【摘要】：頁(yè)巖氣藏有著獨(dú)特的地質(zhì)特征與成藏模式,具有強(qiáng)烈的非均質(zhì)性,其資源評(píng)價(jià)方法不同于常規(guī)油氣藏。本文以長(zhǎng)寧地區(qū)龍馬溪組頁(yè)巖氣資源潛力分析為研究對(duì)象,在調(diào)研國(guó)內(nèi)外頁(yè)巖氣資源評(píng)價(jià)方法的基礎(chǔ)上,針對(duì)頁(yè)巖氣聚集機(jī)理和特點(diǎn),提出6種適合于不同勘探開發(fā)階段的頁(yè)巖氣資源評(píng)價(jià)方法,包括成因法、容積法、含氣量法、類比法、EUR法和特爾菲法。依據(jù)頁(yè)巖資源評(píng)價(jià)方法,提出了6種資源評(píng)價(jià)參數(shù)取值方法,并建立和集成了多個(gè)頁(yè)巖氣參數(shù)圖版。然后通過全巖X衍射、有機(jī)碳、成熟度、物性、氮?dú)馕�、高倍顯微鏡和含氣性等實(shí)驗(yàn)手段,研究了長(zhǎng)寧地區(qū)龍馬溪組頁(yè)巖基本地質(zhì)特征。研究認(rèn)為研究區(qū)龍馬溪組頁(yè)巖埋深適中,有利于頁(yè)巖氣保存與開采；TOC含量高,有機(jī)質(zhì)類型好,成熟度適中,具備良好的生氣能力；孔滲性能好、密度低,含氣量高,具備良好的儲(chǔ)氣能力。龍馬溪組優(yōu)質(zhì)頁(yè)巖氣儲(chǔ)層厚度為20m-63m。根據(jù)研究區(qū)勘探程度、地質(zhì)特征和資料情況,選取了類比法、容積法和含氣量法進(jìn)行頁(yè)巖氣資源評(píng)價(jià),采用圖形數(shù)據(jù)取值、類比取值和公式取值3種方法確定了參數(shù)的選取,逐次進(jìn)行了單個(gè)方法估算。分析不同方法計(jì)算結(jié)果的可靠性,采用特爾菲法綜合計(jì)算研究區(qū)龍馬溪組優(yōu)質(zhì)頁(yè)巖段頁(yè)巖氣地質(zhì)資源量為22489.8×108m3,平均資源豐度為5.8×108m3/km2,可采資源量為3216×108m3,綜合表明研究區(qū)龍馬溪組資源潛力豐富,并認(rèn)為估算結(jié)果可靠性高、應(yīng)用效果好。
[Abstract]:Shale gas reservoir has unique geological characteristics, reservoir forming model and strong heterogeneity, and its resource evaluation method is different from that of conventional oil and gas reservoir.In this paper, the potential analysis of shale gas resources in Longmaxi formation in Changning area is studied. Based on the investigation of the evaluation methods of shale gas resources at home and abroad, the mechanism and characteristics of shale gas accumulation are discussed.Six methods for evaluating shale gas resources at different stages of exploration and development are proposed, including genetic method, volumetric method, gas content method, analogy method and Delphi method.According to the method of shale resource evaluation, this paper puts forward six methods for evaluating the parameters of shale gas, and establishes and integrates several maps of shale gas parameters.The basic geological characteristics of the shale of Longmaxi formation in Changning area were studied by means of X-ray diffraction, organic carbon, maturity, physical properties, nitrogen adsorption, high power microscope and gas-bearing properties.It is considered that the suitable depth of shale buried in Longmaxi formation in the study area is conducive to high TOC content, good organic matter type, moderate maturity, good pore permeability, low density and high gas content in shale gas preservation and exploitation.Good gas storage ability.The thickness of high quality shale gas reservoir in Longmaxi formation is 20m-63m.According to the exploration degree, geological characteristics and data of the study area, the shale gas resources are evaluated by analogy method, volume method and gas content method. The selection of parameters is determined by three methods: figure data, analogy value and formula value.A single method of estimation was carried out one by one.The reliability of the calculation results of different methods is analyzed.The geological resources of high quality shale gas in Longmaxi formation are 22489.8 脳 108m3, the average abundance is 5.8 脳 108m3 / km2, and the recoverable resource is 3216 脳 108m3.The comprehensive calculation shows that the Longmaxi formation in the study area is rich in potential resources, and the reliability of the estimated results is high.The application effect is good.
