The conclusions are following : 1 . the basic factors influencing formation compression are thickness and density of overburden ( including fluid ) and behavior to enclose fluid of the formation 主要取得了以下认识： 1影响地层压力的基本因素是该岩层的上覆岩层(含流体)的厚度、密度以及该岩层封闭流体的特性。
This paper analyzes the cementing quality of newly drilled wells and rft in east transitional zone in xing 10 - 11 area and proves the existence of abnormal high pressure horizon in the reservoirs of this oil zone 摘要通过对杏十十一区东部过渡带外扩井区新钻井固井质量的分析及裸眼地层压力测井( rft )结果，证实该区油层段有异常高压层存在。
This paper introduces a method for determining average formation pressure in homogeneous gas wells and gas wells with boundary and formation heterogeneity , checked by actual measured pressure value , this method is proved to be simple and effective 本文介绍了均质及存在边界或地层非均质气井平均地层压力的确定方法，经实测压力值检验，证实方法是简易有效的。
Pressure separation is usually controlled by the following factors , such as subsidence rate , sediment types and diagenesis during the diagenetic evolution , as a result the pressure gradient is uncontinuous 地层压力分隔化是由于沉积物在成岩演化过程中受各种因素，如沉积速率、沉积物类型以及成岩作用的影响，使地层中的流体压力梯度呈现出随深度变化不连续的一种现象。
Researches show there are many types of strata pressure , super pressure in certain depth below the bottom of the jurassic stratum , and also overpressure in the whole jurassic stratum in central and southern of mosuowan salient 研究表明该地区地层压力类型丰富，侏罗系底部及以下地层在凹陷内一定深度以下普遍发育高压，在莫索湾凸起的中南部侏罗系则整体处于超压状态。

In the condition of depletion development , its formation pressure decrease , amplitude can be 3 times of the common gas reservoirs , so the study of stress sensitivity of the reservoir rock and its effect on production performance has a great significance 在衰竭式开采条件下，其地层压力降幅可为普通气藏地层压力降幅的3倍以上，因此研究储层岩石应力敏感性及其对生产动态的影响意义重大。
Based on single well process , the influence of reservoir parameter changes , such as permeability , reservoir thickness , average formation pressure , deformation factors on well productivity were studied by using the model under the depressure condition 最后，以单井为对象，应用建立的数学模型研究了降压开发条件下，渗透率、油层厚度、平均地层压力、形变因子等储层参数变化时对油井产能的影响规律。
5 . the most common types of oil - gas traps in mahu depression are lithological traps together with the complex traps derived from them that controlled by lithology , anticline , fault and over pressure of strata , etc . favorable prospecting targets of mahu depression are pointed out 5 、玛湖凹陷油气圈闭类型主要是以岩性圈闭为主的隐蔽圈闭，以及受岩性、背斜、断层、地层压力条件等控制的复合圈闭。
