以某储气库含硫注采井井下安全阀及井口主阀失效井喷为例,选用直观、物理量间关系容易推演高斯正态扩散模型,对不同注采时期和不同气象条件下硫化氢扩散伤害距离进行数值计算.结果表明,储气库含硫注采井发生井喷后,正常注采周期的不同注采阶段下风速是硫化氢扩散的主控因素;下风向和横风向伤害距离差异大,在相同气象条件下,风速越大(大气越不稳定)伤害距离越小,风速增大伤害距离与风速敏感度降低.

室内钻井液动态损害评价实验往往在较短时间内完成,与现场实际钻井过程不符.利用高温高压动态损害评价仪,模拟现场实际钻井过程,将被钻井液损害后的岩芯浸泡在钻井液滤液中一定时间后取出返排,评价不同浸泡时间对返排效果的影响程度.实验结果表明:随着钻井液滤液浸泡时间的增加,油基钻井液体系的返排恢复率变化不大,水基聚合醇体系的返排恢复率有下降的趋势；短时间浸泡时变化不大,长时间浸泡后返排效果明显变差；无固相体系的总体趋势是增加的.钻井液滤液浸泡时间对返排效果的影响主要与钻井液性质、储层特征、储层损害机理等因素有关.

In order to predict the reservoir quality of Well Jin 310 in Jin 1 well block of Liaohe Depression of Bohai Bay Basin before drilling,the diagenetic stages of the Member 2 of Paleogene Shahejie Formation were predicted by diagenetic modeling,and the reservoir porosity of the Member 2 of Shahejie Formation was predicted after the porosity prediction model was established considering the integrated effects of sedimentary facies and diagenesis on the porosity of reservoirs.As the results show,secondary pore was well developed in the reservoir located in the middle diagenetic stage A of the Member 2 of Shahejie Formation,and the absolute error between predicted porosity and measured porosity is only 1.33% in the reservoir with the content of filling materials of 16.13%.Therefore,the method of predrilling reservoir quality prediction considering integrated effects of sedimentary facies and diagenesis on reservoir quality could be applied to the exploration deployment of pre-exploration wells.

VSP logging,a quickly developed technology in recent years,plays an important role in extracting seismic parame-ters such as geologic formation,formation velocity and seis-mic wavelet. Compared with conventional seismic technolo-gy,VSP has the characteristic of high accuracy. Based on the analysis of the technical principles and technical advanta-ges of VSP logging technology,seismic data collection,pro-cessing and interpretation and relative geologic study on some complicated fault-blocks of Jinzhou oilfields have been carried out.
