【摘要】：我國(guó)石油企業(yè)處于復(fù)雜多變的國(guó)內(nèi)外宏觀環(huán)境和石油市場(chǎng)環(huán)境中，面臨油田資源稀缺性、市場(chǎng)局限性、環(huán)境制約性、成本遞增性和收益遞減性的發(fā)展規(guī)律等現(xiàn)實(shí)問題，為適應(yīng)不斷變化的環(huán)境，只有采取高效率、低成本的可持續(xù)發(fā)展道路。而油藏評(píng)價(jià)工作作為連接勘探開發(fā)重要的一環(huán)，為了提升油藏評(píng)價(jià)的準(zhǔn)確性，保證油氣勘探開發(fā)的效率，滿足油藏評(píng)價(jià)工作的不同要求，有必要在油藏評(píng)價(jià)工作開展之前進(jìn)行油藏評(píng)價(jià)方案優(yōu)選，這對(duì)勘探開發(fā)成本控制與提升探明經(jīng)濟(jì)可采儲(chǔ)量有重要意義。 本文從油藏評(píng)價(jià)方案多屬性入手，梳理了油藏評(píng)價(jià)方案多屬性優(yōu)選基礎(chǔ)理論，構(gòu)建了涵蓋經(jīng)濟(jì)效益、風(fēng)險(xiǎn)、生態(tài)環(huán)境和社會(huì)效益的多層次指標(biāo)體系。針對(duì)油藏評(píng)價(jià)方案屬性重要性判斷的不確定性，采用層次分析法對(duì)油藏評(píng)價(jià)方案多屬性優(yōu)選中的評(píng)價(jià)指標(biāo)進(jìn)行賦權(quán)，并將層次分析法在模糊環(huán)境下擴(kuò)展，采用三角模糊數(shù)進(jìn)行比較判斷，，得出權(quán)重。考慮油藏評(píng)價(jià)屬性值模糊性特點(diǎn)，將油藏評(píng)價(jià)屬性值擴(kuò)展為三角模糊數(shù)，構(gòu)建了基于灰色關(guān)聯(lián)分析的多屬性優(yōu)選模型。結(jié)合具體某油田區(qū)塊五個(gè)方案對(duì)油藏評(píng)價(jià)方案進(jìn)行多屬性優(yōu)選實(shí)證分析。
[Abstract]:The petroleum enterprises of our country are in the complex and changeable macroscopical environment and the petroleum market environment at home and abroad. They are faced with the development law of oil field resource scarcity, market limitation, environment constraint, increasing cost and decreasing income, etc. In order to adapt to the changing environment, the sustainable development path with high efficiency and low cost should be adopted. As an important link between exploration and development, reservoir evaluation can improve the accuracy of reservoir evaluation and ensure the efficiency of oil and gas exploration and development. To meet the different requirements of reservoir evaluation, it is necessary to select the reservoir evaluation scheme before the reservoir evaluation work is carried out, which is of great significance to the cost control of exploration and development and the promotion of proven economic recoverable reserves. Starting with the multiple attributes of reservoir evaluation scheme, this paper combs the basic theory of multi-attribute optimal selection of reservoir evaluation scheme, and constructs a theory that covers economic benefits and risks. The multi-level index system of ecological environment and social benefit. In view of the uncertainty of attribute importance judgment of reservoir evaluation scheme, AHP is used to empower the evaluation index in multi-attribute optimal selection of reservoir evaluation scheme. The analytic hierarchy process (AHP) is extended in the fuzzy environment, the triangular fuzzy number is used to compare and judge, and the weight is obtained. Considering the fuzziness of reservoir evaluation attribute value, the reservoir evaluation attribute value is extended to triangular fuzzy number. A multi-attribute optimal selection model based on grey correlation analysis is constructed, and an empirical analysis of multi-attribute optimal selection of reservoir evaluation scheme is carried out in combination with five schemes of a specific oilfield block.
