以Q区块的QS7井、B区块的BB7井和BB8井为分析对象，根据对沉积环境、岩性、物性、含油性以及测井曲线的研究发现，上述3口井在东河塘下砂岩段的储层特征很相似。通过对声波测井曲线分析和钻井过程中泥浆参数分析，发现了目的储层附近的地层孔隙压力变化状况，得出了在钻进过程中BB7井东河塘下砂岩段储层受到污染从而是导致试油结果不理想的原因。

We took Q block ,B block QS7 well BB7 well and BB8 well as analysis objects based on the research foundings on sedimentary environment ,lithologic character ,physical property ,oil-bearing property and logging curves ,found that 3 wells in the Donghe sandstone section of the Tangxia reservoir characteristics are very similar .Through the analysis of acoustic logging curves and drilling mud parameters ,we found that the reservoir pollution during BB7 well under the Donghetang sandstone is the cause of unideal oil results .
