埕岛油田（Chengdao Oilfield） Study on water offshore oilfield ---- shenglichengdao Wang Qike (200804010125) Chengdu University of Technology Energy Institute of Petroleum Engineering Department A preface: With the development of oil fields, the perfection of the underground reservoir characteristics, fluid properties, near the borehole is changing, timely and correctly grasp the dynamic changes of the reservoir, and the dynamic analysis of the system, it is an important basis for improving reservoir adjustment and recovery work. Well test plays an important role in the development of oil and gas, it can measure the reservoir development process and has a large number of underground reservoirs reflect dynamic features of the representative, the first hand information is an important means to realize and evaluate the reservoir dynamic analysis and forecast, and through the whole process in the whole oilfield development. Two. The geological background of Chengdao Oilfield Extremely shallow sea Chengdao oilfield is located in the Gulf of southern Bohai, the regional structure is located in the Bozhong depression and Jiyang depression at the intersection of North and Southeast end of the Lower Uplift, southwest to the north and north depression fault and nirvana adjacent, plunging in North Bozhong depression and depression in the south from the pile of East Coast 3km.. Victory the sea Chengdao oilfield is the first year of production development of China in the shallow water area invested more than 2 million tons of large oil. The Guantao formation reservoir of proven oil reserves accounted for 76.8% of the oil reserves, oil output accounted for 72.7% of oil production, is the main development of Chengdao Oilfield strata. Guantao formation reservoir is developed in the first third lines of Qianshan on the basis of the large drape anticline, the reservoir is fluvial facies, non oil serious homogeneous high permeability and high saturation lithologic layered sandstone reservoi
