【摘要】：有利储层预测是制约目前下古生界碳酸盐岩潜山勘探由山头向内幕开展的重要因素之一,以济阳坳陷平方王油田下古生界潜山为研究对象,利用元素地球化学、矿物学、岩心常规分析等多种技术方法,分析内幕储层储集空间成因类型,明确储层发育主控因素,最终建立储层发育改造模式。结果表明:下古生界发育大套不同类型的碳酸盐岩是内幕储层形成的物质基础,内幕储层发育原生孔隙、构造裂缝、溶蚀孔洞-裂缝3种类型的储集空间,3种储集空间类型决定了储层受控于岩石类型、构造改造、流体改造3种地质因素;岩石类型是基础性因素,不仅决定了原生孔隙的量,且进一步影响岩石抗溶蚀与构造裂缝发育程度;构造改造是关键性因素,构造裂缝与溶蚀孔洞-裂缝的发育呈明显的正相关性;流体改造是决定性因素,深部热液和有机酸联合溶蚀形成了大量孔洞、微孔、微裂缝,大大改善了储层物性。
[Abstract]:The prediction of favorable reservoir is one of the important factors restricting the exploration of carbonate buried hill in Lower Paleozoic from the hill to the inside at present. Taking the buried hill of lower Paleozoic in Jiyang depression as the research object, the element geochemistry is used. Mineralogy, conventional core analysis and other technical methods to analyze the genetic types of insider reservoir space, to determine the main control factors of reservoir development. Finally, the model of reservoir development and transformation is established. The results show that the lower Paleozoic developed a large set of different types of carbonate rock is the material basis of the formation of the inside reservoir, the inside reservoir developed primary pores and structural fractures. There are three types of reservoir space, I. e., solution voids and fractures, which determine that the reservoir is controlled by rock type, structural transformation and fluid transformation, and that the reservoir is controlled by three geological factors: rock type, structural transformation and fluid transformation. Rock type is a basic factor, which not only determines the amount of primary pores, but also further affects the corrosion resistance of rocks and the development of structural fractures. Structural transformation is the key factor, and there is a significant positive correlation between structural fractures and the development of dissolution voids and fractures. Fluid transformation is the decisive factor. A large number of pores, micropores and micro-fractures have been formed by the combined dissolution of deep hydrothermal solution and organic acid, and the physical properties of the reservoir have been greatly improved.
