Production Profile of Horizontal Wells in Strongly Heterogeneous Tight Gas Reservoirs in Sulige Gas Field

doi:10.7657/XJPG20220312

Abstract

Abstract:

In order to determine the productivity of each fracturing section of a horizontal well after staged fracturing in the Sulige gas field, the production profile of horizontal wells and its influencing factors such as reservoir heterogeneity, flow characteristic, multistage fracturing technique and production pressure difference were analyzed. It is found that physical properties of reservoirs and development degree of effective sand bodies are the main factors controlling gas well productivity, and they have greater effect than the flow dominant term at the heel and toe of the horizontal well in an ideal model. The increase in production pressure difference aggravates the difference in gas production rate among fracturing sections in strongly heterogeneous reservoirs. The uneven distribution of induced fractures leads to different gas productivities of perforation clusters in the same fracturing section. Therefore, for multi-stage fractured horizontal wells, technical countermeasures such as optimization of perforation sections, differential stimulation of horizontal sections, and uniform fracture propagation by temporary plugging were proposed so as to improve the development effect of tight gas reservoirs.

Key words: Ordos basin, Yishaan slope, Sulige gas field, tight gas reservoir, heterogeneity, horizontal well, multi-stage fracturing, gas pro-duction profile
