准噶尔盆地“八五”油气勘探成果及“九五”勘探设想

PETROLEUM EXPLORATION RESULTS DURING THE EIGHTH FIVE-YEAR PLAN AND EXPLORATION PROGRAMME IN THE PERIOD OF THE NINTH FIVE-YEAR PLAN

“八五”期间，在准噶尔盆地先后发现了彩南、石西、玛北、小拐等４个油气田和五区南油气藏，超额完成了“八五”计划所规定的油气储量增长任务。这些成绩是由于认真贯彻了“稳定东部，发展西部”、“油气并举”的石油工业工作方针，以新的油气勘探理论为依据，以先进的油气勘探技术为手段取得的。“九五”期间盆地的油气勘探应以盆地腹部为重点，继续深化西北缘斜坡区的勘探；以经济效益为中心，油气并举，力争在准东、昌吉凹陷东斜坡有新的发现；继续探查外围中小型盆地，攻克山前陡构造和深部钻探技术，为油气勘探准备新的接替区；应用盆地模拟、圈闭描述、油藏描述等三大评阶技术，不断改善资源储量序列结构，使油气勘探步入良性循环轨道。

During the Eighth Five-Year Plan,four oilfields(Cainan,Shixi,Mabei,and Xiaoguai)and one oil pool(in the southern District No.5) were discovered in Junggar basin,exceeding the plan of oil/gas reserves increase in the Eighth Five-Year Plan.These results benefit from the implementation of stratigies in oil industry″to maintain the oil production in the east and develop oil resources in the west″and″take equal efforts in oil and gas development″,along with new theories on petroleum exploration and advanced exploration techniques.During the Ninth Five-Year Plan,more efforts should be taken in the hinterland of the basin and attempts to new discoveries in the slope zone of northwestern basin continue.Goaling at better economic efficiency,oil and gas develop simultaneously for new discoveries in the eastern basin and eastern slope of Changji sag.Medium-to small-size basins in its periphery continue to be under survey,foredeep steep structures and deep drilling techniques should be deeply understood.These areas are expected to be new objectives of interest for exploration.Basin simulation,trap description and reservoir delineation techniques are used more and structures of reservoirs sequence improved so as to obtain a benign circulation of petroleum exploration.
