- Abstract
In order to clarify the main controlling factors of dual porous medium reservoir production in Dongdaohaizi Sag and formulate the productivity prediction scheme, the configuration relationship between reservoir matrix parameters, fracture parameters and meter liquid production was studied by comprehensively using the data of drilling coring, thin section identification, conventional logging, imaging logging and production test. On this basis, the matrix comprehensive index f 1 and fracture effectiveness index f 2 were constructed by using correlation analysis method and sensitive parameter analysis method, and the productivity prediction bubble chart based on f 1 and f 2 index was established. The results show that the yield in the study area is jointly controlled by matrix and fracture. Permeability, gravel content, clay content and average capillary radius are the matrix main controlling factors of production, fracture width and the angle between fracture strike and the direction of maximum horizontal principal stress are the main controlling factors of production, and the control effect of fracture on productivity is stronger than that of matrix. The productivity prediction bubble chart based on f 1 and f 2 indexes has a good relationship with the liquid production per meter. The liquid production capacity of the reservoir in the study area is obviously divided into high production, middle production and low production. Verified by the oil test results of 15 layers of well 9, the coincidence rate of the prediction chart is 93. 3%, which provides a basis for the recheck of old wells and the productivity prediction of new wells in the study area.
