STUDIES OF ACCUMULATION STAGES OF SILURIAN GAS-BEARING RESERVOIRS IN WELL KONGQUE 1 IN THE TARIM BASIN

摘要: 近年来,塔里木盆地东北缘烃源岩高—过成熟区油气勘探获得重要发现,已在几口井中获得工业气流或油气显示,位于孔雀河斜坡维马克—开屏构造带上的孔雀1气藏是其中一个代表性的重要气藏。通过流体包裹体实验法,探讨了孔雀1井志留系含气储层的成藏期次。实验结果表明,孔雀1气藏历史上主要有2期成藏过程:第一期为加里东晚期沉积埋藏阶段古油藏形成时期(380~365 Ma);第二期为构造抬升阶段,源于古油藏热裂解成因的天然气成藏期(325~315 Ma)。对比英南2气藏的成藏时间可以看出,孔雀1气藏形成时间较早,早先建立起的孔雀河地区晚期成藏特点不具有普遍性,不同构造带具有不同的成藏历史特征。对孔雀河地区成藏历史取得的新认识,对该地区下一步油气勘探具有重要的指导意义。Abstract: Oil and gas explorations in the northeast of Tarim Basin are quite successful recently with several commercial gas accumulations discovered in high and over-matured source region.The Kongque 1(Kq 1) Gas Field,situated in the Weimake-Kaiping Structural Belt of the Kongquehe Slope,is a representative gas accumulation.With applications of organic inclusions,accumulation stages of Silurian gas-bearing reservoirs in Well Kq 1 are determined.According to experiment results,charge history of Well Kq 1 can be divided into 2 stages.The first stage is the formation time of palaeo-petroleum reservoir in de-positional phase of late-Caledonian movement(350-365 Ma).The second stage is the gas formation time during tectonic uplifting stage(325-315 Ma).Gas is thermal cracked gas derived from palaeo-petro-leum reservoirs.Compared with accumulation time of Well Yingnan 2,formation time of Well Kq 1 is earlier.Late period accumulation characters in the Kongquehe area is not general.Different tectonic belts have different oil-and-gas accumulation histories.New cognitions about formation stages of oil-and-gas are important for further explorations in the Kongquehe area.
