Based on the fluid dynamics and seepage mechanics, a mathematical analysis model in which the wellbore flow has been coupled with reservoir flow is established for the stepped horizontal well through the oil layers in three independent fault blocks. In the model, the reservoir flow is considered to be unsteady-state and wellbore pressure drop calculation model is established considering the influence of the on-way influx by using mass conservation principle and the theory of infinitesimal line congruence. Taking different curvature radius into account, a pressure drop calculation method is put forward for the layer-layer connective segments. With the mathematical analysis model, the flow behaviors of stepped horizontal well through multi-independent fault blocks has been analyzed and suggested by the calculation results, the optimal arrangement with good oil layer close to the heel side and the poor close to the finger is recommended for the minimum wellbore friction and the highest production.

Horizontal wells have become a popular alternative for the development of hydrocarbon fields around the world because of their high flow efficiency caused by a larger contact area made with the reservoir. Most of the analytical work done in the past on horizontal productivity either assumed that the well is infinitely conductive or the flow is uniform along the entire well length. The infinite conductive assumption is good only when the pressure drop in the wellbore is very small compared to the drawdown in the reservoir otherwise the pressure drop in the wellbore should be taken into account. In this paper, an improved predictive model that takes into account the effect of all possible wellbore pressure losses on productivity index of long horizontal well was developed. Results show that the discrepancies in the predictions of the previous models and experimental results were not only due to effect of friction pressure losses as opined by Cho and Shah but may also be due to all prominent pressure losses such as kinetic change and fluid accumulation experienced by the flowing fluid in a conduit. The effect is most pronounced at the early production time where initial transience at the onset of flow is experienced.

The Mathematical Model

According to the characteristics of multilateral horizontal well, by using pressure superposition and mirror image reflection theory, the mathematical model of steady percolation for multilateral horizontal well in bottom water drive gas reservoir is developed on the basis of a three-dimensional pseudo-pressure distribution model for horizontal gas wells. The wellbore model is formulated in consideration of friction loss and acceleration loss. After a case study with couple models, the effect of wellbore pressure drop on productivity of multilateral horizontal gas well is analyzed.

Multiple fractures are needed by hydraulic fracturing in order to improve the horizontal well productivity of a single well in tight gas reservoir. The calculation accuracy of productivity influences on the fracturing optimization results and the success ratio and effectiveness of fracturing treatment. This work focuses on analyzing the influence of fracture parameters on fractured horizontal well productivity in tight gas reservoir through establishing a productivity prediction model of fractured horizontal well, considering the interference between fracture and fracture and the wellbore pressure drop. Results show that the fracture parameters, such as fracture number, fracture interval, fracture conductivity and fracture length, have different influences on the productivity of fractured horizontal well and thus, the effects of fracture parameters should be taken into account when designing the fracturing treatment.
