%X 延长组地层发育时间长，为油气资源提供了良好的生油、聚集及储存场所，但该区块储集层有很强的非均质性，物性差，地层结构复杂。长9作为含油层之一，为了更准确地探明落实该区长9含油层位和储层特点，设计最大井深2400 m的探井，依据该区一些井位的录井和测井资料，进行地层标志层对比和油水层划分，预测吴起油田长官庙油区长9油层探井，储层岩性主要是暗色泥岩、页岩夹灰色粉–细砂岩，总厚度为80~130 m；长9<sup>1</sup>、长9<sup>2</sup>、长9<sup>3</sup>深度为2220.9~2262.2 m、2262.2~2299.9 m、2299.9~2337.8 m；出油水井段为2235~2240 m和2230~2235 m。<br />
The long development time of Yanchang Formation provides a good place for oil generation, accumulation and storage of oil and gas resources, but the reservoir in this block has strong heterogeneity, poor physical property and complex formation structure. Chang 9 is one of the oil-bearing reservoirs. In order to more accurately identify and implement the characteristics of Chang 9 oil-bearing reservoirs and reservoirs in this area, an exploration well with a maximum well depth of 2400 m was designed. Based on the logging and logging data of some well locations in this area, marker formation correlation and oil-water layer division were conducted to predict the exploration well of Chang 9 oil layer in Changmiao oil area of Wuqi Oilfield. The reservoir lithology is mainly dark mudstone, shale mixed with gray silt-fine sandstone, with a total thickness of 80~130 m; Chang 9<sup>1</sup>, Chang 9<sup>2</sup>, Chang 9<sup>3</sup><sup> </sup>are 2220.9~2262.2 m, 2262.2~2299.9 m, 2299.9~2337.8 m in depth; It is predicted that the oil-well interval is 2235~2240 m and 2230~2235 m.
