Hu 7 South In Strongly Heterogeneous Reservoir Strata Of Optimization, Reorganization, Technical And Economic Boundaries

This article carries on the study on the serious anisotropic Hu 7 south fault blocks high contains water the time to subdivide the development engineering, mainly carried out the reservoir anisotropism research, the distribution rule research of reservoir high permeability belt, the different grading condition the oil layer use condition and the use state research, the development formation optimization reorganization research, high contains water time development economic limit research and so on.The thesis has obtained following five aspects understanding: 1. Systematic describe to the Hu 7 south fault blocks levels in anisotropism, plane anisotropism and the level anisotropism, fonned the system approach to describe macroscopic heterogeneity of HuQing oil field, has expounded the distributed rule of the macroscopic heterogeneity; 2. through the research on the distribution law of reservoir high permeability belt to establish lithological character of high permeability belt, the electrical standard, has studied its change rule; And established the recognition methods; 3. through the multilayered water-oil displacement experiment obtained: (1) When single-layer picks, the permeability size is not big influent to the final recovery ratio. (2) Under different combination when water-oil displacement relative high permeability regardless of under what kind of combination, all can first the water drive breakthrough also the good use, but lowly infiltrates the level to deliver the characteristic to affect in a big high permeability belt, level grading bigger, lowly infiltrates the level use condition to be worse. (3) the certain displacement pressure is the key factor to the reservoir use. (4) The penetration coefficient grading is affects the multi- lamination note to gather picks the development effect the most primary factor, the next is combination layer and mean permeability; 4. to the economical well pattern density, the adjustment well economic limit, the measure economic limit, the customs police economic limit has conducted the research; 5. proposed the reorganization subdivides technical standard.
