Maliuchang Of The Jialing River Formation Reservoirs Logging Evaluation Methods

In the course of the exploration of Jialingjiang Group Reservoirs in Maliuchang Structure of South Sichuan, a lot of industrial gas sources are acquired, the well potentiality of oil and gas resources are expressed. With the development of exploration at Jialingjiang Group Reservoirs in this area, the number of resulting problems is appeared increasedly, such as the difficulties of reservoirs distinguishing, the identification of reservoirs fluid properties, especially the difficulties of fractured reservoirs interpretation, and the system research of logging analysis have not been developed so that the deviation of some well interpretations were appeared. With the help of logging data, the logging response features of Jialingjiang Group Reservoirs should be researched and analyzed from the technology of log interpretation, it is necessary that a series of the technology of log reservoirs distinguishing, the calculational methods of reservoir parameters and the identification of reservoirs fluid properties must be established. Therefore, the research of Jialingjiang Group can further distinguish the feature of reservoirs, improve the coincident ratio and precision of log interpretation, and be used to guide the exploration of oil and gas at Jialingjiang Group Reservoirs in this area or others.The objective of this program research is to establish the interpretation & evaluation methods of Jialingjiang Group Reservoirs in Maliuchang Structure. It is important that the result is used to guide the log interpretation, improve the coincident ratio of interpretation and find oil and gas reservoirs in time, and develop the reevaluation of oil and gas resources in future.The researcher have made some progress on the formations of this area from the elementary research of log evaluation; the data are completed because some wells digital and imaged logging were taken by the system of MAXIS-500 and 5700; the geological research of sedimentary facies and reservoirs provide the condition of material and technology for the realization of this program.The research is mainly on the following:1. Collect and coordinate the materials of the well logging, testing and completion report of the geological summarization.2. Observe the field geological profile and core.3. Experiment on the electricity of rock and intrusive mercury.4. Process, analyze and integrated interpret well logging data.In short, through the research above, the interpretation model of reservoir parameters is established; the identification of Jialingjiang Group reservoirs fluid properties adapted to this area is achieved; the testing suggestion at T|j4 , reservoir of Well 13 was submitted and acquired success, and the future up-testing suggestions at T₁j₃⁴ and T₁^j₁⁴ , reservoirs of Well 6, 8. 10 are submitted; According to the features of Jialingjiang Group Reservoirs in Maliuchang Structure, the optimization suggestions on the series of logging are provided.
