水淹层地化录井评价技术在G18块中的应用

The Application of Geochemical Logging Evaluation Technology in Block G18

摘要: 辽河油田G18块莲花油层，储层物性较好，经过多年的注水开采，已经进入了高含水期，剩余油在平面上和空间上较为分散。以莲花油层开发地质难题为出发点，通过开展储层地化录井技术分析，运用岩石热解和热解气相色谱数字化技术，建立莲花油层解释评价图版，最终实现储层含油性评价，为开发方案的制定和调整提供技术支持。

Abstract: In Lianhua reservoir of block G18 in Liaohe oilfield, the reservoir property was better, after years of water flooding, it has entered a period of high water content, and the remaining oil was dispersed in the plane and space. Taking the geological development problems in Lianhua reservoir as a starting point, by analyzing reservoir geochemical logging technology, rock pyrolysis and pyrolysis gas chromatography technologies are used to set up the interpretation evaluation chart. Finally the oil-bearing property of the reservoir is evaluated, which provides the technical support for the formulation and adjustment of development program.
