葵花岛油田储层流体识别方法研究

针对葵花岛油田在盐水泥浆条件下准确识别储层流体存在一定的难度,为了不断提高该油田储层流体识别的符合率,本文充分利用该油田比较丰富的试油投产资料及3700测井资料,开展了该油田储层流体识别方法研究,建立了该油田油气水层及气层识别图版,同时应用模糊逻辑方法建立了葵花岛油田模糊逻辑储层流体识别模型,并应用该模型对该油田内各井进行储层流体识别,最后结合上述图版及模糊逻辑储层流体识别成果,综合划分了该油田各井的有效厚度,重新计算了原油天然气地质储量,圆满完成了葵花岛油田的储量套改工作。

Researches on the Identification Method of Reservoir Liquids in Kuihuadao Oilfield

Because it is difficult to identify the reservoir fluid accurately under saline mud condition in Kuihuadao oilfield, we have carried out a research on the method of identifying reservoir fluids in the oilfield using plenty of production test or production data and 3700 logging data to improve the coincidence rate. We established a plate of oil, gas and water layers and a gas layer identification plate of the oilfield. We also set up an fuzzy logic model to identify the reservoir fluids in Kuihuadao oilfield by using the fuzzy logic method. It was used in each well of the oilfield. Finally according to the plate and the identification result with the fuzzy logic method, we divided the effective thickness of the reservoirs in each well and recalculated the geological reserves of crude oil and natural gas. We have finished the reserves calculation of Kuihuadao oilfield.
