DX10-5构造是一个处于断层上升盘、主体受两条呈右阶式雁列排列断层控制的低幅宽缓牵引背斜,从T60至T41层均有圈闭存在,T41以上层位该构造已经不存在。T41是一个小型自圈,T60至T42层均为受断层控制的断圈带自圈构造,经过加密解释,新增解释层位T42L。针对这一特点在应用传统录井方法的基础上,结合岩石热解分析、气相色谱地化分析技术,在油水层识别方面建立了PG与S2/PG关系图版,形成了储集层流体性质的地化综合评价方法。使该区块得的解释符合率得到了提高。
The DX10-5 structure is a low-lying wide-hysteretic anticline on the fault-rising plate, which is dominated by two right-echelon geologic alignment faults. Traps exist from T60 to T41 and above T41 No longer exists. T41 is a small self-circle, T60 to T42 are fault-controlled ring breaking with self-circle structure, after encryption to explain, the new interpretation of the level of T42L. Aiming at this feature, based on the traditional logging method and combined with rock pyrolysis analysis and gas chromatography geochemical analysis technology, a PG and S2 / PG chart has been established in oil-water layer identification to form the fluid properties of the reservoir Geo-synthetic evaluation method. The rate of interpretation of the block has been improved.
