity or a characteristic of an acid to be used in the acid injection treatment.

1. A method comprising:
receiving a plurality of rock structure characteristics, the rock structure comprising a rock formation that includes a wellbore formed therethrough; receiving a plurality of core sample characteristics, the core sample associated with the rock structure; determining, by one or more processors of a computing system, based on the rock structure characteristics, an injection flow velocity of an acid injection treatment to produce a specified flow structure in the formation when the acid injection treatment is applied; determining, by the one or more processors, based on the injection flow velocity, the rock structure characteristics, and the core sample characteristics, a lab core flow rate of the acid injection treatment; and determining, by the one or more processors, based on the lab core flow rate and the rock structure characteristics, a field well flow rate of the acid injection treatment.
