预探井

东秋5井是一口典型的异常高压低渗透地层预探井。

Well Dong Qiu5 is a wildcat well with Abnormal High Pressure .

赵46井是晋县凹陷南部第一口钻遇潜山的预探井，在钻进中4154～4155.6m累计漏失泥浆达638m3。

Zhao-46 well is a wildcat well which met the burial hill in Jinxian Seg . The mud loss is 638 m3 during drilling 4154 - 4155 . 6 m.

在钻预探井前，利用亮点、AVO和道积分技术可有效识别这类含气砂岩。

Using bright spot , AVO and trace integration tool , such gas bearing sandstones can be effectively recognized before exploratory drilling .

在一口预探井进行了随钻检测地层可钻性的现场试验，证明该方法是有效的。

Test drilling is performed and shows that this method is effective .

模式识别在预探井钻前储层预测中的应用

Application of pattern recognition in reservoir prediction in PRE-EXPLORATORY wells before drilling

对探井、预探井、资料井应采用地层压力随钻检（监）测技术；

For pre-exploration and information ( data ) wells , pressure prediction while drilling technology shall be adopted .

不同勘探阶段二维、三维、预探井、评价井投资比例；

The proportion of 2D seismic prospecting , 3D seismic prospecting , preliminary prospecting well and appraisal well investment ;

不应依据有限的几口预探井的失利而否定某一地区的勘探前景，因为复杂盆地具有复杂而独特的油气成藏机理和分布规律。

The forth is explorative prospect of an area should not be denied based only on the failure of some wildcat wells , because complex basin has complicated and particular hydrocarbon accumulation mechanism and distribution pattern .

从非常规天然气的存在、工艺、工程等方面分析了预探井失效的原因，研究了深层致密气藏的异常渗流机理及其影响因素。

Failure reasons for wildcat wells were analyzed from the aspects of existing of the unconventional natural gas , technology and engineering . And abnormal percolation mechanism and its influencing factors in the deep-seated tight gas reservoirs were studied .
