秦家屯油气田勘探成果及油气评价
|
摘要
秦家屯构造位于十屋断陷东部斜坡区的秦家屯———艾家窝堡构造带上 ,此构造带属于十屋断陷次一级构造单元。秦家屯构造勘探油气可分三个阶段 ,即 :普、概查阶段、详查阶段、开发阶段 ,前两个阶段为二维地震勘探阶段 ,开发阶段为三维地震勘探阶段 ,查清了构造、断裂。根据构造特征及油气条件预测 ,秦家屯构造是一个较好的含油气构造 ;并应用DIPOG技术对油气的富集区和富集层系进行预测 ,收到较好的效果。以此为依据布钻均获得工业油气流 ,并形成了一定产能 ,取得了十屋断陷外围地区油气勘探的突破 ,扩大了油气勘探范围。目前 ,秦家屯构造已形成相当开发规模的油气田
Located in Qinjiatun Aijiawo structural belt in the eastern slope of Shiwu fault depression,Qinjiatun structure belongs under the secondary structural unit in Shiwu fault depression.The exploration of Qinjiatun structure can be divided into three stages:reconnaissance,detail survey and development.For the first two stages,the 2 D seismic survey was used and for the development stage,the 3 D seismic survey was adopted,finding out the structure and fault.According to the structural feature and forecast of oil and gas bearing condition,Qinjiatun structure should be a better oil and gas bearing one.The forecast of the hydrocarbon abundance zone and horizons was made by use of DIPOG technique and a good result was obtained,and on the basis of which,the wells spaced in this structure all gained commercial oil and gas flow and formed a certain productivity,obtaining a breakthrough in the oil and gas exploration in the periphery of Shiwu fault depression and extending the scope of oil and gas exploration.At present,Qinjiatun Structure has become a fairly large oil and gas field.
