摘要/Abstract

摘要： 成岩作用在沉积岩形成演化过程中占有重要位置。由于不同盆地沉积及构造演化的差异性，导致其成岩作用也有不同的特点。以样品实验分析为基础，开展尼日尔Termit 盆地白垩系砂岩成岩作用研究，明确了该盆地白垩系砂岩成岩作用的主要类型及其对储层的影响；根据成岩现象、黏土矿物特征与变化规律、包裹体均一温度等多个方面对该盆地白垩系砂岩储层进行成岩阶段划分，认为研究区白垩系砂岩大多处于中成岩A 阶段，埋藏较浅的砂岩处于早成岩B 阶段。Termit 盆地白垩系砂岩的岩石类型是影响成岩作用的一个重要因素，由于该盆地白垩系砂岩以石英砂岩为主，石英颗粒的强支撑作用减弱了压实作用对储层的破坏，原生粒间孔是最为发育的孔隙类型，此外还发育少量粒内孔隙、粒间溶孔等孔隙。Termit 盆地不同区带白垩系砂岩储层的发育具有一定的差异，Fana 低凸起和 Yogou 斜坡储层相对较发育，储层物性好；Soudana 隆起带和Dinga 断阶储层物性差。Fana 低凸起具有很好的勘探潜力，从钻探结果中也得到了证实，是后续白垩系勘探的重点区带。

Abstract: The Dagang Oilfield has entered the middle and late stages of exploration and development. Scientific research work is encountering problems with the collation of huge volumes of project data, diversity of software applications, and difficulty in sharing results between independent teams. To improve the efficiency and quality of research, a unified platform is urgently needed for project progress control, task allocation, and results archiving to impose order on this project. Software integration based on the E&P Dream Cloud platform integrates business software and common tools such as GeoEast, GeoMap, Resform, Forward and wellbore integration tools in the cloud. It creates a research environment based on core business scenarios such as seismic interpretation of structures, research on characteristics of sand body distribution, prediction of reservoir lateral distribution, research on hydrocarbon accumulation, well logging evaluation, oil and gas bearing property evaluation, etc. Timely and accurate transmission of professional and production data to the Data Lake is enabled, as well as whole process operation and management of projects, quality control, and sharing of applications and results. Online collaborative research work has been carried out, including seismic structure interpretation and analysis, distribution characteristics of reservoirs and sand bodies, and controlling factors of hydrocarbon accumulation. This supports the transformation from traditional “structural oil exploration” to “lithologic oil exploration in main sand body belt” in the study area. The effect in practice has been remarkable, and has played an important role in demonstrating the capabilities of the E&P Dream Cloud platform.

Key words: E&, P Dream Cloud, cloud integration, collaborative research, business scenario, fine exploration
