Peculiarities of change in the main formation parameters of the KS and PK suite deposits at the Pirallakhi adasy field

In order to analyze the changes in the parameters of the main reservoir parameters by area and depth at the Pirallahi adasy field, the results of the interpretation of core and logging data were used. For this, the data from well logging and the results of core analysis over the area were collected and analyzed. The results of interpretation of the data of complex well logging studies of wells carried out at the field and the results of analysis of core materials are systematized, statistical analysis is carried out. In the section of each well, reservoirs were identified, characterized by reservoir properties for the KS and PK formations, their porosity, clay content, oil and gas saturation, and permeability were determined. The weighted average values of these parameters for individual wells were calculated and distribution graphs were drawn up. Dependences are established between the parameters of the filtration-capacitive characteristics and correlations are built. The graphs of dependence are built between the parameters characterizing the reservoir characteristics, porosity and clay content, permeability and porosity in the KS and PK formations. As a result of the studies carried out, it can be noted that the Pirallahi adasi field, despite the fact that it has been in operation for a long time, the obtained results of the well logging data interpretation for the KS and PK formations, the identified reservoirs have high properties that the hydrocarbon reserves of the field have not been exhausted. Taking into account the above, it is more expedient to continue drilling and development of new wells in the best possible way, choosing the optimal well network at the Pirallahi adasy field.
