彩南油田九井区人工裂缝系统研究

彩南油田九井区储层属于中孔特低渗储层，为了形成产能进行了整体压裂。整体压裂造成地下人工裂缝发育，储层含水急剧上升，油水关系复杂，产量递减快等现象。为了弄清人工裂缝系统的分布状况及发育程度，在对全区人工裂缝系统分析的基础上，根据压裂资料进行了人工裂缝系统评价，提高了人工压裂裂缝系统的认识，对油田注采调整措施起指导作用。

Study on Artificial Fracturing System of Well-Block 9 in CAINAN Oil Field

The reservoir in well block 9 is middle porosity and specially low permeability one, fracturing was implemented in order to builds up productivity. The fracturing gave rise to the development of artificial fractures underground, water cut in reservoir increasing sharply, relationship of oil and gas getting complicated and productivity decreasing quickly. In order to identify the distribution and development of artificial fractures the artificial fractures system is evaluated with fracturing data, the knowledge of artificial fractures system is improved on the base of analyzing artificial fractures system on the whole area, which will guide to injection and production.
