The results of introducing technology to remove gas from the annulus of a well by creating vacuum at the Zarechnoye field

Abstract

<jats:p>The technology for pumping out and partial utilization of associated gas in oil fields by the vacuum method, using a unit for pumping gas from the annulus of the well and pumping it into the product collection system (KOGS), have been implemented at wells at the Zarechnoye field of Geotech JSC in the Republic of Tatarstan. These wells are operated by sucker rod units. The use of the KOGS unit allowed us to evaluate the effectiveness of the production system under consideration Experimental studies have shown that a decrease in annular pressure causes a significant increase in the dynamic level and an improvement in the conditions of oil inflow to the well. The operation of sucker rod units in such conditions provides an increase in the delivery and filling coefficients of the pump and, accordingly, an increase in oil production.</jats:p>
