Use advice for data set Users of this data should consider the differences in formation pressure systems between various structural zones when applying wellbore structural designs outlined by the data set. The data is derived from detailed rock mechanics experiments, logging, and formation pressure tests, and should be used to tailor drilling parameters and casing programs for specific geological conditions in the Weining block. Utilization should involve a validation process against additional test data to ensure the reliability of the models and their applicability in actual drilling operations. Special attention should be given to the design for ensuring drilling success rates and the avoidance of slim hole drilling completion issues.
Technical purpose of product or process The data set represents geological and engineering methodologies used primarily in the exploration and drilling of oil and gas wells within varied structural belts of the Weining block. This includes optimization of wellbore structural design using a top-down approach influenced by rock mechanics, logging, and formation pressure tests specific to the South Ayashi and Winnie structural belts, enabling efficient and accurate drilling to achieve the desired depth and geological targets.

General comment on data set According to the difference of pressure system in different structural belts of Weining block, the fine study of three pressure profiles is carried out by synthesizing a number of data. On this basis, the wellbore structure of South Ayashi and Winnie structural belts is optimized by using the top-down wellbore structure design method, aiming at providing technical support for excellent and fast drilling in this exploration area.

Data selection and combination principles Based on logging data, three pressure profiles of South Ayashi structural belt and Winnie structural belt in Weining block are established. After repeated checking and verification by test data, MDT data and formation integrity test data, three fine pressure profiles are finally formed in Weining block
Deviation from data selection and combination principles / explanations None
Data treatment and extrapolations principles The geological understanding of exploration blocks is generally shallow, and the drilling success rate should be paid attention to in wellbore structure design. Therefore, the top-down design method combined with casing strength check is selected to make the upper large-size casing run as deep as possible, so as to ensure the drilling reach the target horizon and avoid the completion of slim hole drilling
