Abstract

An optimal adjustment method a high-dip oil reservoir is disclosed. Sufficient development dynamic data, thorough study of geological structure and clear division of substrata are fully utilized to carry out geological comprehensive study and reservoir engineering study. Combined with pilot test results, the complete numerical simulation results of the whole reservoir are obtained, so that the distribution of undeveloped remaining oil can be obtained directly according to the numerical simulation results, and a sufficient theoretical basis is provided for the secondary development. The methodbrings convenience to directly arrange the adjustment well pattern in the remaining oil distribution dense area, avoids the problem that the adjustment wells are repeatedly arranged or arranged too little, solves the problem that the prior art lacks the overall, reasonable and fully implementable development strategy for the old oilfield with high dip angle, and realizes the purpose of providing the overall layout idea for the secondary start of the old oilfield with high dip angle.

Description

technical field [0001] The invention relates to the field of secondary development of low-pressure reservoirs, in particular to a method for optimizing and adjusting high-dip reservoirs. Background technique [0002] Globally, for some old oilfields, after a hundred years of development, they still have great development potential. However, so far, the development is still dominated by natural energy development, and piecemeal efforts and production increase have encountered bottlenecks. Due to the extremely long development time of this type of oilfield, the formation energy is extremely low, and the formation pressure is ultra-low pressure. Moreover, because these old oilfields all have the problem of knocking and fragmentation, it is difficult to arrange the adjustment wells for secondary development as a whole, and there is a lack of an overall, reasonable, and comprehensively implementable development strategy to guide. Especially for high-dip oil reservoirs, in the pr...
