Abstract
Numerous studies have established and long-term experience in the exploration and development of hydrocarbon deposits has confirmed that the filtration and capacity properties (FCP) of reservoir rocks vary both in terms of the thickness of the reservoir and the extent of the deposit. Moreover, while the patterns of FCP variation for terrigenous reservoirs have been studied in detail, the properties and parameters of carbonate reservoirs vary randomly and unpredictably from well to well, making it impossible to make reliable predictions.
The results of a study of the effect of depression on well productivity are presented. It is proved that it is necessary to take into account the petrophysical properties and parameters of low-permeability rocks in the bottom zone of the formation, gas and water saturation, the direction of filtration flows, changes in the stress state in the structure of the hydrocarbon deposit for effective geological exploration and well development.
Key words:
development of hydrocarbon fields, increasing the efficiency of geological exploration, well development, well productivity, filtration and capacitance properties of reservoir rocks, bottom-hole formation zone, well flow rate
