The Research of Ultra-low Permeable Reservoir Horizontal Well Pattern Optimization
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 3
Abstract
Horizontal well fracturing technology is a low permeable oilfield development mining technology. Reservoir physical properties changes after fracturing. In this paper, on the basis of a large number of indoor experiments, we analyze the threshold pressure gradient, pressure sensitive effect after fracturing. In view of the actual block, in the process of numerical simulation, considering the above change rule, and adopts the method of orthogonal experiment, optimization was studied for the low permeability reservoir horizontal well pattern. Keywords: Ultra-low Permeable ; Threshold Pressure Gradient; Stress Sensitivity; Orthogonal Test
