【摘要】：天然氣水合物(以下簡(jiǎn)稱水合物)分別蘊(yùn)藏于海洋和陸地永凍土帶中,但前者的儲(chǔ)量約為后者的100倍。海洋環(huán)境中的大部分脈狀、塊狀水合物以及細(xì)粒沉積物中的水合物都屬于非成巖天然氣水合物,一般沒有像常規(guī)油氣藏和砂巖水合物儲(chǔ)層那樣穩(wěn)定的圈閉構(gòu)造。針對(duì)海洋非成巖水合物的物理特征、成藏特點(diǎn),依據(jù)水合物固態(tài)流化開采法的工藝流程,建立了世界首個(gè)海洋天然氣水合物固態(tài)流化開采實(shí)驗(yàn)室。該實(shí)驗(yàn)室定位于"全自動(dòng)化的白領(lǐng)型實(shí)驗(yàn)室",實(shí)驗(yàn)系統(tǒng)共分為大樣品快速制備及破碎、高效管輸、高效分離、快速檢測(cè)等模塊單元。該實(shí)驗(yàn)室的主體功能包括:(1)高效破巖能力評(píng)級(jí);(2)海洋天然氣水合物層流化試采攜巖能力評(píng)價(jià);(3)水合物非平衡分解規(guī)律及流態(tài)動(dòng)變規(guī)律評(píng)價(jià);(4)不同機(jī)械開采速率條件下水合物安全輸送;(5)井控安全規(guī)律模擬。該實(shí)驗(yàn)室的關(guān)鍵技術(shù)指標(biāo):工作壓力12 MPa、水平管長(zhǎng)度65 m、立管長(zhǎng)度30 m、管徑3英寸。該實(shí)驗(yàn)室能模擬1 200 m水深的全過程水合物固態(tài)流化開采工藝過程,是西南石油大學(xué)聯(lián)合中國(guó)海洋石油總公司、宏華集團(tuán)原始創(chuàng)新自主設(shè)計(jì)、自主研發(fā)的標(biāo)志性實(shí)驗(yàn)室。
[Abstract]:Natural gas hydrate (hereinafter referred to as gas hydrate) is located in the permafrost zone of the sea and land respectively, but the reserves of the former are about 100 times of that of the latter. Most of the veins, block hydrates and hydrates in fine-grained sediments are non-diagenetic natural gas hydrates, and there are generally no stable traps like conventional oil and gas reservoirs and sandstone hydrate reservoirs. In view of the physical characteristics and reservoir forming characteristics of marine non-diagenetic hydrates, the world's first laboratory for solid-state fluidization exploitation of marine natural gas hydrate was established according to the technological process of solid-state fluidization exploitation of gas hydrate. The laboratory is located in the "fully automatic white-collar laboratory". The experimental system is divided into several modules, such as rapid preparation and crushing of large samples, high efficiency pipe transportation, high efficiency separation, and rapid detection and so on. The main functions of the laboratory include: 1) high effective rock breaking capacity rating / 2) evaluation of rock carrying capacity in fluidization of marine natural gas hydrate layer. Evaluation of gas hydrate nonequilibrium decomposition law and fluid dynamic variation rule evaluation of different mechanical mining rate strips Simulation of well control safety law of hydrate safe transportation under the component. The key technical parameters of the laboratory are: working pressure 12 MPA, horizontal tube length 65 m, riser length 30 m, pipe diameter 3 inches. The laboratory, which can simulate the whole process of hydrate solid-state fluidization mining process with water depth of 1,200 m, is an iconic laboratory developed by Southwest University of Petroleum, China National Offshore Oil Corporation and Honghua Group.
