今后要研究钻井液侵入与孔隙结构对油层电性质和电法测井响应规律的影响，采用"及时测井"和压力梯度测井等技术措施；测井计算饱和度技术已日趋成熟，但需采用高精度数控测井等先进适用技术和更精细的"岩心刻度测井"解释方法，进一步提高精度，以满足低孔、低渗储集层和裂缝型复杂岩性储集层的更高要求。

Changbei gas field is a river lothology-stratigraphic trap gas pool on the west trend monocline background, it is located in the east of the basin, it has thin bed, low-porosity, low-permeability, low-pressure, low-deliverability character and develop difficulty(HeGuang-huai, 2002), especially to develop this thin bed and unhomogeneity seriously river sandbody gas pool is much difficulty.

长北气田位于盆地东部，属于西倾单斜构造背景上的河道岩性-地层圈闭气藏，具有薄层、低孔、低渗、低压、低产和非均质性强等特点，开发难度大，尤其是利用水平井开发如此薄层的非均质性严重的河道砂岩气藏难度更大。

As is low porosity and low permeability gas reservoir in Daniudi Gasfield and the influence of the drilling and geologic conditions on it, the total hydrocarbon values in wellsite gas logging could not accurately reflect reservoir gas bearing properties, and the interpretation and evaluation accuracy was decreased.

大牛地气田为低孔、低渗油气藏，由于钻井与地质条件等因素的影响，现场录井随钻全烃值不能准确反映储集层的含气性，降低了解释评价的准确性。

The results shows: the energy of elastici,disolved-gas drive and edge water drive in reservoir is plenty, but the physical properties of reservor are poor,crude oil viscosity is low and mobility is big, so it is difficult to develop by injecting waer.

对典型的特低渗超高压深层边水油藏文88块的开发方式进行了研究，研究表明：油藏弹性溶解气驱和边水驱能量较充足，油藏物性差、原油粘度低，流度较大，难以实现注水开发，而利用天然能量开发地质、工艺、经济上皆可行。

The sand body of channel in the middle sublacustrine fan has good porosity and is favorable reservoir.

利用东濮凹陷桥口地区的地质、测井和化验分析资料，从沉积微相、成岩作用、岩石结构等多方面入手，对其储层物性特征和控制因素进行了研究，指出桥口深层气藏湖底扇中扇辫状水道砂体物性较好，为有利储集层；该储层孔隙类型以次生溶蚀粒间孔隙为主，岩石粒度较细、分选中—差、以点—线接触为主；片状或弯片状喉道所占份额较大，造成储层低孔低渗；受溶蚀和交代作用的影响，部分层位次生孔隙发育，深层中也存在物性较好的储层。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征，研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪；N1层属于低孔、特低渗储层，孔隙类型以原生、次生粒间溶孔为主；分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用；进行了储层评价与有利相带预测，将储层分为三类并划分了有利区带、较有利区带，认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带，储层以Ⅰ、Ⅱ类为主。

Low porosity and permeability of fault rock belt prevents oil and gas from lateral migration traversing through faults.

断裂带内部结构具有分带特征，包括破碎带和裂缝密集带，破碎带中有黏结力断层岩带低孔低渗有效阻止油气穿越断层侧向运移，断层岩发育的断层侧向应该是封闭的。

In greywacke, the content of clay mineral often higher than 15%, clay mineral come from former clay mineral in sediments and their transformation. Clay minerals show plasticity. Clay mineral can damage the pore content of reservoir through distorting and filling into pore easily. These reservoir show low pore content and low permeability.

杂砂岩中的粘土矿物主要是沉积原生粘土矿物和原生粘土矿物转化形成的新生粘土矿物，粘土矿物在储集层中主要表现为可塑性，容易压实变形并充填到孔隙当中损害储集层物性，储集层物性主要表现为低孔低渗。
