【摘要】：水力噴砂射孔壓裂技術(shù)是集合了射孔、壓裂、自動(dòng)隔離于一體,區(qū)別于傳統(tǒng)的新型增產(chǎn)技術(shù)。它適用于低滲透油藏直井、水平井改造,能較為準(zhǔn)確地在預(yù)定層位造縫,無(wú)需機(jī)械封隔,自動(dòng)水動(dòng)力封隔,成本低、節(jié)約時(shí)間、施工安全可靠。2001年哈里伯頓公司率先利用了水力噴砂射孔壓裂技術(shù)對(duì)低滲透油藏進(jìn)行了增產(chǎn)改造。該技術(shù)是利用高速高壓攜砂壓裂液對(duì)井壁進(jìn)行射孔,打通地層與井筒間的通道,隨后加大壓裂液的流量并使其進(jìn)入縫隙并繼續(xù)增壓擴(kuò)展,從而在地層中形成填砂裂縫。在美國(guó)、加拿大等國(guó)家,已有大量的油井運(yùn)用水力噴射壓裂技術(shù)進(jìn)行了處理,產(chǎn)量得到明顯提高。我國(guó)也積極開(kāi)展了對(duì)水力噴砂射孔壓裂方面的研究。本文根據(jù)理論研究,確定了試驗(yàn)研究的內(nèi)容和相關(guān)的實(shí)驗(yàn)設(shè)備。具體對(duì)噴嘴材料、射流速度、磨料濃度和排量等參數(shù)進(jìn)行實(shí)驗(yàn),并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行分析和總結(jié),也對(duì)噴射壓裂階段參數(shù)進(jìn)行了設(shè)計(jì),最后根據(jù)水力噴射壓裂參數(shù)的相關(guān)變化規(guī)律,制作了計(jì)算模板,便于現(xiàn)場(chǎng)應(yīng)用。長(zhǎng)久以來(lái),人們對(duì)于水力噴射壓裂工藝已經(jīng)運(yùn)用很多,如何更好地對(duì)工藝參數(shù)進(jìn)行優(yōu)化配比,還有待于更多的研究和實(shí)踐。本文研究的目的和意義就是通過(guò)模擬實(shí)驗(yàn),更好地了解影響水力噴砂射孔壓裂的因素,確定出最合理的參數(shù),更好地為現(xiàn)場(chǎng)施工提供參考依據(jù),從而達(dá)到增產(chǎn)的目的,現(xiàn)場(chǎng)試驗(yàn)證實(shí)了室內(nèi)實(shí)驗(yàn)研究和設(shè)計(jì)方案是可行的。
[Abstract]:Hydraulic sand blasting perforation fracturing technology is a new type of production increasing technology, which combines perforation, fracturing and automatic isolation. It is suitable for the reconstruction of vertical wells and horizontal wells in low permeability reservoirs. It can make fractures accurately at predetermined layers without mechanical sealing, automatic hydrodynamic sealing, low cost and time saving. In 2001, Halliburton Company took the lead in making use of hydraulic sand blasting and perforation fracturing technology to increase production and reconstruct low permeability reservoir. This technique uses high speed and high pressure sand carrying fracturing fluid to perforate well wall, open the passage between formation and wellbore, then increase the flow rate of fracturing fluid and make it enter the crevice and continue to expand under pressure, thus forming sand filling fracture in formation. In the United States, Canada and other countries, a large number of wells have been treated with hydraulic injection fracturing technology, the production has been significantly improved. The research on hydraulic sand blasting perforation fracturing has also been carried out actively in China. According to the theoretical research, the content of the experimental research and related experimental equipment are determined in this paper. The parameters such as nozzle material, jet velocity, abrasive concentration and displacement are tested, and the experimental results are analyzed and summarized. The parameters of jet fracturing stage are also designed. Finally, according to the related variation rule of hydraulic jet fracturing parameters, a calculating template is made, which is convenient for field application. For a long time, the hydraulic jet fracturing process has been used a lot, how to better optimize the process parameters, still needs more research and practice. The purpose and significance of this study is to better understand the factors affecting hydraulic sand blasting perforation fracturing, to determine the most reasonable parameters, and to provide reference basis for field operation, so as to achieve the purpose of increasing production. The field test proves that the indoor experimental research and design scheme is feasible.
