平湖油气田储层及含油气预测

Prediction of Oil and Gas Reservoir in Pinghu Oil & Gas Field

平湖油气田是东海第一个开发的复合型油气田 ,主要含油气层段为渐新统花港组油藏 (H2 -H8)和始新统平湖组气藏 (P1 -P1 1 ) ,首期开发区为F1、F2断块 ,二期开发区为B1、B2断块。在平湖油气田开发过程中 ,针对花港组油藏波阻抗与岩性相关性好 ,而平湖组中下部波阻抗与岩性相关性不好的这种地质和地球物理特点 ,应用国内外先进的技术和方法 ,尝试多种方法预测储层及含油气 ,取得了较好的预测成果。

Pinghu oil & gas field, the first development oil & gas field in East China Sea, has Oligocene Huagang oil reservoir (H 2-H 8) and Eocene Pinghu gas reservoir (P 1-P 11 ). The fault block F1 and F2 are of the first phase for development and the block B1 and B2 are of the second phase to be developed. In the development wells of the first phase, the relation between impedance and lithology is good in Huagang formation and is bad in Pinghu formation. So many advanced techniques were applicated to predict the reservoirs of bath Huagang and Pinghu in Pinghu oil & gas field and had obtained good results.
