摘要:

近年来,鄂尔多斯盆地石油勘探在延长组下组合长 9 油层组获得了新发现,但对该致密油藏的研究仍处于起步阶段,认识的不足严重制约了致密油藏勘探开发。 根据钻井、测井及分析测试资料,对王洼子地区长 9 致密砂岩油藏成藏条件进行了分析,探讨了油藏富集规律及其勘探潜力。 研究表明,该区长 9 油层组具有较好的成藏条件,长 91 和长 93 已见多口高产井,石油勘探已有较大的突破。 烃源岩、沉积微相、优质砂体、鼻状隆起等几个因素的优化匹配是长 9 致密砂岩油藏勘探能够取得突破的关键。 据综合分析,洼 4 井区及洼 14—洼 11 井区成藏条件较好,为下一步的有利勘探区。

Abstract:

 New discovery has been achieved in tight sandstone in the exploration of lower assemblage of Chang 9 member of Yanchang Formation in Ordos Basin. But the research of tight reservoir is still in the initial stage, and the lack of awareness seriously restrict the exploration and exploitation of tight reservoir. According to the data of well logging, well drilling and laboratory test, this paper discussed the forming condition, enrichment rule and exploration potential of the tight sandstone reservoir of Chang 9 member in Wangwazi area. The result shows that Chang 9 oil reservoir set has good reservoir forming conditions, several high-production wells have been found in Chang 91 and Chang 93 strata, and it has great breakthrough of petroleum exploration. The hydrocarbon source rocks, sedimentary microfacies, high quality sand bodies, nose-shaped structure are the key for exploration breakthrough of the tight sandstone reservoir of Chang 9 member. Based on comprehensive analysis, Wa 4, Wa 14 and Wa 11 well fields are favorable areas for further exploration.
