Because the original oilfield development technology uses a single well, the efficiency of the single well is very low, which results in the deterioration of the effect in the development process of many oilfields and the loss in oilfield development. Therefore, in order to improve the benefit of oilfield development and the effect of water flooding development, this paper makes an in-depth study on the water-stable and oil-efficient development of high-water-cut and later-stage complex fault-block oilfields.展开更多

Three insecticides (methamidophos,Shachongshuang and triazophos) were used to control the rice leaffolder Cnaphalocrocis medinalis and rice striped stemborer Chilo suppressalis in rice fields during 18—27 days after transplantating. The impacts of timing and insecticides on the population development of brown planthopper Nilaparavata lugens was surveyed by direct counting on the plants or by tapping method.展开更多
