摘要/Abstract

摘要： 复杂流体油气藏的流体性质依靠常规录井、测井手段难以识别,基于文昌X区油气藏的气测录井响应,提出一种先识别流体类型、再评价含油气丰度的快速识别技术。应用目标区23口井458层显示层的气测衍生资料建立3H解释模型、Bar图法及气测衍生参数散点图等复杂储层流体性质识别图板,达到快速识别流体类型的目的;应用气测数据,分组段统计气测特征参数异常倍数和VOL_C1,建立储层含油气丰度评价标准。该技术在文昌X区应用效果良好,与电缆取样、地层DST测试的吻合率达96 %以上,值得推广应用。

Abstract: The fluid properties of complex fluid hydrocarbon reservoirs are difficult to be identified by conventional mud logging and logging methods. Based on gas logging response of hydrocarbon reservoirs in Wenchang X area, a rapid identification technique is proposed to identify the fluid type first and then evaluate the hydrocarbon abundance. The gas logging derived data of 458 show layers of 23 wells in the target area were used to establish complex reservoir fluid property identification charts of 3H interpretation model, Bar diagram and gas logging derived parameter scatter diagram, so as to identify the fluid types of complex reservoirs quickly. Using gas logging data, the abnormal multiples of gas logging characteristic parameters and VOL_C1 are counted by formations and members, and the evaluation criteria of reservoir hydrocarbon abundance were established. This technology has good applied effects in Wenchang X area, and the coincidence rate with cable sampling and formation DST is more than 96%, which is worth popularizing.

Key words: gas logging, complex reservoir fluid, evaluation, 3H interpretation model, Bar diagram, gas logging derived parameter, scatter diagram, Wenchang sag
