【摘要】：為了滿足天然氣調(diào)峰、事故應(yīng)急和戰(zhàn)略儲備的需要,中國石油天然氣股份有限公司擬在長慶氣田開展儲氣庫群建設(shè),其中包括陜Y儲氣庫在內(nèi)的數(shù)座含硫氣藏儲氣庫。成功建設(shè)此類含硫氣儲氣庫需要合適的含硫氣藏儲氣庫注采工藝,而目前國內(nèi)外尚無成熟的含硫氣藏型儲氣庫工藝技術(shù)可以借鑒。因此,先期開展陜Y含硫氣藏儲氣庫地面注采工藝的研究尤為重要。本文通過分析陜Y儲氣庫地面注采工藝主要完成以下幾點研究內(nèi)容:(1)陜Y儲氣庫注入氣源是產(chǎn)品氣,不含雜質(zhì),而采出氣為含有H2S、CO2的未凈化天然氣,同時注采過程工況有很大不同。本文對此創(chuàng)新性的提出了注采雙管、注采氣井雙向計量的工藝,簡化了注采工藝流程,降低了工程投資。(2)在已知地層的破裂壓力的情況下,通過利用氣藏工程方法對注氣系統(tǒng)壓力節(jié)點分析,反推出注氣井口壓力。結(jié)合儲氣庫壓力運行范圍和地面配套設(shè)備及管網(wǎng)設(shè)計能力進行綜合考慮,得到了儲氣庫合理的注氣壓力。(3)通過分析陜Y儲氣庫采氣系統(tǒng)節(jié)點壓力的變化,以及水合物生成的條件的預(yù)測,提出了水平井兩級降壓,開工移動注醇,中高壓采氣,加熱節(jié)流,三甘醇脫水的地面工藝模式。(4)針對含硫氣藏儲氣庫H2S和CO2等氣體組分,在注采周期的變化規(guī)律進行了研究總結(jié),提出了出了適合陜Y儲氣庫的脫硫脫碳工藝。(5)經(jīng)過對儲氣庫壓縮機周期性強采強注、工況變化大、適應(yīng)能力強的工作特點的分析,選擇了適合陜Y儲氣庫的壓縮機配置方案,同時對壓縮機工況進行了校核。陜Y儲氣庫注采工藝的研究總結(jié)為長慶氣田以及國內(nèi)以后大規(guī)模酸性氣藏儲氣庫的建設(shè)提供了重要經(jīng)驗與技術(shù)支持。
[Abstract]:In order to meet the needs of natural gas peak shaving, accident emergency and strategic reserve, CNPC plans to build a gas storage group in Changqing gas field, including several sulfur-bearing gas reservoirs including Shaanxi Y gas reservoir. The successful construction of this kind of sulfur-bearing gas storage requires an appropriate injection and production process of the sulfur-bearing gas reservoir, but at present there is no mature sulfur-containing gas reservoir technology at home and abroad to be used for reference. Therefore, it is very important to study the surface injection and production technology of Shaanxi Y sour gas reservoir in advance. In this paper, the main research contents are as follows: (1) the injected gas source of Shaanxi Y gas storage reservoir is product gas without impurity, while the produced gas is unpurified natural gas containing H _ 2S _ 2 and CO _ 2, the main research contents of this paper are as follows: (1) the injected gas source of Shaanxi Y gas storage reservoir is product gas without impurity. At the same time, the working conditions of injection-mining process are very different. In this paper, the technology of dual pipe injection and gas injection and bidirectional measurement of gas injection well is put forward, which simplifies the injection and production process and reduces the project investment. (2) under the condition of known formation fracture pressure, By using gas reservoir engineering method, the pressure node of gas injection system is analyzed and the wellhead pressure of gas injection system is deduced. The reasonable gas injection pressure is obtained by considering the operation range of gas storage reservoir and the design ability of ground supporting equipment and pipe network. (3) the change of node pressure of gas production system in Shaanxi Y gas storage reservoir is analyzed. As well as the prediction of hydrate formation conditions, this paper puts forward the surface process model of two-stage depressurization, starting to move alcohol injection, medium-high pressure gas recovery, heating throttling, and dehydration of triethylene glycol in horizontal wells. (4) aiming at the gas components such as H _ 2S and CO2 in sulfur-containing gas reservoirs, The variation law of injection-production cycle is studied and summarized, and the desulphurization and decarburization process suitable for Shaanxi Y gas storage reservoir is put forward. (5) through the analysis of the working characteristics of gas storage compressor with periodic strong production and strong injection, the working conditions change greatly and the adaptability is strong. The compressor configuration scheme suitable for Shaanxi Y gas storage is selected, and the compressor condition is checked at the same time. The research on injection and production technology of Shaanxi Y gas storage reservoir provides important experience and technical support for the construction of Changqing gas field and large scale acid gas reservoir in China.
