| 摘 要： | 近年来在新疆塔里木盆地发现了超亿吨级的碳酸盐岩大型油气田,洞穴型碳酸盐岩储层是其非常重要的储层类型之一,而此类储层的有效性取决于洞穴中充填物及充填程度，由于此储层中的洞穴横向变化可延伸至几米甚至几十米，远远超过了仪器的探测深度，因此对它的充填程度及其充填物的有效识别仍是目前待攻关的难题。通过分析不同充填程度、不同充填物的洞穴在常规测井曲线、电成像和阵列声波图像上的响应特征以及交会图分析法来识别洞穴充填物的性质，并结合钻井、录井、试井及地震等方面的识别标志，将洞穴型储层划分为完全充填洞穴储层、半充填以及未充填洞穴储层。

| Abstract: | The large oil-gas oilfield, discovered in the Tarim Basin of Xinjiang, has more than 0.1 billion tons OOIP. Cave carbonate reservoir is one of very important reservoir types, the effectiveness of such reservoir depends on filling degree of cave, because of the reservoir’s horizontal distance can extend to a few meters or even dozens of meters, far exceeding the depth of the detection equipment, so it is still a technical puzzle to recognize effectively the infill and the filling degree in karst cave. The ancient caves’ logging response characteristic with different filling degree and filler in the conventional well logs, electric array acoustic imaging, array sonic image and cross-plot analysis to identify the character of the cave filling are analyzing in conjunction with identifier such as drilling, logging, well testing and seismic in the paper. It is concluded that the cave reservoirs can be divided into completely filled, half filled and unfilled types according to the analysis. |
