双重介质油藏基质动用程度及规律
Producing degree and law of matrix in dual-porosity reservoir
摘要
Abstract
The matrix producing mechanism, degree and influencing factors in dual-porosity reservoir were studied by numerical simulation method. Since the software of ECLIPSE can not calculate the matrix production, a new method for calculating the matrix cumulative oil production using saturation change was proposed. The concept of matrix contribution rate was introduced to research the matrix producing degree. The effect of size index, matrix permeability, fracture permeability, water injection rate on the matrix contribution rate of water flooding was analyzed. The results show that the degree of fracture development is the main factor affecting the matrix producing degree. The more the fracture developed in the reservoir, the more obvious the effect of imbibitions oil-drain in matrix and the higher the matrix contribution rate is. The higher matrix permeability, the higher matrix contribution rate is. Fracture permeability has relative small effect on the matrix contribution rate.The lower water injection rate, the better matrix imbibitions oil-drain effect is.关键词
