Based on the pressure curve experiment, the physical characteristic of ore-bearing rocks of the Luoba lead-zinc deposit in the Qinling Xicheng deposit field shows small porosity, low permeability and bad link ostiole in the ore-bearing rocks series. The feature indicates that the physical characteristic of ore bearing is unfavorable for forming the Luoba lead-zinc deposit.

采用压汞分析技术对秦岭多金属成矿带西成矿田洛坝铅锌矿床含矿层各岩系的物性特征进行了研究，结果表明含矿层各岩系物性特征具有孔隙度小、渗透率低、孔喉连通性差的特点，这一特征对洛坝大型矿床的形成是极为不利的。

Iron deposit is concerned with spilite keratophyre, rich in Fe, Na〓O, Alternative types are similar-skarnization, Iron deposit is of aeromagnetic anomaly. Indexes of Cu, Pb-Zn deposits are contemporaneous fault, ore-bearing bed, volcanic rock with high potassium, volcanic structure, a serious of alternative in ore-bearing bed and under ore-bearing bed, high content of Pb, Zn, Ag, Cu, Cd, Ba, As, CaO, Fe, Mn, low Na〓O, Al〓O〓 in mineralizing body.

The invention comprises that:(1) an injectant containing air is formed and the injectant is injected into a manto (3) through an injection well (2) or a recovery well (1);(2) the pressure of the injection well (2) and the recovery well is kept (1) for a period of time so that the oil and the injectant are mixed into more uniform fluid;(3) the pressure of the injection well (2) and the recovery well (1) is decreased, the pressure of the manto(3) is decreased and the oil-containing mixed fluid is obtained from the recovery well (1) or the injection well (2);(4) the procedure of (1),(2) and (3) is repeated, the pressure fluctuation of the fluid in the manto (3) is realized until the oil recovery rate is less than the economic recovery rate.

本发明包括：①形成包含气体的注入剂，将注入剂通过注入井(2)或采收井(1)注入矿层(3)；②保持注入井(2)和采收井(1)的压力一段时间，使油分和注入剂混合形成比较均匀的流体；③然后降低注入井(2)和采收井(1)的压力，降低矿层(3)压力，并在采收井(1)或者注入井(2)获取含油混合流体；④不断重复步骤①②③，实现矿层(3)中流体的压力波动，直到石油的采收率低于经济开采率为止。

The invention is suitable for the oil production field and can be suitable for any manto so long as the displacement exploitation is possible; also the invention can be suitable for the manto that is unsuitable for the displacement exploitation due to the strong heterogeneity of the manto, which greatly breaks through the scope and recovery rate of the traditionally displacement exploitation method.

本发明适用于石油开采领域，适用于任何能够进行驱替开采的矿层；也适用于由于矿层非均匀性强烈而不适合进行驱替开采的矿层，大大突破传统驱替开采方法的范围和采收率。
