Summary In this paper, we present a new, semianalytical gravity-drainage model to predict the oil production of a cyclic-steam-stimulated horizontal well. The underlying assumption is that the cyclic steam injection creates a cylindrical steam chamber in the upper area of the well. Condensed water and heated oil in the chamber are driven by gravity and pressure drawdown toward the well. The heat loss during the soak period and during oil production is estimated under the assumption of vertical and radial conduction. The average temperature change in the chamber during the cycle is calculated using a semianalytical expression. Nonlinear, second-order ordinary differential equations are derived to describe the pressure distribution caused by the two-phase flow in the wellbore. A simple iteration scheme is proposed to solve these equations. The influx of heated oil and condensed water into the horizontal wellbore is calculated under the assumption of steady-state radial flow. The solution from the semianalytical formulation is compared against the results from a commercial thermal simulator for an example problem. It is shown that the model results are in good agreement with those obtained from reservoir simulation. Sensitivity studies for optimization of wellbore length, gravity drainage, bottomhole pressure, and steam-injection rate are conducted with the model. Results indicate that the proposed model can be used in the optimization of individual-well performance in cyclic-steam-injection heavy-oil development. The semianalytical thermal model presented in this work can offer an attractive alternative to numerical simulation for planning heavy-oil field development.

Fractured-horizontal well can effectively reduce the percolation resistance near wellbore, improve the fluid mobility and enhance the production. However, in Chang 6 ultra-low permeability reservoir, BaiBao block, HuaQing oilfield, the efficiency of fractured-horizontal well is highly poor due to the production swiftly down and water cut sharply up. For studying the unsatisfying oil development by fractured-horizontal well in HuaQing oil field, the evaluation of reservoir properties and the option of stratum for fractured-horizontal well application have been performed based on the practical geological model of BaiBao block in HuaQing oil field. The numerical simulation is used to study the effect of reservoir permeability, Thickness and Aeolotropism on the production and to optimize the horizontal length, fracture spacing, half length and conductivity. The conclusion shows that Chang 63 stratum is qualified for fractured-horizontal well application. Through the practical geological model, the optimizations of horizontal length range, fracture spacing, half length and conductivity are 800m to 1200m, 77m, 150m, and 15μm2cm, respectively. The results can be conducted for fractured-horizontal well application in HuaQing oil field.
