Method for seismic monitoring of hydrocarbon field development in water areas

摘要

1. A method of seismic monitoring of the process of developing a hydrocarbon field in water areas, including conducting three-dimensional seismic exploration and building a reservoir model based on it, predicting the orientation of subvertical fracture systems and designing the location of production and injection wells, placing stationary seismic streamers at the bottom of the water area, recording elastic seismic surveys fluctuations from artificial sources and control of the process of developing a hydrocarbon field by dyne physical and kinematic changes in the recorded oscillations during processing of seismic surveys, characterized in that prior to the start of drilling the designed horizontal section of the well, a mobile arrangement of seismic skids is placed on the bottom along a radially different-azimuth observation system at the research object with a center located above the horizontal section of the well, microseismic vibrations are recorded during drilling excited by a bit at the bottom of the well, during the processing of which according to dynamic and kinematic characteristics sticks are determined by the anisotropic properties of the medium in the drilling zone, the orientation of the subvertical fracture systems is refined, and three-dimensional reservoir models are corrected, and after completion of the well drilling, the seismic line arrangement is dismantled and moved to a new research object. 2. The method according to claim 1, characterized in that during the hydraulic fracturing process microseismic vibrations are recorded, three-dimensional coordinates of their sources are determined and an additional three-dimensional model of the reservoir and the orientation of the fracture system are specified.
