神泉池田是一个典型的复式油田。纵向上,包括侏罗东、白垩系和第三系下、中、上共五个油藏。横向上发育12个含油断块。各断块之间油水系统各异,油气富集程度不均。自1996年实施滚动勘探开发方案以来,不仅陆续发现了神213、神220等八个新的含油断块,而且发现了第三系中、上两个新油藏。使油田的储量规模逐年增加,产能由最初的1×104t扩大到11×104t,取得了良好的经济效益。总结此类油气田的油气聚集特点及其主要控制因素和滚动勘探开发一体化的技术思路、政策与运作方式,具有重要的实用价值。
Shinsen Ikeda is a typical double oil field. Longitudinal, including the Jurassong, Cretaceous and Tertiary, the middle and on a total of five reservoirs. Laterally developed 12 oil-bearing fault block. Oil and water systems vary among fault blocks, and the degree of oil and gas accumulation is uneven. Since rolling program of exploration and development was implemented in 1996, not only eight new oil-bearing blocks such as God 213 and God 220 have been discovered, but also two new and upper third reservoirs have been discovered. As a result, the reserves of oilfields have been increased year by year, and the production capacity has been expanded from 1 × 104t to 11 × 104t, which has achieved good economic benefits. It is of great practical value to summarize the characteristics of hydrocarbon accumulation in this kind of oil and gas fields and their main controlling factors, as well as the technical ideas, policies and operation methods for the integration of rolling exploration and development.
