Abstract

Abstract:

In order to quantitatively evaluate the initial gas production contribution rate of each fracturing section of the fractured horizontal well in a strong heterogeneous gas reservoir, taking Permian He1 member gas reservoir in Xinzhao block of Dongsheng Gasfield in Ordos Basin as an example, based on reservoir geological engineering parameters, fracture characteristics, and gas production profile testing analysis, a new method for segmented production splitting of“fracture-controlled reserves”that integrated geological engineering factors was proposed. The results show that:（1）The characteristics of hydraulic fractures in Permian He1 member gas reservoir in Xinzhao block of Dongsheng Gasfield are controlled by geology and engineering. With the same construction parameters, better physical properties correspond to shorter hydraulic fractures half-length. Under the same geological conditions, larger construction displacement and greater net liquid inflow into the ground lead to longer fracture half-length, and more perforation clusters lead to shorter the fracture half-length. The ratio of half length to width of hydraulic fracture in different types of reservoirs in the same area is consistent.（2）The output of each horizontal fracturing section is significantly affected by geological engineering factors,and sections with good physical properties, good gas-bearing, and large-scale fracturing construction achieve greater post fracturing production capacity.（3）Taking into account geological engineering factors, it was clarified that the transformed “fracture-controlled reserves” have a linear relationship with the initial production capacity of each fracturing section of the horizontal well in the strong heterogeneous gas reservoir, with a correlation coefficient of 0.997, indicating that the larger fracture-controlled reserves lead to high proportion of production capacity in each fracturing section. By comparing the splitting method of “fracture-controlled reserves” with the gas production profile testing results, it was found that the relative error of splitting gas production in each section of ClassⅠand ClassⅡreservoirs is within 12.00%.

Key words: strong heterogeneous gas reservoir, hydraulic fracture, gas production profile, fracture-controlled reserves, splitting production, He1 member, Permian, Dongsheng Gasfield, Ordos Basin
