K油田位于哈萨克斯坦南图尔盖盆地阿克赛隆起带上,主要产层为白垩系底砂岩及侏罗系河道砂。油田区南北跨度较大,油藏类型多样,砂体边界识别困难。该油田在2000年之后逐步投入开发,但在开发过程中发现相邻井的出油情况差异较大,油水关系复杂,油田需要提高对油藏的识别精度来应对新一轮增储上产及井网调整问题。利用敏感属性分析、3D可视化模块、地质统计反演等技术,重新认识和评价了K区油藏特征,识别区内多个独立油藏,厘清油藏间的油水关系,总结该区不同油藏类型的含油气规律,就目前困扰K油田勘探开发工作的问题给出解答。
K Oilfield is located on the Aksai uplift belt of the South Turgai Basin in Kazakhstan. The main production zones are Cretaceous bottom sandstone and Jurassic channel sand. The oilfield area has a large span between north and south with various types of reservoirs, and the boundary of the sand body is difficult to identify. The oilfield was gradually put into development after 2000. However, during the development process, it is found that there is a big difference in oil production between adjacent wells and the relationship between oil and water is complex. Therefore, the oilfield needs to improve the identification accuracy of the reservoir to deal with the new round of production increase and increase Well network adjustment problem. By using the technologies of sensitive attribute analysis, 3D visualization module and geostatistical inversion, the characteristics of K reservoir are re-recognized and evaluated. Many independent reservoirs are identified and the relationship between oil and water in the reservoir is clarified. Type of oil and gas laws, on the current troubled K oil exploration and development work to answer questions.
