摘　　要：火山岩油气藏是目前国内外开采难度比较大的油气藏类型之一。近些年,准噶尔盆地西北缘石炭系探明石油地质储量1.4×10^8t,并建成了规模产能,为石炭系油气藏的开发奠定了很好的实践基础。准噶尔盆地西北缘金龙10井区是典型的石炭系火山岩油气藏,其储层具有岩性种类繁多、孔隙结构复杂、非均质性强的特点,明确其产能特征对油藏开发中后期研究产能控制因素和分布有良好的指导作用。利用钻井、测井、录井、岩心、地震等静态资料,发现该区火山岩储层储集空间主要以溶蚀孔隙和次生裂缝为主。结合生产监测及试油试采等动态资料,开展油藏产能特征研究,得出4种产能类型:产能稳定型、底水锥进产液稳定型、产能衰竭型、无产能型。进一步分析产能控制因素,结果表明油井产能主要受孔隙-裂缝发育情况、构造位置、边底水以及压裂规模等因素的控制。Volcanic oil and gas reservoir is one of the most difficult reservoirs both domestic and overseas.In recent years,the proven petroleum geological reserves of the Carboniferous in the northwestern margin of the Junggar Basin are 140×106 t,and large-scale production capacity has been built,laying a good foundation for the development of Carboniferous oil and gas reservoirs.Well Jinlong 10 which is in the northwestern margin of the Junggar Basin is a typical Carboniferous volcanic reservoir.Its reservoirs are characterized by extensive lithology,complex pore structure and strong heterogeneity.Ensuring the characteristic of studied reservoir has a good guiding role for studying later part of production capacity controlling factors and distribution.Based on the static data such as drilling,logging and core samples,it has been found that the reservoir space is mainly composed of dissolution pore and secondary fracture.The reservoir capacity characteristic has been carried out by production monitoring,oil test and other dynamic data in this paper.Four types of production capacity has been yielded including:stable production,bottom water cone into the liquid stable type,capacity failure type,no capacity type.The results show that the oil well productivity is mainly controlled by factors such as pore-fracture development,tectonic location,bottom water and fracturing scale.
