摘要/Abstract

摘要： 针对姬塬北地区延长组勘探程度低且勘探潜力认识不足的问题,利用钻井、分析化验等资料,对姬塬北延长组长₆—长₈油层组烃源岩条件、储层条件、成藏模式以及油藏特征等进行了分析研究。研究表明:姬塬北地区长₇油层组烃源岩发育,长₇³底部暗色泥岩为有效烃源岩;有机碳含量普遍大于2%,氯仿沥青“A”平均为0.189%,生烃潜量S₁+S₂平均为13.01 mg/g,有机质丰度高,有机质类型以Ⅰ型为主,具有原油生成的基础物质来源;长₆、长₈油层组储层砂体平均厚度大于10 m,孔喉组合关系主要为小孔隙微细喉与微孔喉,少量中孔中细喉,孔隙度主要为8%～12%;因河道纵横向迁移摆动,形成了有利的储盖组合,构成岩性及物性圈闭;油藏分布受烃源岩展布、砂体分布及储层发育程度的叠合分布状态控制。综合认为该区具有较大的石油勘探潜力,确定峰201、峰11井区为该区最有利的叠置勘探目标区。该研究对姬塬北地区延长组下一步的勘探开发具有指导意义。

Abstract: In view of the relatively weak exploration and poor understanding of the exploration potential of the Yanchang Formation in the northern Jiyuan area, the hydrocarbon source rock conditions, reservoir conditions, accumulation mode and reservoir characteristics of the Chang₆-Chang₈ pay zones of Yanchang Formation in the northern Jiyuan area were analyzed and studied with drilling, analysis and laboratory data. It was found in the study that hydrocarbon source rock was developed in the Chang₇ pay zones of Yanchang Formation in the northern Jiyuan area, the dark mudstone at the bottom of Chang₇³ was effective hydrocarbon source rock; the organic carbon content was generally greater than 2%, the average content of chloroform bitumen "A" was 0.189%, the average of hydrocarbon generation potential S₁+S₂ was 13.01 mg/g, the organic matter abundance was high, the organic matter was dominated by Type I with basic source for petroleum generation; the average sand thickness of Chang₆ and Chang₈ pay zones was more than 10m, and the pore-throat combination was mainly small pore + micro-throat, micro pore + micro throat, locally medium pore + medium throat, and the porosity was mainly 8% to 12%; because of the longitudinal and transverse migration of the river channel, favorable reservoir-capping assemblage was formed, constituting lithologic and physical traps; the reservoir distribution was controlled by superposition of hydrocarbon source rock spreading, sand facies distribution and reservoir development. It was generally considered that this area had great oil exploration potential, and Wellblocks Feng 201 and Feng 11 were identified as the most favorable stacked exploration target areas in the area. The study is of guiding significance for the next oilfield exploration and development in the Yanchang Formation, the northern Jiyuan area.
