Huanghua 127 West Xinglongtai oil well is located at the southern slope of the western slope of the Liaohe River fault and is mainly Xinglongtai oil reservoir. The Xinglongtai oil layer is a set of sandstone and mudstone interbedded in the longitudinal direction. The rocks are mainly siltstone, fine sandstone and unequal sandstone. The cementation type is contact-porosity cemented cementation with an oil area of 0.4km2 and a geological reserve of 203 × 104t. The effective thickness of the reservoir is 23m, the average porosity is 32%, the average permeability is 3125μm2, the viscosity of crude oil is 16615mPa.S at 50 ℃.
