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。

Submember A, showing lower organic carbon and higher iron contents than the other submembers, deposited in oxygenated bottom waters.

心组红岗段黑色页岩的黄铁矿有成岩黄铁矿和同生黄铁矿两种成因组分。

Subordinately come the moderately compacted and moderately cemented DRF3-type reservoirs in the Kongdian Formation, intensely compacted and moderately cemented DRF5-type reservoirs in the middle submember of the second member of the Kongdian Formation, and slightly compacted and moderately cemented DRF1-type reservoirs in the lower submember of the first member of the Kongdian Formation.

潍北油田孔店组储层主要属中压实中胶结的 DRF3型，其次是孔二中亚段发育的强压实中胶结的 DRF5型与孔一下亚段发育的弱压实中胶结的 DRF1型，局部出现其它三种类型的成岩相。

Different characteristics and mechanisms of these models and their mutual relations are discussed; thus the essential relation between syngenetic and epigenetic processes are preliminarily clarified.

本文归纳了这类铜矿的3种成因模式，即&沉积－成岩&、&沉积－喷气&和&沉积－改造&模式，讨论了它们的不同特征和机制，以及三者之间的相互关系。

For organic-poor sediments, pyrite was of syngenetic and diagenetic.

对于低有机质样品，黄铁矿由同生和成岩组分组成。

Organic carbon-limited diagenetic pyrite added to the earlier formed syngenetic pyrite, which was controlled by the time that iron minerals remained in contact with H2S in anoxic waters.

其中以成岩黄铁矿为主，其形成过程主要受有机质限制，而同生黄铁矿受铁矿物与H2S接触时间的限制。

The secondary pores of the sandstones were formed by the dissolution of the aluminosilicate, tuffaceous interstitial material and carbonate minerals effect by the carbonic acid and organic acid produced in late diagenesis stage. Hydrocarbon emplacement and tectonic thermal event act a positive role in the preservation of the primary pore and the formation of the secondary pores.

砂岩次生孔隙主要是成岩晚期阶段的碳酸以及有机酸对长石等硅酸盐矿物、凝灰质填隙物以及碳酸盐矿物的溶蚀造成的，油气侵位及构造热事件对原生孔隙的保存及次生孔隙的形成起到了积极作用。

For the Sibao group is got here by Sm-Nd isochron method dating the mafic-ultramafic whole rocks.

Based on the analysis of sediments and diagenesis of YangXin Series, author studied systematically all types of holes and fractures including stracture fissures, secondary corrosion cavities, contract holes and crevices, unloaded fissures, regionalrifts crush cracks (mechanical, hydraulic and oil-gas divulsional), seperate fissures in layres, collapse breccia′s clinks and seam lines, etc,.

作者在对阳新统沉积及成岩后生普通化的分析基础上，全面系统地分析了包括构造裂缝在内的各种孔洞缝类型，如次生溶蚀孔洞、收缩成因孔缝、卸荷张缝、区域裂缝、压裂缝（机械压裂、水力压裂、油气扯裂）、层理脱空缝、垮塌角砾间孔缝、缝合线等。

According to the geochemistry of fluid inclusions and the field observation, the mineralizing physical-chemical conditions and fluid evolution process are studied.
