The Efficiency Calculation and Structural Optimization of Eddy Composite Drainage and Gas Recovery

Abstract:

Part of the gas fields utilize eddy current instruments to drainage and gas recovery currently, while the mechanism of drainage and gas recovery is not clear. This article conducts drainage and gas recovery simulating caculation, analyses the impact of gas flow rate, the moisture content of bottomhole and eddy current tool structure of its drainage effect, basing on the theory of gas-liquid two-phase flow. The results show that: the gas flow rate, moisture content and the normal section shape of eddy current tool spiral piece are the main factors that affect the eddy current tools draining. As follows: the larger the gas flowing rate, the better the tool draining effect; when the bottomhole moisture content is less than 10%, the draining effect is not obvious; but when the bottomhole moisture content is greater than 10%, with higher the moisture content, the draining effect is more obvious; the normal section shape of spiral piece is better to be rectangular rather than trapezoidal; the direction of rotation of the spiral piece (left and right hand) has little effect on draining.
