Abstract

The invention discloses a control line-based stratigraphic structure fluctuation representation processing method and system. A stratigraphic control line is generated according to nodes of a target stratigraphic line; constructing an incidence relation between formation control lines and formation lines, and obtaining a formation line set corresponding to the formation control lines; adding an initial control point on a specified stratum control line, traversing the remaining stratum control lines, and adding an auxiliary control point at the same position as the abscissa of the initial control point; traversing the formation line and the sand body line, constructing an association relationship between control points on the formation control line and formation line nodes, and determining and recording each formation control point and a node corresponding to each formation line in the formation line set; and constructing a control point, stratum line node and stratum control line three-level editing mechanism to carry out stratum structure fluctuation form characterization. The invention provides a solution thought from local to overall, multi-stage quick adjustment schemes such as stratum fine adjustment, local trend adjustment, overall trend adjustment and the like are realized, the sand body form is highly constrained and maintained, and oil reservoir analysis can be accurately carried out.

Description

technical field [0001] The invention relates to the technical field of reservoir analysis, in particular to a control line-based method and system for characterizing and processing formation structure fluctuations. Background technique [0002] Reservoirs refer to the basic accumulation of oil in a single trap with the same pressure system. Reservoirs are divided into three categories according to the origin of reservoirs: structural reservoirs, stratigraphic reservoirs and lithologic reservoirs. Among them, structural reservoirs Oil and gas accumulation in structural traps formed by structural deformation (such as folds) or faults; oil and gas accumulations formed in stratigraphic unconformity barrier traps and stratigraphic overlapping traps are called stratigraphic oil and gas pools; oil (gas) Accumulated in the lithological pinch-out and sandstone lens traps formed by lateral changes in reservoir lithology due to changes in depositional conditions, it is called lithologi...
