ABSTRACT

煤成气是天然气的一个重要组成部分,是我国天然气勘探的新领域。煤成气与油型气的化学成分及运移、聚集规律基本相同。因此,含煤成气地层与含油型气地层的测井响应是相同的,用于勘探油型气的测井系列同样可以用于勘探煤成气。当然,根据测井资料不能直接区别煤成气与油型气。但是,多数煤成气与煤层有关,测井不仅是勘探气层的有效方法,而且也是勘探煤层的重要手段,可以通过煤层识别煤成气。我国某煤成气田采用的测井系列包括:补偿地层密度测井、补偿中子测井、井眼补尝声波测井、双感应-球形聚焦测井、自然电位测井、自然伽马测井、井径测井。利用测井信息识别砂岩气层的分辨率高于识别泥质砂岩气层的分辨率,但仍然能够发现泥质砂岩气层。一个砂岩气层的测试结果是:产气62.7万m~3/d,产油15.3m~3/d,产水6.8m~3/d。三个泥质砂岩气层的合试结果是:产气57万m~3/d,产油微量,产水3.3m~3/d。实践表明,将上述测井系列和识别煤成气的方法用于勘探煤成气,获得了显著的地质效果。

The resolution of a spontaneous potential log can be improved effectively bysubstitating annular electrode for point electrode. The relationship between an-nular electrode and longitudinal electric potential gradient is analysed and calcula-ted theorotically. This paper puts forward that there is a linear relation betweenthe enlargement rate of the longitudinal electric potential gradient and the resolu-tion. An experiment simulating the electric current fields in a borehole has beenperformed to check the theoretical results. Therefore, the theoretical basis of theannular electrode and the criterion determining its radius are confirmed.

将自然电位测井中的点电极改成环电极,可以有效地提高测井的分层能力。本文对环电极及环电极与纵向电位梯度的关系进行了理论分析和计算,提出了纵向电位梯度增大比与分层能力的线性关系,并用井内自然电流场的模拟实验对理论结果进行了验证,从而确立了环自然电位测井提高分层能力的理论依据,以及环电极半径的选取原则。
