摘要
XC油区的主力油层属于低渗-超低渗储层,通过压裂作业来提高储层的渗透能力,是生产中的一个至关重要的环节。压裂效果的好坏能够直接影响到油田的后续产量。而对压裂裂缝进行监测,获取压裂裂缝的基本参数,是评价压裂效果的基础之一。本文采用最常用的人工裂缝监测技术-微地震法,对XC油区5口压裂井压裂缝进行了监测和分析研究,确定了地应力的方向,对该地区的后续压裂方案制定及井网部署具有一定的参考意义。
The main oil layer of XC oil region is low and ultra-low permeability reservoir.It is a rather significant part in production to upgrade the permeability of reservoir through fracturing treatment.The fracturing effect can affect the subsequent output of oil field.Monitoring fracturing fractures to obtain its parameters is the foundation for evaluating the fracturing effect.In this paper,fracturing fractures of five wells in XC oil region were monitored and analyzed by the fracture monitoring technique, micro-seismic method;and the direction of earth stress was ascertained,which can provide great reference for the constitution of subsequent fracturing program and the disposition of well network.
