Discussion about pattern of water flooding development in multi-well fracture-cavity units of carbonate fracture-cavity reservoir in Tahe oilfield
摘要
Abstract
During the early stage of the test of water flooding development of multi-well fracture-cavity units in carbonate fracture-cavity reservoir in Tahe oilfield, it emerged some problems such as few efficient well groups, short efficient period and very fast water cut. In accordance with these problems, based on the systematic analysis of the water flooding test early stage and laboratory research, this paper puts forward the pattern of water flooding development of multi-well fracture-cavity units of carbonate fracture-cavity reservoir, which is intended to keep pressure, multi-stage and stereoscopic water flooding. The development of keeping pressure refers to keep the pressure of reservoir to slow down the decline rate caused by the energy decline and to restrain the bottom water coning. The multi-stage development refers to adopt different waterflood pattern, injection-production parameter and matching technology at different stage of water flooding development, it should increase the water injection rate to test the connectivity and construct the injection-production relation before water flooding effect appears, and it should adopt moderate waterflood until the water flood effect become serious, and increase water injection rate for cyclic water flooding and adopt reversing the direction of water injection well and profile control at the later stage. The development of stereoscopic water flooding refers to set up stereoscopic injection-production pattern according to development rule of fracture and cavity, the condition of distribution of residual oil and connectivity, it should adopt the water flooding ways and matching technologies of bidirectional or more directional injection, separated layer water injection, low injection and high production and fracture injecting and cavity production.关键词
