【摘要】：地溫-地壓系統(tǒng)(以下簡(jiǎn)稱溫壓系統(tǒng))控制油氣的生成、運(yùn)移和聚集,為明確文昌A凹陷溫壓系統(tǒng)特征及其與油氣成藏的關(guān)系,基于地溫和地壓實(shí)測(cè)數(shù)據(jù)及聲波測(cè)井等資料,利用溫壓系統(tǒng)原理,對(duì)珠江口盆地文昌A凹陷的地溫場(chǎng)、地壓場(chǎng)及溫壓系統(tǒng)特征進(jìn)行剖析,從油氣的生成、保存及分布角度探討溫壓系統(tǒng)與油氣成藏的關(guān)系。研究表明:文昌A凹陷地溫梯度較高,平均為33.8℃/km,有利于有機(jī)質(zhì)的成熟與烴類的生成;泥巖欠壓實(shí)段集中在珠海組、恩平組,強(qiáng)化了油氣的封蓋作用;珠江組泥巖不發(fā)育異常壓力,以毛細(xì)管壓力封閉為主;凹陷發(fā)育高壓型復(fù)式溫壓系統(tǒng),上、下2套溫壓系統(tǒng)的流體能量差較大,油氣以垂向運(yùn)聚為主,淺部靜壓型溫壓系統(tǒng)內(nèi)部最利于油氣富集成藏,恩平組含油氣系統(tǒng)是最重要的勘探對(duì)象。該研究對(duì)珠江口盆地的勘探有一定的指導(dǎo)意義。
[Abstract]:The geothermal pressure system (hereinafter referred to as the warm pressure system) controls the generation, migration and accumulation of oil and gas. In order to clarify the characteristics of temperature and pressure system in Wenchang A sag and its relationship with oil and gas accumulation, it is based on the measured data of ground temperature and ground pressure and acoustic logging, etc. Based on the principle of temperature and pressure system, the characteristics of geothermal field, ground pressure field and temperature pressure system in Wenchang A depression of Zhujiang River mouth basin are analyzed, and the generation of oil and gas is analyzed. The relationship between temperature and pressure system and hydrocarbon accumulation is discussed in terms of preservation and distribution. The results show that the geothermal gradient of Wenchang A depression is relatively high, with an average of 33.8 鈩，
