岔河集油田有多个受构造、岩性双重因素控制的中低渗透复杂断块油藏,其主要储集层为河流相沉积。油田20余年的开发历程是典型的滚动勘探开发过程。通过精细科学的地质研究,不断的实践和认识,制定出与其油田地质特点相适应的开发方针,完善了井网部署与加密、产吸剖面调整、油水井配套综合治理等一系列开发对策,并取得了比较好的开发效果。岔河集油田的开发实践对于类似油田开发不乏成功的经验。

There are several complex middle to low porosity and low permeability oil reservoirs in the Chaheji oil field, dominated by dual factors of structure and lithology, the reservoir rocks of the oil-bearing formations are mainly of alluvial sediments. The 20 years of development history of the reservoirs has shown a typical procedure of successive exploration and development. Through high précised geological interpretation and successive cognitions, policies suitable to the geologic features of the oil reservoirs were established, and development policies such as well network perfection and intensification, adjustment of the oil pay zones and water zones in individual well sections, systematic treatments on the whole water injecting and oil producing wells, were proved to be effect, and fruitful results were achieved. These achievements in Chaheji oil field are inevitably credible and helpful to the development practice of other similar reservoirs.
