The Main Controlling Factors and Exploration Thinking of Adjustment Reservoirs in Center of oft-com:office:smarttags" />JunggarBasin oft-com:office:office" />
In center of oft-com:office:smarttags" />JunggarBasin, the petroleum exploration aims at subtle and adjustment reservoirs and its exploration risk is high. According to the researches, the sedimentary background of Member 2 of Sangonghe Formation, Jurassic and the later evolution of Chemo paleo-uplift is the main controlling factors to the hydrocarbon adjustment. In view of different exploration targets, the author puts forward the following exploration thinking. In J1s22, the main target is to find structural (fault block and low amplitude anticline) reservoirs, while in J1s21, the main target is to find lithologic reservoirs. And according to this thinking, the authors obtained good effect in petroleum exploration practice of central JunggarBasin.
