Antlers Field - Li Ziba Jialing River Group Reservoir Logging Interpretation Methods

As the further exploration and development of the gas and oil fields, and along with the oil and gas resources scarcity gradually, using logging data to review the old oil and gas fields appears particularly important for those fields which has long development history to increase their oil and gas reserves. In view of the less application of new logging technology and the well logging quality is not high, this article is the interpretation for old well that based on the need of "Fine Interpretation Of Reservoir Of JiaLing River Group In Southern Sichuan Area". The purpose of this article is based on the previous studies, through to comprehensive analysis of the geologic, drilling, logging, well logging, core experiment and dynamic data of production to establish a set of suitable evaluation model of the carbonate reservoir logging for the study area by conventional well logging data. The result could provide guidance for the follow-up exploration and production. Firstly, this article given a detail study about the characteristics of reservoir lithology, reservoir space, and reservoir types of carbonate reservoir in southern Sichuan area of Jialing River group on the based of the analysis and study of the characteristics of carbonate reservoir in the study area. According to the type of reservoir space is different, the area of the reservoir is divided into three types, namely, the pore type reservoir, fractured reservoir and fractured porous reservoir, also, analyzes and summarizes the Performance of fracture in conventional well logging curve by a combined method that use geological, conventional logging data logging and core analysis data. Establishes a set of method to evaluation the validity of fractured-vuggy carbonate reservoir in southern Sichuan area of JiaLingjiang formation. Secondly Analysis the applicability of various fluid identification methods in the research area through geological data, well logging data, test data, process analysis, and dynamic production data which is based on the Reservoir types and reservoir space characteristics. Established reservoir interpretation model and parameter calculation model and a new saturation interpretation model based on the triple porosity model--matrix pore, fracture porosity, non-contact pore for the study area. Finally, Carry out research on logging comprehensive interpretation based on the model that has been established and the dynamic production data...
