摘要

川中安岳气田震旦系灯影组灯四上亚段普遍发育硅质岩,其对储层岩溶改造的影响尚不明确,有必要对其开展研究。为此,基于岩性、测井响应特征,进行了详细的岩心、薄片观察描述,利用硅质岩基本特征、储层对比图以及硅质岩平面图,开展川中龙女寺地区灯四上亚段硅质岩对储层岩溶改造影响的研究。结果表明:研究区硅质岩主要为藻纹层硅质岩、纯硅质岩和含云硅质岩;硅质层在灯四上亚段分为2段,硅质层上下储层良好,平面上硅质岩厚度向东北以及东南方向减薄;硅质岩因桐湾运动产生了裂缝,并遭受溶蚀扩大,无法阻挡岩溶流体下渗;断层切穿硅质层对岩溶储层的改造无影响,因此,硅质岩对储层岩溶改造影响较小。该研究成果为台内龙女寺地区寻找储层发育有利区奠定了基础。

Abstract

The siliceous rocks are commonly developed in the upper sub-section of the Fourth Member, Sinian Dengying Formation, Anyue Gasfield in central Sichuan, and their influence on reservoir karstification is still unclear, so it is necessary to conduct a corresponding study. For this reason, based on lithology, logging response characteristics, the cores and slices were described in details through observations, the study of the influence of siliceous rocks on reservoir karstification in the upper sub-section of the Fourth Member, Dengying Formation, in Longnyusi Area of Central Sichuan was carried out using basic characteristics of siliceous rocks, reservoir comparison diagram and siliceous plan, and the results show that The siliceous rocks in the study area are mainly algal laminated siliceous rocks, pure siliceous rocks and dolomitic siliceous rocks; the siliceous bed is divided into 2 sections in the upper sub-section of the Fourth Member, Dengying Formation, and the reservoirs above and below the siliceous bed are in good conditions, and the thickness of the siliceous rocks can be seen on the plane to be thinned to the northeast as well as to the southeast; the siliceous rocks are fractured by the Tongwan movement and suffer from dissolution enlargement, which cannot block the karst fluid infiltration; the fault cutting through the siliceous bed has no effect on the stimulation of the karst reservoirs. Therefore, siliceous rocks have less effect on the reservoir karstification. The research results have laid a foundation for finding favorable areas for reservoir development in the Longnyusi area within the platform.

Key words： Dengying Formation; siliceous rocks; reservoir; karst action; Sinian System; Longnyusi Area; Anyue Gasfield
