碳酸盐岩潜山录井快速评价技术

碳酸盐岩潜山是冀中地区油气勘探主要目的层之一,其特点是储集类型复杂、非均质性强.针对碳酸盐岩储层快速识别与储层物性评价开展了研究,完善了碳酸盐岩岩性特征、工程特征储层识别评价方法,建立了功指数储层识别、物性评价方法与评价标准,实现了储层快速识别与评价.在碳酸盐岩潜山多口井中应用取得良好成效,目前储层识别与评价符合率大于85%.为综合录井仪深入推广奠定了良好基础.

Fast evaluation technology for well logging in carbonate reservoirs

Rapid identification and evaluation of reservoir properties were studied and the method of lithologic engineering feature identification and evaluation was improved. Reservoir identification as well as physical property evaluation methods and criteria was established by using work index, and consequently the rapid reservoir identification and evaluation was achieved. The method worked well in many wells in carbonate buried hill reservoir, and the coincidence rate in present came to more than 85%.It laid a good foundation for further promotion of composite log unit.
