Embodiment Construction

[0051] Below according to accompanying drawing, the system of the present invention is described in detail (seeing Fig. 3).

[0052] From the crude oil degassed viscosity 111, crude oil density 112, and dissolved oil-gas ratio 113 in the basic parameter unit 11, the oil reservoir crude oil viscosity 121 in the intermediate calculation parameter unit 12 can be calculated by the method program set (see method 1); by the oil reservoir crude oil viscosity 121 obtain the specific oil recovery index 123 in the intermediate calculation parameter unit 12 by the permeability 115 in the basic parameter unit 11 (see method 3); obtain the dissolution coefficient 122 (see method 2) by the dissolved oil-gas ratio 113 and the well depth 114; The dissolution coefficient is 122, the initial water cut is 116, and the reasonable pump pressure is 124 (see method 4); the initial water cut is 116, and the crude oil density is 112, and the specific gravity of the wellbore mixture is 125 (see method 5...

Abstract

The invention relates to an oilfield development decision-making system applied to the petroleum exploitation field. Firstly, basic decision-making parameters are automatically collected or artificially recorded into a basic parameter unit 11; then a middle parameter calculating unit 12 selects oil-reservoir engineering methods from a method program collection 23 to perform calculation or selects map-board laws and standard tables from a law standard warehouse 22 to perform deduction; finally, in a final result data unit 13, analog is performed on the obtained decision-making result and similar developed oilfield examples searched from an oilfield development example warehouse 21 to judge the rationality of the decision-making result. The decision-making result is then exhibited on a comprehensive decision-making result display screen 3. On the large screen, the parameters are adjusted on spot. The real-time dynamic adjustment is done comprehensively with reciprocally automatic and artificial methods until a final decision-making result is confirmed. A decision-making knowledge base integrating expert experience, law standards and oilfield development examples is created and the intelligent design of new-area planning proposals and new-area productivity construction proposals is realized.

Description

technical field [0001] The invention relates to an oilfield development decision-making system applied in the field of oil exploitation. Background technique [0002] Oilfield development is a concealed technical project with the characteristics of high input, high output, high risk and irreversibility, so scientific decision-making is particularly important. At the same time, oilfield development is also a highly professional and practical field. The oilfield development experience accumulated by some outstanding experts in long-term mining practice is a very valuable asset. How to summarize, continue, promote and utilize the valuable experience of experts, It is an urgent problem to be solved at present. As far as the Shengli Oilfield is concerned, as of 2006, the proven reserves were 4.61827 billion tons. During the "Tenth Five-Year Plan" period, the average annual production reserves were more than 90 million tons. Hundreds of plans need to be made, and each development...
