乾东～孤店地区已进入了寻找隐蔽油气藏(如低孔低渗油气藏)的阶段,流体识别研究需深入细致,利用压汞、核磁等资料将该区储层孔隙结构分成四类,按不同孔隙结构、不同沉积微相建立孔隙度、渗透率解释模型,参数解释精度明显提高。在低孔低渗油气层成因机理的基础上,利用多参数评价方法充分研究储层的孔隙结构,充分分析低孔低渗储层岩矿、岩性及地层水等,对该区域进行分区块、分岩性的评价。
The area from Qidong to Gudian has entered the stage of searching for subtle reservoirs (such as low porosity and low permeability reservoirs). Research on fluid identification needs to be studied in detail. The pore structure of reservoirs in this area is divided into four categories by using mercury intrusion and NMR data. According to different pore structures and different sedimentary microfacies, the porosity and permeability models are explained, and the precision of parameter interpretation is obviously improved. Based on the genesis mechanism of low-porosity and low-permeability oil and gas reservoirs, the multi-parameter evaluation method is used to fully study the pore structure of reservoirs, fully analyze the rock and mine, lithology and formation water of low porosity and low permeability reservoirs, , Sub-lithology evaluation.
