Justification of the exploitation of one of the gas fields in the north of Western Siberia by wells with an increased diameter of the site in the productive formation interval
Relevance. The need to search for technical solutions aimed at increasing the flow rates of gas wells, as well as searching for reserves to increase the resource of gas field equipment. Aim. To estimate the multiplicity of increase in the flow rate of a gas well, the possibilities of reducing the depression on the formation under the condition of maintaining the previous flow rate, as well as to assess the degree of reduction of the pressure gradient on the well walls with an increase in its diameter in the interval of the productive formation. Methods. General empirical methods, mathematical and statistical methods. Results. Taking into account the component composition of gas from one of the fields in Western Siberia, the authors calculated the expected flow rates of gas wells of various diameters, estimated the possibilities of reducing the pressure gradients on the well walls and depressions, which is important from the point of view of preventing premature water cut and preventing sand removal from gas wells. Based on the calculated data, the authors made a conclusion about the advisability of increasing the diameter of gas wells with the highest expected flow rates. It is high-flow wells that are characterized by the highest pressure gradient reduction factor and the greatest potential for depression reduction. The work established that for the field under consideration, when the diameter of a high-flow well (flow rate from 1 million m3/day) is increased from 114 to 168 mm, the reduction in pressure gradient is 4.6 times, for wells with flow rates from 50 to 100 thousand m3/day it is 2.5–2.9 times. Also, for high-flow wells, the expected flow rates grow more significantly with an increase in their diameter, which in its turn creates greater opportunities for reducing depression on the formation.
