雁木西油田白垩系沉积微相及储层研究
|
摘要
针对雁木西油田白垩系低阻油层受沉积相带及其断裂、构造和岩性等多种因素控制,在上部地层大套膏盐地层采用盐水泥浆钻井,测井信息应用难度增大,提出利用多种测井响应提取单渗砂层能量厚度信息,使其曲线形态、特征和数据大小能够集中反映相对高渗的单渗砂层最大沉积能量及厚度变化,有效克服了层段中几个成因相近薄砂层或砂泥互层中砂层累加厚度划分主体骨架砂体微相带的失误。利用地层倾角测井,确定了古水流方向、砂体延伸、层理构造和微相特征；结合单井相序、连井剖面相、平面沉积微相展布研究,重构了该区白垩系沉积模式,阐明了扇三角洲前缘水下辫状河道、浅水河道骨架砂体有利微相带的发育规模及分布范围。通过该区白垩系井径、自然伽马、密度、中子、声波测井曲线和岩性、孔隙度及其能量厚度统计,在目的层段提取单渗砂层沉积能量厚度下限标准,分析了水下辫状河道、浅水河道有利沉积微相带展布及其与油气富集的生、储、盖组合匹配关系。采用浅水河道微相控制K1S1期、水下辫状河道控制K1S2期储层精细评价解释,有效地圈定并阐明了新增油层有效厚度及其分布,为该区油田增储上产和调整挖潜提供了可靠依据。
In the Yanmuxi oilfield of cretaceous, the low resistivity reservoir is influent by sedimentary facies, fracture, structure and lithology, plus the upper gypsum stratum effects by the salty mud, logging information is difficult to use. Aim at this characteristic, in this paper we picked up single penetrability sand body thickness to by various logging methods to make the borehole log shape and data able to reflect the relatively high permeability largest sedimentary energy and its thickness difference. So it overcome the lapse that the total sand thickness of several genetic similar thin sand layer ro sand-clay layer to classify frame sedimentary sand distribution.We use the dip logger to determine the direction of flow, sand body extension, stratification structure and sedimentary characteristics. Combine the research of single well sedimentary system, bisect sedimentary and ichnography sedimentary, the depositional model is built. So underwater channel sand, shallow channel sand body in front of fan delta which is the favorable sedimentary micro-faces distribution.Through the statistic of diameter, natural gamma ray, density, neutrons, acoustic as well as lithologic and porosity features. The limiting of single penetrability sand thickness is built. In the aim layer we pick up sing penetrability sand sedimentary energy, so the relationship between the favorable faces and association of source-reservoir-cap rock where oil or gas is gathering. By that method we find out that, the K1S1 phase is controlled by shallow water faces, and underwater braid channel control the K1S2 phase. And effective thickness of pay both append and present distribution is made out. So our job give reliable basis to the reserve increasing and potential capacity seeking.
