摘要：

文章利用钻井、测井以及生产资料，通过油藏剖面图和油层厚度图的编制，确定了研究区油水边界，明确了研究区油层富集状态，并重新核算了研究区油气资源量。研究认为馆陶油层是块状边顶水油藏，部分区域发育底水。馆陶组油藏整体呈近似不规则的椭圆形和圆形，油层中部较厚，四周逐渐变薄，地层岩性对其分布影响较小，缺少明显的盖层，并且没有统一的油水界面。由岩石组分及其结构的变化导致的地层物性降低是油藏被封阻的主要原因。根据实际吞吐生产井、SAGD生产井和井温监测资料，提出井位部署的安全界限为距边水150 m。

Abstract:

This paper, based on drilling wells, logs and production data, compiles oil reservoir cross sections and oilbearing thickness map, determines the oilwater contact and oil concentration status, and remeasures the oilgas resource. Guantao oilbearing bed is a massive edge top water reservoir with partially bottom water, approximately in irregular oval or to round shape, thicker in the central, attenuate to the surrounding borders. The lithology has little influence on its distribution, with caprock missing and no unified oilgas interface. Rock composition and its structure changes lead to a decreasing physical property, which is the leading factor in sealing the oil reservoir. The safety limit to the water boundary is proposed to be 150m in allocating wells in accordance with actual steam stimulation wells, SAGD production wells and well temperature monitoring data.
