摘要：采油（氣）工程方案是油（氣）田開發(fā)方案的重要組成部份和方案實(shí)施的核心，它通過對產(chǎn)油（氣）井和注入井采取一系列工程技術(shù)措施，達(dá)到經(jīng)濟(jì)、有效地提高油氣井產(chǎn)量的目的，是實(shí)現(xiàn)油田開發(fā)指標(biāo)和完成原油生產(chǎn)任務(wù)的重要工程技術(shù)保證。我國新增探明石油儲量在保持高基值穩(wěn)定增長的同時(shí)，儲量品位總體呈下降趨勢，低滲、薄層、分散區(qū)塊等邊際油氣藏將會成為未來油氣田開發(fā)的主體。必須運(yùn)用新技術(shù)、新手段進(jìn)行油氣田開發(fā)才能保證油氣產(chǎn)能的穩(wěn)步提升。人工水力壓裂是低滲透油氣藏增產(chǎn)的重要手段，其裂縫導(dǎo)流能力直接影響了壓后的產(chǎn)量。本設(shè)計(jì)根據(jù)12-86井的油藏特點(diǎn)，分別進(jìn)行不壓裂和進(jìn)行壓裂兩種情況下不同生產(chǎn)階段下產(chǎn)能的預(yù)測，進(jìn)行舉升參數(shù)的生產(chǎn)模擬，并設(shè)計(jì)出其生產(chǎn)參數(shù)和管柱結(jié)構(gòu)。通過對比發(fā)現(xiàn)，壓裂井的產(chǎn)能遠(yuǎn)大于未壓裂井產(chǎn)量，設(shè)計(jì)結(jié)果為12-86井壓裂投產(chǎn)采氣工程方案，該方案對指導(dǎo)該井高效生產(chǎn)具有參考價(jià)值。 關(guān)鍵詞：采油；采氣；方案；低滲透；壓裂
Abstract：Oil (gas) recovery scheme is the oil (gas) field development plan form an important part of the implementation of the scheme and core, it takes a series of engineering technology measures on the oil(gas) well and injection well to economy, effectively improving the purpose of oil and gas well production, is the important engineering technology guarantee to finish the oil field development task of crude oil production. With our country proven oil reserves grows in height, reserves grade overall declined, low permeability, thin bed, scattered block such as bound oil and gas reservoir will become the main body in the follow oil and gas field development. As the result, new technology and measure must be used to guarantee the production increased by oil and gas development. Artificial hydraulic fracturing is the most important step for low permeability reservoir, the fracture flow capacity directly affects the production after fracturing. According to the reservoir characteristics of 12-86 well, two production forecasts of are not fracturing and fracturing had be done, simulated the lifting parameter and designed both the producing parameter and pipe composition. By coMParing the results, fracturing well produces much more gas than the not fracturing well, so we designed a fracturing well gas recovery scheme, it would guide the well has a high effective production with reference value. Key words：Oil recovery; Gas recovery; Scheme; Low permeability; Fracture. |
