Abstract
The set of equipment for gas extraction from wells (KOGS) has been developed to increase a pump’s feed rate and the equipment’s production rate, and to reduce wear of PCPs. Reducing gas pressure in the annulus is a significant
reserve for increasing the oil production. The gas content in oil, production rate and water cut in the wells equipped with KOGS have been measured. Studies have determined that application of the system under the maximum gas pressure in the annulus of the well can provide the highest efficiency. The effect of a pressure change in the annulus on the dynamic level of formation fluid in the well was studied. The necessity of gas removal from the annular
space and bottomhole zone of a well was substantiated. The implementation of evacuation of annular gas made it possible to reduce the wear of screw pumps: the wear degree equaled 24%, reducing by 33%.
Materials and methods
The MIKON-101 set of instruments was used to determine the liquid level and measure the pressure in the annular space of oil wells, as well as to study (by dynamometer measurements) the operation of wells with deep rod pumps in order to control the operation of pumping equipment and obtain a dynamogram (load curves) of the pumps. Data interpretation was performed by the Measurement Manager software with the subsequent output of information to the
Kron Information System.
