烃相态分析录井技术在东海新探区油气识别中的应用

Application of Hydrocarbon Spectrum Graphices Logging Technique in Oil and Gas Identification in the New Exploration Area of East China Sea

随着东海海域油气勘探的不断深入,勘探难度增大,部分探区油气成藏条件复杂。受限于储层岩性复杂、非均质性强及流体性质多变的影响,储层流体准确识别难度较大,而传统的录井、测井技术在识别中深层复杂流体的性质仍存在不足。为了解决东海探区流体评价难题,引入烃相态分析录井技术。该技术利用检测到的烃类物质组成以及含量的变化规律来定性、定量地快速评价储层的流体,通过在东海某新区块勘探作业中的实际应用,证实该技术具有参数丰富、分析速度快、仪器稳定性好等特点,有利于储层流体性质的快速识别,助力解决东海新探区的油气解释评价难题。

With the continuous oil and gas exploration in East China Sea,it becomes more difficult to conduct exploration work.The oil and gas accumulation conditions in some exploration areas are complex.Traditional logging and logging techniques still have limitations in identifying the properties of complex fluids in the middle and deep layers because of the complex reservoir lithology,strong heterogeneity and variety fluid properties.In order to solve the problem of fluid evaluation in East China Sea exploration area,the hydrocarbon spectrum graphices logging technique has been applied.This technology utilizes the detected changes in the composition and content of hydrocarbon substances to qualitatively and quantitatively evaluate reservoir fluids rapidly.It has been applied in the exploration of a new block in East China Sea and has been confirmed that it had the characteristics of multiple parameters,fast analysis speed,and good instrument stability.This benefits rapid identification of reservoir fluid properties and helps to solve the problem of oil and gas interpretation and evaluation in the new exploration area of East China Sea.
