濮城油田卫42-43块低孔低渗油藏整体改造

Overall Reconstruction of Low Porosity and Low Permeability Reservoirs in Block Wei 42-43 of Pucheng Oilfield

濮城油田卫42-43断块属于典型的低孔、低渗、非均质油藏,采取常规开发方案无法对其进行经济有效的开采。结合地应力监测资料,采用优化井网部署技术,从地质、测试、采油工程及压裂工艺技术方面不断深入研究,实施整体压裂改造,形成了一套较成熟的油藏开发工艺。工艺的实施取得了良好的经济效益,为这一类非均质低孔低渗油藏整体开发探索出一条可行之路。

Fault Block Wei 42-43 in Pucheng Oilfield belongs to a low porosity,low permeability heterogeneous reservoir,it is hard to be produced with conventional production scheme.In combination with in-situ stress detection data,the technique of optimal pattern arrangement,the study of techniques of geology,detection,oil production engineer ing and fracturing are further deepened to conduct an overall reconstruction of fracturing,thus a set of more matured techniques for reservoir development are proposed,of which better economic benefits are achieved and a feasible way is established for the development of these kinds of reservoirs.
