In the published article, there was an error in the article title. Instead of “Diagenesis of the first member of Canglangpu Formation of the Cambrian Terreneuvian in northern part of the central Sichuan Basin and its influence on porosity”, it should be “Diagenesis of the first member of Canglangpu Formation of the Cambrian Series 2 in northern part of the central Sichuan Basin and its influence on porosity”.

In the published article, there was an error in Figure 1 as published. In the picture, the age of the strata is incorrect. The corrected Figure 1 and its caption appear below.

Location and comprehensive stratigraphic histogram of the study area. (A) Structural unit division of the Sichuan Basin (modified from Reference Hu (2021)); (B) Lithologic histogram of the Canglangpu Formation in Well CT1. GR: natural gamma ray; Rt: true formation resistivity; Rxo: flushed zone formation resistivity.

In the published article, there was an error in Table 2 as published. The stratigraphic age in the table name is incorrect. The corrected Table 2 and its caption appear below.

In the published article, there was an error in Figure 7 as published. In the picture, the age of the strata is incorrect. The corrected Figure 7 and its caption appear below.

In the published article, there was an error. The stratigraphic age is incorrectly divided. A correction has been made to the Abstract, paragraph 1. The corrected sentence appears below:

“In this paper, taking the first Member of the Canglangpu Formation of the Cambrian Series 2 in the northern central Sichuan Basin as an example.”

A correction has been made to the keywords. The corrected keywords appear below:

“diagenesis, Series 2, Cambrian, the first member of Canglangpu Formation, northern part of the Central Sichuan Basin”

A correction has been made to the Introduction, paragraph 1. The corrected sentence appears below:

“The Central Sichuan Paleo-uplift controls the process of hydrocarbon accumulation in the Sinian-Cambrian Series 2 in the Sichuan Basin. At present, the exploration horizons in this area are mainly concentrated in the Sinian Dengying Formation and the Cambrian Series 2 Longwangmiao Formation, and there are few studies on other horizons.”

A correction has been made to the Conclusion, paragraph 1. The corrected sentence appears below:

“In this paper, taking the Cang 1 Member of the Canglangpu Formation of the Cambrian Series 2 in the north part of the central Sichuan Basin as an example.”

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
