摘　　要：喇嘛甸油田已进入特高含水开发阶段。通过分析该油田近3年的取心井水洗资料和新钻井测井资料，确定了水淹层解释精度偏低的影响因素、油层水淹后测井曲线响应特征及其匹配关系。在此基础上，根据不同区域、储层动用状况对水淹层解释精度进行了定性校正，建立了水淹层解释测井曲线重构方法和深侧向电阻率曲线恢复法，使水淹层解释精度达到81．5％。研究成果为喇嘛甸油田特高含水期剩余油挖潜提供了可靠依据。Lamadian Oilfield has reached the development stage of extra-high water cut, With the help of the data analyses for the watered coring wells and the logs from newly-drilled wells, the influencing factors on the above precision, the response characteristics of the well logging curves of these watered-out oil layers and their matching relations are determined. On the basis of the above, according to the developed status of different regions and reservoirs, the qualitative correction is conducted for the interpretation precision and moreover the reconstructed method for the well logging curves of the watered-out layers and the build-up approach for dee, p laterolog resistance curves are established, thus the precision has reached 81.5%. The study results have provided a reliable evidences for the remained oil tapping at extra-high water cut stage of Lamadian Oilfield.
