Leakage of casing column is a cause offast water increase in products of oil-wells. The article discussed layout plan of “ESCP with packer”, in particular a gas withdrawal through capillary pipeline. It is described the designs packer with Inkomp-neft capillary pipeline. Experience of arranges applications is given. An approach to hydrates deposition in the capillary pipeline assessment is covered.
Materials and methods
Runge-Kutta method. Method for thenumerical solution of steady-state heat equation the Stefan problem.
The article considered a possibility of hydrates deposition in the small bore pipeline. Hydrates increase rate and depth of possible deposition are determined.
It was designed a mathematical model to forecast the possibility of commencement and rate of growth of the hydrate layer formation and depending on the bottomhole pressure,temperature gradient of bore hole and gas composition. That, in its turn, allows making a prognosis of the time of uninterrupted performance of the gas withdrawal system. In case of necessity to set the periodicity of the armored polymer pipeline purging to destruct and remove the hydrate layer to save the flow capacity.
