Embodiment Construction

[0053]In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0054] This specific embodiment adopts following technical scheme: its establishment method is as follows:

[0055] For the cave-constant-volume model, the fractures only play a role of diversion, their storage properties are ignored, the elastic energy of the original formation water is considered, and the volume change of the cave-constant volume and the compressibility of rocks are ignored. Assume that the volume of the original cave type-constant volume is...

Abstract

The invention discloses a karst cave type-carbonate reservoir. The invention discloses a constant volume physical capacity indication curve interpretation model, and relates to the technical field ofreservoir geology and development. Establishment method comprises the following steps according to the constant volume body model, cracks only play a role in diversion, the storage performance of thecracks is ignored, elastic energy of an original formation water body is considered, and karst caves and caves are ignored. The volume change of the constant volume body and the rock compressibility are achieved; Karst cave type device The constant volume body model serves as a research target, and for oil reservoirs with different elastic energy, the influence of the energy provided by the same oil reservoir in different exploitation stages on the energy indication curve can be distinguished. Through the newly established energy indication curve model, the expression of formation pressure andcumulative liquid production can be derived, the driving energy of different elastic energy reservoirs can be qualitatively distinguished, and the geological reserves of different elastic energy reservoirs can be quantitatively calculated.

Description

Technical field: [0001] The invention relates to an interpretation model of a carbonate rock reservoir karst cave type-constant volume body energy indicating curve, and belongs to the technical field of reservoir geology and development. Background technique: [0002] Dissolved cave type-constant volume reservoirs are one of the most important reservoirs in carbonate reservoirs. At present, there are many methods to determine the geological reserves of this type of reservoirs. Most of the methods have certain defects, but can directly reflect The method of formation energy magnitude has not been seen in the literature. Therefore, it is necessary to re-establish a method that can directly reflect the formation energy and determine the geological reserves of the oil reservoir more accurately. Invention content: [0003] In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide an interpretation model for the energy in...
