Abstract

Abstract: The marine origin gas pools in Tarim Basin are distributed in Tabei,Tazhong and Bachu uplifts. They have their respective characteristics on gas composition,phase and non-hydrocarbon composition.Analysis of three typical gas pools:gas condensate pool of Well Lunnan 59 Carboniferous and Well Tazhong 1 Ordovician and dry gas pool of Well Ma 4 Ordovician. Identified that all of the gas are generated from the cracking of Kerogen and crude oil.The three gas pool modes are built by comprehensive geological analysis: 1)the dry gas generated from cracking of Kerogen charged the paleo oil pool to form the gas condensate pool; 2)the cracking of oil to gas in paleo oil pool to form gas condensate pool and 3)the dry gas generated from cracking of oil to gas in paleo oil pools migrated to a new trap to form dry gas pool.

Key words: Tarim, marine, gas pool, condensate gas, dry gas, pool formation mode

摘要： 塔里木克拉通盆地海相成因的天然气藏分布于塔北、塔中和巴楚隆起上,它们在气组分、相态、非烃组分和碳同位素上具有各自的特征。通过对轮南9井石炭系、塔中1井奥陶系凝析气藏和玛4井奥陶系干气气藏三个典型气藏中天然气成因分析,识别出干酪根裂解气和原油裂解气,综合地质分析,总结出干酪根晚期裂解干气充注古油藏形成凝析气藏;古油藏晚期发生内部原油向气的热裂解形成凝析气藏;古油藏裂解形成的干气运移至新的圈闭形成干气气藏等3种类型的气藏成藏模式。
