油气田开发过程中,尤其是注水开发,由于地层物性不同,黏土矿物含量不同,导致开发难度不同.本文是将有机小阳离子铵盐通过地面增加工艺流程,注水工艺中实现注入地层进行防膨.对黏土总含量较高,高岭石、蒙皂石相对含量高的区块进行注水整体防膨,来保证有效开发断块,减少出砂速度,降低压力突然升高井数,提高水井吸水能力,注水增油明显.可根据地面水井生产参数、监测和作业中数据进行综合分析进行周期防膨,及时调整地面生产运行参数、发现不正常井,进而降低地面运行成本,高效开发断块.

别古庄油田京11断块从1979年投入开发截至到2014年12月采出程度达到50．97％，综合含水达到90．6％，已经进入高含水开发后期。为了搞清油藏剩余油分布并进行化学驱试验，提高采收率和经济效益，对该油藏进行了开发数值模拟研究。通过采用Eclipse黑油模型，结合地质分析和油藏工程评价，在产油量、含水率和地层压力等历史拟合的基础上，针对化学驱设计了3套不同的调整开发方案，并对其开发指标进行了预测。通过预测结果分析，建议采用各项开发指标为最佳的调整方案，为合理开发京11断块油藏提供了依据。

本文针对华北油田二连地区的阿尔油田低孔低渗型油藏,分析了几个影响测井解释和认识的重点问题.影响该地区岩石物性的主要因素为中喉在整个吼道中所占的比例；利用微电极双曲线能够较好的提供地层渗透性信息；同时参考密度曲线,考察了区分自然产能层和压裂产能层的可能性.

There are high-capacity channels existed in Block Jing11, this causes violent water flooding in oil wells, greatly lower the water displacement efficiency, and is very harmful to oilfield development. By applying oxygen activation logging of pulse neutron and conducting plugging seal off the high-capacity channels according as oxygen activation profile, high-capacity channels are identified and harnessed, and good results are achieved.

In order to guide horizontal well drilling design and offer the basis for second oilfield development as well,cased-hole residual oil evaluation of 20 wells in Huabei oilfield Jing11 block has been done by using the Cased Hole Formation Resistivity Logging(CHFR).Analyzed are formation flooded conditions,log data quality and the oil-tested layers characteristics in the key wells,which shows that depressed resistivity means strong flooded layer;increased resistivity means middle-strong flooded layer;when the resistivity is steady,the flooding strength is stronger when the water injection result is better.On the basis of above analysis,the interpretation chart and standard of flooded layer in Jing11 block are worked out.The accuracy of re-interpretation of 18 wells in this area reaches 89.5%,showing that CHFR is an effective method to supervise the residual oil.
